THE ULTIMATE WEAPON
When star fights star,
is chaos the best defense?]
RED SUN RISING
The star Mira was unpredictably variable. Sometimes it was blazing,
brilliant and hot. Other times it was oddly dim, cool, shedding little
warmth on its many planets. Gresth Gkae, leader of the Mirans, was
seeking a better star, one to which his "people" could migrate. That
star had to be steady, reliable, with a good planetary system. And in
his astronomical searching, he found Sol.
With hundreds of ships, each larger than whole Terrestrial spaceports,
and traveling faster than the speed of light, the Mirans set out to move
in to Solar regions and take over.
And on Earth there was nothing which would be capable of beating off
this incredible armada--until Buck Kendall stumbled upon THE ULTIMATE
WEAPON.
JOHN W. CAMPBELL first started writing in 1930 when his first short
story, _When the Atoms Failed_, was accepted by a science-fiction
magazine. At that time he was twenty years old and still a student at
college. As the title of the story indicates, he was even at that time
occupied with the significance of atomic energy and nuclear physics.
For the next seven years, Campbell, bolstered by a scientific background
that ran from childhood experiments, to study at Duke University and the
Massachusetts Institute of Technology, wrote and sold science-fiction,
achieving for himself an enviable reputation in the field.
In 1937 he became the editor of _Astounding Stories_ magazine and
applied himself at once to the task of bettering the magazine and the
field of s-f writing in general. His influence on science-fiction since
then has been great. Today he still remains as the editor of that
magazine's evolved and redesigned successor, _Analog_.

I
Patrol Cruiser "IP-T 247" circling out toward Pluto on leisurely
inspection tour to visit the outpost miners there, was in no hurry at
all as she loafed along. Her six-man crew was taking it very easy, and
easy meant two-man watches, and low speed, to watch for the instrument
panel and attend ship into the bargain.
She was about thirty million miles off Pluto, just beginning to get in
touch with some of the larger mining stations out there, when Buck
Kendall's turn at the controls came along. Buck Kendall was one of
life's little jokes. When Nature made him, she was absentminded. Buck
stood six feet two in his stocking feet, with his usual slight stoop in
operation. When he forgot, and stood up straight, he loomed about two
inches higher. He had the body and muscles of a dock navvy, which Nature
started out to make. Then she forgot and added something of the same
stuff she put in Sir Francis Drake. Maybe that made Old Nature nervous,
and she started adding different things. At any rate, Kendall, as
finally turned out, had a brain that put him in the first rank of
scientists--when he felt like it--the general constitution of an ostrich
and a flair for gambling.
The present position was due to such a gamble. An IP man, a friend of
his, had made the mistake of betting him a thousand dollars he wouldn't
get beyond a Captain's bars in the Patrol. Kendall had liked the idea
anyway, and adding a bit of a bet to it made it irresistible. So, being
a very particular kind of a fool, the glorious kind which old Nature
turns out now and then, he left a five million dollar estate on Long
Island, Terra, that same evening, and joined up in the Patrol. The Sir
Francis Drake strain had immediately come forth--and Kendall was having
the time of his life. In a six-man cruiser, his real work in the
Interplanetary Patrol had started. He was still in it--but it was his
command now, and a blue circle on his left sleeve gave his lieutenant's
rank.
Buck Kendall had immediately proceeded to enlist in his command the IP
man who had made the mistaken bet, and Rad Cole was on duty with him
now. Cole was the technician of the T-247. His rank as Technical
Engineer was practically equivalent to Kendall's circle-rank, which made
the two more comfortable together.
Cole was listening carefully to the signals coming through from Pluto.
"That," he decided, "sounds like Tad Nichols' fist. You can recognize
that broken-down truck-horse trot of his on the key as far away as you
can hear it."
"Is that what it is?" sighed Buck. "I thought it was static mushing him
at first. What's he like?"
"Like all the other damn fools who come out two billion miles to scratch
rock, as if there weren't enough already on the inner planets. He's got
a rich platinum property. Sells ninety percent of his output to buy his
power, and the other eleven percent for his clothes and food."
"He must be an efficient miner," suggested Kendall, "to maintain 101%
production like that."
"No, but his bank account is. He's figured out that's the most economic
level of production. If he produces less, he won't be able to pay for
his heating power, and if he produces more, his operation power will
burn up his bank account too fast."
"Hmmm--sensible way to figure. A man after my own heart. How does he
plan to restock his bank account?"
"By mining on Mercury. He does it regularly--sort of a commuter. Out
here his power bills eat it up. On Mercury he goes in for potassium, and
sells the power he collects in cooling his dome, of course. He's a good
miner, and the old fool can make money down there." Like any really
skilled operator, Cole had been sending Morse messages while he talked.
Now he sat quiet waiting for the reply, glancing at the chronometer.
"I take it he's not after money--just after fun," suggested Buck.
"Oh, no. He's after money," replied Cole gravely. "You ask him--he's
going to make his eternal fortune yet by striking a real bed of jovium,
and then he'll retire."
"Oh, one of that kind."
"They all are," Cole laughed. "Eternal hope, and the rest of it." He
listened a moment and went on. "But old Nichols is a first-grade
engineer. He wouldn't be able to remake that bankroll every time if he
wasn't. You'll see his Dome out there on Pluto--it's always the best on
the planet. Tip-top shape. And he's a bit of an experimenter too.
Ah--he's with us."
Nichols' ragged signals were coming through--or pounding through. They
were worse than usual, and at first Kendall and Cole couldn't make them
out. Then finally they got them in bursts. The man was excited, and his
bad key-work made it worse. "--Randing stopped. They got him I think. He
said--th--ship as big--a--nsport. Said it wa--eaded my--ay. Neutrons--on
instruments--he's coming over the horizon--it's huge--war ship I
think--register--instru--neutrons--." Abruptly the signals were blanked
out completely.
* * * * *
Cole and Kendall sat frozen and stiff. Each looked at the other abruptly,
then Kendall moved. From the receiver, he ripped out the recording coil,
and instantly jammed it into the analyzer. He started it through once,
then again, then again, at different tone settings, till he found a very
shrill whine that seemed to clear up most of Nichols' bad key-work.
"T-247--T-247--Emergency. Emergency. Randing reports the--over his
horizon. Huge--ip--reign manufacture. Almost spherical. Randing's stopped.
They got him I think. He said the ship was as big as a transport. Said
it was headed my way. Neutrons--ont--gister--instruments. I think--is
h--he's coming over the horizon. It's huge, and a war ship I
think--register--instruments--neutrons."
Kendall's finger stabbed out at a button. Instantly the noise of the
other men, wakened abruptly by the mild shocks, came from behind.
Kendall swung to the controls, and Cole raced back to the engine room.
The hundred-foot ship shot suddenly forward under the thrust of her tail
ion-rockets. A blue-red cloud formed slowly behind her and expanded.
Talbot appeared, and silently took her over from Kendall. "Stations,
men," snapped Kendall. "Emergency call from a miner of Pluto reporting a
large armed vessel which attacked them." Kendall swung back, and eased
himself against the thrusting acceleration of the over-powered little
ship, toward the engine room. Cole was bending over his apparatus,
making careful check-ups, closing weapon-circuits. No window gave view
of space here; on the left was the tiny tender's pocket, on the right,
above and below the great water tanks that fed the ion-rockets, behind
the rockets themselves. The tungsten metal walls were cold and gray
under the ship lights; the hunched bulks of the apparatus crowded the
tiny room. Gigantic racked accumulators huddled in the corners. Martin
and Garnet swung into position in the fighting-tanks just ahead of the
power rooms; Canning slid rapidly through the engine room, oozed through
a tiny door, and took up his position in the stern-chamber, seated
half-over the great ion-rocket sheath.
"Ready in positions, Captain Kendall," called the war-pilot as the
little green lights appeared on his board.
"Test discharges on maximum," ordered Kendall. He turned to Cole. "You
start the automatic key?"
"Right, Captain."
"All shipshape?"
"Right as can be. Accumulators at thirty-seven per cent, thanks to the
loaf out here. They ought to pick up our signal back on Jupiter, he's
nearest now. The station on Europa will get it."
"Talbot--we are only to investigate if the ship is as reported. Have you
seen any signs of her?"
"No sir, and the signals are blank."
"I'll work from here." Kendall took his position at the commanding
control. Cole made way for him, and moved to the power board. One by one
he tested the automatic doors, the pressure bulkheads. Kendall watched
the instruments as one after another of the weapons were tested on
momentary full discharge--titanic flames of five million volt protons.
Then the ship thudded to the chatter of the Garnell rifles.
* * * * *
Tensely the men watched the planet ahead, white, yet barely visible in
the weak sunlight so far out. It was swimming slowly nearer as the tiny
ship gathered speed.
Kendall cast a glance over his detector-instruments. The radio network
was undisturbed, the magnetic and electric fields recognized only the
slight disturbances occasioned by the planet itself. There was nothing,
noth--
Five hundred miles away, a gigantic ship came into instantaneous being.
Simultaneously, and instantaneously, the various detector systems howled
their warnings. Kendall gasped as the thing appeared on his view screen,
with the scale-lines below. The scale must be cock-eyed. They said the
ship was fifteen hundred feet in diameter, and two thousand long!
"Retreat," ordered Kendall, "at maximum acceleration."
Talbot was already acting. The gyroscopes hummed in their castings, and
the motors creaked. The T-247 spun on her axis, and abruptly the
acceleration built up as the ion-rockets began to shudder. A faint smell
of "heat" began to creep out of the converter. Immense "weight" built
up, and pressed the men into their specially designed seats--
The gigantic ship across the way turned slowly, and seemed to stare at
the T-247. Then it darted toward them at incredible speed till the poor
little T-247 seemed to be standing still, as sailors say. The stranger
was so gigantic now, the screens could not show all of him.
"God, Buck--he's going to take us!"
Simultaneously, the T-247 rolled, and from her broke every possible
stream of destruction. The ion-rocket flames swirled abruptly toward
her, the proton-guns whined their song of death in their housings, and
the heavy pounding shudder of the Garnell guns racked the ship.
Strangely, Kendall suddenly noticed, there was a stillness in the ship.
The guns and the rays were still going--but the little human sounds
seemed abruptly gone.
"Talbot--Garnet--" Only silence answered him. Cole looked across at him
in sudden white-faced amazement.
"They're gone--" gasped Cole.
Kendall stood paralyzed for thirty seconds. Then suddenly he seemed to
come to life. "Neutrons! Neutrons--and water tanks! Old Nichols was
right--" He turned to his friend. "Cole--the tender--quick." He darted a
glance at the screen. The giant ship still lay alongside. A wash of ions
was curling around her, splitting, and passing on. The pinprick
explosions of the Garnell shells dotted space around her--but never on
her.
Cole was already racing for the tender lock. In an instant Kendall piled
in after him. The tiny ship, scarcely ten feet long, was powered for
flights of only two hours acceleration, and had oxygen for but
twenty-four hours for six men, seventy-two hours for two men--maybe. The
heavy door was slammed shut behind them, as Cole seated himself at the
panel. He depressed a lever, and a sudden smooth push shot them away
from the T-247.
"DON'T!" called Kendall sharply as Cole reached for the ion-rocket
control. "Douse those lights!" The ship was dark in dark space. The
lighted hull of the T-247 drifted away from the little tender--further
and further till the giant ship on the far side became visible.
"Not a light--not a sign of fields in operation." Kendall said,
unconsciously speaking softly. "This thing is so tiny, that it may
escape their observation in the fields of the T-247 and Pluto down
there. It's our only hope."
"What happened? How in the name of the planets did they kill those men
without a sound, without a flash, and without even warning us, or
injuring us?"
"Neutrons--don't you see?"
"Frankly, I don't. I'm no scientist--merely a technician. Neutrons
aren't used in any process I've run across."
"Well, remember they're uncharged, tiny things. Small as protons, but
without electric field. The result is they pass right through an
ordinary atom without being stopped unless they make a direct hit.
Tungsten, while it has a beautifully high melting point, is mostly open
space, and a neutron just sails right through it, or any heavy atom.
Light atoms stop neutrons better--there's less open space in 'em.
Hydrogen is best. Well--a man is made up mostly of light elements, and a
man stops those neutrons--it isn't surprising it killed those other
fellows invisibly, and without a sound."
"You mean they bathed that ship in neutrons?"
"Shot it full of 'em. Just like our proton guns, only sending neutrons."
"Well, why weren't we killed too?"
"'Water stops neutrons,' I said. Figure it out."
"The rocket-water tanks--all around us! Great masses of water--" gasped
Cole. "That saved us?"
"Right. I wonder if they've spotted us."
* * * * *
The stranger ship was moving slowly in relation to the T-247. Suddenly
the motion changed, the stranger spun--and a giant lock appeared in her
side, opened. The T-247 began to move, floated more and more rapidly
straight for the lock. Her various weapons had stopped operating now,
the hoppers of the Garnell guns exhausted, the charge of the
accumulators aboard the ship down so low the proton guns had died out.
"Lord--they're taking the whole ship!"
"Say--Cole, is that any ship you ever heard of before? _I don't think
that's just a pirate!_"
"Not a pirate--what then?"
"How'd he get inside our detector screens so fast? Watch--he'll either
leave, or come after us--" The T-247 had settled inside the lock now,
and the great metal door closed after it. The whole patrol ship had been
swallowed by a giant. Kendall was sketching swiftly on a notebook,
watching the vast ship closely, putting down a record of its lines, and
formation. He glanced up at it, and then down for a few more lines, and
up at it--
The stranger ship abruptly dwindled. It dwindled with incredible speed,
rushing off along the line of sight at an impossible velocity, and
abruptly clicking out of sight, like an image on a movie-film that has
been cut, and repaired after the scene that showed the final
disappearance.
"Cole--Cole--did you get that? Did you see--do you understand what
happened?" Kendall was excitedly shouting now.
"He missed us," Cole sighed. "It's a wonder--hanging out here in space,
with the protector of the T-247's fields gone."
"No, no, you asteroid--that's not it. _He went off faster than light
itself!_"
"Eh--what? Faster than _light_? That can't be done--"
"He did it, I know he did. That's how he got inside our screens. He came
inside faster than the warning message could relay back the information.
Didn't you see him accelerate to an impossible speed in an impossible
time? Didn't you see how he just vanished as he exceeded the speed of
light, and stopped reflecting it? _That ship was no ship of this solar
system!_"
"Where did he come from then?"
"God only knows, but it's a long, long way off."
II
The IP-M-122 picked them up. The M-122 got out there two days later, in
response to the calls the T-247 had sent out. As soon as she got within
ten million miles of the little tender, she began getting Cole's
signals, and within twelve hours had reached the tiny thing, located it,
and picked it up.
Captain Jim Warren was in command, one of the old school commanders of
the IP. He listened to Kendall's report, listened to Cole's tale--and
radioed back a report of his own. Space pirates in a large ship had
attacked the T-247, he said, and carried it away. He advised a close
watch. On Pluto, his investigations disclosed nothing more than the fact
that three mines had been raided, all platinum supplies taken, and the
records and machinery removed.
* * * * *
The M-122 was a fifty-man patrol cruiser, and Warren felt sure he could
handle the menace alone, and hung around for over two weeks looking for
it. He saw nothing, and no further reports came of attack. Again and
again, Kendall tried to convince him this ship he was hunting was no
mere space pirate, and again and again Warren grunted, and went on his
way. He would not send in any report Kendall made out, because to do so
would add his endorsement to that report. He would not take Kendall
back, though that was well within his authority.
In fact, it was a full month before Kendall again set foot on any of the
Minor Planets, and then it was Mars, the base of the M-122. Kendall and
Cole took passage immediately on an IP supply ship, and landed in New
York six days later. At once, Kendall headed for Commander McLaurin's
office. Buck Kendall, lieutenant of the IP, found he would have to make
regular application to see McLaurin through a dozen intermediate
officers.
By this time, Kendall was savagely determined to see McLaurin himself,
and see him in the least possible time. Cole, too, was beginning to
believe in Kendall's assertion of the stranger ship's extra-systemic
origin. As yet neither could understand the strange actions of the
machine, its attack on the Pluto mines, and the capture and theft of a
patrol ship.
"There is," said Kendall angrily, "just one way to see McLaurin and see
him quick. And, by God, I'm going to. Will you resign with me, Cole?
I'll see him within a week then, I'll bet."
For a minute, Cole hesitated. Then he shook hands with his friends.
"Today!" And that day it was. They resigned, together. Immediately, Buck
Kendall got the machinery in motion for an interview, working now from
the outside, pulling the strings with the weight of a hundred million
dollar fortune. Even the IP officers had to pay a bit of attention when
Bernard Kendall, multi-millionaire began talking and demanding things.
Within a week, Kendall _did_ see McLaurin.
At that time, McLaurin was fifty-three years old, his crisp hair still
black as space, with scarcely a touch of the gray that appears in his
more recent photographs. He stood six feet tall, a broad-shouldered,
powerful man, his face grave with lines of intelligence and character.
There was also a permanent narrowing of the eyes, from years under the
blazing sun of space. But most of all, while those years in space had
narrowed and set his eyes, they had not narrowed and set his mind. An
infinitely finer character than old Jim Warren, his experience in space
had taught him always to expect the unexpected, to understand the
incomprehensible as being part of the unknown and incalculable
properties of space and the worlds that swam in it. Besides the fine
technical education he had started with, he had acquired a liberal
education in mankind. When Buck Kendall, straight and powerful, came
into his office with Cole, he recognized in him a character that would
drive steadily and straight for its goal. Also, he recognized behind the
millionaire that had succeeded in pulling wires enough to see him, the
scientist who had had more than one paper published "in an amateur way."
"Dr. Bernard Kendall?" he asked, rising.
"Yes, sir. Late Buck Kendall, lieutenant of the IP. I quit and got Cole
here to quit with me, so we could see you."
"Unusual tactics. I've had several men join up to get an interview with
me." McLaurin smiled.
"Yes, I can imagine that, but we had to see you in a hurry. A hidebound
old rapscallion by the name of Jim Warren picked us up out by Pluto,
floating around in a six-man tender. We made some reports to him, but he
wouldn't believe, and he wouldn't send them through--so we had to send
ourselves through. Sir, this system is about to be attacked by some
extra-systemic race. The IP-T-247 was so attacked, her crew killed off,
and the ship itself carried away."
"I got the report Captain Jim Warren sent through, stating it was a gang
of space pirates. Now what makes you believe otherwise?"
"That ship that attacked us, attacked with a neutron gun, a gun that
shot neutrons through the hull of our ship as easily as protons pass
through open space. Those neutrons killed off four of the crew, and
spared us only because we happened to be behind the water tanks. Masses
of hydrogen will stop neutrons, so we lived, and escaped in the tender.
The little tender, lightless, escaped their observation, and we were
picked up. Now, when the 247 had been picked up, and locked into their
ship, that ship started accelerating. It accelerated so fast along my
line of sight that it just dwindled, and--vanished. It didn't vanish in
distance, it vanished _because it exceeded the speed of light_."
"Isn't that impossible?"
"Not at all. It can be done--if you can find some way of escaping from
this space to do it. Now if you could cut across through a higher
dimension, your _projection_ in this dimension might easily exceed the
speed of light. For instance, if I could cut directly through the Earth,
at a speed of one thousand miles an hour, my projection on the surface
would go twelve thousand miles while I was going eight. Similar, if you
could cut _through_ the four dimensional space instead of following its
surface, you'd attain a speed greater than light."
"Might it not still be a space pirate? That's a lot easier to believe,
even allowing your statement that he exceeded the speed of light."
"If you invented a neutron gun which could kill through tungsten walls
without injuring anything within, a system of accelerating a ship that
didn't affect the inhabitants of that ship, and a means of exceeding the
speed of light, all within a few months of each other, would you become
a pirate? I wouldn't, and I don't think any one else would. A pirate is
a man who seeks adventure and relief from work. Given a means of
exceeding the speed of light, I'd get all the adventure I wanted
investigating other planets. If I didn't have a cent before, I'd have
relief from work by selling it for a few hundred millions--and I'd sell
it mighty easily too, for an invention like that is worth an
incalculable sum. Tie to that the value of compensated acceleration, and
no man's going to turn pirate. He can make more millions selling his
inventions than he can make thousands turning pirate with them. So who'd
turn pirate?"
"Right." McLaurin nodded. "I see your point. Now before I'd accept your
statements _in re_ the 'speed of light' thing, I'd want opinions from
some IP physicists."
"Then let's have a conference, because something's got to be done soon.
I don't know why we haven't heard further from that fellow."
"Privately--we have," McLaurin said in a slightly worried tone. "He was
detected by the instruments of every IP observatory I suspect. We got
the reports but didn't know what to make of them. They indicated so many
funny things, they were sent in as accidental misreadings of the
instruments. But since _all_ the observatories reported them, similar
misreadings, at about the same times, that is with variations of only a
few hours, we thought something must have been up. The only thing was
the phenomena were reported progressively from Pluto to Neptune, clear
across the solar system, in a definite progression, but at a velocity of
crossing that didn't tie in with any conceivable force. They crossed
faster than the velocity of light. That ship must have spent about half
an hour off each planet before passing on to the next. And, accepting
your faster-than-light explanation, we can understand it."
"Then I think you have proof."
"If we have, what would you do about it?"
"Get to work on those 'misreadings' of the instruments for one thing,
and for a second, and more important, line every IP ship with paraffin
blocks six inches thick."
"Paraffin--why?"
"The easiest form of hydrogen to get. You can't use solid hydrogen,
because that melts too easily. Water can be turned into steam too
easily, and requires more work. Paraffin is a solid that's largely
hydrogen. That's what they've always used on neutrons since they
discovered them. Confine your paraffin between tungsten walls, and
you'll stop the secondary protons as well as the neutrons."
"Hmmm--I suppose so. How about seeing those physicists?"
"I'd like to see them today, sir. The sooner you get started on this
work, the better it will be for the IP."
"Having seen me, will you join up in the IP again?" asked McLaurin.
"No, sir, I don't think I will. I have another field you know, in which
I may be more useful. Cole here's a better technician than fighter--and
a darned good fighter, too--and I think that an inexperienced
space-captain is a lot less useful than a second-rate physicist at work
in a laboratory. If we hope to get anywhere, or for that matter, I
suspect, stay anywhere, we'll have to do a lot of research pretty
promptly."
"What's your explanation of that ship?"
"One of two things: an inventor of some other system trying out his
latest toy, or an expedition sent out by a planetary government for
exploration. I favor the latter for two reasons: that ship was _big_. No
inventor would build a thing that size, requiring a crew of several
hundred men to try out his invention. A government would build just
about that if they wanted to send out an expedition. If it were an
inventor, he'd be interested in meeting other people, to see what they
had in the way of science, and probably he'd want to do it in a
peaceable way. That fellow wasn't interested in peace, by any means. So
I think it's a government ship, and an unfriendly government. They sent
that ship out either for scientific research, for trade research and
exploration, or for acquisitive exploration. If they were out for
scientific research, they'd proceed as would the inventor, to establish
friendly communication. If they were out for trade, the same would
apply. If they were out for acquisitive exploration, they'd investigate
the planets, the sun, the people, only to the extent of learning how
best to overcome them. They'd want to get a sample of our people, and a
sample of our weapons. They'd want samples of our machinery, our
literature and our technology. That's exactly what that ship got.
"Somebody, somewhere out there in space, either doesn't like their home,
or wants more home. They've been out looking for one. I'll bet they sent
out hundreds of expeditions to thousands of nearby stars, gradually
going further and further, seeking a planetary system. This is probably
the one and only one they found. It's a good one too. It has planets at
all temperatures, of all sizes. It is a fairly compact one, it has a
stable sun that will last far longer than any race can hope to."
"Hmm--how can there be good and bad planetary systems?" asked McLaurin.
"I'd never thought of that."
Kendall laughed. "Mighty easy. How'd you like to live on a planet of a
Cepheid Variable? Pleasant situation, with the radiation flaring up and
down. How'd you like to live on a planet of Antares? That blasted sun
is so big, to have a comfortable planet you'd have to be at least ten
billion miles out. Then if you had an interplanetary commerce, you'd
have to struggle with orbits tens of billions of miles across instead of
mere millions. Further, you'd have a sun so blasted big, it would take
an impossible amount of energy to lift the ship up from one planet to
another. If your trip was, say, twenty billions of miles to the next
planet, you'd be fighting a gravity as bad as the solar gravity at Earth
here all the way--no decline with a little distance like that."
"H-m-m-m--quite true. Then I should say that Mira would take the prize.
It's a red giant, and it's an irregular variable. The sunlight there
would be as unstable as the weather in New England. It's almost as big
as Antares, and it won't hold still. Now that _would_ make a bad
planetary system."
"It would!" Kendall laughed. But as we know--he laughed too soon, and he
shouldn't have used the conditional. He should have said, "It does!"
III
Gresth Gkae, Commander of Expeditionary Force 93, of the Planet Sthor,
was returning homeward with joyful mind. In the lock of his great ship,
lay the T-247. In her cargo holds lay various items of machinery, mining
supplies, foods, and records. And in her log books lay the records of
many readings on the nine larger planets of a highly satisfactory
planetary system.
Gresth Gkae had spent no less than three ultra-wearing years going from
one sun to another in a definitely mapped out section of space. He had
investigated only eleven stars in that time, eleven stars, progressively
further from the titanic red-flaming sun he knew as "the" sun. He knew
it as "the" sun, and had several other appellations for it. Mira was
so-named by Earthmen because it was indeed a "wonder" star, in Latin,
mirare means "to wonder." Irregularly, and for no apparent reason it
would change its rate of radiation. So far as those inhabitants of Sthor
and her sister world Asthor knew, there was no reason. It just did it.
Perhaps with malicious intent to be annoying. If so, it was
exceptionally successful. Sthor and Asthor experienced, periodically, a
young ice age. When Mira decided to take a rest, Sthor and Asthor froze
up, from the poles most of the way to the equators. Then Mira would
stretch herself a little, move about restlessly and Sthor and Asthor
would become uninhabitably hot, anywhere within twenty degrees of the
equator.
Those Sthorian people had evolved in a way that made the conditions
endurable for savage or uncivilized people, but when a scientific
civilization with a well-ordered mode of existence tried to establish
itself, Mira was all sorts of a nuisance.
Gresth Gkae was a peculiar individual to human ways of thinking. He
stood some seven feet tall, on his strange, double-kneed legs and his
four toed feet. His body was covered with little, short feather-like
things that moved now with a volition of their own. They were moving
very slowly and regularly. The space-ship was heated to a comfortable
temperature, and the little fans were helping to cool Gresth Gkae. Had
it been cold, every little feather would have lain down close against
its neighbors, forming an admirable, wind-proof and cold-proof blanket.
Nature, on Sthor, had original ideas of arrangement too. Sthorians
possessed two eyes--one directly above the other, in the center of their
faces. The face was so long, and narrow, it resembled a blunt hatchet,
with the two eyes on the edge. To counter-balance this vertical
arrangement of the eyes, the nostrils had been separated some four
inches, with one on each of the sloping cheeks. His ears were little
pink-flesh cups on short, muscular stems. His mouth was narrow, and
small, but armed with quite solid teeth adapted to his diet, a diet
consisting of almost anything any creature had ever considered edible.
Like most successful forms of intelligent life, Gresth Gkae was
omnivorous. An intelligent form of life is necessarily adaptable, and
adaptation meant being able to eat what was at hand.
One of his eyes, the upper one, was fully twice the size of the lower
one. This was his telescopic eye. The lower, or microscopic eye was
adapted to work for which a human being would have required a low power
microscope, the upper eye possessed a more normal power of vision,
_plus_ considerable telescopic powers.
Gresth Gkae was using it now to look ahead in the blank of space to
where gigantic Mira appeared. On his screens now, Mira appeared deep
violet, for he was approaching at a speed greater than that of light,
and even this projected light of Mira was badly distorted.
"The distance is half a light-year now, sir," reported the navigation
officer.
"Reduce the speed, then, to normal velocity for these ranges. What
reserve of fuel have we?"
"Less than one thousand pounds. We will barely be able to stop. We were
too free in the use of our weapons, I fear," replied the Chief
Technician.
"Well, what would you? We needed those things in our reports. Besides,
we could extract fuel from that ore we took on at Planet Nine of Phahlo.
It is merely that I wish speed in the return."
"As we all do. How soon do you believe the Council will proceed against
the new system?"
"It will be fully a year, I fear. They must gather the expeditions
together, and re-equip the ships. It will be a long time before all will
have come in."
"Could they not send fast ships after them to recall them?"
"Could they have traced us as we wove our way from Thart to Karst to
Raloork to Phahlo? It would be impossible."
* * * * *
Steadily the great ship had been boring on her way. Mira had been a disc
for nearly two days, gigantic, two-hundred-and-fifty-million-mile Mira
took a great deal of dwarfing by distance to lose her disc. Even at the
Twin Planets, eight thousand two hundred and fifty millions of miles
out, Mira covered half the sky, it seemed, red and angry. Sometimes,
though, to the disgust of the Sthorians it was just red-faced and lazy.
Then Sthor froze.
"Grih is in a descendant stage," said the navigation officer presently.
"Sthor will be cold when we arrive."
"It will warm quickly enough with our news!" Gresth laughed. "A
system--a delightful system--discovered. A system of many close-grouped
planets. Why think--from one side of that system to the other is less of
a distance than from Ansthat, our first planet's orbit, to Insthor's
orbit! That sun, as we know, is steady and warm. All will be well, when
we have eliminated that rather peculiar race. Odd, that they should, in
some ways, be so nearly like us! Nearly Sthorian in build. I would not
have expected it. Though they did have some amazing peculiarities!
Imagine--two eyes just alike, and in a horizontal row. And that flat
face. They looked as though they had suffered some accident that smashed
the front of the face in. And also the peculiar beak-like projection.
Why should a race ever develop so amazing a projection in so peculiar
and exposed a position? It sticks out inviting attack and injury. Right
in the middle of the face. And to make it worse, there is the
air-channel, and the only air channel. Why, one minor injury to the
throat would be certain to damage that passage beyond repair, and bring
death. Yet such relatively unimportant things as ears, and eyes are
doubled. Surely you would expect that so important a member as the
air-passage would be doubled for safety.
"Those strange, awkward arms and legs were what puzzled me. I have been
attempting to manipulate myself as they must be forced to, and I cannot
see how delicate or accurate manual manipulation would be possible with
those rigid, inflexible arms. In some ways I feel they must have had
clever minds to overcome so great a handicap to constructive work. But I
suppose single joints in the arms become as natural to them as our own
more mobile two.
"I wonder if life in any intelligent form wouldn't develop somewhat
similar formations, though. Think, in all parts of Sthor, before men
became civilized and developed communication, even so much as twenty
thousand years ago, our records show that seats and chairs were much as
they are today, and much as they are, in all places among all groups.
Then too, the eye has developed in many different species, and always
reached much the same structure. When a thing is intended and developed
to serve a given purpose, no matter who develops it, or where or how, is
it not apt to have similar shapes and parts? A chair must have legs, and
a seat and arm-rests and a back. You may vary their nature and their
shape, but not widely, and they must be there. An eye must, anywhere,
have a sensitive retina, an adjustable lens, and an adjustable device
for controlling the entrance of light. Similarly there are certain
functions that the body of an intelligent creature must serve which
naturally tend to make intelligent creatures similar. He must have a
tool--the hand--"
"Yes, yes--I see your point. It must be so, for surely these creatures
out there are strange enough in other ways."
"But tell me, have you calculated when we shall land?"
"In twelve hours, thirty-three minutes, sir."
Eleven hours later, the expedition ship had slowed to a normal
space-speed. On her left hung the giant globe of Asthor, rotating
slowly, moving slowly in her orbit. Directly ahead, Sthor loomed even
greater. Tiny Teelan, the thousand-mile diameter moon of the Insthor
system shone dull red in the reflected light of gigantic Mira. Mira
herself was gigantic, red and menacing across eight and a quarter
billions of miles of space.
One hundred thousand miles apart, the twin worlds Sthor and Asthor
rotated about their common center of gravity, eternally facing each
other. Ten million miles from their common center of gravity, Teelan
rotated in a vast orbit.
Sthor and Asthor were capped at each pole now by gigantic white icecaps.
Mira was sulking, and as a consequence the planets were freezing.
The expedition ship sank slowly toward Sthor. A swarm of smaller craft
had flown up at its approach to meet it. A gaily-colored small ship
marked the official greeting-ship. Gresth had withheld his news
purposely. Now suddenly he began broadcasting it from the powerful
transmitter on his ship. As the words came through on a thousand sets,
all the little ships began to whirl, dance and break out into glowing,
sparkling lights. On Sthor and Asthor even commotions began to be
visible. A new planetary system had been found-- They could move! Their
overflowing populations could be spread out!
The whole Insthor system went mad with delight as the great
Expeditionary Ship settled downward.
IV
There was a glint of humor in Buck Kendall's eyes as he passed the sheet
over to McLaurin. Commander McLaurin looked down the columns with
twinkling eyes.
"'Petition to establish the Lunar Mining Bank,'" he read. "What a bank!
Officers: President, General James Logan, late of the IP;
Vice-president, Colonel Warren Gerardhi, also late of the IP; Staff,
consists of 90% ex-IP men, and a few scattered accountants. Designed by
the well-known designer of IP stations, Colonel Richard Murray."
Commander McLaurin looked up at Kendall with a broad grin. "And you
actually got Interplanetary Life to give you a mortgage on the
structure?"
"Why not? It'll cut cost fifty-eight millions, with its twelve-foot
tungsten-beryllium walls and the heavy defense weapons against those
terrible pirates. You know we must defend our property."
"With the thing you're setting up out there on Luna, you could more
readily wipe out the IP than anything else I know of. Any new defense
ideas?"
"Plenty. Did you get any further appropriations from the IP
Appropriations Board?"
McLaurin looked sour. "No. The dear taxpayers might object, and those
thickheaded, clogged rockets on the Board can't see your data on the
Stranger. They gave me just ten millions, and that only because you
demonstrated you could shoot every living thing out of the latest IP
cruiser with that neutron gun of yours. By the way, they may kick when I
don't install more than a few of those."
"Let 'em. You can stall for a few months. You'll need that money more
for other purposes. You've installed that paraffin lining?"
"Yes--I got a report on that of 'finished' last week. How have you made
out?"
Buck Kendall's face fell. "Not so hot. Devin's been the biggest help--he
did most of the work on that neutron gun really--"
"After," McLaurin interrupted, "you told him how."
"--but we're pretty well stuck now, it seems. You'll be off duty
tomorrow evening, can't you drop around to the lab? We're going to try
out a new system for releasing atomic energy."
"Isn't that a pretty faint hope? We've been trying to get it for three
centuries now, and haven't yet. What chance at it within a year or
so?--which is the time you allow yourself before the Stranger returns."
"It is, I'll admit that. But there's another factor, not to be
forgotten. The data we got from correlating those 'misreadings' from the
various IP posts mean a lot. We are working on an entirely different
trail now. You come on out, and you can see our new apparatus. They are
working on tremendous voltages, and hoping to smash the thing by a
brutal bombardment of terrific voltage. We're trying, thanks to the
results of those instruments, to get results with small, terrifically
intense fields."
"How do you know that's their general system?"
"They left traces on the records of the post instruments. These records
show such intensities as we never got. They have atomic energy,
necessarily, and they might have had material energy, actual destruction
of matter, but apparently, from the field readings it's the former. To
be able to make those tremendous hops, light-years in length, they
needed a real store of energy. They have accumulators, of course, but I
don't think they could store enough power by the system they use to do
it."
"Well, how's your trick 'bank' out on Luna, despite its twelve-foot
walls, going to stand an atomic explosion?"
"More protective devices to come is our only hope. I'm working on three
trails: atomic energy, some type of magnetic shield that will stop any
moving material particle, and their faster-than-light thing. Also, that
fortress--I mean, of course, bank--is going to have a lot of lead-lined
rooms."
"I wish I could use the remaining money the Board gave me to lead-line a
lot of those IP ships," said McLaurin wistfully. "Can't you make a
gamma-ray bomb of some sort?"
"Not without their atomic energy release. With it, of course, it's easy
to flood a region with rays. It'll be a million times worse than radium
'C,' which is bad enough."
"Well, I'll send through this petition for armaments. They'll pass it
all right, I think. They may get some kicks from old Jacob Ezra Stubbs.
Jacob Ezra doesn't believe in anything war-like. I wish they'd find some
way to keep him off of the Arms Petition Board. He might just as well
stay home and let 'em vote his ticket uniformly 'nay.'" Buck Kendall
left with a laugh.
* * * * *
Buck Kendall had his troubles though. When he had reached Earth again,
he found that his properties totaled one hundred and three million
dollars, roughly. One doesn't sell properties of that magnitude, one
borrows against them. But to all intents and purposes, Buck Kendall
owned two half-completed ship's hulls in the Baldwin Spaceship Yards, a
great deal of massive metal work on its way to Luna, and contracts for
some very extensive work on a "bank." Beyond that, about eleven million
was left.
A large portion of the money had been invested in a laboratory, the like
of which the world had never seen. It was devoted exclusively to
physics, and principally the physics of destruction. Dr. Paul Devin was
the Director, Cole was in charge of the technical work, and Buck Kendall
was free to do all the work he thought needed doing.
Returned to his laboratory, he looked sourly at the bench on which seven
mechanicians were working. The ninth successive experiment on the
release of atomic energy had failed. The tenth was in process of
construction. A heavy pure tungsten dome, three feet in diameter, three
inches thick, was being lowered over a clear insulum dome, a foot
smaller. Inside, the real apparatus was arranged around the little pool
of mercury. From it, two massive tungsten-copper alloy conductors led
through the insulum housing, and outside. These, so Kendall had hoped,
would surge with the power of broken atoms, but he was beginning to
believe rather bitterly, they would never do so.
Buck went on to his offices, and the main calculator room. There were
ten calculator tables here, two of them in operation now.
"Hello, Devin. Getting on?"
"No," said Devin bitterly, "I'm getting off. Look at these results." He
brought over a sheaf of graphs, with explanatory tables attached.
Rapidly Buck ran through them with him. Most of them were graphs of
functions of light, considered as a wave in these experiments.
"H-m-m-m--not very encouraging. Looks like you've got the field--but it
just snaps shut on itself and won't work. The lack of volume makes it
break down, if you establish it, and makes it impossible to establish in
the first place without the energy of matter. Not so hot. That's
certainly cock-eyed somewhere."
"I'm not. The math may be."
"Well"--Kendall grinned--"it amounts to the same thing. The point is,
light doesn't. Let's run over that theory again. Light is not only
magnetic; but electric. Somehow it transforms electric fields cyclically
into magnetic fields and back again. Now what we want to do is to
transform an electric into a magnetic field and have it stay there.
That's the first step. The second thing, is to have the lines of
magnetic force you develop, lie down like a sheath around the ship,
instead of standing out like the hairs on an angry cat, the way they
want to. That means turning them ninety degrees, and turning an electric
into a magnetic field means turning the space-strain ninety degrees.
Light evidently forms a magnetic field whose lines of force reach along
its direction of motion, so that's your starting point."
"Yes, and _that_," growled Devin, "seems to be the finishing point.
Quite definitely and clearly, the graph looped down to zero. In other
words, the field closed in on itself, and destroyed itself."
"Light doesn't vanish."
"I'll make you all the lights you want."
"I simply mean there must be something that will stop it."
"Certainly. Transform it back to electric field before it gets a chance
to close in, then repeat the process--the way light does."
"That wouldn't make such a good magnetic shield. Every time that field
started pulsing out through the walls of the ship it would generate
heat. We want a permanent field that will stay on the job out there. I
wonder if you couldn't make a conductor device that would open that
field out--some special type of oscillating field that would keep it
open."
"H-m-m-m--that's an angle I might try. Any suggestions?"
Kendall had suggestions, and rapidly he outlined a development that
appeared from some of the earlier mathematics on light, and might be
what they wanted.
* * * * *
Kendall, however, had problems of his own to work on. The question of
atomic energy he was leaving alone, till the present experiment either
succeeded, or, as he rather suspected, failed as had its predecessors.
His present problem was to develop more fully some interesting lines of
research he had run across in investigating mathematically the trick of
turning electric to magnetic fields and then turning them back again. It
might be that along this line he would find the answer to the speed
greater than that of light. At any rate, he was interested.
He worked the rest of that day, and most of the next on that line--till
he ran it into the ground with a pair of equations that ended with the
expression: dx.dv=h/(4[pi]m). Then Kendall looked at them for a long
moment, then he sighed gently and threw them into a file cabinet.
Heisenberg's Uncertainty. He'd reduced the thing to a form that simply
told him it was beyond the limits of certainty and he ran it into the
normal, natural uncertainty inevitable in Nature.
Anyway he had real work to do now. The machine was about ready for his
attention. The mechanicians had finished putting it in shape for
demonstration and trial. He himself would have to test it over the rest
of the afternoon and arrange for power and so forth.
By evening, when Commander McLaurin called around with some of the other
investors in Kendall's "bank" on Luna, the thing was already started,
warming up. The fields were being fed and the various scientists of the
group were watching with interest. Power was flowing in already at a
rate of nearly one hundred thousand horsepower per minute, thanks to a
special line given them by New York Power (a Kendall property). At ten
o'clock they were beginning to expect the reaction to start. By this
time the fields weren't gaining in intensity very rapidly, a maximum
intensity had been reached that should, they felt, break the atoms soon.
At eleven-thirty, through the little view window, Buck Kendall saw
something that made him cry out in amazement. The mercury metal in the
receiver, behind its layers of screening was beginning to glow, with a
dull reddish light, and little solidifications were appearing in it!
Eagerly the men looked, as the solidifications spread slowly, like
crystals growing in an evaporating solution.
Twelve o'clock came and went, and one o'clock and two o'clock. Still the
slow crystallization went on. Buck Kendall was casting furtive glances
at the kilowatt-hour meter. It stood at a figure that represented
twenty-seven thousand dollars' worth of power. Long since the power rate
had been increased to the maximum available, as the power plant's normal
load reduced as the morning hours came. Surely, this time something
would start, but Buck had two worries. If all the enormous amount of
energy they had poured in there decided to release itself at once--
And at any rate, Buck saw they'd never dare to let a generator stop,
once it was started!
The men were a tense group around the machine at three-fifteen A.M.
There remained only a tiny, dancing globule of silvery mercury
skittering around on the sharp, needle-like crystals of the dull red
metal that had resulted. Slowly that skittering drop was shrinking--
Three twenty-two and a half A.M. saw the last fraction of it vanish.
Tensely the men stared into the machine--backing off slowly--watching
the meters on the board. At nearly eighty thousand volts the power had
been fed into it.
The power continued to flow, and a growing halo of intense violet light
appeared suddenly on those red, needle-like crystals, a swiftly
expanding halo--
Without a sound, without the slightest disturbance, the halo vanished,
and softly, gently, the needle-like crystals relapsed, melted away, and
a dull pool of metallic mercury rested in the receiver.
At eighty thousand volts, power was flowing in--
And it didn't even sparkle.
V
The apparatus of the magnetic shield had been completed two days later,
and set up in Buck's own laboratory. On the bench was the powerful, but
small, little projector of the straight magnetic field, simply a
specially designed accumulator, a super-condenser, and the peculiar
apparatus Devin had designed to distort the electric field through
ninety degrees to a magnetic field. Behind this was a curious,
paraboloid projector made up of hundreds of tiny, carefully orientated
coils. This was Buck's own contribution. They were ready for the tests.
"I would invite McLaurin in to see this," said Kendall looking at them,
and then across the room bitterly toward the alleged atomic power
apparatus on the opposite bench. "I think it will work. But after
_that_--" He stared, glaring, at the heavy tungsten dome with its heavy
tungsten contacts, across which the flame of released atomic energy was
supposed to have leapt. "That was probably the flattest flop any
experiment ever flopped."
"Well--it didn't blow up. That's one comfort," suggested Devin.
"I wish it had. Then at least it would have shown some response. The
only response shown, actually, was shown on the power meter. It damn
near wore out the bearings turning so fast."
"Personally, I prefer the lack of action." Devin laughed. "Have you got
that circuit hooked up?"
"Right," sighed Kendall, turning back to the work in hand. "Is Douglass
in on this?"
"Yes--in the next room. He'll let us know when he's ready. He's setting
up those instruments."
Douglass, a young junior physicist, late of the IP Physics Department,
stuck his head in the door and announced his instruments were all set
up.
"Keep an eye on them. They'll move somehow, at any rate. This thing
couldn't go as flat as that atom-buster of mine."
Carefully Kendall made a few last-minute adjustments on the limiting
relays, and took up his position at the power board. Devin took his
place near the apparatus, with another series of instruments, similar to
those Douglass was now watching in the next room, some thirty feet away,
through the two-inch metal wall. "Ready," called Kendall.
The switch shot home. Instantly Kendall, Devin, and all the men in the
building jumped some six feet from their former positions. A monstrous
roar of sound crashed out in that laboratory that thundered from one
wall to the other, and bellowed in a Titan's fury. It thundered and
growled, it bellowed and howled, the walls shook with the march and
counter-march of crashing waves of sound.
And a ten-foot wavering flame of blue-white, bellying electric fire
shuddered up to the ceiling from the contact points of the alleged
atomic generator. The heat, pouring out from the flashing, roaring arc
sent prickles of aching burns over Kendall's skin. For ten seconds he
stood in utter, paralyzed surprise as his flop of flops bellowed its
anger at his disdain. Then he leapt to the power board and shut off the
roaring thing, by cutting the switch that had started it.
"Spirits of Space! Did _that_ come to life!"
"_Atomic Energy!_" Devin cried.
"Atomic energy, hell. That's my thirty thousand dollars' worth of power
breaking loose again," chortled Kendall. "We missed the atomic energy,
but, sweet boy, what an accumulator we stubbed our toes on! I wondered
where in blazes all that power went to. That's the answer. I'll bet I
can tell you right now what happened. We built that mercury up to a new
level, and that transitional stage was the red, crystalline metal. When
it reached the higher stage, it was temporarily stable--but that
projector over there that we designed for the purpose of holding open
electric and magnetic fields just opened the door and let all that power
right out again."
"But why isn't it atomic energy? How do you know that no more than your
power that you put in is coming out?" demanded Devin.
"The arc, man, the arc. That was a high-current, and low-voltage arc.
Couldn't you tell by the sound that no great voltage--as atomic voltages
go--was smashing across there? If we were getting atomic voltage--and
power--there'd have been a different tone to it, high and shriller.
"Now, did you take any readings?"
"What do you think, man? I'm human. Do you think I got any readings with
that thing bellowing and shrieking in my ears, and burning my skin with
ultra-violet? It itches now."
Kendall laughed. "You know what to do for an itch. Now, I'm going to
make a bet. We had those points separated for a half-million volts
discharge, but there was a dust-cover thrown over them just now. That,
you notice, is missing. I'll bet that served as a starter lead for the
main arc. Now I'm going to start that projector thing again, and move
the points there through about six inches, and that thing probably won't
start itself."
* * * * *
Most of the laboratory staff had collected at the doorway, looking in at
the white-hot tungsten discharge points, and the now silent "atomic
engine." Kendall turned to them and said: "The flop picked itself up.
You go on back, we seem to be all in one piece yet. Douglass, you didn't
get any readings, did you?"
Sheepishly, Douglass grinned at him. "Eh--er--no--but I tore my pants.
The magnetic field grabbed me and I jumped. They had some steel buttons,
and a lot of steel keys--they're kinda' hard to keep on now."
The laboratory staff broke into a roar of laughter, as Douglass, holding
up his trousers with both hands was beheld.
"I guess the field worked," he said.
"I guess maybe it did," adjudged Kendall solemnly. "We have some rope
here if you need it--"
Douglass returned to his post.
Swiftly, Kendall altered the atomic distortion storage apparatus, and
returned to the power-board. "Ready?"
"Check."
Kendall shoved home the switch. The storage device was silent. Only a
slight feeling of strain made itself felt, and the sudden noisy hum of a
small transformer nearby. "She works, Buck!" Devin called. "The readings
check almost exactly."
"All good then. Now I want to get to that atomic thing. We can let that
slide for a little bit--I'll answer it."
The telephone had rung noisily. "Kendall Labs--Kendall speaking."
"This is Superintendent Foster, of the New York Power, Mr. Kendall. We
have some trouble just now that we think your operations may be
responsible for. The sub-station at North Beaumont blew all the fuses,
and threw the breakers at the main station. The men out there said the
transformers began howling--"
"Right you are--I'm afraid I did do that. I had no idea that it would
reach so far. How far is that from my place here?"
"It's about a thousand yards, according to the survey maps."
"Thanks--and I'll be careful about it. Any damage, I am responsible for?
All okay?"
"Yes, sir, Mr. Kendall."
Kendall hung up. "We stirred up a lot more dust
than we expected, Devin. Now let's start seeing if we can keep track of
it. Douglass, how did your readings show?"
"I took them at the ten stations, and here they are. The stations are
two feet apart."
"H-m-m--.5--.55--.6--.7--20--198--5950--6010--6012--5920. Very, very
nice--only the darned thing's got an arm as long as the law. Your
readings were about .2, Devin?"
"That's right."
"Then these little readings are just leakage. What's our normal
intensity here?"
"About .19. Just a very small fraction less than the readings."
"Perfect--we have what amounts to a hollow shell of magnetic force--we
can move inside, and you can move outside--far enough. But you can't get
a conductor or a magnetic field through it." He put the readings on the
bench, and looked at the apparatus across the room. "Now I want to start
right on that other. Douglass, you move that magnetostat apparatus out
of the way, and leave just the 'can-opener' of ours--the projector. I'm
pretty sure that's what does the deed. Devin, see if you can hunt up
some electrostatic voltmeters with a range in the neighborhood of--I
think it'll be about eighty thousand."
* * * * *
Rapidly, Douglass was dismounting the apparatus, as Devin started for
the stock room. Kendall started making some new connections,
reconnecting the apparatus they had intended using on the "atomic
engine," largely high-capacity resistances. He seemed to perform this
work mechanically, his mind definitely on something else. Suddenly he
stopped, and looked carefully into the receiver of the machine. The
metal in it was silvery, liquid, and here and there a floating crystal
of the dull red metal. Slowly a smile spread across his face. He turned
to Douglass.
"Douglass--ah, you're through. Get on the trail of MacBride, and get him
and his crew to work making half a dozen smaller things like this. Tell
'em they can leave off the tungsten shield. I want different metals in
the receiver of each. Use--hmmm--sodium--copper--magnesium--aluminium,
iron and chromium. Got it?"
"Yes, sir." He left, just as Devin returned with a large electrostatic
voltmeter.
"I'd like," said he, "to know how you know the voltage will range around
eighty thousand."
"K-ring excitation potential for mercury. I'm willing to bet that thing
simply shoved the whole electron system of the mercury out a notch--that
it simply _hasn't_ any K-ring of electrons now. I'm trying some other
metals. Douglass is going to have MacBride make up half a dozen more
machines. Machines--they need a name. This--ah--this is an 'atostor.'
MacBride's going to make up half a dozen of 'em, and try half a dozen
metals. I'm almost certain that's not mercury in there now, at all. It's
probably element 99 or something like it."
"It looks like mercury--"
"Certainly. So would 99. Following the periodic table, 99 would probably
have an even lower melting point than mercury, be silvery, dense and
heavy--and perhaps slightly radioactive. The series under the B family
of Group II is Magnesium, Zinc, Cadmium, Mercury--and 99. The melting
point is going down all the way, and they're all silvery metals. I'm
going to try copper, and I fully expect it to turn silvery--in fact, to
become silver."
"Then let's see." Swiftly they hooked up the apparatus, realigned the
projector, and again Kendall took his place at the power-board. As he
closed the switch, on no-load, the electrostatic voltmeter flopped over
instantly, and steadied at just over 80,000 volts.
"I hate to say 'I told you so,'" said Kendall. "But let's hook in a
load. Try it on about 100 amps first."
Devin began cutting in load. The resistors began heating up swiftly as
more and more current flowed through them. By not so much as by a
vibration of the voltmeter needle, did the apparatus betray any strain
as the load mounted swiftly. 100--200--500--1000 amperes. Still, that
needle held steady. Finally, with a drain of ten thousand amperes, all
the equipment available could handle, the needle was steady as a rock,
though the tremendous load of 800,000,000 watts was cut in and out.
That, to atoms, atoms by the nonillions, was no appreciable load at all.
There was _no_ internal resistance whatever. The perfect accumulator
had certainly been discovered.
"I'll have to call McLaurin--" Kendall hurried away with a broad, broad
smile.

"Hello, Tom?"
The telephone rattled in a peeved sort of way. "Yes, it is. What now?
And when am I going to see you in a social sort of way again?"
"Not for a long, long time; I'm busy. I'm busy right now as a matter of
fact. I'm calling up the vice-president of Faragaut Interplanetary
Lines, and I want to place an order."
"Why bother me? We have clerks, you know, for that sort of thing,"
suggested Faragaut in a pained voice.
"Tom, do you know how much I'm worth now?"
"Not much," replied Faragaut promptly. "What of it? I hear, as a matter
of fact that you're worth even less in a business way. They're talking
quite a lot down this way about an alleged bank you're setting up on
Luna. I hear it's got more protective devices, and armor than any IP
station in the System, that you even had it designed by an IP designer,
and have a gang of Colonels and Generals in charge. I also hear that
you've succeeded in getting rid of money at about one million dollars a
day--just slightly shy of that."
"You overestimate me, my friend. Much of that is merely contracted for.
Actually it'll take me nearly nine months to get rid of it. And by that
time I'll have more. Anyway, I think I have something like ten million
left. And remember that way back in the twentieth century some old
fellow beat my record. Armour, I think it was, lost a million dollars a
day for a couple of months running.
"Anyway, what I called you up for was to say I'd like to order five
hundred thousand tons of mercury, for delivery as soon as possible."
"What! Oh, say, I thought you were going in for business." Faragaut gave
a slight laugh of relief.
"Tom, I am. I mean exactly what I say. I want
five--hundred--thousand--_tons_ of metallic mercury, and just as soon as
you can get it."
"Man, there isn't that much in the system."
"I know it. Get all there is on the market for me, and contract to take
all the 'Jupiter Heavy-Metals' can turn out. You send those orders
through, and clean out the market completely. Somebody's about to pay
for the work I've been doing, and boy, they're going to pay through the
nose. After you've got that order launched, and don't make a christening
party of the launching either, why just drop out here, and I'll show you
why the value of mercury is going so high you won't be able to follow it
in a space ship."
"The cost of that," said Faragaut, seriously now, "will be
about--fifty-three million at the market price. You'd have to put up
twenty-six cash, and I don't believe you've got it."
Buck laughed. "Tom, loan me a dozen million, will you? You send that
order through, and then come see what I've got. I've got a break, too!
Mercury's the best metal for this use--and it'll stop gamma rays too!"
"So it will--but for the love of the system, what of it?"
"Come and see--tonight. Will you send that order through?"
"I will, Buck. I hope you're right. Cash is tight now, and I'll probably
have to put up nearer twenty million, when all that buying goes through.
How long will it be tied up in that deal, do you think?"
"Not over three weeks. And I'll guarantee you three hundred percent--if
you'll stay in with me after you start. Otherwise--I don't think making
this money would be fair just now."
"I'll be out to see you in about two hours, Buck. Where are you? At the
estate?" asked Faragaut seriously.
"In my lab out there. Thanks, Tom."
McLaurin was there when Tom Faragaut arrived. And General Logan, and
Colonel Gerardhi. There was a restrained air of gratefulness about all
of them that Tom Faragaut couldn't quite understand. He had been looking
up Buck Kendall's famous bank, and more and more he had begun to wonder
just what was up. The list of stockholders had read like a list of IP
heroes and executives. The staff had been a list of IP men with a
slender sprinkling of accountants. And the sixty-million dollar
structure was to be a bank without advertising of any sort! Usually such
a venture is planned and published months in advance. This had sprung up
suddenly, with a strange quietness.
Almost silently, Buck Kendall led the way to the laboratory. A small
metal tank was supported in a peculiar piece of apparatus, and from it
led a small platinum pipe to a domed apparatus made largely of insulum.
A little pool of mercury, with small red crystals floating in it rested
in a shallow hollow surrounded by heavy conductors.
"That's it, Tom. I wanted to show you first what we have, and why I
wanted all that mercury. Within three weeks, every man, woman and child
in the system will be clamoring for mercury metal. That's the perfect
accumulator." Quickly he demonstrated the machine, charging it, and then
discharging it. It was better than 99.95% efficient on the charge, and
was 100% efficient on the discharge.
"Physically, any metal will do. Technically, mercury is best for a
number of reasons. It's a liquid. I can, and do it in this, charge a
certain quantity, and then move it up to the storage tank. Charge
another pool, and move it up. In discharge, I can let a stream flow in
continuously if I required a steady, terrific drain of power without
interruption. If I wanted it for more normal service, I'd discharge a
pool, drain it, refill the receiver, and discharge a second pool. Thus,
mercury is the metal to use.
"Do you see why I wanted all that metal?"
"I do, Buck--Lord, I do," gasped Faragaut. "That is the perfect power
supply."
"No, confound it, it isn't. It's a secondary source. It isn't primary.
We're just as limited in the _supply_ of power as ever--only we have
increased our distribution of power. Lord knows, we're going to need a
power _supply_ badly enough before long--" Buck relapsed into moody
silence.
"What," asked Faragaut, looking around him, "does that mean?"
It was McLaurin who told him of the stranger ship, and Kendall's
interpretation of its meaning. Slowly Faragaut grasped the meaning
behind Buck's strange actions of the past months.
"The Lunar Bank," he said slowly, half to himself. "Staffed by trained
IP men, experts in expert destruction. Buck, you said something about
the profits of this venture. What did you mean?"
Buck smiled. "We're going to stick up IP to the extent necessary to pay
for that fort--er--bank--on Luna. We'll also boost the price so that
we'll make enough to pay for those ships I'm having made. The public
will pay for that."
"I see. And we aren't to stick the price too high, and just make money?"
"That's the general idea."
"The IP Appropriations Board won't give you what you need, Commander,
for real improvements on the IP ships?"
"They won't believe Kendall. Therefore they won't."
"What did you mean about gamma rays, Buck?"
"Mercury will stop them and the Commander here intends to have the
refitted ships built so that the engine room and control room are one,
and completely surrounded by the mercury tanks. The men will be
protected against the gamma rays."
"Won't the rays affect the power stored in the mercury--perhaps release
it?"
"We tried it out, of course, and while we can't get the intensities we
expect, and can't really make any measurements of the gamma-ray energy
impinging on the mercury--it seems to absorb, and store that energy!"
"What's next on the program, Buck?"
"Finish those ships I have building. And I want to do some more
development work. The Stranger will return within six months now, I
believe. It will take all that time, and more for real refitting of the
IP ships."
"How about more forts--or banks, whichever you want to call them. Mars
isn't protected."
"Mars is abandoned," replied General Logan seriously. "We haven't any
too much to protect old Earth, and she must come first. Mars will, of
course, be protected as best the IP ships can. But--we're expecting
defeat. This isn't a case of glorious victory. It will be a case of hard
won survival. We don't know anything about the enemy--except that they
are capable of interstellar flights, and have atomic energy. They are
evidently far ahead of us. Our battle is to survive till we learn how to
conquer. For a time, at least, the Strangers will have possession of
most of the planets of the system. We do not think they will be able to
reach Earth, because Commander McLaurin here will withdraw his ships to
Earth to protect the planet--and the great 'Lunar Bank' will display its
true character."
VII
Faragaut looked unsympathetically at Buck Kendall, as he stood glaring
perplexedly at the apparatus he had been working on.
"What's the matter, Buck, won't she perk?"
"No, damn it, and it should."
"That," pointed out Faragaut, "is just what you think. Nature thinks
otherwise. We generally have to abide by her opinions. What is it--or
what is it meant to be?"
"Perfect reflector."
"Make a nice mirror. What else, and how come?"
"A mirror is just what I want. I want something that will reflect _all_
the radiation that falls on it. No metal will, even in its range of
maximum reflectivity. Aluminum goes pretty high, silver, on some ranges,
a bit higher. But none of them reaches 99%. I want a perfect reflector
that I can put behind a source of wild, radiant energy so I can focus
it, and put it where it will do the most good."
"Ninety-nine percent. Sounds pretty good. That's better efficiency than
most anything else we have, isn't it?"
"No, it isn't. The accumulator is 100% efficient on the discharge, and a
good transformer, even before that, ran as high as 99.8 sometimes. They
had to. If you have a transformer handling 1,000,000 horsepower, and
it's even 1% inefficient, you have a heat loss of nearly 10,000
horsepower to handle. I want to use this as a destructive weapon, and if
I hand the other fellow energy in distressing amounts, it's even worse
at my end, because no matter how perfect a beam I work out, there will
still be some spread. I can make it mighty tight though, if I make my
surface a perfect parabola. But if I send a million horse, I have to
handle it, and a ship can't stand several hundred thousand horsepower
roaming around loose as heat, let alone the weapon itself. The thing
will be worse to me than to him.
"I figured there was something worth investigating in those fields we
developed on our magnetic shield work. They had to do, you know, with
light, and radiant energy. There must be some reason why a metal
reflects. Further, though we can't get down to the basic root of matter,
the atom, yet, we can play around just about as we please with molecules
and molecular forces. But it is molecular force that determines whether
light and radiant energy of that caliber shall be reflected or
transmitted. Take aluminum as an example. In the metallic molecule
state, the metal will reflect pretty well. But volatilize it, and it
becomes transparent. All gases are transparent, all metals reflective.
Then the secret of perfect reflection lies at a molecular level in the
organization of matter, and is within our reach. Well--this thing was
supposed to make that piece of silver reflective. I missed it that
time." He sighed. "I suppose I'll have to try again."
"I should think you'd use tungsten for that. If you do have a slight
leak, that would handle the heat."
"No, it would hold it. Silver is a better conductor of heat. But the
darned thing won't work."
"Your other scheme has." Faragaut laughed. "I came out principally for
some signatures. IP wants one hundred thousand tons of mercury. I've
sold most of mine already in the open market. You want to sell?"
"Certainly. And I told you my price."
"I know," sighed Faragaut. "It seems a shame though. Those IP board men
would pay higher. And they're so damn tight it seems a crime not to make
'em pay up when they have to."
"The IP will need the money worse elsewhere. Where do I--oh, here?"
"Right. I'll be out again this evening. The regular group will be here?"
Kendall nodded as he signed in triplicate.
* * * * *
That evening, Buck had found the trouble in his apparatus, for as he
well knew, the theory was right, only the practical apparatus needed
changing. Before the group composed of Faragaut, McLaurin and the
members of Kendall's "bank," he demonstrated it.
It was merely a small, model apparatus, with a mirror of space-strained
silver that was an absolutely perfect reflector. The mirror had been
ground out of a block of silver one foot deep, by four inches square,
carefully annealed, and the work had all been done in a cooling bath.
The result was a mirror that was so nearly a perfect paraboloid that the
beam held sharp and absolutely tight for the half-mile range they tested
it on. At the projector it was three and one-half inches in diameter. At
the target, it was three and fifty-two one hundredths inches in
diameter.
"Well, you've got the mirror, what are you going to reflect with it
now?" asked McLaurin. "The greatest problem is getting a radiant source,
isn't it? You can't get a temperature above about ten thousand degrees,
and maintain it very long, can you?"
"Why not?" Kendall smiled.
"It'll volatilize and leave the scene of action, won't it?"
"What if it's a gaseous source already?"
"What? Just a gas-flame? That won't give you the point source you need.
You're using just a spotlight here, with a Moregan Point-light. That
won't give you energy, and if you use a gas-flame, the spread will be so
great, that no matter how perfectly you figure your mirror, it won't
beam."
"The answer is easy. Not an ordinary gas-flame--a very extra-special
kind of gas-flame. Know anything about Renwright's ionization-work?"
"Renwright--he's an IP man isn't he?"
"Right. He's developed a system, which, thanks to the power we can get
in that atostor, will sextuply ionize oxygen gas. Now: what does that
mean?"
"Spirits of space! Concentrated essence of energy!"
"Right. And in preparation, Cole here had one made up for me. That--and
something else. We'll just hook it up--"
With Devin's aid, Kendall attached the second apparatus, a larger device
into which the silver block with its mirror surface fitted. With the
uttermost care, the two physicists lined it up. Two projectors pointed
toward each other at an angle, the base angles of a triangle, whose apex
was the center of the mirror. On very low power, a soft, glowing violet
light filtered out through the opening of the one, and a slight green
light came from the other. But where the two streams met, an intense,
violet glare built up. The center of action was not at the focus, and
slowly this was lined up, till a sharp, violet beam of light reached out
across the open yard to the target set up.
Buck Kendall cut off the power, and slowly got into position. "Now. Keep
out from in front of that thing. Put on these glasses--and watch out."
Heavy, thick-lensed orange-brown goggles were passed out, and Kendall
took his place. Before him, a thick window of the same glass had been
arranged, so that he might see uninterruptedly the controls at hand, and
yet watch unblinded, the action of the beam.
Dully the mirror-force relay clicked. A hazy glow ran over the silver
block, and died. Then--simultaneously the power was thrown from two
small, compact atostors into the twin projectors. Instantly--a titanic
eruption of light almost invisibly violet, spurted out in a solid,
compact stream. With a roar and crash, it battered its way through the
thick air, and crashed into the heavy target plate. A stream of flame
and scintillating sparks erupted from the armor plate--and died as
Kendall cut the beam. A white-hot area a foot across leaked down the
face of the metal.
"That," said Faragaut gently, removing his goggles. "That's not a
spotlight, and it's not exactly a gas-flame. But I still don't know what
that blue-hot needle of destruction is. Just what do you call that tame
stellar furnace of yours?"
"Not so far off, Tom," said Kendall happily, "except that even S Doradus
is cold compared to that. That sends almost pure ultra-violet
light--which, by the way, it is almost impossible to reflect
successfully, and represents a temperature to be expressed not in
thousands of degrees, nor yet in tens of thousands. I calculated the
temperature would be about 750,000 degrees. What is happening is that a
stream of low-voltage electrons--cathode rays--in great quantity are
meeting great quantities of sextuply ionized oxygen. That means that a
nucleus used to having two electrons in the K-ring, and six in the next,
has had that outer six knocked off, and then has been hurled violently
into free air.
"All by themselves, those sextuply ionized oxygen atoms would have a
good bit to say, but they don't really begin to talk till they start
roaring for those electrons I'm feeding them. At the meeting point, they
grab up all they can get--probably about five--before the competition
and the fierce release of energy drives them out, part-satisfied. I lose
a little energy there, but not a real fraction. It's the howl they put
up for the first four that counts. The electron-feed is necessary,
because otherwise they'd smash on and ruin that mirror. They work
practically in a perfect vacuum. That beam smashes the air out of the
way. Of course, in space it would work better."
"How could it?" asked Faragaut, faintly.
"Kendall," asked McLaurin, "can we install that in the IP ships?"
"You can start." Kendall shrugged. "There isn't a lot of apparatus. I'm
going to install them in my ships, and in the--bank. I suspect--we
haven't a lot of time left."
"How near ready are those ships?"
"About. That's all I can say. They've been torn up a bit for
installation of the atostor apparatus. Now they'll have to be changed
again."
"Anything more coming?"
Buck smiled slowly. He turned directly to McLaurin and replied:
"Yes--the Strangers. As to developments--I can't tell, naturally. But if
they do, it will be something entirely unexpected now. You see, given
one new discovery, a half-dozen will follow immediately from it. When we
announced that atostor, look what happened. Renwright must have thought
it was God's gift to suffering physicists. He stuck some oxygen in the
thing, added some of his own stuff--and behold. The magnetic apparatus
gave us directly the shield, and indirectly this mirror. Now, I seem to
have reached the end for the time. I'm still trying to get that
space-release for high speed--speed greater than light, that is. So
far," he added bitterly, "all I've gotten as an answer is a single
expression that simply means practical zero--Heisenberg's Uncertainty
Expression."
"I'm uncertain as to your meaning"--McLaurin smiled--"but I take it
that's nothing new."
"No. Nearly four centuries old--twentieth century physics. I'll have to
try some other line of attack, I guess, but that did seem so darned
right. It just sounded right. Something ought to happen--and it just
keeps saying 'nothing more except the natural uncertainty of nature.'"
"Try it out, your math might be wrong somewhere."
Kendall laughed. "If it was--I'd hate to try it out. If it wasn't I'd
have no reason to. And there's plenty of other work to do. For one
thing, getting that apparatus in production. The IP board won't like
me." Kendall smiled.
"They don't," replied McLaurin. "They're getting more and more and more
worried--but they've got to keep the IP fleet in such condition that it
can at least catch an up-to-date freighter."
* * * * *
Gresth Gkae looked back at Sthor rapidly dropping behind, and across at
her sister world, Asthor, circling a bare 100,000 miles away. Behind his
great interstellar cruiser came a long line of similar ships. Each was
loaded now not with instruments and pure scientists, but with weapons,
fuel and warriors. Colonists too, came in the last ships. One hundred
and fifty giant ships. All the wealth of Sthor and Asthor had been
concentrated in producing those great machines. Every one represented
nearly the equivalent of thirty million Earth-dollars. Four and a half
billions of dollars for mere materials.
Gresth Gkae had the honor of lead position, for he had discovered the
planets and their stable, though tiny, sun. Still, Gresth Gkae knew his
own giant Mira was a super-giant sun--and a curse and a menace to any
rational society. Our yellow-white sun (to his eyes, an almost invisible
color, similar to our blue) was small, but stable, and warm enough.
In half an hour, all the ships were in space, and at a given signal, at
ten-second intervals, they sprang into the superspeed, faster than
light. For an instant, giant Mira ran and seemed distorted, as though
seen through a porthole covered with running water, then steadied,
curiously distorted. Faster than light they raced across the galaxy.
Even in their super-fast ships, nearly three and a half weeks passed
before the sun they sought, singled itself from the star-field as an
extra bright point. Two days more, and the sun was within planetary
distance. They came at an angle to the plane of the ecliptic, but they
leveled down to it now, and slanted toward giant Jupiter and Jovian
worlds. Ten worlds, in one sweep, it was--four habitable worlds. The
nine satellites would be converted into forts at once, nine
space-sweeping forts guarding the approaches to the planet. Gresth Gkae
had made a fairly good search of the worlds, and knew that Earth was the
main home of civilization in this system. Mars was second, and Venus
third. But Jupiter offered the greatest possibilities for quick
settlement, a base from which they could more easily operate, a base for
fuels, for the heavy elements they would need--
Fifteen million miles from Jupiter they slowed below the speed of
light--and the IP stations observed them. Instantly, according to
instructions issued by Commander McLaurin, a fleet of ten of the
tiniest, fastest scouts darted out. As soon as possible, a group of
three heavy cruisers, armed with all the inventions that had been
discovered, the atostor power system, perfectly conducting power leads,
the terrible UV ray, started out.
The scouts got there first. Cameras were grinding steadily, with long
range telescopic lenses, delicate instruments probed and felt and caught
their fingers in the fields of the giant fleet.
At ten-second intervals, giant ships popped into being, and glided
smoothly toward Jupiter.
Then the cruisers arrived. They halted at a respectful distance, and
waited. The Miran ships plowed on undisturbed. Simultaneously, from the
three leaders, terrific neutron rays shot out. The paraffin block walls
stopped those--and the cruisers started to explain their feelings on the
subject. They were the IP-J-37, 39, and 42. The 37 turned up the full
power of the UV ray. The terrific beam of ultra-violet energy struck the
second Miran ship, and the spot it touched exploded into incandescence,
burned white-hot--and puffed out abruptly as the air pressure within
blew the molten metal away.
The Mirans were startled. This was not the type of thing Gresth Gkae had
warned them of. Gresth Gkae himself frowned as the sudden roar of the
machines of his ship rose in the metal walls. A stream of ten-inch
atomic bombs shrieked out of their tubes, fully glowing green things
floated out more slowly, and immediately waxed brilliant. Gamma ray
bombs--but they could be guarded against--
The three Solarian cruisers were washed in such frightful flame as they
had never imagined. Streams of atomic bombs were exploding soundlessly,
ineffectively in space, not thirty feet from them as they felt the
sudden resistance of the magnetic shields. Hopefully, the 39 probed with
her neutron gun. Nothing happened save that several gamma ray bombs went
off explosively, and all the atomic bombs in its path exploded at once.
Gresth Gkae knew what that meant. Neutron beam guns. Then this race was
more intelligent than he had believed. They had not had them before. Had
he perhaps given them too much warning and information?
There was a sudden, deeper note in the thrumming roar of the great
ship. Eagerly Gresth Gkae watched--and sighed in relief. The nearer of
the three enemy ships was crumbling to dust. Now the other two were
beginning to become blurred of outline. They were fleeing--but oh, so
slowly. Easily the greater ship chased them down, till only floating
dust, and a few small pieces of--
Gresth Gkae shrieked in pain, and horror. The destroyed ships had fought
in dying. All space seemed to blossom out with a terrible light, a light
that wrapped around them, and burned into him, and through him. His eyes
were dark and burning lumps in his head, his flesh seemed crawling,
stinging--he was being flayed alive--in shrieking agony he crumpled to
the floor.
Hospital attachés came to him, and injected drugs. Slowly torturing
consciousness left him. The doctors began working over his horribly
burned body, shuddering inwardly as the protective, feather-like
covering of his skin loosened, and dropped from his body. Tenderly they
lowered him into a bath of chemicals--
"The terrible light which caused so much damage to our men," reported a
physicist, "was analyzed, and found to have some extraordinary lines. It
was largely mercury-vapor spectrum, but the spectrum of mercury-atoms in
an impossibly strained condition. I would suggest that great care be
used hereafter, and all men be equipped with protective masks when
observations are needed. This sun is very rich in the infra-X-rays and
ultra-visible light. The explosion of light, we witnessed, was dangerous
in its consisting almost wholly of very short and hard infra-X-rays."
The physicist had a special term for what we know as ultra-violet light.
To him, blue was ultra-violet, and exceedingly dangerous to
red-sensitive eyes. To him, our ultra-violet was a long X-ray, and was
designated by a special term. And to him--the explosion of the atostor
reservoirs was a terrible and mystifying calamity.
To the men in the five tiny scout-ships, it was also a surprise, and a
painful one. Even space-hardened humans were burned by the terrifically
hard ultra-violet from the explosion. But they got some hint of what it
had meant to the Mirans from the confusion that resulted in the fleet.
Several of the nearer ships spun, twisted, and went erratically off
their courses. All seemed uncontrolled momentarily.
The five scouts, following orders, darted instantly toward the Lunar
Bank. Why, they did not know. But those were orders. They were to land
there.
The reason was that, faster than any Solarian ship, radio signals had
reached McLaurin, and he, and most of the staff of the IP service had
been moved to the Lunar Bank. Buck Kendall had extended an invitation in
this "unexpected emergency." It so happened that Buck Kendall's
invitation got there before any description of the Strangers, or their
actions had arrived. The staff was somewhat puzzled as to how this
happened--
And now for the satellites of great Jupiter.
One hundred and fifty giant interstellar cruisers advanced on Callisto.
They didn't pause to investigate the mines and scattered farms of the
satellite, but ten great ships settled, and a horde of warriors began
pouring out.
One hundred and forty ships reached Ganymede. One hundred and thirty
sailed on. One hundred and thirty ships reached Europa--and they sailed
on hurriedly, one hundred and twenty-nine of them. Gresth Gkae did not
know it then, but the fleet had lost its first ship. The IP station on
Europa had spoken back.
They sailed in, a mighty armada, and the first dropped through Europa's
thin, frozen atmosphere. They spotted the dome of the station, and a
neutron ray lashed out at it. On the other, undefended worlds, this had
been effective. Here--it was answered by ten five-foot UV rays. Further,
these men had learned something from the destruction of the cruisers,
and ten torpedoes had been unloaded, reloaded with atostor mercury, and
sent out bravely.
Easily the Mirans wiped out the first torpedo--
Shrieking, the Miran pilots clawed their way from the controls as the
fearful flood of ultra-violet light struck their unaccustomed skins.
Others too felt that burning flood.
The second torpedo they caught and deflected on a beam of
alternating-current magnetism that repelled it. It did not come nearer
than half a mile to the ship. The third they turned their deflecting
beam on--and something went strangely wrong with the beam. It pulled
that torpedo toward the ship with a sickening acceleration--and the
torpedo exploded in that frightful violet flame.
* * * * *
Five-foot diameter UV beams are nothing to play with. The Mirans were
dodging these now as they loosed atomic bombs, only to see them exploded
harmlessly by neutron guns, or caught in the magnetic screen. Gamma ray
bombs were as useless. Again the beam of disintegrating force was turned
on--
The present opponent was not a ship. It was an IP defense station,
equipped with everything Solarian science knew, and the dome was an
eight-foot wall of tungsten-beryllium. The eight feet of solid,
ultra-resistant alloy drank up that crumbling beam, and liked it. The
wall did not fail. The men inside the fort jerked and quivered as the
strange beam, a small, small fraction of it, penetrated the eight feet
of outer wall, the six feet or so of intervening walls, and the mercury
atostor reserves.
"Concentrate all those UV beams on one spot, and see if you can blast a
hole in him before he shakes it loose," ordered the ray technician.
"He'll wiggle if you start off with the beam. Train your sights on the
nose of that first ship--when you're ready, call out."
"Ready--ready--" Ten men replied. "Fire!" roared the technician. Ten
titanic swords of pure ultra-violet energy, energy that practically no
unconditioned metal will reflect to more than fifty per cent, emerged.
There was a single spot of intense incandescence for a single hundredth
of a second--and then the energy was burning its way through the inner,
thinner skins with such rapidity that they sputtered and flickered like
a broken televisor.
One hundred and twenty-nine ships retreated hastily for conference,
leaving a gutted, wrecked hull, broken by its fall, on Europa.
Triumphantly, the Europa IP station hurled out its radio message of the
first encounter between a fort and the Miran forces.
Most important of all, it sent a great deal of badly wanted information
regarding the Miran weapons. Particularly interesting was the fact that
it had withstood the impact of that disintegrating ray.
VIII
Grimly Buck Kendall looked at the reports. McLaurin stood beside him,
Devin sat across the table from him. "What do you make of it, Buck?"
asked the Commander.
"That we have just one island of resistance left on the Jovian worlds.
And that will, I fear, vanish. They haven't finished with their arsenal
by any means."
"But what was it, man, what was it that ruined those ships?"
"Vibration. Somehow--Lord only knows how it's done--they can project
electric fields. These projected fields are oscillated, and they are
tuned in with some parts of the ship. I suspect they are crystals of the
metals. If they can start a vibration in the crystals of the
metal--that's fatigue, metal fatigue enormously speeded. You know how a
quartz crystal oscillator in a radio-control apparatus will break, if
you work it on a very heavy load at the peak? They simply smash the
crystals of metal in the same way. Only they project their field."
"Then our toughest metals are useless? Can't something tough, rather
than hard, like copper or even silver for instance, stand it?"
"Calcium metal's the toughest going--and even that would break under the
beating those ships give it. The only way to withstand it is to have
such a mass of metal that the oscillations are damped out. But--"
The set tuned in on the IP station on Europa was speaking again. "The
ships are returning. There are one hundred and twenty-nine by accurate
count. Jorgsen reports that telescopic observation of the dead on the
fallen cruiser show them to be a _completely un-human race_! They are
of mottled coloring, predominately grayish brown. The ships are
returning. They have divided into ten groups, nine groups of two each,
and a main body of the rest of the fleet. The group of eighteen is
descending within range, and we are focusing our beams on them--"
Out by Europa, ten great UV beams were stabbing angrily toward ten great
interstellar ships. The metal of the hulls glowed brilliant, and
distorted slowly as the thick walls softened under the heat, and the air
behind pressed against it. Grimly the ten ships came on. Torpedoes were
being launched, and exploded, and now they had no effect, for the Mirans
within were protected.
The eighteen grouped ships separated, and arranged themselves in a
circle around the fort. Suddenly one staggered as a great puff of gas
shot out through the thin atmosphere of Europa to flare brilliantly in
the lash of the stabbing UV beam. Instantly the ship righted itself, and
labored upward. Another dropped to take its place--
And the great walls of the IP fort suddenly groaned and started in their
welded joints. The faint, whispering rustle of the crumbling beam was
murmuring through the station. Engineers shouted suddenly as meters
leapt the length of their scales, and the needles clicked softly on the
stop pins. A thin rustle came from the atostors grouped in the great
power room. "Spirits of Space--a revolving magnetic field!" roared the
Chief Technician. "They're making this whole blasted station a squirrel
cage!"
The mighty walls of eight-foot metal shuddered and trembled. The UV
beams lashed out from the fort in quivering arcs now, they did not hold
their aim steady, and the magnetic shield that protected them from
atomic bombs was working and straining wildly. Eighteen great ships
quivered and tugged outside there now, straining with all their power to
remain in the same spot, as they passed on from one to another the
magnetic impulses that were now creating a titanic magnetic vortex about
the fort.
"The atostors will be exhausted in another fifteen minutes," the Chief
Technician roared into his transmitter. "Can the signals get through
those fields, Commander?"
"No, Mac. They've been stopped, Sparks tells me. We're here--and let's
hope we stay. What's happening?"
"They've got a revolving magnetic field out there that would spin a
minor planet. The whole blasted fort is acting like the squirrel cage in
an induction motor! They've made us the armature in a five hundred
million horsepower electric motor."
"They can't tear this place loose, can they?"
"I don't know--it was never--" The Chief stopped. Outside a terrific
roar and crash had built up. White darts of flame leapt a thousand feet
into the air, hurling terrific masses of shattered rock and soil.
"I was going to say," the Chief went on, "this place wasn't designed for
that sort of a strain. Our own magnetic field is supporting us now,
preventing their magnetic field from getting its teeth on metal. When
the strain comes--well, they're cutting loose our foundation with atomic
bombs!"
Five UV beams were combined on one interstellar ship. Instantly the
great machine retreated, and another dropped in to take its place while
the magnetic field spun on, uninterruptedly.
"Can they keep that up long?"
"God knows--but they have a hundred and more ships to send in when the
power of one gives out, remember."
"What's our reserve now?"
The Chief paused a moment to look at the meters. "Half what it was ten
minutes ago!"
Commander Wallace sent some other orders. Every torpedo tube of the
station suddenly belched forth deadly, fifteen-foot torpedoes, most of
them mud-torpedoes, torpedoes loaded with high explosive in the nose, a
delayed fuse, and a load of soft clinging mud in the rear. The mud would
flow down over the nose and offer a resistance foot-hold for the
explosive which empty space would not. Four hundred and three torpedoes,
equipped with anti-magnetic apparatus darted out. One hundred and four
passed the struggling fields. One found lodgement on a Miran ship, and
crushed in a metal wall, to be stopped by a bulkhead.
The Chief engineer watched his power declining. All ten UV beams were
united in one now, driving a terrible sword of energy that made the
attacked ship skip for safety instantly, yet the beams were all but
useless. For the Miran reserves filled the gap, and the magnetic tornado
continued.
For seventeen long minutes the station resisted the attack. Then the
last of the strained mercury flowed into the receivers, and the vast
power of the atostors was exhausted. Slowly the magnetic fields
declined. The great walls of the station felt the clutching lines of
force--they began to heat and to strain. A low, harsh grinding became
audible over the roar of the atomic bombs. The whole structure trembled,
and jumped slightly. The roar of bombs ceased suddenly, as the station
jerked again, more violently. Then it turned a bit, rolled clumsily.
Abruptly it began to spin violently, more and more rapidly. It started
rolling clumsily across the plateau--
A rain of atomic bombs struck the unprotected metal, and the eighth
breached the walls. The twentieth was the last. There was no longer an
IP station on Europa.
"The difference," said Buck Kendall slowly, when the reports came in
from scout-ships in space that had witnessed the last struggle, "between
an atomic generator and an atomic power-store, or accumulator, is
clearly shown. We haven't an adequate _source_ of power."
McLaurin sighed slowly, and rose to his feet. "What can we do?"
"Thank our lucky stars that Faragaut here, and I, bought up all the
mercury in the system, and had it brought to Earth. We at least have a
supply of materials for the atostors."
"They don't seem to do much good."
"They're the best we've got. All the photocells on Earth and Venus and
Mercury are at present busy storing the sun's power in atostors. I have
two thousand tons of charged mercury in our tanks here in the 'Lunar
Bank.'"
"Much good that will do--they can just pull and pull and pull till it's
all gone. A starfish isn't strong, but he can open the strongest oyster
just because he can pull from now on. You may have a lot of power--but."
"But--we also have those new fifteen-foot UV beams. And one fifteen-foot
UV beam is worth, theoretically, nine five-foot beams, and practically,
a dozen. We have a dozen of them. Remember, this place was designed not
only to protect itself, but Earth, too."
"They can still pull, can't they?"
"They'll stop pulling when they get their fingers burned. In the
meantime, why not use some of those IP ships to bring in a few more
cargoes of charged mercury?"
"They aren't good for much else, are they? I wonder if those fellows
have anything more we don't know?"
"Oh, probably. I'm going to work on that crumbler thing. That's the
first consideration now."
"Why?"
"So we can move a ship. As it is, even those two we built aren't any
good."
"Would they be anyway?"
"Well--I think I might disturb those gentlemen slightly. Remember, they
each have a nose-beam eighteen feet across. Exceedingly unpleasant
customers."
"Score: Strangers; magnetic field, atomic bombs, atomic power, crumbler
ray. Home team; UV beams."
Kendall grinned. "I'd heard you were a pessimistic cuss when battle
started--"
"Pessimistic, hell, I'm merely counting things up."
"McClellan had all the odds on Lee back in the Civil War of the
States--but Lee sent him home faster than he came."
"But Lee lost in the end."
"Why bring that up? I've got work to do." Still smiling, Kendall went to
the laboratory he had built up in the "Lunar Bank." Devin was already
there, calculating. He looked unhappy.
"We can't do anything, as far as I can see. They're using an electric
field all right, and projecting it. I can't see how we can do that."
"Neither can I," agreed Kendall, "so we can't use that weapon. I really
didn't want to anyway. Like the neutron gun which I told Commander
McLaurin would be useless as a weapon, they'd be prepared for it, you
can be sure. All I want to do is fight it, and make their projection
useless."
"Well, we have to know how they project it before we can break up the
projection, don't we?"
"Not at all. They're using an electric field of very high frequency, but
variable frequency. As far as I can see, all we need is a similar
variable electric field of a slightly different frequency to heterodyne
theirs into something quite harmless."
"Oh," said Devin. "We could, couldn't we? But how are you going to do
that?"
"We'll have to learn, that's all."
* * * * *
Buck Kendall started trying to learn. In the meantime, the Mirans were
taking over Jupiter. There were three IP stations on the planet itself,
but they were vastly hindered by the thick, almost ultra-violet-proof
atmosphere of Jupiter. Their rays were weak. And the magnetic fields of
the Mirans were unaffected. Only their atomic bombs were hindered by the
heavier gravity that pulled the rocks back in place faster than the
bombs could throw them out. Still--a few hours of work, and the IP
stations on Jupiter had rolled wildly across the flat plains of the
planet like dented cans, to end in utter destruction.
The Mirans had paid no attention to the fleeing passenger and freighter
ships that left the planet, loaded to the utmost with human cargo, and
absolutely no freight. The IP fleet had to go to their rescue with
oxygen tanks to take care of the extra humans, but nearly three-quarters
of the population of Jupiter, a newly established population, and hence
a readily mobile one, was saved. The others, the Mirans did not bother
with particularly except when they happened to be near where the Mirans
wanted to work. Then they were instantly destroyed by atomic bombing, or
gamma rays.
The Mirans settled almost at once, and began their work of finding on
Jupiter the badly needed atomic fuels. Machines were set up, and work
begun, Mirans laboring under the gravity of the heavy planet. Then,
fifty ships swam up again, reloaded with fuel, and with crews consisting
solely of uninjured warriors, and started for Mars.
Mars was half way between her near conjunction and her maximum
elongation with respect to Jupiter at that time. The Mirans knew their
business though, for they started in on the IP station on Phobos. They
were practiced by this time, and this IP station had only seven
five-foot beams. In half an hour that station fell, and its sister
station on Deimos followed. Three wounded ships returned to Jupiter, and
ten new ships came out. The attack on Mars itself was started.
Mars was a different proposition. There were thirty-two IP stations
here, one of them nearly as powerful as the Lunar Bank station. It was
equipped with four of the huge fifteen-foot beams. And it had fifteen
tons of mercury, more than seven-eighths charged. The Mars Center
Station was located a short ten miles from the Mars Center City, and
under the immediate orders of the IP heads, Mars Center City had been
vacated.
For two days the Mirans hung off Mars, solidifying their positions on
Phobos and Deimos. Then, with sixty-two ships, they attacked. They had
made some very astute observations, and they started on the smaller
stations just beyond the range of the Mars Center Station. Naturally,
near so powerful a center, these stations had never been strong. They
fell rapidly. But they had been counted on by Mars Center as auxiliary
supports. McLaurin had sent very definite orders to Mars Center
forbidding any action on their part, save gathering of power-supplies.
At last the direct attack on Mars Center was launched. For the first
time, the Mirans saw one of the fifteen-foot beams. Mars' atmosphere is
thin, and there is little ozone. The ultra-violet beams were nearly as
effective as in empty space. When the Mirans dropped their ships, a full
thirty of them, into the circle formation, Mars Center answered at once.
All four beams started.
Those fifteen-foot beams, connected directly to huge atostor release
apparatus, delivered a maximum power of two and three-quarter billion
horsepower, each. The first Miran ship struck, sparkled magnificently,
and a terrific cascade of white-hot metal rolled down from its nose. The
great ship nosed down and to the left abruptly, accelerated swiftly--and
crashed with tremendous energy on the plain outside of Mars Center City.
White, unwavering flames licked up suddenly, and made a column five
hundred feet high against the dark sky. Then the wreck exploded with a
violence that left a crater half a mile across.
Three other ships had been struck, and were rapidly retreating. Another
try was made for the ring formation, and four more ships were wounded,
and replaced. The ring did not retreat, but the great magnetic field
started. Atomic and gamma ray bombs started now, flashing sometimes
dangerously close to the station as its magnetic field battled the
rotating field of the ships. The four greater beams, and many smaller
ones were in swift and angry action. Not more than a ten-second exposure
could be endured by any one ship, before it must retreat.
* * * * *
For five minutes the Mirans hung doggedly at their task. Then, wisely,
they retreated. Of the fleet, not more than seven ships remained
untouched. Mars Center Station had held--at what cost only they knew.
Five hundred tons of their mercury had been exhausted in that brief five
minutes. One hundred tons a minute had flowed into and out of the
atostor apparatus. Mars Center radioed for help, when the fleet lifted.
There was one other station on Mars that stood a good chance of
survival, Deenmor Station, with three of the big beams installed, and
apparatus for their fourth was in the station, and being rapidly worked
over. McLaurin did a wise and courageous thing, at which every man on
Mars cursed. He ordered that all IP stations save these two be deserted,
and all mercury fuel reserves be moved to Deenmor and Mars Center.
The Mirans could not land on the North Western section of Mars, nor in
the South Central region. Therefore Mars was not exactly habitable to
Miran ships, because the great beams had been so perfectly figured that
they were effective at a range of nearly twelve hundred miles.
Deenmor station was attacked--but it was a half-hearted attack, for
Mirans were becoming distinctly skittish about fifteen-foot UV beams.
Two badly blistered ships--and the Mirans retreated to Jupiter. But Mira
held Phobos and Deimos. In two weeks, they had set up cannon there, and
proved themselves accurate long-range gunners. Against the feeble
attraction of Deimos, and with Mars' gravity to help them, they began
bombarding the two stations, and anything that attempted to approach
them, with gamma and atomic explosive bombs. Meanwhile they amused
themselves occasionally by planting a gamma-ray bomb in each of Mars'
major cities. They made Mars uninhabitable for Solarians as well as for
Mirans, at least until the deadly slow-action atomic explosives wore
off, or were removed.
Then the Mirans, after a lapse of three weeks while they dug in their
toes on Jupiter, prepared to leap. Earth was the next goal. Miran
scout-ships had been sent out before this--and severely handled by the
concentrated fleets of the IP that hung grimly off Earth and Luna now.
But the scouts had learned one thing. Mirans could never hope to attain
a firm grasp on Earth while terribly armed Luna hung like a Sword of
Damocles over their heads. Further, attack on Earth directly would be
next to impossible, for, thanks to Faragaut's Interplanetary Company,
nearly all the mercury metal in the system was safely lodged on Earth,
and saturated with power. Every major city had been equipped with great
UV apparatus. And neutron guns in plenty waited on small ships just
outside the atmosphere to explode harmlessly any atomic or gamma bombs
Miran ships might attempt to deposit.
An attack on Luna was the first step. But that terrible, gigantic fort
on Luna worried them. Yet while that fort existed, Earth ships were free
to come and go, for Mirans could not afford to stand near. At a distance
of twenty thousand miles, small Miran ships had felt the touch of those
great UV beams.
Finally, a brief test-attack was made, with an entire fleet of one
hundred ships. They drew almost into position, faster than light, faster
than the signaling warnings could send their messages. In position, all
those great ships strained and heaved at the mighty magnetic vortex that
twisted at the field of the fort. Instantly, twelve of the fifteen-foot
UV beams replied. And--two great UV beams of a size the Mirans had never
seen before, beams from the two ships, "S Doradus" and "Cepheid."
The test-attack dissolved as suddenly as it had come. The Mirans
returned to Jupiter, and to the outer planets where they had further
established themselves. Most of the Solar system was theirs. But the
Solarians still held the choicest planets--and kept the Mirans from
using the mild-temperatured Mars.
IX
"They can't take this, at least," sighed McLaurin as they retreated from
Luna.
"I didn't think they could--right away. I'm wondering though if they
haven't something we haven't seen yet. Besides which--give them time,
give them time."
"Well, give us time, too," snapped McLaurin. "How are you coming?"
Buck smiled. "I'm sure I don't know. I have a machine but I haven't the
slightest idea of whether or not it's any good."
"Why not?"
"I can destroy--I hope--but I can't build up their ray. I can't test the
machine because I haven't their ray to test it against."
"What can we do to test it?"
"The only thing I can see is to call for volunteers--and send out a
six-man cruiser. If the ship's too small, they may not destroy it with
the big crumbler rays. If it's too large--and the machine didn't
work--we'd lose too much."
Twelve hours later, the IP men at the Lunar Bank fort were lined up.
McLaurin stepped up on the platform, and addressed the men briefly, told
them what was needed. Six volunteers were selected by a process of
elimination, those who were married, had dependents, officers, and
others were refused. Finally, six men of the IP were chosen, neither
rookies nor veterans, six average men. And one average six-man cruiser,
one hundred and eleven feet long, twenty-two in diameter. It was the
T-208, a sister ship of the T-247, the first ship to be destroyed.
The T-208 started out from Luna, and with full acceleration, sped out
toward Phobos. Slowly she circled the satellite, while distant scouts
kept her under view. Lazily, the Miran patrol on Phobos watched the
T-208, indifferent to her. The T-208 dove suddenly, after five fruitless
circles of the tiny world, and with her four-foot UV beam flaming,
stabbed angrily at a flight of Miran scouts berthed in the very shadow
of a great battle cruiser, one of the interstellar ships stationed here
on Phobos.
Four of the little ships slumped in incandescence. Angrily the terrific
sword of energy slashed at the frail little scouts.
Angrily the Miran interstellar ship shot herself abruptly into action
against this insolent cruiser. The cruiser launched a flight of the
mercury-torpedoes. Flashing, burning, ultra-violet energy flooded the
great ship, harmlessly, for the men were, as usual, protected. The Miran
answered with the neutron beam, atomic and gamma bombs--and the crumbler
ray.
Gently, softly a halo of shimmering-violet luminescence built up about
the T-208. The UV beam continued to flare, wavering slightly in its
aim--then fell way off to one side. The T-208 staggered suddenly,
wandered from her course--whole, but uncontrolled. For the men within
the ship were dead.
Majestically the Miran swung along beside the dead ship, a great
magnetic tow-cable shot out toward it, to shy off at first, then slowly
to be adjusted, and take hold in the magnetic shield of the T-208. The
pilots of the watching scout-ships turned away. They knew what would
happen.
It did. Five--ten--twenty seconds passed. Then the "dead-man" took over
the ship--and the stored power in the atostor tanks blasted in a
terrible flame that shattered the metal hull to molecular fragments. The
interstellar cruiser shuddered, and rolled half over at the blasting
pressure. Leaking seams appeared in her plates.
The scouts raced back to Luna as the Miran settled heavily, and a trifle
clumsily to Phobos. Miran radio-beams were forcing their way out toward
the Miran station on Europa, to be relayed to the headquarters on
Jupiter, just as Solarian radio beams were thrusting through space
toward Luna. Said the Miran messages: "Their ships no longer crumble."
Said the Solarian messages: "The ships no longer crumble--but the men
die."
* * * * *
His deep eyes burning tensely, Buck Kendall heard the messages coming
in, and rose slowly from his seat to pace the floor. "I think I know
why," he said at last. "I should have thought. For that too can be
prevented."
"Why--what in the name of the Planets?" asked McLaurin. "It didn't kill
the men in the forts--why does it kill the men in the ships, when the
ships are protected?"
"The protection kills them."
"But--but they had the protective oscillations on all the way out!"
protested the Commander.
"Think how it works though. Think, man. The enemy's field is an
electric-field oscillation. We combat it by setting up a similar
oscillating field in the metal of the hull ourselves. Because the metal
conducts the strains, they meet, and oppose. It is not a shield--a
shield is impossible, as I have said, because of energy concentration
factors. If their beam carried a hundred thousand horsepower in a
ten-foot square beam, in every ten square feet of our shield, we'd have
to have one hundred thousand horsepower. In other words, hundreds of
times as much energy would be needed in the shield, as they used in
their beam. We can't afford that. We had to let the beams oppose our
oscillations in the metal, where, because the metal conducts, they meet
on an equal basis. But--when two oscillations of slightly different
frequency meet, what is the result?"
"In this case, a heterodyne frequency of a lower, and harmless
frequency."
"So I thought. I was partly right. It does _not_ harm the metal. But it
kills the men. It is super-sonic. The terrible, shrill sounds destroy
the cells of the men's bodies. Then, when their dead hands release the
controls, the automatic switches blow up the ship."
"God! We stop one menace--and it is like the Hydra. For every head we
lop off, two spring up."
"Ah--but they are lesser heads. Look, what is the fundamental difference
between sound and light?"
"One is a vibration of matter and the--ah--eliminate the material
contact!"
"Exactly! All we need to do is to let the ships operate airless, the men
in space suits. Then the air cannot carry the sounds to them. And by
putting special damping materials in their suits, we can stop the
vibrations that would reach them through their feet and hands. Another
six-man ship must go out--but this ship will come back!"
And with the order for another experimental ship, went the orders for
commercial supplies of this new apparatus. Every IP ship must be
equipped to resist it.
Buck Kendall sailed on the six-man scout that went out this time. Again
they swooped once at Phobos, again Miran scout-ships crumbled under the
attack of the vicious UV beams. The Mirans were not waiting
contemptuously this time. In an instant the great interstellar ship rose
from its berth, its weapons working angrily. The crumbler ray snapped
out at the T-253.
Kendall stared into the periscope visor intently. Clumsily his padded
hands worked at the specially adapted controls. The soft hiss of the
oxygen release into his suit disturbed him slightly. The radio-phones in
his helmet carried all the conversations in the ship to him with equal
clarity. He watched as the great ship angled angrily up--
His vision was momentarily obscured by a violet glow that built up and
reached out gently from every point of metal in the ship. The instant
Kendall saw that, the T-253 was fleeing under his hands. The test had
been made. Now all he desired was safety again. The ion-rockets flared
recklessly as, crushed under an acceleration of four Earth-gravities, he
sank heavily into his seat. Grimly the Miran ship was pursuing them,
easily keeping up with the fleeing midget. The crumbler became more
intense, the violet glow more vivid.
The UV beam was reaching out directly behind now. The--
With a cry of agony, Kendall ripped the radio-phone connection out of
his suit. A soft hiss of leaking air warned him of too great violence
only minutes later. For his ears had been deafened by the sudden shriek
of a tremendous signal from outside!
Instantly Kendall knew what that meant. And he could not communicate
with his men! There was no metal in these special suits, even the oxygen
tanks were made of synthetic plastics of tremendous strength. No scrap
of vibrating metal was permissible. The padded gloves and boots
protected him--but there was a new and different type of crackle and
haze from the metal points now. It was almost invisible in the
practically airless ship, but Kendall saw it.
Presently he felt it, as he desperately increased his acceleration. Slow
creeping heat was attacking him. The heat was increasing rapidly now.
Desperately he was working at the crumbler-protection controls--but
immediately set them back as they were. He had to have the crumbler
protection as well--!
* * * * *
Grimly the great Miran ship hung right beside them. Angrily the two
four-foot UV beams flashed back--seeking some weak spot. There were
none. At her absolute maximum of acceleration the little ship plunged
on. Gamma and atomic bombs were washing her in flame. The heavy blocks
of paraffin between her walls were long since melted, retained only by
the presence of the metal walls. Smoke was beginning to filter out now,
and Kendall recognized a new, and deadlier menace! Heat--quantities of
heat were being poured into the little ship, and the neutron guns were
doing their best to add to it. The paraffin was confined in there--and
like any substance, it could be volatilized, and as a vapor, develop
pressure--explosive pressure!
The Miran seemed satisfied in his tactics so far--and changed them.
Forty-seven million miles from Earth, the Miran simply accelerated a bit
more, and crowded the Solarian ship a bit. White-faced, Buck Kendall was
forced to turn a bit aside. The Miran turned also. Kendall turned a bit
more--
Flashing across his range of vision at an incredible speed, a tiny
thing, no more than twenty feet long and five in diameter, a scout-ship
appeared. Its tiny nose ultra-violet beam was blasting a solid cylinder
of violet incandescence a foot across in the hull of the Miran--and, to
the Miran, angling swiftly across his range of vision. Its magnetic
field clashed for a thousandth of a second with the T-253, instantly
meeting, and absorbing the fringing edges. Then--it swept through the
Miran's magnetic shield as easily. The delicate instruments of the scout
instantaneously adjusted its own magnetic field as much as possible.
There was resistance, enormous resistance--the ship crumpled in on
itself, the tail vanished in dust as a sweeping crumbler beam caught it
at last--and the remaining portion of the ship plowed into the nose of
the Miran.
The Miran's force-control-room was wrecked. For perhaps a minute and a
half, the ship was without control, then the control was
re-established--and in vain the telescopes and instruments searched for
the T-253. Lightless, her rockets out now, her fields damped down to
extinction, the T-253 was lost in the pulsing, gyrating fields of half a
dozen scout-ships.
Kendall looked grimly at the crushed spot on the nose of the Miran. His
ship was drifting slowly away from the greater ship. Presently, however,
the Miran put on speed in the direction of Earth, and the T-253 fell far
behind. The Miran was not seriously injured. But that scout pilot, in
sacrificing life, had thrown dust in their eyes for just those few
moments Kendall had needed to lose a lightless ship in lightless
space--lightless--for the Mirans at any rate. The IP ships had been
covered with a black paint, and in no time at all, Kendall had gotten
his ship into a position where the energy radiations of the sun made him
undetectable from the Miran's position, since the radiation of his own
ship, even in the heat range, was mingled with the direct radiation of
the sun. The sun was in the Miran's "eyes," both actual and
instrumental.
An hour later the Miran returned, passed the still-lightless ship at a
distance of five million miles, and settled to Phobos for the slight
repairs needed.
Twelve hours later, the T-253 settled to Luna, for the many
rearrangements she would need.
"I rather knew it was coming," Kendall admitted sadly, "but danged if I
didn't forget all about it. And--cost the life of one of the finest men
in the system. Jehnson's family get a permanent pension just twice his
salary, McLaurin. In the meantime--"
"What was it? Pure heat, but how?"
"Pure radio. Nothing but short-wave radio directed at us. They probably
had the apparatus, knew how to make it, but that's not a good type of
heat ray, because a radio tube is generally less than eighty percent
efficient, which is a whale of a loss when you're working in a battle,
and a whale of an inconvenience. We were heated only four times as much
as the Miran. He had to pump that heat into a heat-reservoir--a water
tank probably--to protect himself. Highly inefficient and ineffective
against a large ship. Also, he had to hold his beam on us nearly ten
minutes before it would have become unbearable. He was again, trying to
kill the men, and not the ship. The men are the weakest point,
obviously."
"Can you overcome that?"
"Obviously, no. The thing works on pure energy. I'd have to match his
energy to neutralize it. You knew it's an old proposition, that if you
could take a beam of pure, monochromatic light and divide it exactly in
half, and then recombine it in perfect interference, you'd have
annihilation of energy. Cancellation to extinction. The trouble is, you
never do get that. You can't get monochromatic light, because light
can't be monochromatic. That's due to the Heisenberg Uncertainty--my pet
bug-bear. The atom that radiates the light, must be moving. If it isn't,
the emission of the light itself gives it a kick that moves it. Now, no
matter what the quantum _might_ have been, it loses energy in kicking
the atom. That changes the situation instantly, and incidentally the
'color' of the light. Then, since all the radiating atoms won't be
moving alike, etc., the mass of light can't be monochromatic. Therefore
perfect interference is impossible.
"The way that relates to the problem in hand, is that we can't possibly
destroy his energy. We can, as we do in the crumbler stunt, change it.
He can't, I suspect, put too much power behind his crumbler, or he'd
have crumbling going on at home. We get a slight heating from it,
anyway. Into the bargain, his radio was after us, and his neutrons
naturally carried energy. Now, no matter what we do, we've got that to
handle. When we fight his crumbler, we actually add heat-energy to it,
ourselves, and make the heating effect just twice as bad. If we try to
heterodyne his radio--presto--it has twice the heat energy anyway,
though we might reduce it to a frequency that penetrated the ship
instead of all staying in it. But by the proposition, we have to use as
much energy, and in fact, remember the 80% rule. We've got to take it
and like it."
"But," objected McLaurin, "we _don't_ like it."
"Then build ships as big as his, and he'll quit trying to roast you.
Particularly if the inner walls are synthetic plastics. Did you know I
used them in the 'S Doradus' and 'Cepheid'?"
"Yes. Were you thinking of that?"
"No--just luck--and the fact that they're light, strong as steel almost,
and can be manufactured in forms much more quickly. Only the outer hull
is tungsten-beryllium. The advantage in this will be that nearly all the
energy will be absorbed outside, and we'll radiate pretty fast,
particularly as that tungsten-beryllium has a high radiation-factor in
the long heat range."
"What does that mean?"
"Well, ordinary polished silver is a mighty poor radiator. Homely
example: Try waiting for your coffee to cool if it's in a polished
silver pot. Then try it in a tungsten-beryllium pot. No matter how you
polish that tungsten-beryllium, the stuff WILL radiate heat. That's why
an IP ship is always so blamed cold. You know the passenger ships use
polished aluminum outer walls. The big help is, that the
tungsten-beryllium will throw off the energy pretty fast, and in a big
ship, with a whale of a lot of matter to heat, the Strangers will simply
give up the idea."
"Yes, but only two ships in the system compare with them in size."
"Sorry--but I didn't build the IP fleet, and there are lots of tungsten
and beryllium on Earth. Enough anyway."
"Will they use that beam on the fort? And can't we use the thing on
them?"
"They won't and we won't--though we could. A bank of those new million
watt tubes--perhaps a hundred of them--and we'd have a pretty effective
heater--but an awful waste of power. I've got something better."
"New?"
"Somewhat. I've found out how to make the mirror field in a plate of
metal, instead of a block. Come on to the lab, and I'll show you."
"What's the advantage? Oh--weight saved, and silver metal saved."
"A lot more than that, Mac. Watch."
* * * * *
At the laboratory, the new apparatus looked immensely lighter and
simpler than the old. The atostor, the ionizer, and the twin
ion-projectors were as before, great, rigid, metal structures that would
maintain the meeting point of the ions with inflexible exactitude under
any acceleration strains. But now, instead of the heavy silver block in
which a mirror was figured, the mirror consisted of a polished silver
plate, parabolic to be sure, but little more than a half-inch in
thickness. It was mounted in a framework of complex, stout metal braces.
Kendall started the ion-flame at low intensity, so the UV beam was
little more than a spotlight.
"You missed the point, Mac. Now--watch that tungsten-beryllium plate.
I'll hold the power steady. It's an eighteen-inch beam--and now the
energy is just sufficient to heat that tungsten plate to bright red.
But--"
Kendall turned over a small rheostat control--and abruptly the
eighteen-inch diameter spot on the tungsten-beryllium plate began
contracting; it contracted till it was a blazing, sparkling spot of
molten incandescence less than an inch across!
"That's the advantage of focus. At this distance of a few hundred feet
with a small beam I can do that. With a twenty-foot beam, I can get a
two-foot spot at a distance of nearly ten miles! That means that the
receiving end will have the pleasure of handling _one hundred times the
energy concentration_. That would punch a hole through most anything.
All you have to do is focus it. The trouble being, if it's out of focus
the advantage is more than lost. So if there's any question about
getting the focus, we'll get along without it."
"A real help, if you do. That would punch a hole before the Stranger
ship could turn away as they do now."
Kendall nodded. "That's what I was after. It is mainly for the forts,
though. We'll have to signal the dope to the Mars Center and Deenmor
stations. They can fix it up, themselves. In the meantime--all we can do
is hold on and hunt, and let's hope better than the Strangers do."
X
Sadly the convalescent Gresth Gkae listened to the reports of his
lieutenants. More and more disgraced he felt as he realized how badly he
had blundered in reporting the people of this system unable to cope with
the attackers' weapons. Gresth Gkae looked up at his old friend and
physician, Merth Skahl. He shook his head slowly. "I'm afraid, Merth
Skahl. I am afraid. We have, perhaps, made a mistake. The better and the
stronger alone should rule. Aye, but is the _stronger_ always the
_better_? I am afraid we have mistaken the Truth in assuming this. If we
have--then may Jarth, Lord of Truth and Wisdom punish us. Mighty Jarth,
if I have mistaken in following my judgments, it is not from
disobedience, it is lack of Thy knowledge. The strongest--they are not
always the better, are they?"
Merth Skahl bent sharply over his friend. "Quiet thyself, Gresth Gkae.
You know, and I know, you have done only your best, and surely Jarth
himself can ask no better of any one. You must rest, for only by rest
can those terrible burns be healed. All your _stheen_ over half the
body-area was burned off. You have been delirious for many days."
"But Merth Skahl, think--have we disobeyed Jarth's will? It is, we know,
his will that only the best and the strongest shall rule--but are the
best always the strongest? An imbecile adult could destroy the life of a
genius-grade child. The strongest wins, but not the best. Such would not
be the will of Jarth. If we be the stronger, _and_ the best, then it is
right and just that these strange creatures should be destroyed that we
may have a stable world of stable light and heat. But look and see, with
what terrible swiftness these strange creatures have learned! May it not
be they are the better race--that it is _we_ who are the weaker and the
poorer? Can it be that Jarth has brought us together that these people
might learn--and destroy us? If they be the stronger, and the
better--then may Jarth's will be done. But we must test our strength to
the utmost. I must rise, and go to my laboratory soon. They have set it
up?"
"Aye, they have, Gresth Gkae. But remember, the weak and the sick make
faults the strong and the well do not. Better that you rest yourself.
There is little you can do while your body seeks to recover from these
terrible burns."
"You are wrong, my friend, wrong. Don't you see that my mind is
clear--that it is the mind which must fight in these battles, for surely
the man is weak against such things as this infra-X-radiation? Why, I am
better able to fight now than are you, for I am a trained fighter of the
mind, while you are a trained healer of the body. These strange beings
with their stiff arms and legs, their tender skins, and--and their swift
minds have fought us all too well. If we must test, let it be a test. I
have heard how they so quickly solved the riddle of the crumbling field.
That took us longer, and we designed it. The Counsel of Worlds put me in
command, let me up, Skahl, I must work."
Concerned, the physician looked down at him. Finally he spoke again.
"No, I will not permit you to leave the hospital-ship. You must stay
here, but if, as you have said, the mind is what must fight, then surely
you can fight well from here, for your mind is here."
"No, I cannot, and you well know it. I may shorten my life, but what
matter. 'Death is the end toward which the chemical reaction, Life,
tends,'" quoted the scientist. "You know I have left my children--my
immortality is assured through them. I can afford to die in peace, if it
assures their welfare. Time is precious, and while my mind might work
from here, it must have data on which to work. For that, I must go to
the laboratories. Help me, Merth Skahl."
Reluctantly the physician granted the request, but begged of Gresth Gkae
a promise of at least six hours rest in every fifteen, and a good sleep
of at least twenty-seven hours every "night." Gresth Gkae agreed, and
from a wheelchair, conducted his work, began a new line of
experimentation he hoped would yield them the weapon they needed. Under
him, the staff of scientists worked, aiding and advising and suggesting.
The apparatus was built, tested, and found wanting. Time and again as
the days passed, they watched Gresth Gkae, gaining strength very, very
slowly, taken away despondent at the end of his forty hours of work.
A dozen expeditions were sent to Jupiter's poles to watch and measure
and study the tremendous auroral displays there, where Jupiter's vast
magnetic field sucked in countless quintillions of the flying electrons
from the sun, and brought them circling in, in a vast, magnificent
display of auroral ionization.
* * * * *
Expeditions went to the great Southern Plateau, the Plateau of Storms,
where the titanic air currents resulted in an everlasting display of
terrific lightnings, great burning balls of electric force floating
dangerous and deadly across the frozen, ultra-cold plain.
And the expeditions brought back data. Yet still Gresth Gkae could not
sleep, his thoughts intruding constantly. Hours Merth Skahl spent with
him, calming him to sleep.
"But what is this constant search? It is little enough I know of
science, but why do you send our men to these spots of wonderfully
beautiful, but useless natural forces. Can we somehow, do you think,
turn them against the people of these worlds?"
Softly the old Miran smiled. "Yes, you might say so. For look, it is the
strange balls of electric force I want to know about. Sthor had few, but
occasionally we saw them. Never were they properly investigated. I want
to know their secret, for I am sure they are balls of electric forces
not vastly dissimilar from the nucleus of the atom. Always we have known
that no system of purely electrical forces could remain stable. Yet
these strange balls of energy do. How is it? I am sure it will be of
vast importance. But the direct secret I hope to learn is in this: What
can be done with electric fields can nearly always be duplicated, or
paralleled in magnetic fields. If I can learn how to make these
electric balls of energy, can I not hope to make similar magnetic balls
of energy?"
"Yes, I see--that would seem true. But what benefit would you derive
from that? You have magnetic beams now, and yet they are useless because
you can get nowhere near the forts. How then would these benefit you?"
"We can do nothing to those forts, because of that magnetic shield.
Could we once break it down, then the fort is helpless, and one or two
small atomic bombs destroy it. But--we cannot stay near, for the
terrible infra-X-rays of theirs burn holes in our ships, and--in our
men.
"But look you, I can drop many atomic bombs from a distance where their
beams are ineffective. Suppose I _do_ make a magnetic ball of energy, a
magnetic bomb. Then--I can drop it from a distance! We have learned that
the power supply of these forts is very great--but not endless, as is
ours now, thanks to the vast supplies of power metal on this heavy
planet. Then all we need do is stay at a distance where they cannot
reach us--and drop magnetic bombs. Ah, they will be stopped, and their
energy absorbed. But we can keep it up, day after day, and slowly drain
out their power. Then--then our atomic bombs can destroy those forts,
and we can move on!" But suddenly the animation and strength left his
voice. He turned a sad, downcast face to his friend. "But Merth Skahl,
we can't do it," he complained.
"Ah--now I can see why you so want to continue this wearing and worrying
work. You need time, Gresth Gkae, only time for success. Tomorrow it may
be that you will see the first hint that will lead you to success."
"Ah--I only hope it, Merth Skahl, I only hope it."
But it was the next day that they saw the first glimpse of the secret,
and saw the path that might lead to hope and success. In a week they
were sending electric bombs across the laboratory. And in three days
more, a magnetic bomb streaked dully across the laboratory to a magnetic
shield they had set up, and buried itself in it, to explode in brilliant
light and heat.
From that day Gresth Gkae began to mend. In the three weeks that were
needed to build the apparatus into ships, he regained strength so that
when the first flight of five interstellar ships rose from Jupiter, he
was on the flagship.
To Phobos they went first, to the little inner satellite of Mars,
scarcely eight miles in diameter, a tiny bit of broken metal and rock,
utterly airless, but scarcely more than 3700 miles from the surface of
Mars below. The Mars Center and Deenmor forts were wasting no power
raying a ship at that distance. They could, of course, have damaged it,
but not severely enough to make up for the loss of their strictly
limited power. The photocells had been working overtime, every minute of
available light had been used, and still scarcely 2100 tons of charged
mercury remained in the tanks of Mars Center and 1950 in the tanks at
Deenmor.
The flight of five ships settled comfortably upon Phobos, while the
three relieved of duty started back to Jupiter. Immediately work was
begun on the attack. The ships were first landed on the near side, while
the apparatus of the projectors was unloaded, then the great ships moved
around to the far side. Phobos of course rotated with one face fixed
irrevocably toward Mars itself, the other always to the cold of space.
Great power leads trailed beneath the ships, and to the dark side. Then
there were huge water lines for cooling. On this almost weightless
world, where the great ships weighing hundreds of thousands of tons on a
planet, weighed so little they were frequently moved about by a single
man, the laying of five miles of water conduit was no impossibility.
Then they were ready. Mars Center came first. Automatic devices kept the
aim exact, as the first of the magnetic bombs started down. At
five-second intervals they were projected outward, invisible globes of
concentrated magnetic energy, undetectable in space. Seven seconds
passed before the first became dimly visible in the thin air of Mars. It
floated down, it would miss the fort it seemed--so far to one side--
Abruptly it turned, and darted with tremendously accelerating speed for
the great magnetic field of the fort. With a vast blast of light, it
exploded. Five seconds later a second exploded. And a third.
Mars Center signaled scoffingly that the bombs were all being stopped
dead in the magnetic atmosphere, after the bombardment had been
witnessed from Earth and Luna. An hour later they gave a report that
they were concentrated magnetic fields of energy that would be rather
dangerous--if it weren't that they couldn't even stand into the magnetic
atmosphere. Three hours later Mars Center reported that they contained
considerably more energy than had at first been thought. Further, which
they had not carefully considered at first, they were taking energy with
them! They were taking away about an equal amount of energy as each blew
up.
It was only a half-hour after that that the men at Mars Center realized
perfectly what it meant. Their power was being drained just a little bit
better than twice as fast as they generated during the day--and since
Phobos spun so swiftly across the sky.
Deenmor got the attack just about the time Mars Center was released.
Deenmor immediately began seeking for the source of it. Somewhere on
Phobos--but where?
The Mirans were experts at camouflage. Deenmor Station, realizing the
menace, immediately rayed the "projector." They tore up a great deal of
harmless rock with their huge UV rays. But the bomb device continued to
throw one bomb each five seconds.
When Deenmor operated from Phobos' position, Mars Center was exposed to
the deadly, constant drain. A day or two later, the bombs were coming
one each second and a half, for more ships had joined in the work on
Phobos.
Gresth Gkae saw the work was going nicely. He knew that now it was only
a question of time before those magnetic shields would fail--and then
the whole fort would be powerless. Maybe--it might be a good idea, when
the forts were powerless to investigate instead of blowing them up.
There might be many interesting and worthwhile pieces of
apparatus--particularly the UV beam's apparatus.
XI
Buck Kendall entered the Communications room rather furtively. He hated
the place. Cole was there, and McLaurin. Mac was looking tired and
drawn, Cole not so tired, but equally drawn. The signals were coming
through fairly well, because most of the disturbance was rising where
the signals rose, and all the disturbance, practically, was magnetic
rather than electric.
"Deenmor is sending, Buck," McLaurin said as he entered. "They're down
to the last fifty-five tons. They'll have more time now--a rest while
Phobos sinks. Mars Center has another 250 tons, but--it's just a
question of time. Have you any hope to offer?"
"No," said Kendall in a strained voice. "But, Mac, I don't think men
like those are afraid to die. It's dying uselessly they fear. Tell
'em--tell 'em they've defended not alone Mars, but all the system, in
holding up the Strangers on Mars. We here on Luna have been safer
because of them. And tell--Mac, tell them that in the meantime, while
they defended us, and gave us time to work, we have begun to see the
trail that will lead to victory."
"_You have!_" gasped McLaurin.
"No--but they will never know!" Kendall left hastily. He went and stood
moodily looking at the calculator machines--the calculator machines that
refused to give the answers he sought. No matter how he might modify
that original idea of his, no matter what different line of attack he
might try in solving the problems of Space and Matter, while he used the
system he _knew_ was right--the answer came down to that deadly,
hope-blasting expression that meant only "uncertain."
Even Buck was beginning to feel uncertain under that constant crushing
of hope. Uncertainty--uncertainty was eating into him, and destroying--
From the Communications room came the hum and drive of the great sender
flashing its message across seventy-two millions of miles of nothing.
"B-u-c-k K-e-n-d-a-l-l s-a-y-s h-e h-a-s l-e-a-r-n-e-d s-o-m-e-t-h-i-n-g
t-h-a-t w-i-l-l l-e-a-d t-o v-i-c-t-o-r-y w-h-i-l-e y-o-u h-e-l-d
b-a-c-k t-h-e--"
Kendall switched on a noisy, humming fan viciously. The too-intelligible
signals were drowned in its sound.
"And--tell them to--destroy the apparatus before the last of the power
is gone," McLaurin ordered softly.
The men in Deenmor station did slightly better than that. Gradually they
cut down their magnetic shield, and some of the magnetic bombs tore and
twisted viciously at the heavy metal walls. The thin atmosphere of Mars
leaked in. Grimly the men waited. Atomic bombs--or ships to investigate?
It did not matter much to them personally--
Gresth Gkae smiled with his old vigor as he ordered one of the great
interstellar ships to land beside the powerless station, approaching
from such an angle that the still-active Mars Center station could not
attack. One of the fleet of Phobos rose, and circled about the planet,
and settled gracefully beside the station. For half an hour it lay there
quietly, waiting and watching. Then a crew of two dozen Mirans started
across the dry, crumbly powder of Mars' sands, toward the fort.
Simultaneously almost, three things happened. A three-foot UV beam wiped
out the advancing party. A pair of fifteen-foot beams cut a great gaping
hole in the wall of the interstellar ship, as it darted up, like a
startled quail, its weapons roaring defiance, only to fall back,
severely wounded.
And the radio messages pounded out to Earth the first description of the
Miran people. Methodically the men in Deenmor station used all but one
ton of their power to completely and forever wreck and destroy the
interstellar cripple that floundered for a few moments on the sands a
bare mile away. Presently, before Deenmor was through with it, the
atomic bombs stopped coming, and the atomic shells. The magnetic shield
that had been re-established for the few minutes of this last, dying
sting, fell.
Deenmor station vanished in a sudden, colossal tongue of blue-green
light as the ton of atomically distorted mercury was exploded by a
projector beam turned on the tank.
* * * * *
It was long gone, when the first atomic bombs and magnetic bombs dropped
from Phobos reached the spot, and only hot rock and broken metal
remained.
Mars Center failed in fact the next time Phobos rode high over it. The
apparatus here had been carefully destroyed by technicians with a view
of making it indecipherable, but the Mirans made it even more certain,
for no ship settled here to investigate, but a stream of atomic bombs
that lasted for over an hour, and churned the rock to dust, and the dust
to molten lava, in which pools of fused tungsten-beryllium alloy bubbled
slowly and sank.
"Ah, Jarth--they are a brave race, whatever we may say of their queer
shape," sighed Gresth Gkae as the last of Mars Center sank in bubbling
lava. "They stung as they died." For some minutes he was silent.
"We must move on," he said at length. "I have been thinking, and it
seems best that a few ships land here, and establish a fort, while some
twenty move on to the satellite of the third planet and destroy the fort
there. We cannot operate against the planet while that hangs above us."
Seven ships settled to Mars, while the fleet came up from Jupiter to
join with Gresth Gkae's flight of ships on its way to Luna.
An automatically controlled ship was sent ahead, and began the
bombardment. It approached slowly, and was not destroyed by the UV beams
till it had come to within 40,000 miles of the fort. At 60,000 Gresth
Gkae stationed his fleet--and returned to 150,000 immediately as the
titanic UV beams of the Lunar Fort stretched out to their maximum range.
The focus made a difference. One ship started limping back to Jupiter,
in tow of a second, while the rest began the slow, methodical work of
wearing down the defenses of the Lunar Fort.
Kendall looked out at the magnificent display of clashing, warring
energies, the great, whirling spheres and discs of opalescent flame, and
turned away sadly. "The men at Deenmor must have watched that for days.
And at Mars Center."
"How long can we hold out?" asked McLaurin.
"Three weeks or so, at the present rate. That's a long time, really. And
we can escape if we want to. The UV beams here have a greater range than
any weapon the Strangers have, and with Earth so near--oh, we could
escape. Little good."
"What are you going to do?"
"I," said Buck Kendall, suddenly savage, "am going to consign all the
math machines in the universe to eternal damnation--and go ahead and
build a machine anyway. I _know_ that thing ought to be right. The
math's wrong."
"There is no other thing to try?"
"A billion others. I don't know how many others. We ought to get atomic
energy somehow. But that thing infuriates me. A hundred things that math
has predicted, that I have checked by experiment, simple little things.
But--when I carry it through to the point where I can get something
useful--it wriggles off into--uncertainty."
Kendall stalked off to the laboratory. Devin was there working over the
calculus machines, and Kendall called him angrily. Then more apologetic,
he explained it was anger at himself. "Devin, I'm going to make that
thing, if it blows up and kills me. I'm going to make that thing if this
whole fort blows up and kills me. That math has blown up in my face for
four solid months, and half killed me, so I'm going to kill it. Come on,
we'll make that damned junk."
Angrily, furiously, Kendall drove his helpers to the task. He had worked
out the apparatus in plan a dozen times, and now he had the plans turned
into patterns, the patterns into metal.
Saucily, the "S Doradus" made the trip to and from Earth with patterns,
and with metal, with supplies and with apparatus. But she had to dodge
and fight every inch of the way as the Miran ships swooped down angrily
at her. A fighting craft could get through when the Miran fleet was
withdrawn to some distance, but the Mirans were careful that no
heavy-loaded freighter bearing power supply should get through.
And Gresth Gkae waited off Luna in his great ship, and watched the
steady streams of magnetic bombs exploding on the magnetic shield of the
Lunar Fort. Presently more ships came up, and added their power to the
attack, for here, the photo-cell banks could gather tremendous energy,
and Gresth Gkae knew he would need to overcome this, and drain the
accumulated power.
Gresth Gkae felt certain if he could once crack this nut, break down
Earth, he would have the system. This was the home planet. If this fell,
then the two others would follow easily, despite the fact that the few
forts on the innermost planet, Mercury, could gather energy from the sun
at a rate greater than their ships could generate.
It took Kendall two weeks and three days to set up his preliminary
apparatus. They had power for perhaps four days more, thanks to the fact
that the long Lunar day had begun shortly after Gresth Gkae's impatient
attack had started. Also, the "S Doradus" had brought in several hundred
tons of charged mercury on each trip, though this was no great quantity
individually, it had mounted up in the ten trips she had made. The
"Cepheid," her sister ship, had gone along on seven of the trips, and
added to the total.
But at length the apparatus was set up. It was peculiar looking, and it
employed a great deal of power, nearly as much as a UV beam in fact.
McLaurin looked at it sceptically toward the last, and asked Buck: "What
do you expect it to do?"
"I am," said Kendall sourly, "uncertain. The result will be uncertainty
itself."
Which, considering things, was a surprisingly accurate statement.
Kendall gave the exact answer. He meant to give an ironic comment. For
the mathematics had been perfectly correct, only Buck Kendall
misinterpreted the answer.
"I've followed the math with mechanism all the way through," he
explained, "and I'm putting power into it. That's all I know. Somewhere,
by the laws of cause and effect, this power _must_ show itself
again--despite what the damn math says."
And in that, of course, Kendall was wrong. Because the laws of cause and
effect didn't hold in what he was doing now.
"Do you want to watch?" he asked at length. "I'm all set to try it."
"I suppose I may as well." McLaurin smiled. "In our close-knit little
community the fate of one is of interest to all. If it's going to blow
up, I might as well be here, and if it isn't, I want to be."
Kendall smiled appreciatively and replied: "Let it be on thy own head.
Here she goes."
He walked over to the power board, and took command. Devin, and a squad
of other scientists were seated about the room with every conceivable
type and combination of apparatus. Kendall wanted to see what this was
doing. "Tubes," he called. "Circuits A and D. Tie-ins." He stopped, the
preliminary switches in. "Main circuit coming." With a jerk he threw
over the last contact. A heavy relay thudded solidly. The hum of a
straining atostor. Then--
An electric motor, humming smoothly stopped with a jerk. "This," it
remarked in a deep throaty voice, "is probably the last stand of
humanity."
The galvanometer before which Devin was seated apparently agreed. In a
rather high pitched voice it pointed out that: "If the Lunar Fort falls,
the Earth--" It stopped abruptly, and an electroscope beside Douglass
took up the thread in a high, shrill voice, rather slurred, "--will be
directly attacked."
"This," resumed the motor in a hoarse voice, "will certainly mean the
end of humanity." The motor gave up the discourse and hummed violently
into action--in reverse!
"My God!" Kendall pulled the switch open with a sagging jaw and staring
eyes.
The men in the room burst into sudden startled exclamations.
Kendall didn't give them time. His jaw snapped shut, and a blazing light
of wondrous joy shone in his eyes. He instantly threw the switch in
again. Again the humming atostor, the strain--
Slowly Devin lifted from his seat. With thrashing arms and startled,
staring eyes, he drifted gently across the room. Abruptly he fell to the
floor, unhurt by the light Lunar gravity.
"I advise," said the motor in its grumbling voice, "an immediate
exodus." It stopped speaking, and practiced what it preached. It was a
fifty-horse motor-generator, on a five-ton tungsten-beryllium base, but
it rose abruptly, spun rapidly about an axis at right angles to the axis
of its armature, and stopped as suddenly. In mid air it continued its
interrupted lecture. "Mercury therefore is the destination I would
advise. There power is sufficient for--all machines." Gently it inverted
itself and settled to the middle of the floor. Kendall instantly cut the
switch. The relay did not chunk open. It refused to obey. Settled in the
middle of the floor now, torn loose from its power leads, the
motor-generator began turning. It turned faster and faster. It was
shrilling in a thin scream of terrific speed, a speed that should have
torn its windings to fragments under the lash of centrifugal force.
Contentedly it said throatily. "Settled."
The galvanometer spoke again in its peculiar harsh voice. "Therefore,
move." Abruptly, without apparent reason, the stubborn relay clicked
open. The shrilly screaming motor stopped dead instantly, as though it
had had no real momentum, or had been inertialess.
Startled, white-faced men looked at Kendall. Buck's eyes were shining
with an unholy glee.
"_Uncertainty!_" he shouted. "Uncertainty--uncertainty--uncertainty,
you fools! Don't you see it? All the math--it said uncertainty--man,
man--_we've got just that--uncertainty_!"
"You're crazy," gasped McLaurin. "I'm crazy, everything's gone crazy."
Kendall roared with sudden, joyous laughter. "Absolutely. Everything
goes crazy--_the laws of nature break down_! Heisenberg's principle
showed that the law of cause and effect weren't absolute. We've made
them absolutely uncertain!"
"But--but motors _talking_, instruments giving lectures--"
"Certainly--or rather uncertainly--anything, absolutely anything. The
destruction of the laws of gravity, freedom from inertia--why, merely
picking up a radio lecture is nothing!"
Suddenly, abruptly, a thousand questions poured in on him. Jubilantly he
answered what he could, told what he thought--and then brought order.
"The battle's still on, men--we've still got to find out how to use
this, now we've got it. I have an idea--that there's a lot more. I know
what I'll get this time. Now help me remake this apparatus so we don't
broadcast the thing."
At once, ten times the former pace, work was done. On the radio, news
was sent out that Kendall was on the right track after all. In two hours
the apparatus had been vastly altered, it was in the final stage, and an
entirely different sort of field set up. Again they watched as Buck
applied the power.
The atostor hummed--but no strange tricks of matter happened this time.
The more concentrated, altered field was, as Buck was to find out later,
"Uncertainty of the Second Degree." It was molecular uncertainty. In a
field a foot and a half in diameter, Buck saw the thing created--and
suddenly a brilliant green-blue flame shot up, and a great dark cloud of
terrible, red-brown deadly vapor. Then an instant later, Kendall had
opened the relay. Gasping, the men ran from the laboratory, shutting the
deadly fumes in. "N{2}O{4}" gasped Morton, the chemist, as they reached
safety. "It's exothermic--but it formed there!"
In that instant, Kendall grasped the meaning the choking fumes carried.
"Molecular uncertainty!" he decided. "We're going back--we're getting
there--"
He altered the apparatus again, added another atostor in series, reduced
the size of his sphere of forces--of strange chaos of uncertainty.
Within--little was certain. Without--the laws of nature applied as ever.
Again the apparatus was started, cautiously this time. Only a strange
jumbled ionization appeared this time, then a slow, rising blue flame
began to creep up, and burn hot and blue. Buck looked at it for a
moment, then his face grew tense and thoughtful. "Devin--give me a
half-dollar." Blankly, Devin reached in his pocket, and handed over the
metal disc. Cautiously Buck Kendall tossed it toward the sphere of
force. Instantly there was a flash of flame, soundless and soft-colored.
Then the silver disc was outlined in light, and swiftly, inevitably
crumbling into dust so fine only a blue haze appeared. In less than two
seconds, the metal was gone. Only the dense blue fog remained. Then this
began to go, and the leaping blue flame grew taller, and stronger.
"We're on the track--I'm going to stop here, and calculate. Bring the
data--"
Kendall shut off the machine, and went to the calculation room. Swiftly
he selected already prepared graphs, graphs of the math he had worked
on. Devin came soon, and others. They assembled the data and with tables
and arithmetical machines turned it into graphs.
Then all these graphs were fed into the machine. There were curves, and
sine-curves, abrupt breaking lines--but the answer that came when all
were compounded was a perfect diagram of a flight of four steps,
descending in unequal treads to zero.
Kendall looked at it for long minutes. "That," he said at length, "is
what I expected. There are four degrees of uncertainty, we generated
'Uncertainty of the First Degree,' 'Mass Uncertainty,' when we started.
That, as here shown, takes little energy concentration. Then we
increased the energy concentration and got 'Uncertainty of the Second
Degree,' 'Molecular Uncertainty.' Then I added more power, and reduced
the field, and got 'Uncertainty of the Third Degree'--'Atomic
Uncertainty.' There is 'Uncertainty of the Fourth Degree.' It is barely
attainable with our atostors. It is--utter uncertainty.
"In the First Degree, the laws of mass action fail, the great
broad-reaching laws. In the Second Degree, the laws of the molecules, a
finer organization, break down, and anything can happen in chemistry. In
the Third Degree, the laws of atomic physics break down slowly. The atom
is tough. It is very compact, and we just barely attained the
concentration needed with that apparatus. But--in the Third Degree, when
the Atomic Laws break down into utter uncertainty, the atoms break, and
only hydrogen can exist. That was the blue flame.
"But the Fourth Degree--_there is no law whatsoever_, nothing in all the
Universe can exist. It means--_the utter destruction and release of the
energy of matter_!" Kendall paused for a moment. "We have won, with
this. We need only make up this apparatus--and maybe make it into a
weapon. You know, in the Fourth Degree, nothing in all the Universe
could resist, deflect, or control it, if launched freely, and
self-maintaining. I think that might be done. You see, no law affects
it, for it breaks down the law. Magnetism cannot attract or repel it
because magnetic fields cannot exist; there is no law of magnetic force,
where this field is.
"And you know, Devin, how I have analyzed and duplicated their magnetic
ball-fields. This should be capable of formation into a ball-field.
"We need only make it up now. We will install it in the 'S Doradus' and
the 'Cepheid' as a weapon. We need only install it as an energy source
here. Let us start."
XII
Buck Kendall with a slow smile, looked out of the port in the thick
metal wall. The magnetic shield of the Lunar Fort was washed constantly
with the fires of exploding magnetic bombs. The smile spread broader.
"My friends," he said softly, "you can pull from now till doomsday as
far as I'm concerned, and you won't even disturb us now." He looked back
over his shoulder into the power room. A hunched bulk, beautifully
designed and carefully finished, the apparatus that created 'Uncertainty
of the Fourth Degree' was destroying matter, and creating by its
destruction terrific electric fields. These fields were feeding the
magnetic shield now. Under the present drain, the machine was not
noticeably working. In fact, Kendall was a bit annoyed. He had tested
out the energy generating properties of this machine, trying to find a
limit. He had found there was no limit. The great copper conductors,
charged with the same atostor force that was used in the mercury fuel,
were perfect conductors, they had not heated. But the eleven thousand
tons of discharged mercury metal had been completely charged in just a
bit better than eleven minutes. The pumps wouldn't force it through the
charging apparatus any faster than that.
Two weeks more had passed, while the "S Doradus" and the "Cepheid" were
fitted out with the new apparatus Buck had designed. They were almost
ready to start now.
McLaurin came down the corridor, and stopped near Kendall. He too smiled
at the Miran's attempts. "They've got a long way to go, Buck."
"They're going a long way. Clear back home--and we'll be right along. I
don't think they can outdistance us."
"I still don't see why you couldn't use one of those Uncertainty
conditions--the First Degree perhaps, and annihilate our inertia."
"You can't control Uncertainty. By its essential character it's beyond
control."
"What's that Fourth Degree machine of yours--the material energy--if it
isn't controlled and utilized Uncertainty?"
"It's utter and utterly uncontrolled Uncertainty. The matter within that
field breaks down to absolutely nothing. Within, no law whatsoever
applies, but fortunately, outside the old laws of physics apply--and we
can gather and use the energy which is released outside, though nothing
can be done inside. Why, think, man, if I could control that
Uncertainty, I could do anything at all, absolutely anything. It would
be a world as unreasonable as a bad dream. Think how unreasonable those
manifestations we first got were!"
"But can't you get any control at all?"
"Very little. Anyway, if I could get inertialess conditions at will, I'd
be afraid of them. They'd make chemical reactions impossible in all
probability--and life is chemical. Two atoms must come into more or less
violent contact before a union takes place, and cannot if they have
neither momentum nor inertia.
"Anyway--why worry. I can't do it, because I can't control this thing.
And we have the extra-space drive."
"How does that darned thing work? Can't you drop the math and tell me
about it?"
Kendall smiled. "Not too readily. Remember first, as to the driving
system, that it works on the fabric of space. Space is, in the physical
sense, a fabric woven of the threads of lines of force from every body
in the universe, made up of fields and forces. It is elastic, and can
transmit strains. But anything that can transmit strains, can be
strained against. With the tremendous field intensities available by the
material engines, I can get such fields as will 'dig their toes' into
space and push.
"That's the drive itself. It is accelerationless, because it enfolds us,
and acts equally on every atom of us. By maintaining in addition a
slight artificial gravity--thanks also to the intensity of those
material engine fields--we can be comfortable, while we accelerate at
tremendous rates.
"That is, I think, at least allied to the Stranger's system. For the
high-speed drive, I do in fact use the Uncertainty. I can control it in
a certain sense by determining its powers, and the limits of
uncertainty, whether First, Second, Third or Fourth Degree. It advances
in jumps--but on a finer plotting of the curve, you can see that each
jump represents a vast series of smaller jumps. That is, there is Class
A, B, C, D, and so forth Uncertainty of the First Degree. Now Class A
First Degree Uncertainty involves only the deepest, broadest principles.
Only they break down. One of these is the law of the speed of light.
"I'm sure that isn't the system the Strangers use, but I'm also sure
there's no limit to the speed we can get."
"Doesn't that wreck your drive system?"
"No, because gravity and the fields I use in driving are First Degree
Uncertainties of the higher classes.
"But at any rate, it will work. And--I suspect you came to say you were
ready to go."
"I did." McLaurin nodded.
"Still stick to your original plan?"
McLaurin nodded. "I think it's best. You follow those fellows back to
their system in the 'S Doradus' and I'll stay here in the 'Cepheid' to
protect the system. They may need some time to get out of the place
here. And remember, we ought to be as decent as they were. They didn't
bother the transports leaving Jupiter when they came in, only attacked
the warships. We're bound to do the same, but we'll have to keep a watch
on them, nonetheless. So you go on ahead."
They started down the corridor, and came presently to the huge locks
where the "S Doradus" and the "Cepheid" were berthed. The super-ships
lay cold and gray now, men swarming in and out with last-minute
supplies. Air, water, spare parts, bedding and personal equipment.
Douglass, Cole, and most of the laboratory staff would go with Kendall
when he followed the Strangers home. Devin and a few of the most
advanced physicists would stay with McLaurin in case of need.
* * * * *
An hour later the "S Doradus" rose gently, soundlessly from her berth,
and floated out of the open lock-door. The "Cepheid" followed her in
five seconds. Still under the great screen of the fort, the lashing,
coruscating colors of the magnetic bombs and the magnetic screen flashed
and was iridescent. The "S Doradus" poked her great nose gently through
the screen, and an instant later her titanically powerful,
material-engine effortlessly discharged a great magnetic bomb, sent with
the combined power of five atomic-powered interstellar ships. The two
ships separated now, the "Cepheid" under McLaurin flashing ahead with
sudden, terrific acceleration toward Mars, whispering through space at a
speed that made it undetectable, faster than light. The "S Doradus"
journeyed out leisurely toward the fleet of forty-seven Miran ships.
Gresth Gkae saw the "S Doradus" and as he watched the steady progress,
felt sudden fear at his heart. The ship seemed so certain--
At a distance of thirty thousand miles, Kendall stopped. Magnetic bombs
were washing his screen continuously now, seeking to exhaust the ship as
all the great ships beyond poured their energy against it. A slow smile
spread over Kendall's mouth as he heard the gentle hum of the barely
working material-engine. Carefully he aligned the nose UV beam of the "S
Doradus" on the nearest of the Miran ships. Then he depressed a switch.
There was no ion-release before the force-mirror now. Just a jet of gas
whirling into a half-inch field of "Uncertainty of the Fourth Degree."
The matter vanished instantly in released energy so stupendous that the
greatest previous UV beams had been harmless things by comparison.
Material energy maintained the mirror forces. Material energy gave the
power that was released. And only material energy could have stood up
before it. Thirty thousand miles away, a Miran ship flamed
instantaneously into inconceivable incandescence, vanishing almost in
blue-violet light of terrific intensity. The ship reeled away, a
half-molten wreck.
The beam spotted two more ships before it winked out. Then Kendall began
sending bombs. He moved up to within 2000 miles that his aim might be
accurate. They were bombs of "Uncertainty of the Third Degree," the
Uncertainty of atomic law in bomb form. One hit the nose of the nearest
ship, and a sphere five feet in diameter glowed mistily blue for a
moment. Then very easily, the matter that formed the wall of the cruiser
began to run and change, and presently there was only a hole, and an
expanding cloud of gas. Three more flowed toward it--and the hole
enlarged, and another hole appeared in a bulkhead behind.
Kendall made a change. For the first time there came the staccato bark
of the material engine under strain, as it fashioned the terrific fields
of "Uncertainty of the Ultimate Degree." Abruptly they leapt out,
invisible till they entered a magnetic screen, then run over with
opalescent light as the energy of the field was sucked into them and
released.
It struck the nose of a ship--a field no larger than an apple--
A titanic gout of energy burst out that was soundless in space. The ship
suddenly opened back, opened like the peel of a banana, till a little
nub remained at the further end, and the metal flaps dropped back across
and behind it dejectedly. A second ship was struck, and it was struck on
one side, so that it was shattered like a spent firecracker.
Then the Miran fleet vanished in speed.
Kendall followed them. "I think," he said with a grin, "they tried to
use their radio beam, but it spread too much to do anything at that
distance. And they used their rotating magnetic field, which we couldn't
feel. And their crumbler ray too, of course. I wonder--are they headed
only for Jupiter? No--no, they've passed it!"
Faster than light, faster than energy could follow through space, or
Uncertainty Bombs pursue, the Mirans were fleeing for home. They knew
now that only in speed lay safety. Already they knew that a similar ship
had appeared off Jupiter, and, after wiping out the Phobos and Mars
stations with one bomb each, had cleared the Jovian Satellites with
equal terrible efficiency.
In one of the fleeing ships was a broken, tired old man, and his staff.
Gresth Gkae looked back at the blank, distorted space behind them, at
the swiftly dwindling sun, and spoke. "I was at fault, my friends. Jarth
has spoken. _They_ are the stronger and the wiser race. Farth Skalt has
shown you--they use space fields of intensity 100. That means the energy
of the ultimate destruction. Jarth used us as his instrument of testing,
only to drive and stimulate that race. I do not--nay. There is no doubt
now, for look."
Plainly visible, rapidly overtaking them, the "S Doradus" appeared
sharp, and luminous on the jet of distorted space.
"We cannot escape, my friends. Shall we return to Sthor or remain in
space, lost?"
"Let us deflect our course--at least he may not know our destination."
The interstellar ship turned very slightly in her course. Plainly they
saw the "S Doradus" flash on, in a straight line, headed for distant,
red-glowing Mira. Gresth Gkae watched, and shrugged. Silently he put the
ship back on its course, at its utmost speed. Parallel with them, near
to them, the "S Doradus" flashed on. Day after day, the two hurled
through space faster than light. Gradually Mira brightened, and at last
became a disc.
* * * * *
Gresth Gkae slowed his ships, and Kendall, watching, slowed to match his
speed. Five billion miles from Sthor, they had reached normal space
speeds. Viciously the Miran fleet attacked the lone ship from Earth.
Their rays, their bombs, their every weapon was flaming. Great
interstellar ships flashed suddenly into speeds greater than that of
light, seeking to ram and destroy the smaller ship. The "S Doradus"
flashed into equal or greater speed, and eluded them.
Kendall had determined now, which was the leader's ship.
Gresth Gkae watched dully as his ships attempted to destroy the single,
small ship. He sighed in resignation, and turned to walk back to the
chapel aboard the ship. One last prayer to Jarth--
Gresth Gkae stopped abruptly. The great ship was lurching strangely. Men
shouted sudden, frightened cries. The clanking and thud of relays
sounded, the shrill of alarms. Then the alarms stopped, and suddenly the
whole great ship vibrated to an infinitely deep voice speaking in
perfect Sthorian. The voice remarked solemnly, in great, vibrant tones,
that they would certainly receive news presently from the Expeditions.
It went on for some seconds to discuss the conditions as reported in the
new system. Then it stopped abruptly. An electric motor just above
Gresth Gkae's head suddenly hummed into action without reason or power
connection. Almost simultaneously he heard the shouts of startled men as
the great lock doors began to open into space of their own accord,
bulkhead doors slipped shut as the roar of escaping air echoed in the
ship.
Then it was all over. Gresth Gkae ran to the control room. The Mirans
there looked up at him with drawn faces.
"The instruments--Gresth Gkae--the instruments. The instruments read
impossible things, the motors worked without reason, the fields
fluctuated--the atomic engines stopped and the magnetic shield broke
down and gripped part of the ship instead!" reported the bewildered
pilot.
"I do not know--some strange weapon of--" began the old scientist.
Something luminous and huge twisted suddenly through space toward them,
a bomb of "Uncertainty of the First Degree." It wrapped the ship
silently--and again strange things happened. Abruptly the ship started
whirling violently, yet without centrifugal force. The heavens wheeled
crazily, and turned about three axes simultaneously. There was no
gyroscopic effect to hold them!
Gradually the thing died out. Then a great field seemed to catch the
ship, and hurl it away from its companions. Abruptly the pilot applied
all his power to pull free. In vain.
Gresth Gkae shook his head slowly, and raised the pilot's hands from the
board. "Let them do as they will. I think they mean us no real harm,
Thart Kralt. They can, we know, destroy us in an instant. Perhaps he
wants us to go somewhere with him"--Gresth Gkae smiled sadly--"and
anyway, we can do nothing."
For nearly a billion miles the great ship was hurled through space at
tremendous normal-space velocity. Then abruptly it was halted, without a
sign of strain or hurt. The great twenty-foot UV beam on the nose of the
"S Doradus" broke into glowing gentle red light. It flashed twice. There
was a pause. Then it flashed four times. A long wait. Then three times,
a pause and nine times. A wait. Four times, a pause, sixteen times. Then
it stopped.
A slow smile of ineffable joy spread over Gresth Gkae's face. "Jarth Be
Praised. He can destroy, but does not wish to. Ah, Thart Kralt, turn
your spotlight toward him, and flash it twenty-five times, for he is
trying to start communications with us. Jarth is wise beyond all
understanding. They were the weaker race, and they are the stronger. But
also they are the better, for they could destroy, and they do not, but
seek only to communicate."
EPILOGUE
The interstellar liner "Mirasol" settled gently to Sthor, having circled
wide of Asthor, and from her hold a cargo of the heavy Jovian elements
was discharged, while a mixed stream of Solarians and Mirans came from
her passenger quarters.
A delegation of Mirans met the new Ambassador from Sol, Commander
McLaurin, and conducted him joyfully to the Central Government Group.
Beside the great buildings, a battered, scarred interstellar ship lay,
her rear section a mass of great patches, rudely applied, and rudely
made, mere cast metal plates.
Gresth Gkae welcomed Commander McLaurin to the Government Hall. "Your
arrival today, Commander McLaurin, was most fortunate," he said in the
interstellar language that had been developed, "for but yesterday Gresth
Talak, my brother, arrived in his ship. Before we made that
fortunate-unfortunate expedition against your system, we waited for him,
and he did not come, so we knew his ship had, like others, been lost.
"He arrived only yesterday, some seventy hours ago, and explained how it
had come about. He too found a solar system. But he was less fortunate
than I, and while exploring this uninhabited system, far out still from
the central sun, where there should have been no masses of matter, one
of those rare things, a giant stony meteor that even a magnetic shield
will not stop careened into the rear of his ship. Damaged badly, barely
able to move, they settled to a planet. The atmosphere was breathable,
the temperature mild. But while they could navigate planetary
distances, they could not return, so for nearly four and a half of your
years they remained there, working, working to repair their ship.
"They have done it at last. And they have returned. And best of all,
after a four-year stay there, they know all they need know about that
system of eleven planets. It is compact as yours, with an ultra-light
sun such as yours, and four of the planets are habitable. Together we
can colonize that system! It is a system of stable heat and stable
light. And it is small, yet large enough. And with the devices such as
your new energy has permitted, we need never fear the stony meteors
again." Gresth Gkae smiled happily. "Still better--it is inhabited only
by the lowest forms of life. It is too costly to both races when Jarth
sees fit to stimulate them by throwing one against the other, despite
the good things that may come later."

"Defects," such as, but not limited to, incomplete, inaccurate or

property infringement, a defective or damaged disk or other medium, a

Section 2. Information about the Mission of Project Gutenberg-tm
Project Gutenberg-tm is synonymous with the free distribution of
electronic works in formats readable by the widest variety of computers
including obsolete, old, middle-aged and new computers. It exists
because of the efforts of hundreds of volunteers and donations from
people in all walks of life.
Volunteers and financial support to provide volunteers with the
assistance they need, is critical to reaching Project Gutenberg-tm's
goals and ensuring that the Project Gutenberg-tm collection will
remain freely available for generations to come. In 2001, the Project
Gutenberg Literary Archive Foundation was created to provide a secure
and permanent future for Project Gutenberg-tm and future generations.

Section 4. Information about Donations to the Project Gutenberg
Literary Archive Foundation
Project Gutenberg-tm depends upon and cannot survive without wide
spread public support and donations to carry out its mission of
increasing the number of public domain and licensed works that can be
freely distributed in machine readable form accessible by the widest
array of equipment including outdated equipment. Many small donations
($1 to $5,000) are particularly important to maintaining tax exempt
status with the IRS.
The Foundation is committed to complying with the laws regulating
charities and charitable donations in all 50 states of the United
States. Compliance requirements are not uniform and it takes a
considerable effort, much paperwork and many fees to meet and keep up
with these requirements. We do not solicit donations in locations
where we have not received written confirmation of compliance. To
SEND DONATIONS or determine the status of compliance for any
particular state visit http://pglaf.org
While we cannot and do not solicit contributions from states where we
have not met the solicitation requirements, we know of no prohibition
against accepting unsolicited donations from donors in such states who
approach us with offers to donate.
International donations are gratefully accepted, but we cannot make
any statements concerning tax treatment of donations received from
outside the United States. U.S. laws alone swamp our small staff.
Please check the Project Gutenberg Web pages for current donation
methods and addresses. Donations are accepted in a number of other
ways including checks, online payments and credit card donations.

Section 5. General Information About Project Gutenberg-tm electronic
works.
Professor Michael S. Hart is the originator of the Project Gutenberg-tm
concept of a library of electronic works that could be freely shared
with anyone. For thirty years, he produced and distributed Project
Gutenberg-tm eBooks with only a loose network of volunteer support.
Project Gutenberg-tm eBooks are often created from several printed
editions, all of which are confirmed as Public Domain in the U.S.
unless a copyright notice is included. Thus, we do not necessarily
keep eBooks in compliance with any particular paper edition.
Most people start at our Web site which has the main PG search facility:
http://www.gutenberg.org
This Web site includes information about Project Gutenberg-tm,
including how to make donations to the Project Gutenberg Literary
Archive Foundation, how to help produce our new eBooks, and how to
subscribe to our email newsletter to hear about new eBooks.
