Hudson lay in his sleeping bag, staring at the sky. It bothered
him a lot. There was not one familiar constellation, not one star
that he could name with any certainty. This juggling of the stars,
he thought, emphasized more than anything else in this ancient
land the vast gulf of years which lay between him and the Earth
where he had been--or would be--born.
A hundred and fifty thousand years, Adams had said, give or take
ten thousand. There just was no way to know. Later on, there might
be. A measurement of the stars and a comparison with their
positions in the twentieth century might be one way of doing it.
But at the moment, any figure could be no more than a guess.
The time machine was not something that could be tested for
calibration or performance. As a matter of fact, there _was_ no
way to test it. They had not been certain, he remembered, the
first time they had used it, that it would really work. There had
been no way to find out. When it worked, you knew it worked. And
if it hadn't worked, there would have been no way of knowing
beforehand that it wouldn't.
Adams had been sure, of course, but that had been because he had
absolute reliance in the half-mathematical, half-philosophic
concepts he had worked out--concepts that neither Hudson nor
Cooper could come close to understanding.
That had always been the way it had been, even when they were
kids, with Wes dreaming up the deals that he and Johnny carried
out. Back in those days, too, they had used time travel in their
play. Out in Johnny's back yard, they had rigged up a time
machine out of a wonderful collection of salvaged junk--a wooden
crate, an empty five-gallon paint pail, a battered coffee maker, a
bunch of discarded copper tubing, a busted steering wheel and
other odds and ends. In it, they had "traveled" back to
Indian-before-the-white-man land and mammoth-land and
dinosaur-land and the slaughter, he remembered, had been
wonderfully appalling.
But, in reality, it had been much different. There was much more
to it than gunning down the weird fauna that one found.
And they should have known there would be, for they had talked
about it often.
He thought of the bull session back in university and the little,
usually silent kid who sat quietly in the corner, a law-school
student whose last name had been Pritchard.
And after sitting silently for some time, this Pritchard kid had
spoken up: "If you guys ever do travel in time, you'll run up
against more than you bargain for. I don't mean the climate or the
terrain or the fauna, but the economics and the politics."
They all peered at him, Hudson remembered, and then had gone on
with their talk. And after a short while, the talk had turned to
women, as it always did.
He wondered where that quiet man might be. Some day, Hudson told
himself, I'll have to look him up and tell him he was right.
We did it wrong, he thought. There were so many other ways we
might have done it, but we'd been so sure and greedy--greedy for
the triumph and the glory--and now there was no easy way to
collect.
On the verge of success, they could have sought out help, gone to
some large industrial concern or an educational foundation or even
to the government. Like historic explorers, they could have
obtained subsidization and sponsorship. Then they would have had
protection, funds to do a proper job and they need not have
operated on their present shoestring--one beaten-up helicopter and
one time unit. They could have had several and at least one
standing by in the twentieth century as a rescue unit, should that
be necessary.
But that would have meant a bargain, perhaps a very hard one, and
sharing with someone who had contributed nothing but the money.
And there was more than money in a thing like this--there were
twenty years of dreams and a great idea and the dedication to
that great idea--years of work and years of disappointment and an
almost fanatical refusal to give up.
Even so, thought Hudson, they had figured well enough. There had
been many chances to make blunders and they'd made relatively few.
All they lacked, in the last analysis, was backing.
Take the helicopter, for example. It was the one satisfactory
vehicle for time traveling. You had to get up in the air to clear
whatever upheavals and subsidences there had been through geologic
ages. The helicopter took you up and kept you clear and gave you a
chance to pick a proper landing place. Travel without it and,
granting you were lucky with land surfaces, you still might
materialize in the heart of some great tree or end up in a swamp
or the middle of a herd of startled, savage beasts. A plane would
have done as well, but back in this world, you couldn't land a
plane--or you couldn't be certain that you could. A helicopter,
though, could land almost anywhere.
In the time-distance they had traveled, they almost certainly had
been lucky, although one could not be entirely sure just how great
a part of it was luck. Wes had felt that he had not been working
as blindly as it sometimes might appear. He had calibrated the
unit for jumps of 50,000 years. Finer calibration, he had said
realistically, would have to wait for more developmental work.
Using the 50,000-year calibrations, they had figured it out. One
jump (conceding that the calibration was correct) would have
landed them at the end of the Wisconsin glacial period; two jumps,
at its beginning. The third would set them down toward the end of
the Sangamon Interglacial and apparently it had--give or take ten
thousand years or so.
They had arrived at a time when the climate did not seem to vary
greatly, either hot or cold. The flora was modern enough to give
them a homelike feeling. The fauna, modern and Pleistocenic,
overlapped. And the surface features were little altered from the
twentieth century. The rivers ran along familiar paths, the hills
and bluffs looked much the same. In this corner of the Earth, at
least, 150,000 years had not changed things greatly.
Boyhood dreams, Hudson thought, were wondrous. It was not often
that three men who had daydreamed in their youth could follow it
out to its end. But they had and here they were.
Johnny was on watch, and it was Hudson's turn next, and he'd
better get to sleep. He closed his eyes, then opened them again
for another look at the unfamiliar stars. The east, he saw, was
flushed with silver light. Soon the Moon would rise, which was
good. A man could keep a better watch when the Moon was up.
He woke suddenly, snatched upright and into full awareness by the
marrow-chilling clamor that slashed across the night. The very air
seemed curdled by the savage racket and, for a moment, he sat
numbed by it. Then, slowly, it seemed--his brain took the noise
and separated it into two distinct but intermingled categories,
the deadly screaming of a cat and the maddened trumpeting of a
mastodon.
The Moon was up and the countryside was flooded by its light.
Cooper, he saw, was out beyond the watchfires, standing there and
watching, with his rifle ready. Adams was scrambling out of his
sleeping bag, swearing softly to himself. The cooking fire had
burned down to a bed of mottled coals, but the watchfires still
were burning and the helicopter, parked within their circle,
picked up the glint of flames.
"It's Buster," Adams told him angrily. "I'd know that bellowing of
his anywhere. He's done nothing but parade up and down and bellow
ever since we got here. And now he seems to have gone out and
found himself a saber-tooth."
Hudson zipped down his sleeping bag, grabbed up his rifle and
jumped to his feet, following Adams in a silent rush to where
Cooper stood.
Cooper motioned at them. "Don't break it up. You'll never see the
like of it again."
Adams brought his rifle up.
Cooper knocked the barrel down.
"You fool!" he shouted. "You want them turning on us?"
Two hundred yards away stood the mastodon and, on his back, the
screeching saber-tooth. The great beast reared into the air and
came down with a jolt, bucking to unseat the cat, flailing the air
with his massive trunk. And as he bucked, the cat struck and
struck again with his gleaming teeth, aiming for the spine.
Then the mastodon crashed head downward, as if to turn a
somersault, rolled and was on his feet again, closer to them now
than he had been before. The huge cat had sprung off.
For a moment, the two stood facing one another. Then the tiger
charged, a flowing streak of motion in the moonlight. Buster
wheeled away and the cat, leaping, hit his shoulder, clawed wildly
and slid off. The mastodon whipped to the attack, tusks slashing,
huge feet stamping. The cat, caught a glancing blow by one of the
tusks, screamed and leaped up, to land in spread-eagle fashion
upon Buster's head.
Maddened with pain and fright, blinded by the tiger's raking
claws, the old mastodon ran--straight toward the camp. And as he
ran, he grasped the cat in his trunk and tore him from his hold,
lifted him high and threw him.
"Look out!" yelled Cooper and brought his rifle up and fired.
For an instant, Hudson saw it all as if it were a single scene,
motionless, one frame snatched from a fantastic movie epic--the
charging mastodon, with the tiger lifted and the sound track one
great blast of bloodthirsty bedlam.
Then the scene dissolved in a blur of motion. He felt his rifle
thud against his shoulder, knowing he had fired, but not hearing
the explosion. And the mastodon was almost on top of him, bearing
down like some mighty and remorseless engine of blind destruction.
He flung himself to one side and the giant brushed past him. Out
of the tail of his eye, he saw the thrown saber-tooth crash to
Earth within the circle of the watchfires.
He brought his rifle up again and caught the area behind Buster's
ear within his sights. He pressed the trigger. The mastodon
staggered, then regained his stride and went rushing on. He hit
one of the watchfires dead center and went through it, scattering
coals and burning brands.
Then there was a thud and the screeching clang of metal.
"Oh, no!" shouted Hudson.
Rushing forward, they stopped inside the circle of the fires.
The helicopter lay tilted at a crazy angle. One of its rotor
blades was crumpled. Half across it, as if he might have fallen as
he tried to bull his mad way over it, lay the mastodon.
Something crawled across the ground toward them, its spitting,
snarling mouth gaping in the firelight, its back broken, hind legs
trailing.
Calmly, without a word, Adams put a bullet into the head of the
saber-tooth.

General Leslie Bowers rose from his chair and paced up and down
the room. He stopped to bang the conference table with a knotted
fist.
"You can't do it," he bawled at them. "You can't kill the project.
I _know_ there's something to it. We can't give it up!"
"But it's been ten years, General," said the secretary of the
army. "If they were coming back, they'd be here by now."
The general stopped his pacing, stiffened. Who did that little
civilian squirt think he was, talking to the military in that tone
of voice!
"We know how you feel about it, General," said the chairman of the
joint chiefs of staff. "I think we all recognize how deeply you're
involved. You've blamed yourself all these years and there is no
need of it. After all, there may be nothing to it."
"Sir," said the general, "I _know_ there's something to it. I
thought so at the time, even when no one else did. And what we've
turned up since serves to bear me out. Let's take a look at these
three men of ours. We knew almost nothing of them at the time, but
we know them now. I've traced out their lives from the time that
they were born until they disappeared--and I might add that, on
the chance it might be all a hoax, we've searched for them for
years and we've found no trace at all.
"I've talked with those who knew them and I've studied their
scholastic and military records. I've arrived at the conclusion
that if any three men could do it, they were the ones who could.
Adams was the brains and the other two were the ones who carried
out the things that he dreamed up. Cooper was a bulldog sort of
man who could keep them going and it would be Hudson who would
figure out the angles.
"And they knew the angles, gentlemen. They had it all doped out.
"What Hudson tried here in Washington is substantial proof of
that. But even back in school, they were thinking of those angles.
I talked some years ago to a lawyer in New York, name of
Pritchard. He told me that even back in university, they talked
of the economic and political problems that they might face if
they ever cracked what they were working at.
"Wesley Adams was one of our brightest young scientific men. His
record at the university and his war work bears that out. After
the war, there were at least a dozen jobs he could have had. But
he wasn't interested. And I'll tell you why he wasn't. He had
something bigger--something he wanted to work on. So he and these
two others went off by themselves--"
"You think he was working on a temporal--" the army secretary cut
in.
"He was working on a time machine," roared the general. "I don't
know about this 'temporal' business. Just plain 'time machine' is
good enough for me."
"Let's calm down, General," said the JCS chairman, "After all,
there's no need to shout."
The general nodded. "I'm sorry, sir. I get all worked up about
this. I've spent the last ten years with it. As you say, I'm
trying to make up for what I failed to do ten years ago. I should
have talked to Hudson. I was busy, sure, but not that busy. It's
an official state of mind that we're too busy to see anyone and I
plead guilty on that score. And now that you're talking about
closing the project--"
"It's costing us money," said the army secretary.
"And we have no direct evidence," pointed out the JCS chairman.
"I don't know what you want," snapped the general. "If there was
any man alive who could crack time, that man was Wesley Adams. We
found where he worked. We found the workshop and we talked to
neighbors who said there was something funny going on and--"
"But ten years, General!" the army secretary protested.
"Hudson came here, bringing us the greatest discovery in all
history, and we kicked him out. After that, do you expect them to
come crawling back to us?"
"You think they went to someone else?"
"They wouldn't do that. They know what the thing they have found
would mean. They wouldn't sell us out."
"Hudson came with a preposterous proposition," said the man from
the state department.
"They had to protect themselves!" yelled the general. "If you had
discovered a virgin planet with its natural resources intact, what
would you do about it? Come trotting down here and hand it over to
a government that's too 'busy' to recognize--"
"General!"
"Yes, sir," apologized the general tiredly. "I wish you gentlemen
could see my view of it, how it all fits together. First there
were the films and we have the word of a dozen competent
paleontologists that it's impossible to fake anything as perfect
as those films. But even granting that they could be, there are
certain differences that no one would ever think of faking,
because no one ever knew. Who, as an example, would put lynx
tassels on the ears of a saber-tooth? Who would know that young
mastodon were black?
"And the location. I wonder if you've forgotten that we tracked
down the location of Adams' workshop from those films alone. They
gave us clues so positive that we didn't even hesitate--we drove
straight to the old deserted farm where Adams and his friends had
worked. Don't you see how it all fits together?"
"I presume," the man from the state department said nastily, "that
you even have an explanation as to why they chose that particular
location."
"You thought you had me there," said the general, "but I have an
answer. A good one. The southwestern corner of Wisconsin is a
geologic curiosity. It was missed by all the glaciations. Why, we
do not know. Whatever the reason, the glaciers came down on both
sides of it and far to the south of it and left it standing there,
a little island in a sea of ice.
"And another thing: Except for a time in the Triassic, that same
area of Wisconsin has always been dry land. That and a few other
spots are the only areas in North America which have not, time and
time again, been covered by water. I don't think it necessary to
point out the comfort it would be to an experimental traveler in
time to be certain that, in almost any era he might hit, he'd have
dry land beneath him."
The economics expert spoke up: "We've given this matter a lot of
study and, while we do not feel ourselves competent to rule upon
the possibility or impossibility of time travel, there are some
observations I should like, at some time, to make."
"Go ahead right now," said the JCS chairman.
"We see one objection to the entire matter. One of the reasons,
naturally, that we had some interest in it is that, if true, it
would give us an entire new planet to exploit, perhaps more wisely
than we've done in the past. But the thought occurs that any
planet has only a certain grand total of natural resources. If we
go into the past and exploit them, what effect will that have upon
what is left of those resources for use in the present? Wouldn't
we, in doing this, be robbing ourselves of our own heritage?"
"That contention," said the AEC chairman, "wouldn't hold true in
every case. Quite the reverse, in fact. We know that there was, in
some geologic ages in the past, a great deal more uranium than we
have today. Go back far enough and you'd catch that uranium before
it turned into lead. In southwestern Wisconsin, there is a lot of
lead. Hudson told us he knew the location of vast uranium deposits
and we thought he was a crackpot talking through his hat. If we'd
known--let's be fair about this--if we had known and believed him
about going back in time, we'd have snapped him up at once and all
this would not have happened."
"It wouldn't hold true with forests, either," said the chairman of
the JCS. "Or with pastures or with crops."
The economics expert was slightly flushed. "There is another
thing," he said. "If we go back in time and colonize the land we
find there, what would happen when that--well, let's call it
retroactive--when that retroactive civilization reaches the
beginning of our historic period? What will result from that
cultural collision? Will our history change? Is what has happened
false? Is all--"
"That's all poppycock!" the general shouted. "That and this other
talk about using up resources. Whatever we did in the past--or are
about to do--has been done already. I've lain awake nights,
mister, thinking about all these things and there is no answer,
believe me, except the one I give you. The question which faces us
here is an immediate one. Do we give all this up or do we keep on
watching that Wisconsin farm, waiting for them to come back? Do we
keep on trying to find, independently, the process or formula or
method that Adams found for traveling in time?"
"We've had no luck in our research so far, General," said the
quiet physicist who sat at the table's end. "If you were not so
sure and if the evidence were not so convincing that it had been
done by Adams, I'd say flatly that it is impossible. We have no
approach which holds any hope at all. What we've done so far, you
might best describe as flounder. But if Adams turned the trick, it
must be possible. There may be, as a matter of fact, more ways
than one. We'd like to keep on trying."
"Not one word of blame has been put on you for your failure," the
chairman told the physicist. "That you could do it seems to be
more than can be humanly expected. If Adams did it--_if_ he did, I
say--it must have been simply that he blundered on an avenue of
research no other man has thought of."
"You will recall," said the general, "that the research program,
even from the first, was thought of strictly as a gamble. Our one
hope was, and must remain, that they will return."
"It would have been so much simpler all around," the state
department man said, "if Adams had patented his method."
The general raged at him. "And had it published, all neat and
orderly, in the patent office records so that anyone who wanted it
could look it up and have it?"
"We can be most sincerely thankful," said the chairman, "that he
did not patent it."
