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, bringi
ng 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."

The helicopter would never fly again, but the time unit was intact.
Which didn't mean that it would work.
They held a powwow at their camp site. It had been, they decided, simpler to move the camp than to remove the body of Old Buster. So they had shifted at dawn, leaving the old mastodon still sprawled across the helicopter.
In a day or two, they knew, the great bones would be cleanly picked by the carrion birds, the lesser cats, the wolves and foxes and the little skulkers.
Getting the time unit out of the helicopter had been quite a chore, but they finally had managed and now Adams sat with it cradled in his lap.
"The worst of it," he told them, "is that I can't test it. There's no way to. You turn it on and it works or it doesn't work. You can't know till you try."
"That's something we can't help," Cooper replied. "The problem, seems to me, is how we're going to use it without the whirlybird."
"We have to figure out some way to get up in the air," said Adams. "We don't want to take the chance of going up into the twentieth century and arriving there about six feet underground."
"Common sense says that we should be higher here than up ahead," Hudson pointed out. "These hills have stood here since Jurassic times. They probably were a good deal higher then and have weathered down. That weathering still should be going on. So we should be higher here than in the twentieth century--not much, perhaps, but higher."
"Did anyone ever notice what the altimeter read?" asked Cooper.
"I don't believe I did," Adams admitted.
"It wouldn't tell you, anyhow," Hudson declared. "It would just give our height then and now--and we were moving, remember--and what about air pockets and relative atmosphere density and all the rest?"
Cooper looked as discouraged as Hudson felt.
"How does this sound?" asked Adams. "We'll build a platform twelve feet high. That certainly should be enough to clear us and yet small enough to stay within the range of the unit's force-field."
"And what if we're two feet higher here?" Hudson pointed out.
"A fall of fourteen feet wouldn't kill a man unless he's plain unlucky."
"It might break some bones."
"So it might break some bones. You want to stay here or take a chance on a broken leg?"
"All right, if you put it that way. A platform, you say. A platform out of what?"
"Timber. There's lot of it. We just go out and cut some logs."
"A twelve-foot log is heavy. And how are we going to get that big a log uphill?"
"We drag it."
"We try to, you mean."
"Maybe we could fix up a cart," said Adams, after thinking a moment.
"Out of what?" Cooper asked.
"Rollers, maybe. We could cut some and roll the logs up here."
"That would work on level ground," Hudson said. "It wouldn't work to roll a log uphill. It would get away from us. Someone might get killed."
"The logs would have to be longer than twelve feet, anyhow," Cooper put in. "You'd have to set them in a hole and that takes away some footage."
"Why not the tripod principle?" Hudson offered. "Fasten three logs at the top and raise them."
"That's a gin-pole, a primitive derrick. It'd still have to be longer than twelve feet. Fifteen, sixteen, maybe. And how are we going to hoist three sixteen-foot logs? We'd need a block and tackle."
"There's another thing," said Cooper. "Part of those logs might just be beyond the effective range of the force-field. Part of them would have to--have to, mind you--move in time and part couldn't. That would set up a stress...."
"Another thing about it," added Hudson, "is that we'd travel with the logs. I don't want to come out in another time with a bunch of logs flying all around me."
"Cheer up," Adams told them. "Maybe the unit won't work, anyhow."

The general sat alone in his office and held his head between his hands. The fools, he thought, the goddam knuckle-headed fools! Why couldn't they see it as clearly as he did?
