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."

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."
