.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 jeered 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 [ Pobierz całość w formacie PDF ]
