From across the handful of flames Ashe's eyes, too bright in a fever-flushed face, watched him demandingly. The fugitives had taken cover in an angle where the massed remains of an old avalanche provided a cave-pocket. McNeil was off scouting in the gray drizzle of the day, and their escape from the village was now some forty-eight hours behind them. "So the crackpots were right, after all. They only had their times mixed." Ashe shifted on the bed of brush and leaves they had raked together for his comfort. "I don't understand----" "Flying saucers," Ashe returned with an odd little laugh. "It was a wild possibility, but it was on the books from the start. This certainly will make Kelgarries turn red----" "Flying saucers?" Ashe must be out of his head from the fever, Ross supposed. He wondered what he should do if Ashe tried to get up and walk away. He could not tackle a man with a bad hole in his shoulder, nor was he certain he could wrestle Ashe down in a real fight. "That globe-ship was never built on this world. Use your head, Murdock. Think about your furry-faced friend and the baldy with him. Did either look like normal Terrans to you?" "But--a spaceship!" It was something that had so long been laughed to scorn. When men had failed to break into space after the initial excitement of the satellite launchings, space flight had become a matter for jeers. On the other hand, there was the evidence collected by his own eyes and ears, his own experience. The services of the lifeboat had been techniques outside of his experience. "This was insinuated once"--Ashe was lying flat now, gazing speculatively up at the projection of logs and earth which made them a partial roof--"along with a lot of other bright ideas, by a gentleman named Charles Fort, who took a lot of pleasure in pricking what he considered to be vastly over-inflated scientific pomposity. He gathered together four book loads of reported incidents of unexplainable happenings which he dared the scientists of his day to explain. And one of his bright suggestions was that such phenomena as the vast artificial earthworks found in Ohio and Indiana were originally thrown up by space castaways to serve as S O S signals. An intriguing idea, and now perhaps we may prove it true." "But if such spaceships were wrecked on this world, I still don't see why we didn't find traces of them in our own time." "Because that wreck you explored was bedded in a glacial era. Do you have any idea how long ago that was, counting from our own time? There were at least three glacial periods--and we don't know in which one the Reds went visiting. That age began about a million years before we were born, and the last of the ice ebbed out of New York State some thirty-eight thousand years ago, boy. That was the early Stone Age, reckoning it by the scale of human development, with an extremely thin population of the first real types of man clinging to a few warmer fringes of wilderness.
