But Louie was in no mood for banter. He wished Tom would go back and hold the manual controls of the ship instead of letting it hover on automatic. He wished Cal would go back to his stateroom and think. He wished Frank Norton would shut up. He wished they wouldn't all stand over him, reading his charts over his shoulder.

In irritated silence he reduced the viewscope dimensions to scale, and snapped a picture of the whole island. He took the fresh picture, still moist from its self-developing camera, and laid it beside the chart. Wordlessly, for the benefit of them all, he traced his pencil over the outlines of the chart and their duplicates in the picture. As in comparing fingerprints, he flicked his pencil at the points of identity. There were far too many to ignore. He poked the point of his pencil at Appletree where it was located on the chart. Then he picked out the same location in the picture.

It was not the science of navigation that was wrong.

"It's just one of those dirty tricks life plays on a fellow," Tom said over Cal's shoulder. "You got us in the right place, Louie, but probably in the wrong time slot. You've warped us right out of our own time, and Eden hasn't been discovered yet. Maybe won't be for another million years. Maybe, back on Earth, man is just discovering fire."

"Yeah," Norton agreed. "Or maybe in the wrong dimension. You and your fancy navigation. Now you take a midgit-idgit navigating machine. It wouldn't know how to pull such fancy short cuts. Take a little longer, maybe, but when we got there we'd be there."

They were both talking nonsense and knew it. Time and dimensional travel were still purely theoretical. Louie ignored the ribbing with elaborate patience.

"You know what I think," he asked seriously. "I think the whole thing's a hoax. I'll betcha there never was any settlement there. I'll betcha the colonists have pulled a whingding all the way through."

"There's a whole raft of pictures to show they were there," Frank reminded him.

"Pictures!" Louie answered scornfully. "You think they couldn't fake pictures?" He thought for a moment. "And where's their ship, their escape ship?" he asked as a clincher. "They didn't like it here and have gone off somewhere else, and then covered up by sending reports and pictures on how things would have developed if they'd stayed."

There was a sense of unreality in the whole conversation. Cal let the talk flow on, knowing it was a reaction to shock. What if a modern ocean liner pulled into the harbor of New York—to find an untouched Manhattan Island in its virgin state?
