your little bits of blonde, empty-headed fluff to be protected by strong males! I should have been told immediately!" Lt. Harper looked at Sam with a broad grin. It was amusement, but it was more--a confirmation that they could depend on her to take it in her stride--an approval. Apparently, they had discussed more things about her than she'd overheard, while she slept. He didn't turn off the grin when he looked directly at her. "What could you have done about it, if we had told you, Miss Kitty?" he asked mildly. It was not the same Earth. The charts and maps had not been wrong. Her tentative theory that perhaps there were vision flaws in the plastic nose window which had not stood up. The continents, the lakes, the rivers--the topography really was distorted. Now there was the Mississippi River, one spot swinging rather too widely to the East. The Great Lakes were one huge inland sea. The Gulf of Mexico swung high up into what had once been Alabama and Georgia. There was no New Orleans, shipping center of the world, headquarters of Space. There were no cities anywhere up and down the Mississippi. Where St. Louis should have been, there was virgin forest. As they dropped down into the upper reaches of atmosphere, experiencing the familiar and sometimes nauseating reference shift from ahead to below, there had been no New York to the East, no San Francisco to the West. There had been no Boulder Dam, no Tennessee Valley project, no continuous hydroelectric installations running the entire length of the Mississippi, where the strength of the Father of the Waters had finally been harnessed for Man. There were no thin lines of highways, no paint-brush strokes of smoke against the canvas of the Gulf of Mexico to denote steamers, for atomic power was still not available to all. On this New Earth, Man could not yet have reached a state of complex technology.

They saw no huts along the river shore, no thin streamers of wood smoke from huts hidden under the trees along the bayous. New Earth was purple and blue, then shading into green as they dropped lower. They sighted a deer drinking at the edge of a pool. But there was no trace of Man. "If there are no scars, no defacements upon this forest primeval," Miss
