Kitty said didactically, "then Man has not evolved on New Earth." Since it was spoken in the tone of an axiom, and there was no evidence to refute it, neither of the two men felt like arguing the matter. They were low enough now that they were flying horizontally rather than dropping vertically. They were still searching for traces of some kind of artifacts. They were also searching, Lt. Harper advised them at last, for a suitable place to land. They wanted a higher ground than the delta country so they might be free of insect pests, assuming there were some since deer could be seen throwing their heads back along their sides as if to chase away flies. They wanted higher ground with a stream of water going over falls to supplement their limited power in the lifeship. On the chance there were fish, it would be nice to be handy to a lake.

He threw down the hinged metal steps. He stood back. Miss Kitty went through the door first and down the steps. The two men followed. They stood on the ground of New Earth, and looked at one another the way they had in the ship. In the minds of each there was the thought that some kind of a ceremonial speech should be made, but no one volunteered it. "I suppose we should have a campfire," Miss Kitty said doubtfully. They did not realize it at the time, but it was the most effective speech which could have been devised. It was a symbol. Man had discovered and taken possession of New Earth. His instinctive thought was to place his brand upon it, an artificial fire. All of them missed the significance of the fact that it was Miss Kitty who had made the first move in the domestication of this New Earth. In the weeks which followed, Miss Kitty began to be dimly aware of the significance. At first they had
