other planets may have followed an entirely different line than on Earth? This may be the case, and, knowing the tendency of humans to dislike anything different from themselves, the natives may have wisely decided to stay in hiding for the time being." "Whatever they are," said David Hellman, who had been listening, "they are certainly more advanced than we, so any contact should be to our advantage." "If our hosts ever decide that they want anything to do with us," Clyde Ellery said dryly. He waved ahead of them as they stepped to the ground. "And they apparently don't as yet." Ahead of them stretched the broad, flat continent. With two exceptions, all there was to see was rich-looking, bare soil. There was a looseness to the dirt which made it seem that not so long ago it had been cultivated, but now there was not so much as a blade of grass. The bareness of the black earth made the exceptions even more noticeable. Not far from where their ship was grounded, there were two rows of trees, about the width of an Earth city street apart. The trees were towering, half again as tall as the giant redwoods of Earth. The leaves, a delicate pink in color, were broad and oval, curling at the edges to form almost a perfect ball. These hung down from the limbs, swaying toward the ground. From each rounded leaf there were two waving tendrils, looking almost like antennae, ranging from a deep pink at the base to a light purple at their tips. Back of where the ship had grounded, there was a rounded, dome-like structure, large enough to house several hundred of the ships. Green in color, it seemed to be built of broad, flat leaves. Around it were a number of trees, their limbs twisting far above the building. Their leaves were long and tapering, a deep orange in color, while the trunk and limbs were dark green. From each limb hung dozens of pods, fully three feet long and a foot thick at the center, tapering to an end which seemed to have an opening three or four inches in diameter. For the rest, there was only rich dark soil for almost as far as the eye could see. At a distance, where the curve of land met the sky, they could see the edge of what appeared to be almost a jungle. But, except for the tree leaves moving restlessly in the slight breeze, there was no movement, no sound. Within the hour the other ships began arriving, in groups of two and three. First to land were those which had been loaded with material. As the passenger ships landed, the men were divided into two groups. One was set to putting up
