 Why are the webfoots chasing Stinson and Sybtl?
Stinson lay still in the sand where he fell, gloating over the success of his arrival. He touched the pencil-line scar behind his ear where the cylinder was buried, marveling at the power stored there, power to fling him from earth to this fourth planet of the Centaurian system in an instant. It had happened so fast that he could almost feel the warm, humid Missouri air, though he was light years from Missouri. A gray, funnel-shaped cloud of dust stood off to his left. Weather control made cyclones and other climatic phenomena on earth practically non-existent. The cloud did not move, though, except to spin on its axis rapidly, emitting a high-pitched, scarcely audible whine, like a high speed motor. Dark clouds capped one peak of the mountains on his left. He was here and Earth was somewhere up there. The sun burned fiercely, although he would have said it was about four o'clock in the afternoon, if this had been Earth. Not a tree, nor a bush, nor even a wisp of dry grass was in sight. The sun shone obliquely, throwing Stinson's shadow upon the sand. The wind devil also had a shadow, although the sun shone through it and the shadow was faint. Again Stinson felt the urge to run, or to use the cylinder to project himself somewhere else, but he said, "No!" very firmly to himself. He was here to investigate, to determine if this planet was capable of supporting life. But then, how could a group of loosely spaced grains of sand possibly have a nervous system? He became so absorbed in doing this that he failed to notice how the wind devil drew closer and closer, but when he inhaled the first grains of sand, the realization of what was happening dawned with a flash of fear. As he stood beside a small creek, a chill wind blew from the northwest. He wanted to cover himself with the long leaves he found, but they were dry and brittle, for here autumn had turned the leaves. From one angle they were animals, from another birds, from a third they were vaguely humanoid creatures, glowering at him with primitive ferocity. These creatures were not only humanoid, but definitely human, although more slight of build than earth people. All were dressed from the waist down only, in a shimmering skirt that sparkled as they moved. "My name is Stinson," he said, pointing to himself. He left the chains by his own method of travel, and reappeared behind the two men.
