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. Life? Intelligence? He examined the wind devil as closely as he dared, but it was composed only of grains of sand. There was no core, no central place you could point to and say, here is the brain, or the nervous system. But then, how could a group of loosely spaced grains of sand possibly have a nervous system? It was again going through its paces. Triangle, cube, rectangle, sphere. He watched, and when it became a triangle again, he smoothed a place in the sand and drew a triangle with his forefinger. When it changed to a cube he drew a square, a circle for a sphere, and so on. When the symbols were repeated he pointed to each in turn, excitement mounting. 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. Instantly he projected himself a thousand miles away. * * * * * Now he was in an area of profuse vegetation. It was twilight. 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. Night would be cold. He was not a woodsman. He doubted if he could build a fire without matches. So he followed the creek to where it flowed between two great hills. Steam vapors rose from a crevice. A cave was nearby and warm air flowed from its mouth. He went inside. At first he thought the cave was small, but found instead that he was in a long narrow passageway. The current of warm air flowed toward him and he followed it, cautiously, stepping carefully and slowly. Then it was not quite so dark. Soon he stepped out of the narrow passageway into a great cavern with a high-vaulted ceiling. The light source was a mystery. He left no shadow on the floor. A great crystal sphere hung from the ceiling, and he was curious about its purpose, but a great pool of steaming water in the center of the cavern drew his attention. He went close, to warm himself. A stone wall surrounding the pool was inscribed with intricate art work and indecipherable symbols. Life. Intelligence. The planet was inhabited. Should he give up and return to earth? Or was there room here for his people? Warming his hands there over the great steaming pool he thought of Benjamin, and Straus, and Jamieson--all those to whom he had given cylinders, and who were now struggling for life against those who desired them. He decided it would not be just, to give up so easily. The wide plaza between the pool and cavern wall was smooth as polished glass. Statues lined the wall. He examined them.
