 Which is the best description of the Sand God?
The sand-thing was powerful, lonely and strange. 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. A gray, funnel-shaped cloud of dust stood off to his left. He stood on a wide valley floor between two mountain ranges. He was here and Earth was somewhere up there. The funnel of sand had moved closer and while he watched it, it seemed to drift in the wind—although there was no wind. 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. He was here to investigate, to determine if this planet was capable of supporting life. He examined the wind devil as closely as he dared, but it was composed only of grains of sand. But then, how could a group of loosely spaced grains of sand possibly have a nervous system? When it changed to a cube he drew a square, a circle for a sphere, and so on. 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. The wide plaza between the pool and cavern wall was smooth as polished glass. 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. The men were dark-skinned, the women somewhat lighter, with long flowing hair, wide lips and a beauty that was utterly sensual. He pointed upward, described a large circle, then another smaller, and showed how Earth revolved around the sun. But up to now the tube and the chain was the only evidence of an advanced technology, unless the ancient inscriptions in the stone wall of the pool, and the statues lining the wall were evidences. There, at the cavern entrance, the wind devil writhed and undulated in a brilliant harmony of colors. One of the women came toward him, long golden hair flowing, firm breasts dipping slightly at each step. It came from the ceiling, the floor, the walls, the steaming pool. The God with fingers on his feet has decreed this."
