 Why does the Sand God keep the webfoots around?
The sand-thing was powerful, lonely and strange. 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. 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. 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? 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. 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. These are the undesirables, the incorrigibles, the nonconformists from the sixth planet.
 It amuses the Sand God to watch the webfoots evolution.
 It amuses the Sand God to watch the webfoots evolution.  It amuses the Sand God to play with the webfoots.  The webfoots worship him like a God even though he is not one.  The webfoots fear of the Sand God amuses him.
