A tourist came in from Orbitville, parked in the air, and said: The creatures of this star are made of metal and glass. Through the transparent parts 5 you can see their guts. Their feet are round and roll on diagrams or long measuring tapes, dark with white lines. 10 They have four eyes. The two in the back are red. Sometimes you can see a five-eyed one, with a red eye turning on the top of his head. 15 He must be special— the others respect him, and go slow when he passes, winding among them from behind. 20 They all hiss as they glide, like inches, down the marked tapes. Those soft shapes, shadowy inside the hard bodies—are they 25 their guts or their brains?
