In due time the basket was filled to overflowing and Sutter stood still, waiting. Once more the surrounding landscape underwent its change. After the whirling had ceased and the initial feeling of vertigo had passed Sutter carried the full basket back to the car and began the long drive home. As he drove he mused over what Travail would say when he saw these shells. Then on second thought, he decided not to show them to him. Travail was getting on his nerves. He had obviously lied about his interest in shells. On discussing the subject with him Sutter found he did not know the first thing about them. In fact, he regretted taking him in as a roommate. He was convinced that Travail's friendly good-fellowship attitude was just a pose, cloaking a so far mysterious motive. But it could be that Travail knew of the value of Sutter's shell collection. Yesterday a letter had come from the Federal Arts Museum offering five thousand credits for the lot, and while he had made no mention of the amount, Sutter had been foolish enough to tell Travail there had been an offer. "Are you going to sell?" Travail had asked. "Certainly not. They're worth five times the price they offered." "Are they really?" said Travail. "That makes my own collection seem worthless by comparison." Oh, Travail could be clever all right! Why else had he made no comment about the alien shells they both had seen on the television set, if he did know something of the value of shells? Arriving home, Sutter entered by the rear door and carried the basket of shells to his bedroom. There he took them out and one by one spread them on the table. He drew a goose-necked lamp down close and from the table drawer took out a powerful ato-magnifying glass. Then he selected one of the larger shells and began to examine it. * * * * * After a while he took a small keyhole saw which he kept for such purposes, and very carefully began to cut the shell into two equal portions. Once again he moved the ato-glass and began to study one of the sections. But the lamp was not very powerful, and insufficient for the tiny details. Sutter abruptly remembered the four-position lamp in the sitting room. He took the shell and the ato-glass and went to the front room, hoping that Travail was not there. To his relief he found the sitting room deserted. The television set stood silent in a corner and as he passed it Sutter switched it on, then crossed to the four-position lamp and turned it up full. For a second time he peered through the ato-glass long and intently. The bisected shell appeared to be a spinal univalve, resembling the familiar cephalopoda, _nautilus_, with thin septa dividing the many chambers. Behind him the Tanganyika TV swelled on, the screen presenting that same scene of the beach of shells. As it did so Sutter uttered a startled exclamation.
