Joe stood in all his glory at what Potts called the P. T. machine. The apparatus was a marble box with rows of knobs and gauges and a pair of rubber hoses on the top. Potts felt sure that Joe took a sadistic delight in his work. As the line moved forward, he glanced at the attendant's florid face, tight smiling lips and squinted eyes. Potts shuddered. No member of the hospital staff had ever condescended to explain to Potts the exact purpose of the P. T. bath, other than that it would make him feel good. It only frightened Potts. The correct procedure was that the patient stepped between the pipes of the needle shower and washed himself. Then the attendant turned off the shower and sluiced the patient with powerful streams of water from the hoses. The routine seemed senseless and innocent enough, but Potts had heard whispered conversations in the night that filled him with horror. The P. T. machine, rumor said, was actually an instrument of torture and death. The water pressure could be increased to two thousand pounds, enough to push out a man's eyes or break his bones. Instead of water, the hoses could spit fire like a flamethrower. Acid could spray from the shower. Potts had even heard that Joe had killed seven men in the P. T. bath. How much of this was true, Potts did not know. When he saw bodies turn suddenly red under a rain of hot water, or writhe and tremble as if being whipped, he could believe all of it. The line advanced slowly, like a gang of criminals going to the gas chamber. Potts grimly determined to think himself out of the hospital at once, for who knew when fire instead of water would spout from the hoses? If he recalled some place outside, in exact detail, Potts knew he could become all mind and project himself there. He must recall everything, scents, temperature, the ground beneath his feet, precise colors. Potts concentrated. He tried to remember the home he had not seen for three months. He received a dim impression of a tiny crowded apartment and a wife growing increasingly indifferent. He could not even remember the color of her eyes, or whether the living room contained one easy chair or two. He would have to project himself to another place, one that did not seem like a vague dream. Potts saw that his bath would come next. Danny Harris stood in the spray and stared stupidly at the tile floor. Potts looked at Joe. A wide smile that revealed two gold teeth creased the burly attendant's face. Hairy hands turned off the needle shower, twisted two more knobs, and picked up the twin hoses. Joe stood like the villain in a Western movie, blazing away with two guns, and shot thin powerful streams of water against Harris's spine. Harris shrieked, though he rarely uttered a sound outside the P. T. bath. As the icy water raked him from head to heels, he yelled and danced. "Turn around," Joe commanded.
