It talked or sometim es yelled through its ventilators, too. In went water and loaves of blackbread and sausage and cheese, and out came shit and piss and language. Human beings in there were excreting into steel helmets, which were passed to the people at the ventilators, who dumped them. Billy was a dumper. The human beings also passed canteens, which guards would fill with water. When food came in, the human beings were quiet and trusting and beautiful. They shared. Human beings in there took turns standing or lying down. The legs of those who stood were like fence posts driven into a warm ., squirming, fatting, sighing earth. The queer earth was a mosaic of sleepers who nestled like spoons. Now the train began to creep eastward. Somewhere in there was Christmas. Billy Pilgrim nestled like a spoon with the hobo on Christmas night, and he fell asleep, and he traveled in time to 1967 againto the night he was kidnapped by a flying saucer from Tralfamadore. Four Billy Pilgrim could not sleep on his daughters wedding night. He was forty four. The wedding had taken place that afternoon in a gaily striped tent in Billy39。s backyard. The stripes were orange and black. Billy and his wife, Valencia, nestled like spoons in their big double bed. They were jiggled by Magic Fingers. Valencia didn39。 t need to be jiggled to sleep. Valencia was snoring like a bandsaw. T he poor woman didn39。t have ovaries or a uterus any more. They had been removed by a surgeonby one of Billy39。s partners in the New Holiday Inn. There was a full moon. Billy got out of bed in the moonlight. He felt spooky and luminous felt as though he were wrapped in cool fur that was full of static electricity. He looked down at his bare feet. They were ivory and blue. Billy now shuffled down his upstairs hallway, knowing he was about to be kidnapped by a flying saucer. The hallway was zebra striped with darkness and moonlight. The moonlight came into the hallway through doorways of the empty rooms of Billy39。s two children, children no more. They were gone forever. Billy was guided by dread and the lack of dread. Dread told him when to stop. Lack of it told him when to move again. He stopped. He went into his daughter39。s room. Her drawers were dumped. her closet was empty. Heaped in the middle of the room were all the possessions she could not take on a honeymoon. She had a Princess telephone extension all her ownon her windowsill Its tiny night light stared at Billy. And then it rang. Billy answered. There was a drunk on the other end. Bi 39。Who killed me? he would ask. And everybody knew the answer., which was this: Billy Pilgrim.39。 Listen on the tenth night the peg was pulled out of the hasp on Billy39。s boxcar door, and the door was opened. Billy Pilgrim was lying at an angle on the cornerbrace, selfcrucified, holding himself there with a blue and ivory claw hooked over the sill of the ventilator. Billy coughed when the door was opened, and when he coughed he shit thin gruel. This was in accordance with the Third Law of Motion according to Sir Isaac Newton. This law tells us that for every action there is a reaction which is equal and opposite in direction. This can be useful in rocketry. The train had arrived on a siding by a prison which was originally constructed as an extermination camp for Russian prisoners of war. The guards peeked inside Billy39。s car owlishly, cooed calmingly. They had never dealt w ith Americans before, but they surely understood this general sort of freight. They knew that it was esse ntially a liquid which could be induced to flow slowly toward cooing and light. It was nighttime. The only light outside came from a single bulb which hung from a polehigh and far away. All was quiet outside, except for the guards, who cooed like doves. And the liquid began to flow. Gobs of it built up in the doorway, plopped to the ground. Billy was the nexttolast human being to reach the door. The hobo was the last. The hobo could not flow, could not plop. He wasn39。t liquid any more. He was stone. So it goes. Billy didn39。t. want to drop from the car to the ground. He sincerely believed that he would shatter like glass. So the guards helped him down, cooing still. T hey set him down facing the train. I t was such a dinky train now. There was a lootive, a tender, and three little boxcars. The last boxcar was the railroad guards39。 heaven on wheels. Againin
