【正文】 led 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 fortyfour. The wedding had taken place that afternoon in a gaily striped tent in 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 zebrastriped with darkness and moonlight. The moonlight came into the hallway through doorways of the empty rooms of Billy39。 Listen on the tenth night the peg was pull。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。t need to be jiggled to sleep. Valencia was snoring like a bandsaw.
