They looked at the other American bodies now, pointed out a lot more that were nearly as bad as Billy39。t anything warm or lively to attract them merely long, low, narrow sheds by the thousands, with no lights inside. Somewhere a dog barked. With the help of fear and echoes and winter silences, that dog had a voice like a big bronze gong. Billy and the rest were wooed through gate after gate, and Billy saw his first Russian. The man was all alone in the nighta ragbag with a round, flat face that glowed like a radium dial. Billy passed w ithin a yard of him. There was barbed wire between them. The Russian did not wave or speak, but he looked direc tly into Billy39。s fur collar. Billy glanced dully at the coats of his neighbors. T heir coats all had brass buttons or tinsel or piping or numbers or stripes or eagles or moons or stars dangling from them. They were soldiers39。t hay after all. They were overcoats taken from prisoners who were dead. So it goes. It was the guards39。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. 第 27 頁 共 25 頁 There was a lootive, a tender, and three little boxcars. The last boxcar was the railroad guards39。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 essentially 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.

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。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.

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, fa tting, 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.
