【正文】 eared to be not a coat but a sort of large black, threecornered hat. There were gummy stains on it, too, like crankcase drainings or old strawberry jam. There seemed to be a dead, furry animal frozen to it. The animal was in fact the coat39。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 stripe s or eagles or moons or stars dangling from them. They were soldiers39。 coats. Billy was the only one who had a coat from a dead civilian. So it goes. And Billy and the rest were encouraged to shuffle around their dinky train and into the prison camp. There wasn39。t anything warm or lively to attract themmerely 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 directly into Billy39。s soul with sweet hopefulness, as though Billy might have good news for himnews he might be too stupid to understand, but good news all the same. Billy blac ked out as he walked through gate after gate. He came to what he thought might be a building on Tralfamadore. It was shrilly lit and lined with white tiles. It was on Earth, though. It was a delousing station through which all new prisoners had to pass. Billy did as he was told, took off his clothes. That was the first thing they told him to do on Tralfamadore, too. A German measured Billy39。s upper right arm with his thumb and forefinger, asked a panion what sort of an army would send a weakling like that to the front. They looked at the other American bodies now, pointed out a lot more that were nearly as bad as Billy39。s. One of the best bodies belonged to the oldest American by far, a high school teacher from Indianapolis. H is name was Edgar De rby. He hadn39。t been in Billy39。s boxcar. He39。d been in Roland Weary39。s car, had cradled Weary39。s head while he died. So it goes. Derby was forty four years old. He was so old he had a son who was a marine in the Pacific theater of war. Derby had pulled political w ires to get into the army at his age. The subject he had taught in Indianapolis was Contemporary Problems in Western Civilization. He also coached the tennis team, and took very good care of his body. Derby39。s son would survive the war. Derby wouldn39。t. That good body of his would be filled with holes by a firing squad in Dresden in sixty eight days. So it goes. The worst American body wasn39。t Billy39。s. The worst body belonged to a car thief from Cicero, Illinois. Ms name was Paul Lazzar o. He was tiny, and not only were his bones and teeth rotten, but his skin was disgusting. Lazzaro was polkadotted all over with dimesized scars. He had had many plagues of boils. Lazzaro, too, had been on Roland Weary39。s boxcar, and had given his word of honor to Weary that he would find some way to make Billy Pilgrim pay for Weary39。s death. He was looking around now, wondering which naked human being was Billy. The na ked Americans took their places under many showerheads along a whitetiled wall. There were no faucets they could control. They could only wait for whatever was ing. Their penises were shriveled and their balls were retracted. Reproduction was not the main business of the evening. An unseen hand turned a master valve. Out of the showerheads gushed scalding rain. The rain was a blowtorch that did not warm. It jazzed and jangled Billy39。s skin without thawing the ice in the marrow of his long bones. The Americans39。 clothes were meanwhile passing through poison gas. Body lice and bacteria and fleas were dying by the billions. So it goes. And Billy zoomed back in time to his infancy. He was a baby who had just been bathed by his mother. Now his mother wrapped him in a towel, carried him into a rosy room that was filled with sunshine. She unwrapped him, laid him on the tickling towel, powdered him between his legs, joked with him, patted his little jelly belly. Her palm on his little jelly belly made potching sounds. Billy gurgled and cooed. And then Billy was a middleaged optometrist again, playing hacker39。s golf this time on a blazing summer Sunday morning. Billy never went to church any more. He was hacking with three other optometrists. Billy was on the green in seven strokes, and it was his turn to putt. It was an eightfoot putt and he made it. He bent over to ta ke the ball out of the cup, and the sun went behind a cloud. Billy was momentarily dizzy. When he recovered, he wasn39。t on the golf course any more. He was strapped to a yellow contour chair in a white chamber aboard a flying saucer, which was bound for Tralfamadore. 39。Where am I?39。 said Billy Pilgrim. 39。Trapped in another blob of amber, Mr. Pilgrim. We are where we have to be just nowthree hundred million miles from Earth, bound for a time warp which will get us to Tralfamadore in hours rather than centuries.39。 39。Howhow did I get here?39。 39。It would ta ke another Earthling to explain it to you. Earthlings are the great explainers, explaining why this event is structured as it is, telling how other events may be achieved or avoided. I am a Tralfamadorian, seeing all time as you might see a stretch of Rocky Mountains. All time is all time. It does not change. It does not lend itself to warnings or explanations. It simply is. Take it moment by moment, and you will find that we are all, as I39。ve said before, bugs in amber.39。 39。You sound to me as though you don39。t believe in free will,39
