After his honorable discharge from the Army in 1945, Billy again enrolled in the Ilium School of Optometry. During his senior year there, he became engaged to the daughter of the founder and owner of the school, and then suffered a mild nervous collapse. He was treated in a veterans39。F has sixtyeight thousand employees in Ilium. That calls for a lot of lenses and a lot of frames. Frames are where the money istion of coalmines was far distant and there was no dread of scarcity. There were still extensive mines to be worked in the two Americas. The manufactories, appropriated to so many different uses, lootives, steamers, gas works, amp。 but the consumption had so increased during the last few years, that certain beds had been exhausted even to their smallest veins. Now deserted, these mines perforated the ground with their useless shafts and forsaken galleries. This was exactly the case with the pits of Aberfoyle. Ten years before, the last butty had raised the last ton of coal from this colliery. The underground working stock, traction engines, trucks which run on rails along the galleries, subterranean tramways, frames to support the shaft, pipes in short, all that constituted the machinery of a mine had been brought up from its depths. The exhausted mine was like the body of a huge fantasticallyshaped mastodon, from which all the ans of life have been taken, and only the skeleton remains. Nothing was left but long wooden ladders, down the Yarrow shaft the s, carpenters, outside and inside laborers, women, children, and old men, all were collected in the great yard of the Dochart pit, formerly heaped with coal from the mine. Many of these families had existed for generations in the mine of old Aberfoyle。 feet, and silence succeeded to the bustling life which had till then filled the Aberfoyle mines. One man alone remained by James Starr. This was the overman, Simon Ford. Near him stood a boy, about fifteen years of age, who for some years already had been employed down below. James Starr and Simon Ford knew and esteemed each other well. Goodby, Simon, said the engineer. Goodby, Mr. Starr, replied the overman, let me add, till we meet again! Bill became rich. He had two children, Barbara and Robert. In time, his daughter Barbara married another optometrist., and Billy set him up in business. Billy39。t resume practice. He had a housekeeper. His daughter came over almost every day. And then, without any warning, Billy went to New York City, and got on an allnight radio program devoted to talk. He told about having e unstuck in time. He said, too, that he had been kidnapped by a flying saucer in 1967. The saucer was from the pla Tralfamadore, h e said. He was taken to Tralfamadore, where he was displayed naked in a zoo, he said. He was mated there with a former Earthling movie star named Montana Wildhack. Some night owls in Ilium heard Billy on the radio, and one of them called Billy39。s wedding. He hadn39。s friends. Their suction cups were on the ground, and their shafts, which were extremely flexible, usually pointed to the sky. At the top of each shaft was a little hand with a green eye in its palm. The creatures were friendly, and they could see in four dimensions. They pitied Earthlings for being able to see only three. They had many wonderful things to teach Earthlings, especially about time. Billy promised to tell what some of those wonderful things were in his next letter. Billy was working on his second letter when the first letter was published. The second letter started out like this: 39。When a Tralfamadorian sees a corpse, all he thinks is that the dead person is in a bad condition in that particular moment, but that the same person is just fine in plenty of other moments. Now, when I myself hear that somebody is dead, I simply shrug and say what the Tralfamadorians say about dead people, which is so it goes.39。s day off. There was an old typewriter in the rumpus room. It was a beast. It weighed as much as a storage battery. Billy couldn39
