【正文】 n which side of hunger he stood。 he was not as strong as he had been only a day past, and by this time next day he would probably be unable to outrun Ignacio. He should, he now realized, have eaten the monkey he had ki lled。 but his stomach revolted at the thought of the raw flesh, and he did not know how he might build a fire, although Ignacio seemed to have done so the night before. Raw fish, even if he were able to c atch a fish, would be as bad, or worse, than raw monkey。 he remembered his effort to open a coconuthe had failed, but it was surely not impossible. His mind was hazy as to what a coconut might contain, but there had to be an edible core, because they were eaten in books. He decided to make a wide sweep through the jungle that would bring him back to the beach well away from Ignacio。 he had several times seen coconuts lying in the sand under the trees. He moved quietly, still a little afraid, trying to think of ways to open the coconut w hen he found it. He imagined himself standing before a large and raggedly faceted stone, holding the coconut in both hands. He raised it and smashed it dow n, but when it struc k it was no longer a coconut but Maya39。s head。 he heard her nose cartilage break with a distinct, rubbery snap. Her eyes, as blue as the sky above Madhya Pradesh, the sparkling blue sky of the egg, looked up at him, but he could no longer look into them, they retreated from his own, and it came to him quite suddenly that Lucifer, in falling, must have fallen up, into the fires and the coldness of space, never again to see the warm blues and browns and greens of Earth: 1 was watching Sata n fall as lightning from heaven. He had heard that on tape somewhere, but he could not remember where. He had read that on Earth lightning did not e down from the clouds, but leaped up from the plaary surface toward them, never to return. Nicholas. He listened, but did not hear his name again. Faintly water was babbling。 had Dr. Island used that sound to speak to him? He walked toward it and found a little rill that threaded a way among the trees, and followed it. In a hundred steps it grew broader, slowed, and ended in a long blind pool under a dome of leaves. . Diane was sitting on moss on the side opposite him。 she looked up as she saw him, and smiled. Hello, he said. Hello, Nicholas. I thought I heard you. I wasn39。t mistaken after all, was I? I didn39。t think I said anything. He tested the dark water with his foot and found that it was very cold. You gave a little gasp, I fancy. I heard it, and I said to myself, that39。s Nicholas, and I called you. Then I thought I might be wrong, or that it might be Ignacio. Ignacio was chasing me. Maybe he still is, but h think he39。s probably given up by now. The girl nodded, looking into the dar k waters of they pool, but did not seem to have heard him. He began to wor k his way around to her, climbing across the sna kelike roots of the crowding trees. Why does Ignacio want to kill me, Diane? Sometimes he wants to kill me, too, the girl said. But why? I think he39。s a bit frightened of us. Have you ever talked to him, Nicholas? Today I did a little. He told me a story about a pet fish he used to have. Ignacio grew up all alone。 did he tell you that? On= Earth. On a plantation in Brazil, way up the Amazon Dr. Island told me. I thought it was crowded on Earth. The cities are crowded, and the countryside closes to the cities. But there are places where it39。s emptie than it used to be. Where Ignacio was, there would have been Red Indian hunters two or three hundred years ago。 when he was there, there wasn39。t anyone,` just the machines. Now he doesn39。t want to be looked at, doesn39。t want anyo ne around him. Nicholas said slowly, Dr. Island said lots of people wouldn39。t be sick if only there weren39。t other people around all the time. Remember that? a Only there. are other people around all the time。 that39。s how the world is. Not in Brazil, maybe, Nicholas said. He was trying to remember something about Brazil, but the only thing he could think of was a parrot singing in a straw hat from the view cartoons。 and then a turtle and a hedgehog that turned into armadillos for the love of God, Montressor. He said, Why didn39。t he stay there? Did I tell you about the bird, Nicholas? She had been not listening again. What bird? I have a bird. Inside. She patted the flat stomach below her small breasts, and for a moment, Nicholas thought she had really found food. She sits in here. She has tangled a nest in my entrails, where she sits and tears at my breath with her beak. I look healthy to you, don39。t I? But inside I39。m hollow and rotten and tur ning brown, dirt and old feathers, oozing away. Her beak will break through soon. Okay. Nicholas turned to go. I39。ve been drinking water here, trying to drown her. I think I39。ve swallowed so much I couldn39。t stand up now if I tried, but she isn39。t ev en wet, and do you know something, N icholas? I39。ve found out I39。m not really me, I39。m her. Turning back Nicholas asked, When was the last time you had anything to eat? I don39。t know. Two, three days ago. Ignacio gave me something. I39。m going to try to open a coconut. If I can I39。ll bring you back some. When he reached the beach, Nicholas turned and walked slowly bac k in the direction of the dead fire, this time along the rim of dampened sand between the sea and the palms. He was thinking about machines. There were hundreds of thousands, perhaps millions, of machines out beyond the belt, but few or none of the sophisticated servant robots of Earththose were luxuries. Would Ignacio, in Brazil (whatever that was like), have had such luxuries? N icholas thought not。 those r obots were almost like people, and living with them would be like living with peopl
