No, I am tired and lazy now。 words, realizing that they were a signal, he turned and began to run, splashing through the shallow water. Ignacio ran after him, much helped by his longer legs, his hair flying behind his dark young face, his square teetheach white as a bone and as big as Nicholas39。t run, N icholas, Dr. Island said with the voice of a wave. It only makes him angry that you run. N icholas did not answer, but cut to his left, up the beach and among the trunks of the palms, sprinting all the way because he had no way of knowing Ignacio was not right behind him, about to grab him by the neck. When he stopped it was in the thick jungle, among the boles of the hardwoods, where he leaned,.。 . sound in an atmosphere silent and unwa ked as Earth39。 there was none. He drew a deep breath then and said, Well, that39。 there was only the green hush. The light was still bright and strong and nearly, shadowless, but some interior sense told him the day, was nearly ove r, and he noticed that such faint shades as he could see stretched long, hor izontal distortions of their objects. He felt no hunger, but he had fasted be39。 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。 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。s head。 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。t mistaken after all, was I? I didn39。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 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。s emptie than it used to be. Where Ignacio was, there would have been Red Indian hunters two or three hundred years ago。t anyone,` just the m achines. Now he doesn39。t want anyone around him. Nicholas said slowly, Dr. Island said lots of people wouldn39。t other people around all the time . Remember that? a Only there. are other people around all the time。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。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。m hollow and rotten and turning brown, dirt and old feathers, oozing away. Her beak will break through soon. Okay. Nicholas turned to go. I39。ve swallowed so much I couldn39。t even wet, and do you know something, N icholas? I39。m not really me, I39。t know. Two, three days ago. Ignacio gave me something. 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。s。 pulsive sweeping and scrubbing palliate its anxieties. It is a strength of Freud3
