No, I am tired and lazy now。 if I pursue you I will not catch you, and if I catch youthrough your own slowness and clumsinessI will not kill you, and if I kill you I will not eat you. Nicholas had begun to back away, and at the last。 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。s thumbnailshowing like spectators who lined the railings of his lips. Don39。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,.。 out of breath, the thumping of his own heart the only39。 . sound in an atmosphere silent and unwa ked as Earth39。s long, prehuman day. For a time he listened for any sound Ignacio might m ake searching for him。 there was none. He drew a deep breath then and said, Well, that39。s over, expecting Dr. Island to answer from somewhere。 there was only the green hush. The light was still bright and strong and nearly, shadowless, but some interior sense told him the day, wa s nearly over, 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。 fore and knew on 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 killed。 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 catch 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 w
