It was then dark and the moon shone bright in the heavens. Robinson gathered a heap of dry grass and made himself a safe bed. But as he lay there he saw the moonbeams shining into his cave. He sprang up. "How easy," he thought, "for wild animals to creep in here upon me." He crawled out and looked around. Not far from the cave he saw a large flat stone. With great trouble he rolled it to the opening of his cave, but before this the morning began to dawn. He went inside the shelter, seized the stone with both hands and rolled it into the opening till it almost closed it. "I have now a closed home. I can again stretch my legs. Wind and rain cannot get at me, nor wild animals." X ROBINSON MAKES A HAT Refreshed and with renewed strength, Robinson awoke late the next morning, but he had a bad headache. The day before the hot tropic sun had beat down on his bare head, as he worked at his cave. He was so busy that he forgot to go into the shade from time to time in order to shield himself from the scorching sunshine. He felt a new need. "I must make me a hat," said Robinson to himself. "But how?" He had no straw, no thread and no needle. He looked around for a long time, but found nothing. The sun mounted even higher in the heavens, and shone hotter and hotter. He went to seek shelter at last in the deep shade of a nearby tall plant. As he stood there he examined the plant more carefully. "Out of these leaves," he said, "I might make a hat." He climbed up the short stem of the plant and saw that it had not only leaves as long as himself, but between the leaves were big bunches of long, thin fruit, as thick as three fingers and similar in shape to a cucumber. He plucked the leaves and fruit and was about to eat some of the fruit when he heard near him a light stir as of some animal. He rolled the leaves and fruit together and hastened back to the cave. [Illustration: THE BANANA TREE] The bananas, for that is what the fruit proved to be, were sweet and refreshing. After he had eaten enough he set immediately about making his hat. He broke off a couple of reeds. He bent one into a hoop. But the hoop would not hold without thread. Sometimes it was too large and sometimes too small. But it must fit his head. He pulled up grass and bound its ends together, but the grass stalks were not strong enough. He hunted until he found a tree whose inner bark was soft and came out in long fibres. He bound his reed with this. This, too, made the hoop soft so that it did not hurt his head.
