He thought a long time. "I must find something," he said to himself on which to keep a record. "I must also know when Sunday is. I must rest one day in the week. Yes, I must find something," he said, "on which to write." And finally he found it. He chose two trees standing near each other and then sought for a small sharp stone, which he could make still sharper by striking it on another. When he had got this pen ready he cut into the bark of one tree:
Shipwreck, Sunday, 10th of September, 1875.
He made seven cuts in a row for the seven days in the week. The first cut was longer than the others. This was to represent the Sunday. At sundown every day he made a new cut in the bark.
The other tree he called the month tree. On its stem he was to cut a mark every time his week tree told him a month had passed. But he must be careful, for the months were not of equal length. But he remembered that his teacher had once said in school that the months could be counted on the knuckles and hollows of the hand, in such a way that the long and short months could be found easily and he could tell in this way the number of days in each.
Robinson worked at enlarging his shelter a little every day. He was sorely at loss to find something in which to carry the dirt away from the entrance, or enough so that it would not choke up the opening. A large clam shell was all he could think of at present. He would carry the dirt to the entrance and some distance away, and then throw it. Fortunately the ground sloped away rapidly, so that he needed a kind of platform before his door.
He was careful to open the cleft at some distance above the large opening. For the air was damp and impure in the shelter. But with the opening made high above, fresh air was constantly passing into, and impure air out of, his cave. Light, too, was admitted in this way.

ROBINSON MAKES A HUNTING BAG
Several days passed with Robinson's hat-making and his calendar-making and his watching the sea. Every day his corn and bananas became more distasteful to him. And he planned a longer journey about the island to see if something new to eat could be found.
But he considered that if he went a distance from his cave and found something it would really be of little use to him. "I could eat my fill," he said, "but that is all. And by the time I get back to my cave I will again be hungry. I must find something in which I can gather and carry food." He found nothing.
"The people in New York," he said, "have baskets, or pockets, or bags made of coarse cloth. Of them all, I could most easily make the net, perhaps, of vines. But the little things would fall out of the net. I will see whether I can make a net of small meshes."
But he soon saw that the vines did not give a smooth surface. He thought for a long while. In his garden at home his father had sometimes bound up the young trees with the soft inner bark of others. He wondered if he could use this. He stripped away the outer bark from the tree, which before had yielded him a fibre for his hat, and pulled off the long, smooth pieces of the inner bark. He twisted them together. Then he thought how he could weave the strands together. He looked at his shirt. A piece was torn off and unravelled. He could see the threads go up and down. He saw that some threads go from left to right (woof), others lengthwise (the warp).
From his study of the woven cloth, Robinson saw he must have a firmer thread than the strips of bark gave alone. He separated his bark into long, thin strips. These he twisted into strands or yarn by rolling between his hands, or on a smooth surface. As he twisted it he wound it on a stick. It was slow, hard work. Of all his work, the making of yarn or thread gave him the most trouble. He learned to twist it by knotting the thread around the spindle or bobbin on which he wound it and twirling this in the air. He remembered sadly the old spinning wheel we had seen at his grandmother's house.
His next care was something to hold the threads while he wove them in and out. He had never seen a loom.
After long study Robinson set two posts in the ground and these he bound with seventy-two strands horizontally under each other. Then he tied in the top at the left another thread and wove it in and out through the seventy-two threads. So he tied seventy-two vertical strands and wove them in and out. Thus he had a net three times as long as his foot and as wide as long. He tied the four corners together. He made a woven handle for it and put it on his shoulder like a sack, saying gleefully, "This shall be my hunting bag."

ROBINSON EXPLORES THE ISLAND
After Robinson made his hunting bag he was anxious to set off on his journey of exploring the island. So he arose very early next morning. "Before it is hot," thought he, "I will be quite a distance on my journey." He ate a couple of bananas, scooped up a few handfuls of water from the spring, stuck a few ears of corn in his hunting bag, took his stick in his hand and went forth. As he left his cave the thought struck him: "What if I could not find my cave again? How can I manage so that I can come back to it? I will go away in one direction and return the same way; but suppose I were to lose the way?"
Then he noticed his shadow pointing like a great finger from the sea toward the land. He could direct himself by that. He kept his shadow in front of him. He had noticed, too, that the wind always blew north of the point where the sun rose. This helped him. But sometimes the wind died down.
He had to climb over many rocks and pierce many thickets. At each step he saw a rich growth of plants, stems, leaves, flowers, but nothing to eat, no fruits, or nuts. At length he came to a tree as high as a small church steeple.
Then he thought of what his father had once said about the trees in strange countries. "Many are as tall as a church steeple and the nuts are as big as one's head." He looked again. Yes, there they hung among the leaves, concealed high above in the crown! But so high, it was well that Robinson had learned to climb while on board the ship. He quickly laid down his hunting bag and clambered up the smooth stem of the high tree, a palm. He picked off a nut and threw it down and then several more, and climbed down again.
But the nuts were very hard. How should he open them? He had brought along his sharp stone with which he had stripped off the inner bark. With this he forced off the thick outer shell. But now came the hard nut within, and how hard it was! Striking it was of no use.
Then he threw a great stone on the nut. The shell was crushed and a snow-white kernel lay before him. It tasted like almond. With astonishment Robinson saw in the middle of the nut a large empty space which must have been filled with fluid as the inside was wet. He wished that he had the juice to drink, for he was very thirsty. With this in view, he examined another and riper nut, and the outside came off more easily. But how could he break it and at the same time save the juice? He studied the hull of the cocoanut on all sides. At the ends were three little hollows. He attempted first to bore in with his fingers, but he could not. "Hold!" he cried. "Maybe I can cut them there with the point of my stone knife." This was done without trouble and out of the hole flowed the sweet, white juice.
Robinson put a couple of nuts in his hunting bag, and also the shells from the broken nuts. "Now," he thought, "I shall no longer have to drink from my hand." With this thought he went on his way.
As Robinson came to a rock in his path, out jumped what Robinson took to be a rabbit. He ran after him to catch him, but the rabbit was much the swifter. So Robinson hastened home, but before he reached it the stars were shining with their lustrous light. Tired Robinson stretched his limbs on his bed of grass and leaves and slept soundly.

ROBINSON AS A HUNTER
All the time Robinson was confined to the cave he kept thinking about the rabbit he had seen and how he might catch one. Finally, he determined to make a spear. He broke down a thin, young sapling, stripped
