These proved excellent food and were so abundant as to furnish Robinson with all the fish he wanted as long as he stayed on the island. XXXIII ROBINSON BUILDS A BOAT Robinson had wished for a boat many times. He wished to explore the shore of his island. He wanted to go clear around it so that he might see it on every side. But he knew the work of making a boat would be great, if not wholly impossible. The shaping of boards to build a boat with his rude tools was not to be thought of. He knew how the Indians made boats out of bark of trees. But he saw that for his purpose so light a boat would not do. He finally remembered a second Indian way of making a boat by hollowing out a large log. The forest was full of the boles of trees that had been blown down. But they were far away from the shore. At first he did not think of this very much. He had overcome so many difficulties that he thought, "Never mind, I will get my boat to water, no matter where I make it, in some way." So he selected a tree trunk some distance from the bank of the little creek near his cave and began work. He had first to burn out his log the proper length and hack it into boat shape with his stone tools. This was very slow and tedious work. He had to handle the fire with great care for there was always the danger of spoiling the shape of the slowly forming boat. Both ends must be sharpened, but one more than the other to form the prow or forward going end. After he had shaped his boat, he began hollowing it out. This he did also by burning for the most part. He used the branches of pitch bearing trees for this purpose. But it was so slow. He worked at his boat all the time he could spare from his regular duties in attending to his goats, his garden and his cave. He was always making his cave larger. Every time he made a piece of furniture or stored away grain he must make more room in his cave by digging away the earth and carrying it out. He had made a large strong wicker basket for this purpose. He had had a vague idea that when he got his boat done he would dig a trench back from the bank of the creek and thus float his boat. But he had not thought it out clearly. "Or anyway," he thought, "I can in some way manage to roll it to the water." He must now actually plan to put some of these ideas into effect. He first went over the ground and found that to dig a trench from the water to the boat, so that the water would come to the boat, he would have to dig it twenty feet deep. "I can never do this," he said, "with my poor tools."
