The air was so clear that Williamstown seemed close. So, after resting a few minutes and drawing the sign on a flat rock to show which way he had gone, he started down the west side of the mountain on a run, whooping and yelling like an Indian at every jump. Then, just as he was thinking how easy it was and what fun he would have bragging to us boys about what he had done, he caught his foot in a root or something, fell headlong, rolled down until he struck a tree; then lay still. How long he had lain there, when he finally came to life again, he couldn't tell. At first he didn't know where he was or what had happened. Then he remembered and tried to get on his feet and go on. With a cry of pain, he sank back again. He had sprained his ankle and hardly could move it without yelling. When Robinson Crusoe was shipwrecked on an island he wrote on a piece of paper the good things and the bad things that had happened to him. To start with, he wrote on one side, "I am shipwrecked on an island," or something like that, and on the other, "but I am alive." Bill did the same, only he didn't write it. He thought it. "I've busted my ankle," he said to himself, "but I didn't break my bottles or spill my water. "I can't walk a step, but I can yell to beat the band. "I can't get to Williamstown and I can't get home, but I have something to eat in my pack and plenty of matches in my pocket. "Nobody knows where I am, but----" That last "but" was to much for Bill. He couldn't find anything to go with it, for he began to think of what Pa had told us, that if a person should get hurt on the mountain he might die there and not be found for weeks or years. His ankle was aching fearfully, too. He tried yelling for a while and Bill is the best yeller that I ever saw or heard. "Help! Help!" he cried. "HELP!" He might as well have saved his breath for all the good it did. Then he lay still for a long time, trying to think what to do. That was what Mr. Norton had told us. "If anything happens," said he, "don't lose your heads. Think it over calmly. Decide what is best to do and then do it." "I'm a Scout," said Bill to himself, "and, bet your life, I ain't a going to stay here and die on no mountain." He took off his shoe and stocking and bathed his ankle in water from one of the bottles--not much water because he couldn't spare it, and he took a little sip himself. Then he thought of his "first aid to the injured" package. "What's the matter with bandaging myself?" said he. "It will be good practice." When he had finished and had rested a few minutes, he found that his ankle did not hurt him quite so much and that he could move around a little, if he didn't bear any weight on it. He thought at first that he would crawl on his hands and knees to Williamstown, or until he came to some house, but when he tried he found that he couldn't do it.
