"So Little Chief made his home in the rock-slide high up on the mountain and was happy, for it was just as he thought it would be--no one thought of looking in that bare place for him. For food he ate the pea vines and grasses and other green things that grew just at the edge of the rock-slide and was perfectly happy. One day he decided he would take some of his dinner into his little cave and eat it there. So he cut a little bundle of pea vine and other green things. He left his little bundle on a flat rock in the sun while he went to look for something else and then forgot all about it. It didn't enter his head again until a few days later he happened along by that flat rock and discovered that little bundle. The pea vines and grasses were quite dry, just like the hay Farmer Brown's boy helps his father store away in the barn every summer. "'I guess I don't want to eat that,' said Little Chief, 'but it will make me a very nice bed.' So he carried it home and made a bed of it. There wasn't quite enough, so the next day he cut some more and carried it home at once. But this, being green, soon soured and smelled so badly that he was forced to take it out and throw it away. That set him to thinking. Why was the first he had brought in so dry and sweet and pleasant? Why didn't it spoil as the other had done? He cut some more and spread it out on the big flat rock and once again he forgot. When he remembered and went to look at it two or three days later, he found it just like the first, dry and sweet and very pleasant to smell. This he took home to add to his bed. Then he took home some more that was green, and this spoiled just as the other had done. "Little Chief was puzzling over this as he squatted on a rock taking a sun-bath. The sun was very warm and comforting. After a while the rock on which he sat grew almost hot. Little Chief had brought along a couple of pieces of pea vine on which to lunch, but not being hungry he left them beside him on the rock. By and by he happened to glance at them. They had wilted and already they were beginning to dry. An idea popped into his funny little head. "'It's the sun that does it!' he cried.
