He sat down on the thick, soft grass by the side of the packs, and his physical system, keyed up so long, suffered a collapse, complete but not unpleasant. Every nerve relaxed and he sank back against his pack, content to be idle as long as Boyd was away. But while his body was weak then, his mind was content. Clarke Valley, which had been named after him, was surely wonderful. It was green and fresh everywhere and Boyd Lake was molten silver. Not far away the cataract showed white against the mountainside, and its roar came in a pleasant murmur to his ears. He heard a distant shot, but it did not disturb him. He knew it was Boyd, shooting something, probably the elk he wished. After a while he heard another report, and he put that down as the bear. His surmise was correct in both instances. Boyd, with his help, skinned both the bear and the elk, and they hung great quantities of the flesh of both in the trees to dry. Boyd carefully scraped the skins with his hunting knife, and they, too, were hung out to dry. While they were hanging there Will also shot a bear, and his hairy covering was added to the others. A few days later Boyd built the wickiup, called by the Sioux tipiowinja. Taking one of the sharp axes he quickly cut a number of slender, green poles, the larger ends of which he sharpened well and thrust deep into the ground, until he had made with them a complete circle. The smaller ends were bent toward a common center and fastened tightly with withes of skin. The space between was thatched with brush, and the whole was covered with the skins of elk and bear, which Boyd stitched together closely and firmly. Then they cut out a small doorway, which they could enter by stooping. The floor was of poles, made smooth and soft with a covering of dead leaves. It was rude and primitive, but Will saw at once that in need it would protect both their stores and themselves. "I learned that from the Sioux long ago," said Boyd, not without some admiration of his handiwork. "It's close and hot, and after we've put the stores in we'll have to tuck ourselves away in the last space left. But it will feel mighty good in a storm." The second night after the wickiup was finished his words came true. A great storm gathered in the southwest, the first that Will had seen in the high mountains, and it was a tremendous and terrifying manifestation of nature.
