"Besides, the Sioux, or, in their own language, the Dakotas, are a great nation made up of smaller nations, all of the same warlike stock. There is the tribe of the Mendewakaton, which means Spirit Lake Village, then you have the Wahpekute or Leaf Shooters; the Wahpeton, the Leaf Village; the Sisseton, the Swamp Village; the Yankton, the End Village, the Yanktonnais, the Upper End Village, and the Teton, the Prairie Village. The Teton tribe, which is very formidable, is subdivided into the Ogalala, the Brule, and the Hunkpapa. Red Cloud, as I've told you before, is an Ogalala. And that's a long enough lesson for you for one day. Now, like a good boy, go catch some fish." Will had discovered very early that Lake Boyd, which was quite deep, contained fine lake trout and also other fish almost as good to the taste. As their packs included strong fishing tackle it was not difficult to obtain all the fish they wanted, and the task generally fell to the lad. Now, at Boyd's suggestion, he fulfilled it once more with the usual success. Game of all kinds, large and small, was abundant, the valley being fairly overrun with it. Boyd said that it had come in through the narrow passes, and its numbers indicated that no hunters had been there in a long time. Will even found a small herd of about a dozen buffaloes grazing at the south end of the valley, but the next day they disappeared, evidently alarmed by the invasion of human beings. But the deer continued numerous and there were both bears and mountain lions along the slopes. Will, who had a certain turn for solitude, being of a thoughtful, serious nature, ceased to find the waiting in the valley irksome. He began to think less of the treasure for which he had come so far and through such dangers. They _had_ found a happy valley, and he did not care how long they stayed in it, all nature being so propitious. He had never before breathed an air so fine, and always it was redolent with the odor of pine and balsam. He began to feel that Boyd had not exaggerated much when he talked about his increase in height and chest expansion. Both he and the hunter bathed every morning in Lake Boyd. At first Will could not endure its cold water more than five minutes, but at the end of ten days he was able to splash and swim in it as long as he liked. Their days were not all passed in idleness, as they replenished their stores by jerking the meat of both bear and deer. At the end of two weeks the hunter began to talk of departure, and he and Will walked toward the western end of the valley, where the creek issued in a narrow pass, the only road by which they could leave. "It's likely to be a mighty rough path," said Boyd, "but our horses are still mountain climbers and we'll be sure to make it." They went a little nearer and listened to the music of the singing waters, as the creek rushed through the cleft. It was a fine, soothing note, but presently another rose above it, clear and melodious.
