The conditions of the rapids below The Dalles was such that one boat, fortunately empty, was lost, and the upper rapids being impracticable, they broke up or traded all their boats and canoes but two, which were carried to the upper river. They proceeded with the horses, that had been purchased with the greatest difficulty, Bratton, too ill to walk, being on horseback, and on April 27th reached a village of the Wallawallas, near the mouth of Snake or Lewis River. Here they were so well received that Lewis says: "Of all the Indians whom we have met since leaving the United States, the Wallawallas were the most hospitable, honest, and sincere." Their horses recruited to twenty-three head, cheered by information of a new route which would save eighty miles, and with Wallawalla guides, they moved in early May up the valley of Snake or Lewis River, and finding it too early to cross the mountains, encamped in the forks of the Kooskoosky, having meanwhile received back from their savage friend Twisted-hair their thirty-eight horses intrusted to his care the previous year. Their journey by land was marked by great scarcity of food, which was roots or dog, except when the officers, practicing medicine for sick Indians, obtained horses for food. The use of dog, which was now very palatable, caused derision among the Indians. On one occasion an Indian threw a half-starved puppy into Lewis's plate, with laughter, which turned to chagrin when Lewis flung the animal with great force into the savage's face and threatened to brain him with a tomahawk. The Indians lived almost entirely on fish during the salmon season, and on roots the rest of the year. Their houses were collected under one roof, with many apartments, and two were seen each about one hundred and fifty feet long. The difficulties of communicating with the Chopunish were very great, and if errors occurred it was not astonishing. Lewis spoke in English, which was translated by one of the men in French to Chaboneau, who repeated it in Minnetaree to his wife. She put it into Shoshonee to a prisoner, who translated it into Chopunnish dialect. An attempt in early June to cross the mountains failed, the snow being ten feet deep on a level. On June 24th they started again, and with great privations succeeded in following their trail of the previous September across the Bitterroot Mountains to Traveller's-rest Creek, on Clark Fork, which was reached June 30th. Here the party divided in order to thoroughly explore different portions of the country. Lewis took the most direct route to the great falls of the Missouri, whence he was to explore Maria's River to 50° N. latitude. Clark proceeded to the head of Jefferson River, down which Sergeant Ordway was to go in the canoes cached there. Clark himself was to cross by the shortest route to the Yellowstone, and building canoes, descend to its mouth and rejoin the main party at that point.
