He appeared very much pleased at seeing us again, and invited us to remain at his village three or four days, during which he would supply us with such food as they had, and furnish us with horses for our journey. After the cold, inhospitable treatment we had lately received, this kind offer was peculiarly acceptable. After having made a hasty meal, we accompanied him to his village. Immediately on our arrival, Yellept, who proved to be a man of much influence, collected the inhabitants, and after having made an harangue to them, the object of which was to induce them to treat us hospitably, set them an example by bringing himself an armful of wood, and a platter containing three roasted mullets. They immediately followed the example by furnishing us with an abundance of the only sort of fuel they use,--the stems of shrubs growing in the plains. We then purchased four dogs, on which we supped heartily, having been on short allowance for two days previously. We learned from these people, that, opposite to their village, there was a route which led to the mouth of the Kooskooskee; that the road was good, and passed over a level country well supplied with water and grass; and that we should meet with plenty of deer and antelope. We knew that a road in that direction would shorten our route eighty miles; and we concluded to adopt this route. Fortunately there was among these Walla-wallas a prisoner belonging to a tribe of the Shoshonee Indians. Our Shoshonee woman, Sacajawea, though she belonged to another tribe, spoke the same language as this prisoner; and by their means we were enabled to explain ourselves to the Indians, and to answer all their inquiries with respect to ourselves and the object of our journey. Our conversation inspired them with such confidence, that they soon brought several sick persons for whom they requested our assistance. We splintered the broken arm of one, gave some relief to another whose knee was contracted by rheumatism, and administered what we thought would be useful for ulcers and eruptions of the skin on various parts of the body, which are very common disorders among them. But our most valuable medicine was eye-water, which we distributed, and which, indeed, they very much required; for complaints of the eyes, occasioned by living so much on the water, and aggravated by the fine sand of the plains, were universal among them. We were by no means dissatisfied at this new resource for obtaining subsistence, as the Indians would give us no provisions without merchandise, and our stock was very much reduced. We carefully abstained from giving them any thing but harmless medicines; and our prescriptions might be useful, and were therefore entitled to some remuneration.
