"Many reasons had determined us to remain at Fort Clatsop until the first of April," says the journal entry of March 22d. "Besides the want of fuel in the Columbian plains, and the impracticability of passing the mountains before the beginning of June, we were anxious to see some of the foreign traders, from whom, by means of our ample letters of credit, we might have recruited our exhausted stores of merchandise. About the middle of March, however, we had become seriously alarmed for the want of food; the elk, our chief dependence, had at length deserted their usual haunts in our neighborhood and retreated to the mountains. We were too poor to purchase other food from the Indians, so that we were sometimes reduced, notwithstanding all the exertions of our hunters, to a single day's provisions in advance. The men, too, whom the constant rains and confinement had rendered unhealthy, might, we hoped, be benefited by leaving the coast and resuming the exercise of travel. We therefore determined to leave Fort Clatsop, ascend the river slowly, consume the month of March in the woody country, where we hoped to find subsistence, and in this way reach the plains about the first of April, before which time it will be impossible to attempt to cross them."

The next day the canoes were loaded, and in the afternoon the party took leave of Fort Clatsop.

Though the return along the Columbia was less fraught with danger than the descent, it was much more toilsome. Going down, the men had taken large chances in shooting the rapids; but coming back, portage had to be made of all such places. For this work horses were absolutely necessary; and to get a few of these from the Indians, who saw their chance for gain, brought the expedition to a state verging upon downright bankruptcy. Enough horses were secured, however, to enable them to pass step by step over the obstructions in their way, until at last the Great Falls were left behind. From that point they meant to proceed by land; and as the canoes were of no further use, they were cut up for firewood, which could not be otherwise obtained on the treeless plains.

Thus far there had been no adventures of note, except such as grew out of the ill-nature and rascality of the Indians, who swarmed upon the banks of the stream, where they were assembled for their annual salmon-fishing. More than once the officers found it necessary to use harsh measures, in dealing with cases of theft. In striking contrast to these experiences was the meeting with the Walla-Wallas, a short distance above the Falls. These people freely gave to the travelers from their own scant supply of firewood and food; and the chief presented to Captain Clark a superb white horse, a kindness which Clark requited by the gift of his artillerist's sword. After leaving this hospitable village, the party was overtaken by three young men, Walla-Wallas, who had come a day's journey in order to restore a steel trap, inadvertently left behind.

May 5th they came again to the lower villages of the Nez Percés, where they had stopped in the preceding October to make their dugout canoes. By this time they were practically destitute of all resources save those of the mind. To secure food, they were obliged to resort to the practice of medicine! Luckily, the scheme worked. Their patients were almost legion; their fame spread like a prairie fire. Nor was this mere quackery. All of the Indians of the Western slope were more or less afflicted with rheumatism, inflammation of the eyes, and other ills incident to an outdoor life in a humid climate; and the two officers, in the course of preparing themselves for their errand across the continent, had learned to use some of the simple remedies of the day. In some cases they gave relief to the sufferers; in others, wrote Captain Lewis, "we conscientiously abstained from giving them any but harmless medicines; and as we cannot possibly do harm, our prescriptions, though unsanctioned by the faculty, may be useful, and are entitled to some remuneration." They were thus enabled to secure the day's food, and to provide a little against the morrow. But severe trials yet remained.

"May 6th [after taking up the trail].... It was now so difficult to procure anything to eat that our chief dependence was on the horse which we received yesterday for medicine; but to our great disappointment he broke the rope by which he was confined, made his escape, and left us supperless in the rain."

Upon falling in again (on May 8th) with the band of Nez Percés in whose care they had left their horses in the autumn, they found the animals to be now much scattered over the plain, where they had been turned out to graze; but the chief promised to have them collected at once. He said further that his people had been made aware of the approach of the travelers, and of their being without provisions, and that he had a few days before dispatched several of his men to meet them, bearing supplies; but this relief party had taken another trail, and so missed a meeting.

This old chief and his people showed themselves to be genuine friends. After two or three days, when their guests had explained their situation, and offered to exchange a horse in poor flesh for one that was fatter and more fit to be eaten, the chief was deeply offended by this conception of his hospitality, remarking that his tribe had an abundance of young horses, of which the men might use as many as they chose; and some of the warriors soon brought up two young and fat animals, for which they would accept nothing in return.

To hold speech with this tribe was awkward. "In the first place," wrote Captain Lewis, "we spoke in English to one of our men, who translated it into French to Chaboneau; he interpreted it to his wife in the Minnetaree language; she then put it into Shoshone, and a young Shoshone prisoner explained it to the Chopunnish in their own dialect." But the common impulses of humanity found expression in more direct ways, without need for interpretation. Whether as friends or foes, the Nez Percés have always been celebrated for their generosity; and in those hard days they seemed to be just in their element. They could not do enough to show their good will.

The expedition went into camp at a little distance from this village, waiting for their horses to be assembled, and waiting for the melting of the mountain snows, which now rendered further progress impossible. In this camp they remained until June 10, unwilling to impose upon their hosts, and hence were in sore straits most of the time.
