Captain Clark went ahead to reconnoitre, and found that the Indians had rather understated the difficulties of the water route. To descend the Lemhi was entirely out of the question. Clark dispatched a messenger to Captain Lewis, telling of what he had discovered, and wrote in his journal (August 24th):—

"The plan I stated to Captain Lewis if he agrees with me we shall adopt is to precure as many horses (one for each man) if possable and to hire my present guide who I sent on to him to interegate thro' the Intptr. and proceed on by land to some navagable part of the Columbia river, or to the Ocean, depending on what provisions we can Precure by the gun aded to the small stock we have on hand depending on our horses as the last resort."

While he was writing so calmly of his plan, he and his men were suffering from hunger, having only a meagre supply of fish and dried berries. A day or two later he wrote:—

"These Indians, to whom this life is familiar, seem contented, although they depend for subsistence on the scanty provisions of the fishery. But our men, who are used to hardships, but have been accustomed to have the first wants of Nature regularly supplied, feel very sensibly their wretched situation; their strength is wasting away; they begin to express their apprehensions of being without food in a country perfectly destitute of any means of supporting life, except a few fish."

Horses were purchased from the Shoshones, and the men were employed in making pack-saddles. As there was no timber to be obtained near by, the oars were cut up for boards, and these were fastened into form with thongs of rawhide. With the best provision that could be made, however, it was apparent that a considerable portion of the baggage must be cached and left behind. At a time when the needs of the men would be greatest, they were obliged to provide themselves with least.

The Shoshones were hospitable and kindly folk. Throughout these days of preparation, the women were engaged in making and repairing moccasins and clothing for the men, and the fishermen gave to them a good share of the daily catch. Nor was the kindness all upon the one side. The white hunters, with their guns, had greater success than the Indians, who were armed only with bows and arrows and lances. Share and share alike was the rule in the village. Once when the hunters brought in a deer, Captain Clark directed that it be given to the women and children, who were in an extremity of hunger, and himself went supperless to bed.

One of the older men was induced to accompany them as a guide. By the middle of September they were deep in the mountains, and also deep in peril and suffering. The cold had a depressing effect upon the men, overworked and underfed as they were. For several days they got along somehow, with a few odds and ends of small game; but on the 14th of September, Captain Clark's prevision was fulfilled, and they were reduced to supping upon the flesh of one of their ponies. Then on the next day,—

"September 15th. Camped near an old snow-bank, some of which was melted, in the absence of water; and here the party supped on the remains of the colt killed yesterday. Our only game to-day was two pheasants; the horses, on which we calculated as a last resource, began to fail us, for two of them were so poor and worn out with fatigue that we were obliged to leave them behind.

"September 16th. Three hours before daybreak it began to snow, and continued all day, so that by evening it was six or eight inches deep. This covered the track so completely that we were obliged constantly to halt and examine, lest we should lose the route. In many places we had nothing to guide us, except the branches of the trees, which, being low, had been rubbed by the burdens of the Indian horses.... Wet to the skin, and so cold that we were anxious lest our feet should be frozen, as we had only thin moccasins to defend them.... We camped on a piece of low ground, thickly timbered, but scarcely large enough to permit us to lie level. We had now made thirteen miles. We were all very wet, cold, and hungry.... Were obliged to kill a second colt for our supper."

Of the stock of portable provisions there remained only a few cans of soup and about twenty pounds of bear's oil; and there was "no living creature in these mountains, except a few pheasants, a small species of gray squirrel, and a blue bird of the vulture kind about the size of a turtle-dove or jay; even these are difficult to shoot."
