The Adventures of Captain Bonneville, U. S. A., in the Rocky Mountains and the Far West

springs, and brooks, and rock-bound lakes. From this great treasury of waters issue forth limpid streams, which, augmenting as they descend, become main tributaries of the Missouri on the one side, and the Columbia on the other; and give rise to the Seedske-dee Agie, or Green River, the great Colorado of the West, that empties its current into the Gulf of California.
    The Wind River Mountains are notorious in hunters’ and trappers’ stories: their rugged defiles, and the rough tracts about their neighborhood, having been lurking places for the predatory hordes of the mountains, and scenes of rough encounter with Crows and Blackfeet. It was to the west of these mountains, in the valley of the Seedske-dee Agie, or Green River, that Captain Bonneville intended to make a halt for the purpose of giving repose to his people and his horses after their weary journeying; and of collecting information as to his future course. This Green River valley, and its immediate neighborhood, as we have already observed, formed the main point of rendezvous, for the present year, of the rival fur companies, and the motley populace, civilized and savage, connected with them. Several days of rugged travel, however, yet remained for the captain and his men before they should encamp in this desired resting-place.
    On the 21st of July, as they were pursuing their course through one of the meadows of the Sweet Water, they beheld a horse grazing at a little distance. He showed no alarm at their approach, but suffered himself quietly to be taken, evincing a perfect state of tameness. The scouts of the party were instantly on the look-out for the owners of this animal; lest some dangerous band of savages might be lurking in the vicinity. After a narrow search, they discovered the trail of an Indian party, which had evidently passed through that neighborhood but recently. The horse was accordingly taken possession of, as an estray; but a more vigilant watch than usual was kept round the camp at nights, lest his former owners should be upon the prowl.
    The travellers had now attained so high an elevation that on the 23d of July, at daybreak, there was considerable ice in the waterbuckets, and the thermometer stood at twenty-two degrees. The rarefy of the atmosphere continued to affect the wood-work of the wagons, and the wheels were incessantly falling to pieces. A remedy was at length devised. The tire of each wheel was taken off; a band of wood was nailed round the exterior of the felloes, the tire was then made red hot, replaced round the wheel, and suddenly cooled with water. By this means, the whole was bound together with great compactness.
    The extreme elevation of these great steppes, which range along the feet of the Rocky Mountains, takes away from the seeming height of their peaks, which yield to few in the known world in point of altitude above the level of the sea.
    On the 24th, the travellers took final leave of the Sweet Water, and keeping westwardly, over a low and very rocky ridge, one of the most southern spurs of the Wind River Mountains, they encamped, after a march of seven hours and a half, on the banks of a small clear stream, running to the south, in which they caught a number of fine trout.
    The sight of these fish was hailed with pleasure, as a sign that they had reached the waters which flow into the Pacific; for it is only on the western streams of the Rocky Mountains that trout are to be taken. The stream on which they had thus encamped proved, in effect, to be tributary to the Seedske-dee Agie, or Green River, into which it flowed at some distance to the south.
    Captain Bonneville now considered himself as having fairly passed the crest of the Rocky Mountains; and felt some degree of exultation in being the first individual that had crossed, north of the settled provinces of Mexico, from the waters of the Atlantic to those of the Pacific, with wagons. Mr. William Sublette, the enterprising leader of the Rocky Mountain Fur Company, had, two or three years previously, reached the valley of the Wind River, which lies on the northeast of the mountains; but had proceeded with them no further.
    A vast valley now spread itself before the travellers, bounded on one side by the Wind River Mountains, and to the west, by a long range of high hills. This, Captain Bonneville was assured by a veteran hunter in his company, was the great valley of the Seedskedee; and the same informant would have fain persuaded him that a small
