river whose course they were following through these barren plains, would lead them to some more important river, or to some large lake or inland sea. This was a country entirely unknown, even to the adventurous traders and trappers of the fur companies, who avoided it because it was out of the buffalo range; and because the borders of it, along which they sometimes skirted, were found to be wanting in water-courses in which beaver might be looked for. Walker's company therefore, now determined to prosecute their explorations until they came to some new and profitable beaver grounds.
But after a long march through an inhospitable country they came at last to where the Humboldt sinks itself in a great swampy lake, in the midst of deserts of sage-brush. Here was the end of their great expectations. To the west of them, however, and not far off, rose the lofty summits of the Sierra Nevada range, some of whose peaks were covered with eternal snows. Since they had already made an unprofitable business of their expedition, and failed in its principal aim, that of exploring Salt Lake, they resolved upon crossing the mountains into California, and seeking new fields of adventure on the western side of the Nevada mountains.
Accordingly, although it was already late in the autumn, the party pushed on toward the west, until they came to Pyramid Lake, another of those swampy lakes which are frequently met with near the eastern base of these Sierras. Into this flowed a stream similar to the Humboldt, which came from the south, and, they believed, had its rise in the mountains. As it was important to find a good pass, they took their course along this stream, which they named Trucker's River, and continued along it to its head-waters in the Sierras.
And now began the arduous labor of crossing an un-
