pasturage on the prairies, along
the fresh banks of the rivers, and up every valley and green defile of
the mountains, so the salmon, at their allotted seasons, regulated by a
sublime and all-seeing Providence, swarm in myriads up the great
rivers, and find their way up their main branches, and into the minutest
tributory streams; so as to pervade the great arid plains, and to
penetrate even among barren mountains. Thus wandering tribes are fed in
the desert places of the wilderness, where there is no herbage for the
animals of the chase, and where, but for these periodical supplies, it
would be impossible for man to subsist.
The rapid currents of the rivers which run into the Pacific render the
ascent of them very exhausting to the salmon. When the fish first run
up the rivers, they are fat and in fine order. The struggle against
impetuous streams and frequent rapids gradually renders them thin and
weak, and great numbers are seen floating down the rivers on their
backs. As the season advances and the water becomes chilled, they are
flung in myriads on the shores, where the wolves and bears assemble to
banquet on them. Often they rot in such quantities along the river banks
as to taint the atmosphere. They are commonly from two to three feet
long.
Captain Bonneville now made his arrangements for the autumn and the
winter. The nature of the country through which he was about to travel
rendered it impossible to proceed with wagons. He had more goods
and supplies of various kinds, also, than were required for present
purposes, or than could be conveniently transported on horseback; aided,
therefore, by a few confidential men, he made caches, or secret pits,
during the night, when all the rest of the camp were asleep, and in
these deposited the superfluous effects, together with the wagons. All
traces of the caches were then carefully obliterated. This is a common
expedient with the traders and trappers of the mountains. Having no
established posts and magazines, they make these caches or deposits at
certain points, whither they repair, occasionally, for supplies. It is
an expedient derived from the wandering tribes of Indians.
Many of the horses were still so weak and lame, as to be unfit for
a long scramble through the mountains. These were collected into one
cavalcade, and given in charge to an experienced trapper, of the name
of Matthieu. He was to proceed westward, with a brigade of trappers, to
Bear River; a s
