Such a confederate band of Shoshonies and Flatheads was the one met by our travellers.  It was bound on a visit to the Arrapahoes, a tribe inhabiting the banks of the Nebraska.  They were armed to the best of their scanty means, and some of the Shoshonies had bucklers of buffalo hide, adorned with feathers and leathern fringes, and which have a charmed virtue in their eyes, from having been prepared, with mystic ceremonies, by their conjurers.

In company with this wandering band our travellers proceeded all day.  In the evening they encamped near to each other in a defile of the mountains, on the borders of a stream running north, and falling into Bighorn River.  In the vicinity of the camp, they found gooseberries, strawberries, and currants in great abundance.  The defile bore traces of having been a thoroughfare for countless herds of buffaloes, though not one was to be seen.  The hunters succeeded in killing an elk and several black-tailed deer.

They were now in the bosom of the second Bighorn ridge, with another lofty and snow-crowned mountain full in view to the west.  Fifteen miles of western course brought them, on the following day, down into an intervening plain, well stocked with buffalo.  Here the Snakes and Flatheads joined with the white hunters in a successful hunt, that soon filled the camp with provisions.

On the morning of the 9th of September, the travellers parted company with their Indian friends, and continued on their course to the west.  A march of thirty miles brought them, in the evening, to the banks of a rapid and beautifully clear stream about a hundred yards wide.  It is the north fork or branch of the Bighorn River, but bears its peculiar name of the Wind River, from being subject in the winter season to a continued blast which sweeps its banks and prevents the snow from lying on them.  This blast is said to be caused by a narrow gap or funnel in the mountains, through which the river forces its way between perpendicular precipices, resembling cut rocks.

This river gives its name to a whole range of mountains consisting of three parallel chains, eighty miles in length, and about twenty or twenty-five broad.  One of its peaks is probably fifteen thousand feet above the level of the sea, being one of the highest of the Rocky Sierra.  These mountains give rise, not merely to the Wind or Bighorn River, but to several branches of the Yellowstone and the Missouri on the east, and of the Columbia and Colorado on the west; thus dividing the sources of these mighty streams.

For five succeeding days, Mr. Hunt and his party continued up the course of the Wind River, to the distance of about eighty miles, crossing and recrossing it, according to its windings, and the nature of its banks; sometimes passing through valleys, at other times scrambling over rocks and hills.  The country in general was destitute of trees, but they passed through groves of wormwood, eight and ten feet in height, which they used occasionally for fuel, and they met with large quantities of wild flax.
