I confess I felt somewhat sad when I reflected upon the possible fate of the two adventurous men who had left us in the midst of a savage wilderness, to depend entirely upon their unassisted strength and hardihood, to procure the means of subsistence and repel the aggression of the Indian.

Their expedition will be fraught with stirring scenes, with peril and with strange adventure; but they think not of this, and they care not for it. They are only two of the many scores who annually subject themselves to the same difficulties and dangers; they see their friends return unscathed, and laden with rich and valuable furs, and if one or two should have perished by Indian rapacity, or fallen victims to their own daring and fool-hardy spirit, they mourn the loss of their brethren who have not returned, and are only the more anxious to pursue the same track in order to avenge them.

On the 2d, we struck a range of high and stony mountains, {66} called the Black Hills. The general aspect here, was dreary and forbidding; the soil was intersected by deep and craggy fissures; rock jutted over rock, and precipice frowned over precipice in frightful, and apparently endless, succession. Soon after we commenced the ascent, we experienced a change in the temperature of the air; and towards mid-day, when we had arrived near the summit, our large blanket capeaus,—which in the morning had been discarded as uncomfortable,—were drawn tightly around us, and every man was shivering in his saddle as though he had an ague fit. The soil here is of a deep reddish or ferruginous hue, intermixed with green sand; and on the heights, pebbles of chalcedony and agate are abundant.

We crossed, in the afternoon, the last and steepest spur of this chain, winding around rough and stony precipices, and along the extreme verges of tremendous ravines, so dangerous looking that we were compelled to dismount and lead our horses.

On descending to the plain, we saw again the north fork of the Platte, and were glad of an opportunity of encamping. Our march to-day has been an unusually wearisome one, and many of our loose horses are bruised and lame.

7th.—The country has now become more level, but the prairie is barren and inhospitable looking to the last degree. The twisted, aromatic wormwood covers and extracts the strength from the burnt and arid soil. The grass is dry and brown, and our horses are suffering extremely for want of food. Occasionally, however, a spot of lovely green appears, and here we allow our poor jaded friends to halt, and roam without their riders, and their satisfaction and pleasure is expressed by many a joyous neigh, and many a heart-felt roll upon the verdant sward.

In the afternoon, we arrived at the "Red Butes," two or three brown-red cliffs, about two thousand feet in height.[96] This is a remarkable point in the mountain route. One of these cliffs terminates a long, lofty, wooded ridge, which has bounded our {67} southern view for the past two days. The summits of the cliffs are covered with patches of snow, and the contrast of the dazzling white and brick-red produces a very pretty effect.

The next day, we left the Platte river, and crossed a wide, sandy desert, dry and desolate; and on the 9th, encamped at noon on the banks of the Sweet-water. Here we found a large rounded mass of granite, about fifty feet high, called Rock Independence.[97] Like the Red Butes, this rock is also a rather remarkable point in the route. On its smooth, perpendicular sides, we see carved the names of most of the mountain bourgeois,[98] with the dates of their arrival. We observed those of the two Sublette's, Captains Bonneville, Serre, Fontinelle, &c.,[99] and after leaving our own, and taking a hearty, but hasty lunch in the shade of a rock, and a draught from the pure and limpid stream at its base, we pursued our journey.

The river is here very narrow, often only twelve or fifteen feet wide, shallow, and winding so much, that during our march, to-day, we crossed it several times, in order to pursue a straight course. The banks of the stream are clothed with the most luxuriant pasture, and our invaluable dumb friends appear perfectly happy.

We saw here great numbers of a beautiful brown and white avocet, (the Recurvirostra americana of ornithologists.) These fine birds were so tame as to allow a very near approach, running slowly before our party, and scarcely taking wing at the report of a gun. They frequent the marshy plains in the neighborhood of the river, and breed here.
