We occupied the entire day in ascending and crossing the ridge of land, which divides the little valley of the Oza from that of the Merrimack. When getting near the latter, the soil exhibited traces of what appeared to be iron ore, but somewhat peculiar in its character, and of dark hue. This soon revealed itself, in passing a short distance, in an abundant locality of black and coloured oxide of manganese--lying in masses in the arid soil. The Indian trail which we were pursuing led across the valley. We forded the river on foot. No encampments of Indians were found, nor any very recent traces of them; and we began to think that the accounts of Osage depredations and plundering, must be rather exaggerated. The river pours its transparent mountain waters over a wide bed of pebbles and small boulders, and, at this season, offered but little impediment to the horses or ourselves in crossing it. The sun was getting low, by the time we reached the opposite side of the valley, and we encamped on its borders, a mile or two above. Here we took due care of our horses, prepared our evening's meal, talked over the day's adventures, enjoyed ourselves sitting before our camp fire, with the wild wide creation before us and around, and then sank to a sound repose on our pallets. Novices in the woodman's art, and raw in the business of travelling, our sleep was sounder and more death-like, than that of Roberts. His eye had shown a restlessness during the afternoon and evening. We were now in a game country, the deer and elk began to be frequently seen, and their fresh tracks across our path, denoted their abundance. During the night they ventured about our camp, so as to disturb the ears of the weary hunter, and indeed, my own. He got up and found both horses missing. Butcher's memory of Mine a Burton corn fodder had not deserted him, and he took the hunter's horse along with him. I jumped up, and accompanied him, in their pursuit. They were both overtaken about three miles back on the track, making all possible speed homeward, that their tethered fore legs would permit. We conducted them back, without disturbing my companion, and he then went out with his rifle, and quickly brought in a fine fat doe, for our breakfast. Each one cut fine pieces of steaks, and roasted for himself. We ate it with a little salt, and the remainder of the hunter's corn cakes, and finished the repast, with a pint cup each, of Enobitti's best tea. This turned out to be _a finale_ meal with our Fourche a Courtois man, Roberts: for the rascal, a few hours afterwards, deserted us, and went back. Had he given any intimation of dissatisfaction, or a desire to return, we should have been in a measure prepared for it. It is probable his fears of the then prevalent bugbear of those frontiersmen, the Osages, were greater than our own. It is also probable, that he had no other idea whatever, in leaving the Fourche a Courtois, than to avail himself of our protection till he could get into
