CHAPTER XXVII.
For the two following days the travellers pursued a westerly course for thirty-four miles along a ridge of country dividing the tributary waters of the Missouri and the Yellowstone. As landmarks they guided themselves by the summits of the far distant mountains, which they supposed to belong to the Big Horn chain. They were gradually rising into a higher temperature, for the weather was cold for the season, with a sharp frost in the night, and ice of an eighth of an inch in thickness.
On the twenty-second of August, early in the day, they came upon the trail of a numerous band. Rose and the other hunters examined the footprints with great attention, and determined it to be the trail of a party of Crows returning from an annual trading visit to the Mandans. As this trail afforded more commodious travelling, they immediately struck into it, and followed it for two days. It led them over rough hills, and through broken gullies, during which time they suffered great fatigue from the ruggedness of the country. The weather, too, which had recently been frosty, was now oppressively warm, and there was a great scarcity of water, insomuch that a valuable dog belonging to Mr. M'Kenzie died of thirst.
At one time they had twenty-five miles of painful travel, without a drop of water, until they arrived at a small running stream. Here they eagerly slaked their thirst; but, this being allayed, the calls of hunger became equally importunate. Ever since they had got among these barren and arid hills, where there was a deficiency of grass, they had met with no buffaloes, those animals keeping in the grassy meadows near the streams. They were obliged, therefore, to have recourse to their corn meal, which they reserved for such emergencies. Some, however, were lucky enough to kill a wolf, which they cooked for supper, and pronounced excellent food.
The next morning they resumed their wayfaring, hungry and jaded, and had a dogged march of eighteen miles among the same kind of hills. At length they emerged upon a stream of clear water, one of the forks of Powder River, and to their great joy beheld once more wide grassy meadows, stocked
