with herds of buffalo. For several days they kept along the banks of the river, ascending it about eighteen miles. It was a hunter's paradise; the buffaloes were in such abundance that they were enabled to kill as many as they pleased, and to jerk a sufficient supply of meat for several days' journeying. Here, then, they revelled and reposed after their hungry and weary travel, hunting and feasting, and reclining upon the grass. Their quiet, however, was a little marred by coming upon traces of Indians, who, they concluded, must be Crows; they were therefore obliged to keep a more vigilant watch than ever upon their horses. For several days they had been directing their march toward the lofty mountain described by Mr. Hunt and Mr. M'Kenzie on the 17th of August, the height of which rendered it a landmark over a vast extent of country. At first it had appeared to them solitary and detached; but as they advanced toward it, it proved to be the principal summit of a chain of mountains. Day by day it varied in form, or rather its lower peaks, and the summits of others of the chain emerged above the clear horizon, and finally the inferior line of hills which connected most of them rose to view. So far, however, are objects discernible in the pure atmosphere of these elevated plains, that, from the place where they first descried the main mountain, they had to travel a hundred and fifty miles before they reached its base. Here they encamped on the thirtieth of August, having come nearly four hundred miles since leaving the Arickara village.
The mountain which now towered above them was one of the Big Horn chain, bordered by a river of the same name, and extending for a long distance rather east of north and west of south. It was a part of the great system of granite mountains which forms one of the most important and striking features of North America, stretching parallel to the coast of the Pacific from the Isthmus of Panama almost to the Arctic Ocean, and presenting a corresponding chain to that of the Andes in the southern hemisphere. This vast range has acquired, from its rugged and broken character, and its summits of naked granite, the appellation of the Rocky Mountains, a name by no means distinctive, as ail elevated ranges are rocky. Among the early explorers it was known as the range of Chippewyan Mountains, and this Indian name is the one it is likely to retain in poetic usage. Rising from the midst of vast plains and prairies, traversing several degrees of latitude, dividing the waters of the Atlantic and the Pacific, and seeming to bind
