We have only to add that the affairs of the captain have been satisfactorily arranged with the War Department, and that he is actually in service at Fort Gibson, on our western frontier, where we hope he may meet with further opportunities of indulging his peculiar tastes, and of collecting graphic and characteristic details of the great western wilds and their motley inhabitants.

We here close our picturings of the Rocky Mountains and their wild inhabitants, and of the wild life that prevails there; which we have been anxious to fix on record, because we are aware that this singular state of things is full of mutation, and must soon undergo great changes, if not entirely pass away.  The fur trade itself, which has given life to all this portraiture, is essentially evanescent.  Rival parties of trappers soon exhaust the streams, especially when competition renders them heedless and wasteful of the beaver.  The furbearing animals extinct, a complete change will come over the scene; the gay free trapper and his steed, decked out in wild array, and tinkling with bells and trinketry; the savage war chief, plumed and painted and ever on the prowl; the traders’ cavalcade, winding through defiles or over naked plains, with the stealthy war party lurking on its trail; the buffalo chase, the hunting camp, the mad carouse in the midst of danger, the night attack, the stampede, the scamper, the fierce skirmish among rocks and cliffs—­all this romance of savage life, which yet exists among the mountains, will then exist but in frontier story, and seem like the fictions of chivalry or fairy tale.

Some new system of things, or rather some new modification, will succeed among the roving people of this vast wilderness; but just as opposite, perhaps, to the inhabitants of civilization.  The great Chippewyan chain of mountains, and the sandy and volcanic plains which extend on either side, are represented as incapable of cultivation.  The pasturage which prevails there during a certain portion of the year, soon withers under the aridity of the atmosphere, and leaves nothing but dreary wastes.  An immense belt of rocky mountains and volcanic plains, several hundred miles in width, must ever remain an irreclaimable wilderness, intervening between the abodes of civilization, and affording a last refuge to the Indian.  Here roving tribes of hunters, living in tents or lodges, and following the migrations of the game, may lead a life of savage independence, where there is nothing to tempt the cupidity of the white man.  The amalgamation of various tribes, and of white men of every nation, will in time produce hybrid races like the mountain Tartars of the Caucasus.  Possessed as they are of immense droves of horses should they continue their present predatory and warlike habits, they may in time become a scourge to the civilized frontiers on either side of the mountains, as they are at present a terror to the traveller and trader.

The facts disclosed in the present work clearly manifest the policy of establishing military posts and a mounted force to protect our traders in their journeys across the great western wilds, and of pushing the outposts into the very heart of the singular wilderness we have laid open, so as to maintain some degree of sway over the country, and to put an end to the kind of “blackmail,” levied on all occasions by the savage “chivalry of the mountains.”
