The tribe consists of four bands, which have their nestling-places in fertile, well-wooded valleys, lying among the Rocky Mountains, and watered by the Big Horse River and its tributary streams; but, though these are properly their homes, where they shelter their old people, their wives, and their children, the men of the tribe are almost continually on the foray and the scamper. They are, in fact, notorious marauders and horse-stealers; crossing and re-crossing the mountains, robbing on the one side, and conveying their spoils to the other. Hence, we are told, is derived their name, given to them on account of their unsettled and predatory habits; winging their flight, like the crows, from one side of the mountains to the other, and making free booty of everything that lies in their way. Horses, however, are the especial objects of their depredations, and their skill and audacity in stealing them are said to be astonishing. This is their glory and delight; an accomplished horse-stealer fills up their idea of a hero. Many horses are obtained by them, also, in barter from tribes in and beyond the mountains. They have an absolute passion for this noble animal; besides which he is with them an important object of traffic. Once a year they make a visit to the Mandans, Minatarees, and other tribes of the Missouri, taking with them droves of horses which they exchange for guns, ammunition, trinkets, vermilion, cloths of bright colors, and various other articles of European manufacture. With these they supply their own wants and caprices, and carry on the internal trade for horses already mentioned.
The plot of Rose to rob and abandon his countrymen when in the heart of the wilderness, and to throw himself into the hands of savages, may appear strange and improbable to those unacquainted with the singular and anomalous characters that are to be found about the borders. This fellow, it appears, was one of those desperadoes of the frontiers, outlawed by their crimes, who combine the vices of civilized and savage life, and are ten times more barbarous than the Indians with whom they consort. Rose had formerly belonged to one of the gangs of pirates who infested the islands of the Mississippi, plundering boats as they went up and down the river, and who sometimes shifted the scene of their robberies to the shore, waylaying travellers as they returned by land from New Orleans with the proceeds of their downward voyage, plundering them of their money and effects, and often perpetrating the most atrocious murders.
These hordes of villains being broken up and dispersed, Rose had betaken himself to the wilderness, and associated himself with the Crows, whose predatory habits were congenial with his own, had married a woman of the tribe, and, in short, had identified himself with those vagrant savages.
Such was the worthy guide and interpreter, Edward Rose. We give his story, however, not as it was known to Mr. Hunt and his companions at the time, but as it has been subsequently ascertained. Enough was known of the fellow and his dark and perfidious character to put Mr. Hunt upon his guard: still, as there was no knowing how far his plans might have succeeded, and as any rash act might blow the mere smouldering sparks of treason into a sudden blaze, it was thought advisable by those with whom Mr. Hunt consulted, to conceal all knowledge or suspicion of the meditated treachery, but to keep up a vigilant watch upon the movements of Rose, and a strict guard upon the horses at night.
