A few weeks since D. D. Mitchell, Esq., a resident for many years past, near the falls of Missouri, in the vicinity of the Rocky Mountains, was in this city, on a visit to his native State, and it was my good fortune to become personally acquainted with him. He has been an enterprising and successful adventurer in the American fur trade, and is now in command of a fort and trading establishment in the neighborhood of the _Black-feet_, a nation of Indians with whom the whites have had but little intercourse, and whose peculiar character and manners we have had few opportunities of knowing. Besides being a bold and active participator in many of the bloody conflicts of various tribes, Mr. Mitchell has been a keen observer of Indian customs, traits, and superstitions; and so great a favorite was he among the powerful tribe of the Black-feet, that they created him a chief, with the title of the _Spotted Elk_. Mr. Mitchell did me the favor whilst here, to submit some of his manuscripts to my inspection. They contain sketches of the Indian character, and of the country, on the head waters of Missouri, hitherto almost unexplored by the white man, and also various interesting anecdotes and observations, highly creditable to the intelligence, discernment and enterprise of the writer. I cannot withhold from the patrons of the Literary Messenger, some share of the pleasure I have myself experienced, in reading these valuable papers, and, for the present, I send to the publisher, a remarkable Indian love tale, which Mr. Mitchell, besides his written testimony, privately assured me was _founded on fact_.--Washington Irving, in his recent "Tour on the Prairies," makes the following remark: "As far as I can judge, the Indian of poetical fiction, is like the shepherd of pastoral romance, a mere personification of imaginary attributes." It may be so, and perhaps most heroes and heroines of novels and romances, are principally creations of fancy; but if the author of the Sketch Book, meant to assert, that the children of the forest were altogether unsusceptible of some of the noble and tender emotions of our nature--he stands opposed by undoubted evidence to the contrary. Who does not believe, for example, what our own history has taught, of the matchless purity and guileless simplicity of Pocahontas--the lofty spirit of Totopotomoi, and the rare magnanimity of Logan? The passion of love indeed, as modified and refined in civilized life, has not often been found in the breast of the Indian warrior, but even to this general truth, there have been numerous exceptions, and among them, I have never met with one so marked and striking, as that which is recorded in the following story.
