INDIAN TRIBES OF THE MISSOURI VALLEY. 457 
N OT E. 
THE materials composing this memoir have been accumulated during several expeditions to the Northwest since 
1855. A considerable portion of the information in regard to the history of the Indian tribes was obtained during 
the years 1854 and ’55, while the author was exploring the Valley of the Missouri River, under the patronage 
and protection of the American Fur Company. The greater part, however, was secured in 1856 and ’57, while 
under the command of Lieut. G. K. Warren, T. H. U. S. A., and in the years 1859 and ’60, while attached to 
the Exploring Expedition to the head waters of the Missouri and Yellowstone, under the command of Capt. 
William F. Raynolds, T. H. U.S. A. From both Lieut. Warren and Capt. Raynolds, the author cheerfully 
acknowledges great aid and encouragement in his researches. The results have been prepared and published in 
their present form by permission of the War Department. 
The proof-sheets have been read with great care by a very critical philologist, Mr. Pliny E. Chase, of Philadel- 
phia, and for his kindness and courtesy in this matter, the author gladly acknowledges his indebtedness. 
EXPLANATION OF PLATES AND MAP. 
The plates of Indian portraits were added to the memoir at the suggestion of an eminent ethnologist after the 
paper was completed, and this will account for the absence of any allusion to them in the text. It was a favorite 
desion of the late lamented Prof. W. W. Turner, to prepare a work on the Indian languages of America, accompa- 
nied with portraits, so far as they could be secured, of the Indians from whom the vocabularies were obtained, 
showing the mental status of the man, as the representative of his tribe or language. So far as possible I have 
adopted this plan in the present memoir. The figures on the plates accompanying this work are copied from photo- 
_ graphs taken in the Indian country, under the direction of Mr. J. D. Hutton, Topographical Assistant to Capt. 
William F. Raynolds, T. H., and published by permission of the latter. They are quite characteristic of the 
tribes they represent. 
Fie. 1, Plate I, represents one of the most noted Crow chiefs, who wields great influence in his tribe, is a fine 
orator, and possessed of strong native talents. From him [I obtained much reliable information in regard to the 
history and the language of the Crow tribe. Fa. 2 isa Shyenne brave, an excellent hunter, with fine natural 
powers, quick perceptions and intelligence, increased by long association with the whites. He formed the medium 
through which I obtained all the materials in regard to the Shyennes and their language. He is alluded to in the 
text under the name of “Rib,” on page 276. Fuia. 3 is the portrait of ‘Iron Horn,” one of the most noted 
medicine-men in the Dakota nation. He possesses great influence in his tribe, is a warm friend of the whites, 
and has done much to harmonize difficulties among his people. He has often acted as guide and hunter to United 
States Exploring parties in the Dakota country. Fa. 4 represents the daughter of a late chief of one of the 
principal bands of the Dakota nation, and is now the wife of Mr. Charles E. Galpin, one of the chief partners in the 
American Fur Company. She is a woman of much intelligence and fine natural capacities, and may be regarded 
as the highest type of her sex among the Indian tribes of the Northwest. 
Fic. 5, Plate Il, is a Crow Indian of the more common sort, somewhat below the average grade. Fic. 6 
represents one of the most influential chiefs of the Yancton band of the Dakotas, “Smutty Bear,” as his Indian
