In his letter of transmittal “To his Excellency, Isaac I. Stevens, Governor of Washington Territory,” Mr. Denig writes: “Being stimulated with the desire to meet your wishes and forward the views of government, I have in the following pages endeavored to answer the ‘Inquiries’ published by act of Congress, regarding the ‘History, Present Condition, and Future Prospects of the Indian Tribes’ with which I am acquainted. * * * Independent of my own personal observation and knowledge acquired by a constant residence of 21 years among the prairie tribes, in every situation, I have on all occasions had the advice of intelligent Indians as to the least important of these inquiries, so as to avoid, if possible, the introduction of error. * * *
“It is presumed the following pages exhibit a minutiæ of information, on those subjects not to be obtained either by transient visitors or a residence of a few years in the country, without being, as is the case with myself, intimately acquainted with their camp regulations, understanding their language, and in many instances entering into their feelings and actions.
“The whole has been well digested, the different subjects pursued in company with the Indians for an entire year, until satisfactory answers have been obtained, and their motives of speech or action well understood before placing the same as a guide and instruction to others.
“The answers refer to the Sioux, Arikara, Mandan, Gros Ventres, Cree, Crow, Assiniboin, and Blackfeet Nations, who are designated as prairie, roving, or wild tribes—further than whom our knowledge does not extend.
“I am aware of your capacity to judge the merits of the work and will consider myself highly honored if I have had the good fortune to meet your approbation; moreover I shall rejoice if I have contributed in any degree toward opening a course of policy on the part of the Government that may result in the amelioration of the sad condition of the savages. Should the facts herein recorded ever be published or embodied in other work it is hoped the errors of language may be corrected, but in no instance is it desired that the meaning should miscarry.”
Elsewhere in this letter Mr. Denig writes: “Some of their customs and opinions now presented, although very plain and common to us who are in their daily observance, may not have been rendered in comprehensible language to those who are strangers to these things, and the number of queries, the diversity of subjects, etc., have necessarily curtailed each answer to as few words as possible.”
The report was made in response to a circular of “Inquiries, Respecting the History, Present Condition, and Future Prospects of the Indian Tribes of the United States,” by Henry R. Schoolcraft, Office of Indian Affairs, Washington, D. C., printed in Philadelphia, Pa., in 1851. This circular is a reprint of the circular issued in July, 1847, in accordance with the provisions of section 5, chapter 66, of the Laws of the Twenty-ninth Congress, second session, and approved March 3, 1847, which read, “And be it further enacted, That in aid of the means now possessed by the Department of Indian Affairs through its existing organization, there be, and hereby is, appropriated the sum of five thousand dollars to enable the said department, under the direction of the Secretary of War, to collect and digest such statistics and material as may illustrate the history, the present condition, and future prospects of the Indian tribes of the United States.”
The original circular recites that it was addressed to four classes of individuals, namely, “I. Persons holding positions under the department, who are believed to have it in their power to impart much practical information respecting the tribes who are, respectively, under their charge. II. Persons who have retired from similar situations, travelers in the Indian Territory, or partners and factors on the American frontiers. III. Men of learning or research who have perused the best writers on the subject and who may feel willing to communicate the results of their reading or reflections. IV. Teachers and missionaries to the aborigines.”
The circular closes with an expression of the “anxiety which is felt to give to the materials collected the character of entire authenticity, and to be apprised of any erroneous views in the actual manners and customs, character, and condition of our Indian tribes which may have been promulgated. The Government, it is believed, owes it to itself to originate a body of facts on this subject of an entirely authentic character, from which the race at large may be correctly judged by all classes of citizens, and its policy respecting the tribes under its guardianship, and its treatment of them, properly understood and appreciated.”
The 348 inquiries in the circular embrace the history (and archeology), the tribal organization, the religion, the manners and customs, the intellectual capacity and character, the present condition, the future prospects, and the language, of the Indian tribes of the United States.
