An historical atlas of Indian affairs has for some time past been in course of preparation under the direction of the Bureau of Ethnology, Smithsonian Institution. The chief aim of this atlas is to show upon a series of State and Territorial maps the boundaries of the various tracts of country which have from time to time been acquired through the medium of treaty stipulation or act of Congress from the several Indian tribes resident within the present territory of the United States from the beginning of the Federal period to the present day. Accompanying this atlas will be one or more volumes of historical text, wherein will be given with some detail a history of the official relations between the United States and these tribes. This will treat of the various negotiations for peace and for the acquisition of territory, the causes rendering such negotiations necessary, and the methods observed by the Government through its authorized agents in this diplomacy, as well as other matters of public concern growing out of the same. The following monograph on the history of the Cherokees, with its accompanying maps, is given as an illustration of the character of the work in its treatment of each of the Indian tribes. The maps are intended to show not only the ancestral but the present home of the Cherokees, and also to indicate the boundaries of the various tracts of territory purchased from them by the Colonial or Federal authorities from time to time since their first contact with the European settlements. A number of purchases made prior to the Federal period by individuals were unauthorized and unrecognized by the Colonial authorities, and their boundaries, though given in the text, are not laid down upon the map, because the same areas of territory were afterwards included within the limits of Colonial purchases. In the preparation of this article, more particularly in the tracing out of the various boundary lines, much careful attention and research have been given to all available authorities or sources of information. The old manuscript records of the Government, the shelves of the Congressional Library, including its very large collection of American maps, local records, and the knowledge of "old settlers," as well as the accretions of various State historical societies, have been made to pay tribute to the subject. In the course of these researches the writer has been met in his inquiries with a degree of courtesy and kindly assistance that merits public recognition.
