ORIGINAL AND SECONDARY CESSIONS. Another difficulty that has arisen, and one which, in order to avoid confusion, will necessitate the duplication in the atlas of the maps of several States, is the attempt to show not only original, but also secondary cessions of land. The policy followed by the United States for many years in negotiating treaties with the tribes east of the Mississippi River included the purchase of their former possessions and their removal west of that river to reservations set apart for them within the limits of country purchased for that purpose from its original owners, and which were in turn retroceded to the United States by its secondary owners. This has been largely the case in Missouri, Arkansas, Kansas, Nebraska, and Indian Territory. The present State of Kansas, for instance, was for the most part the inheritance of the Kansas and Osage tribes. It was purchased from them by the provisions of the treaties of June 2, 1825, with the Osage, and June 3, 1825, with the Kansas tribe, they, however, reserving in each case a tract sufficiently large for their own use and occupancy. These and subsequent cessions of these two tribes must be shown upon a map of "original cessions." After securing these large concessions from the Kansas and Osages, the government, in pursuance of the policy above alluded to, sought to secure the removal of the remnant of Ohio, Indiana, and Illinois tribes to this region by granting them, in part consideration for their eastern possessions, reservations therein of size and location suitable to their wishes and necessities. In this way homes were provided for the Wyandots, Delawares, Shawnees, Pottawatomies, Sacs and Foxes of the Mississippi, Kickapoos, the Confederated Kaskaskias, Peorias, Piankeshaws, and Weas, the Ottawas of Blanchard's Fork and Roche de Boeuf, and the Chippewas and Munsees. A few years of occupation again found the advancing white settlements encroaching upon their domain, with the usual accompanying demand for more land. Cessions, first; of a portion and finally of the remnant, of these reservations followed, coupled with the removal of the Indians to Indian Territory. These several reservations and cessions must be indicated upon a map of "secondary cessions." Object illustration is much, more striking and effective than mere verbal description. In order, therefore, to secure to the reader the clearest possible understanding of the subject, there is herewith presented as an illustration a map of the State of Indiana, upon which is delineated the boundaries of the different tracts of land within that State ceded to the United States from time to time by treaty with the various Indian tribes. The cessions are as follows:
