11.  Two cessions were made by the Chippewas, Ottawas and Pottawatomies by treaty of July 29, 1829 (partly located in Wisconsin), one of which is entirely and the other largely within the limits of the country previously ceded by the Sacs and Foxes, November 3, 1804.

12.  The Winnebago cession of August 1, 1829 (which is partly in Wisconsin), is also wholly within the limits of the aforesaid Sac and Fox cession of 1804.

13.  Cession by the Winnebagoes September 15, 1832, which is mostly in the State of Wisconsin and which was also within the limits of the Sac and Fox cession of 1804.

14.  Pottawatomie cession of October 20, 1832, which overlaps the Kaskaskia and Peoria cession of August 13, 1803, as confirmed and enlarged September 25, 1818, and also the Kickapoo cession by treaties of July 30 and August 30, 1819.

From this it will be seen that almost the entire country comprising the present State of Illinois was the subject of controversy in the matter of original ownership, and that the United States, in order fully to extinguish the Indian claim thereto, actually bought it twice, and some portions of it three times.  It is proper, however, to add in this connection that where the government at the date of a purchase from one tribe was aware of an existing claim to the same region by another tribe, it had the effect of diminishing the price paid.

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.”
