THE NORTHERN BOUNDARY LINE OF THE REMAINING INDIAN COUNTRY
The treaty of 16 October 1826 took the county's northwest quarter and fixed the line the 1832 treaty would start from. This section tests it the way the 1832 instrument itself frames it: the Tippecanoe boundary of 1832 runs, in its own words, along "the southern boundary of the cession made by the treaty of 1826" for the whole of its northern reach at this longitude. The townsite lies inside the 1832 polygon, south of that line; it was therefore still Indian country when the 1826 treaty closed — which is exactly Howard's assignment of the northwest quarter to 1826 and the southwest to 1832, tested here from the later treaty's own recital rather than from the county history's word. The 1826 cession is a negative for this ground, and a necessary one: it is the line that proves the ground was unceded, and still possessed, six years before the taking.
