TO GOVERNOR HARRISON.
Washington, December 22, 1808.
Sir,—By the treaty of 1803, we obtained from the Kaskaskias the country as far as the ridge dividing the waters of the Kaskaskias from those of the Illinois River; by the treaty of 1804, with the Sacs and Foxes, they ceded to us from the Illinois to the Ouisconsin. Between these two cessions is a gore of country, to wit, between the Illinois River and Kaskaskias line, which I understand to have belonged to the Piorias, and that that tribe is now extinct; if both these facts be true, we succeed to their title by our being proprietors paramount of the whole country. In this case it is interesting to settle our boundary with our next neighbors the Kickapoos. Where their western boundary is, I know not; but they cannot come lower down the Illinois River than the Illinois Lake, on which stood the old Pioria fort, and perhaps not so low. The Kickapoos are bounded to the south-east, I presume, by the ridge between the waters of the Illinois and Wabash, to which the Miamis claim, and north-east by the Pottewatamies. Of course it is with the Kickapoos alone we have to settle a boundary. I would therefore recommend to you to take measures for doing this. You will of course first endeavor with all possible caution to furnish yourself with the best evidence to be had, of the real location of the south-west boundary of the Kickapoos, and then endeavor to bring them to an acknowledgment of it formally, by a treaty of limits. If it be nothing more, the ordinary presents are all that will be necessary, but if they cede a part of their own country, then a price proportioned will be proper. In a letter to you of February 27th, 1803, I mentioned that I had heard there was still one Pioria man living, and that a compensation making him easy for life should be given him, and his conveyance of the country by a regular deed be obtained. If there be such a man living, I think this should still be done. The ascertaining the line between the Kickapoos and us is now of importance, because it will close our possessions on the hither bank of the Mississippi from the Ohio to the Ouisconsin, and give us a broad margin to prevent the British from approaching that river, on which, under color of their treaty, they would be glad to hover, that they might smuggle themselves and their merchandise into Louisiana. Their treaty can only operate on the country so long as it is Indian; and in proportion as it becomes ours exclusively, their ground is narrowed. It makes it easier too for us to adopt on this side of the Mississippi a policy we are beginning on the other side, that of permitting no traders, either ours or theirs, to go to the Indian towns, but oblige them all to settle and be stationary at our factories, where we can have their conduct under our observation and control. However, our first object must be to blockade them from the Mississippi, and to this I ask the favor of your attention; and salute you with great friendship and respect.
