After concluding the treaty with the Winnebagoes, and for the purpose of
making a lasting peace with the Sacs and Foxes, these Commissioners
held a treaty at the same place, and a week later, on the 21st day of
September, with chiefs, head men and warriors of that confederate tribe.
The Commissioners demanded, partly as indemnity for expenses incurred in
the late war with Black Hawk's band and to secure future tranquility, a
cession of a large portion of their country bordering on the frontiers.
In consideration thereof the United States agree to pay to said
confederate tribes annually, for thirty years, $20,000 in specie; also,
to pay Messrs. Farnham and Davenport, Indian traders at Rock Island, the
sum of $40,000, to be receipted for in full of all demands against
said Indians. And, further, at the special request of said confederate
tribes, the United States agree to grant, by letters patent, to their
particular friend, Antoine LeClair, interpreter, one section of land
opposite Rock Island and one section at the head of the rapids of the
Mississippi river.
