In the fall of 1837, Keokuk, Wapello, Poweshiek and forty other principal chiefs and braves traveled to Washington D.C. to meet with the U.S. Government. Col. George Davenport, who had a fair amount of influence with the Sac and Fox, traveled with the tribal members and helped negotatiate the purchase of 1.25 million acres by the U.S. On October 31, 1837 the delegation met with Carey A. Harris, Commissioner of Indian Affairs in Washington D.C. and signed the treaty. In return for the land, the United States agreed to pay all of the debts owed by the Sac and Fox to a maximum of $100,000. An additional $28,500 worth of goods chosen by the tribe were to be delivered. Two grist mills and two millers were to be provided for five years. $24,000 was allotted to plowing and fencing of land located outside of the treaty. $2,000 was budgeted for additional agricultural pursuits and $4,500 was allotted for horses and other presents to be delivered to the chiefs upon arrival at St. Louis. Lastly, $200,000 was to be invested by the government and no less than 5 percent was to be paid to the tribe annually.
