This treaty allowed the U. S. government to create a road connecting the western portion of Missouri to New Mexico (which was still in the hands of Mexico at this time). The treaty goes into some detail about the specifications for this road. It bears the signature of ten Kansa leaders and three Indian commissioners, included George Sibley. Attached to the back of the treaty is a travel pass for the "bearer of this, a Kansas Indian," allowing him undisturbed passage and requesting that he be provided with any necessary supplies. The document is dated August 16, 1825, but the note on the back is dated 1845.
