This was maintained for grazing until June 1906 when Congress passed a law that it be disposed of by allotting 160 acres, in severalty, to each child born into the tribes after the act of 1900. Remaining land was sold by sealed bid in 1906 and the proceeds placed in the U.S. Treasury. This was the last large tract of land opened for settlement in Okla. Terr.)
