Of he thirtyone bands treated with they were successful in making agreements with all but iour. By the terms ol the various agreements made the Indiana have been dealt with justly, ampie provisión made for their support, education and civilization, and by the cessions of land between 25,000,000 and 30,000,000 of acres of land timbered, agricultural, grazing and mineral, wiU be opened for sale and settlement, which now lies idle and unproductive.
