Shall there be one general reservation east of the Rocky Mountains, or two? This is likely to be the most important Indian question of the immediate future. On the one hand, the recommendations of the executive, contained in both the Messages of the President and the Annual Reports of the Secretary of the Interior, for the past two or three years, have strongly favored the plan of a single reservation for all the tribes, North and South, East and West, who are not in a condition to become at an early day citizens of the United States and take their land in severalty. The reservation upon which it is proposed to thus collect the Indians of the United States is at present known as the "Indian Territory," although it actually contains but about one-quarter of the Indian population of the country. This tract covers all the territory lying between the States of Arkansas and Missouri on the east, and the one-hundredth meridian on the west, and between the State of Kansas on the north, and the Red River, the boundary of the State of Texas, on the south; comprising about seventy thousand square miles, and embracing a large body of the best agricultural lands west of the Mississippi. Upon this tract, it is claimed, can be gathered and subsisted all the Indians within the administrative control of the government, except such as are manifestly becoming ripe for citizenship in the States and Territories where they are now found. Computing the maximum number likely, on the successful realization of this scheme to be thus concentrated, at two hundred and fifty thousand, and taking the available lands within the district, exclusive of barren plains, of flint hills and sand hills, at an aggregate of thirty million acres, we should have one hundred and twenty acres for each man, woman, and child to be provided for.
