I communicate herewith a report from the Secretary of the Treasury, transmitting a report from the Commissioner of Public Lands in reply to the resolution of the Senate of the 22d of June, 1846, calling for information of the "progress which has been made in the surveys of the mineral region upon Lake Superior, and within what time such surveys may probably be prepared for the sales of the lands in that country." In answer to that portion of the resolution which calls for the "views" of the Executive "respecting the proper mode of disposing of said lands, keeping in view the interest of the United States and the equitable claims of individuals who, under the authority of the War Department, have made improvements thereon or acquired rights of possession," I recommend that these lands be brought into market and sold at such price and under such regulations as Congress may prescribe, and that the right of preemption be secured to such persons as have, under the authority of the War Department, made improvements or acquired rights of possession thereon. Should Congress deem it proper to authorize the sale of these lands, it will be necessary to attach them to suitable land districts, and that they be placed under the management and control of the General Land Office, as other public lands. JAMES K. POLK. WASHINGTON, _July 11, 1846_. _To the Senate of the United States_. I communicate herewith a report from the Secretary of War, together with copies of the reports of the board of engineers heretofore employed in an examination of the coast of Texas with a view to its defense and improvement, called for by the resolution of the 29th June, 1846. JAMES K. POLK. WASHINGTON, _July 15, 1846_. _To the Senate of the United States_: I transmit herewith, for the consideration of the Senate, a treaty concluded on the 15th day of May last with the Comanche and other tribes or bands of Indians of Texas and the Southwestern prairies. I also inclose a communication from the Secretary of War and a report from the Commissioner of Indian Affairs, with accompanying documents, which contain full explanations of the considerations which led to the negotiation of the treaty and the general objects sought to be accomplished by it. JAMES K. POLK. WASHINGTON, _July 21, 1846_. _To the Senate of the United States_:
