I take this occasion to invite the early attention of Congress to the continuation of the work on the Mississippi River which is being carried on under the plans of the commission. My sense of the importance of the improvement of this river, not only to the people of the Northwest, but especially to the inhabitants of the Lower Mississippi Valley, has already been expressed in a special communication to the last Congress. The harvests of grain and cotton produced in the region bordering upon the Mississippi are so vast as to be of national importance, and the project now being executed for their cheap transportation should be sufficiently provided for. The commission report that the results due to the still uncompleted works have been remarkable, and give the highest encouragement for expecting the ultimate success of the improvement. The act of August 2, 1882, appropriated $4,123,000 for the work on that part of the river below Cairo. The estimates of the commission already transmitted to Congress call for $3,000,000 for the continuation of the work below Cairo, and it appears from their report that all of the last appropriation available for active operations has been exhausted and that there is urgently needed an immediate appropriation of $1,000,000 to continue the work without loss of time, in view of the approach of the flood season, with its attendant dangers. I therefore recommend to Congress the early passage of a separate bill on this subject. CHESTER A. ARTHUR. EXECUTIVE MANSION, _January 9, 1884_. _To the Senate and House of Representatives:_ I transmit herewith, for the consideration of Congress, a letter from the Secretary of War of the 7th instant, inclosing a copy of one from the Quartermaster-General of the Army submitting plans and estimates for the construction of walls, etc., at the Schuylkill Arsenal, Philadelphia, Pa., rendered necessary by the opening of Peltz street, and recommending that an appropriation be made of the amount estimated to be requisite for the work referred to. CHESTER A. ARTHUR. EXECUTIVE MANSION, _January 14, 1884_. _To the Senate and House of Representatives:_ I transmit herewith a communication from the Secretary of the Interior, submitting, with accompanying papers, an estimate of appropriation in the sum of $25,000 for the settlement under existing treaties of certain freedmen and their descendants upon lands known as the Oklahoma district, within the Indian Territory. The matter is presented for the consideration of the Congress. CHESTER A. ARTHUR. EXECUTIVE MANSION, _January 14, 1884_. _To the Senate and House of Representatives:_
