I again commend the general interests of the District of Columbia to the favorable consideration of Congress. The affairs of the District, as shown by the report of the Commissioners, are in a very satisfactory condition. In my annual messages heretofore and in my special message of December 19, 1879, I have urged upon the attention of Congress the necessity of reclaiming the marshes of the Potomac adjacent to the capital, and I am constrained by its importance to advert again to the subject. These flats embrace an area of several hundred acres. They are an impediment to the drainage of the city and seriously impair its health. It is believed that with this substantial improvement of its river front the capital would be in all respects one of the most attractive cities in the world. Aside from its permanent population, this city is necessarily the place of residence of persons from every section of the country engaged in the public service. Many others reside here temporarily for the transaction of business with the Government. It should not be forgotten that the land acquired will probably be worth the cost of reclaiming it and that the navigation of the river will be greatly improved. I therefore again invite the attention of Congress to the importance of prompt provision for this much needed and too long delayed improvement. The water supply of the city is inadequate. In addition to the ordinary use throughout the city, the consumption by Government is necessarily very great in the navy-yard, arsenal, and the various Departments, and a large quantity is required for the proper preservation of the numerous parks and the cleansing of sewers. I recommend that this subject receive the early attention of Congress, and that in making provision for an increased supply such means be adopted as will have in view the future growth of the city. Temporary expedients for such a purpose can not but be wasteful of money, and therefore unwise. A more ample reservoir, with corresponding facilities for keeping it filled, should, in my judgment, be constructed. I commend again to the attention of Congress the subject of the removal from their present location of the depots of the several railroads entering the city; and I renew the recommendations of my former messages in behalf of the erection of a building for the Congressional Library, the completion of the Washington Monument, and of liberal appropriations in support of the benevolent, reformatory, and penal institutions of the District.
