The Ninth Census has been completed, the report thereof published and distributed, and the working force of the Bureau disbanded. The Secretary of the Interior renews his recommendation for a census to be taken in 1875, to which subject the attention of Congress is invited. The original suggestion in that behalf has met with the general approval of the country; and even if it be not deemed advisable at present to provide for a regular quinquennial census, a census taken in 1875, the report of which could be completed and published before the one hundredth anniversary of our national independence, would be especially interesting and valuable, as showing the progress of the country during the first century of our national existence. It is believed, however, that a regular census every five years would be of substantial benefit to the country, inasmuch as our growth hitherto has been so rapid that the results of the decennial census are necessarily unreliable as a basis of estimates for the latter years of a decennial period. DISTRICT OF COLUMBIA. Under the very efficient management of the governor and the board of public works of this District the city of Washington is rapidly assuming the appearance of a capital of which the nation may well be proud. From being a most unsightly place three years ago, disagreeable to pass through in summer in consequence of the dust arising from unpaved streets, and almost impassable in the winter from the mud, it is now one of the most sightly cities in the country, and can boast of being the best paved. The work has been done systematically, the plans, grades, location of sewers, water and gas mains being determined upon before the work was commenced, thus securing permanency when completed. I question whether so much has ever been accomplished before in any American city for the same expenditures. The Government having large reservations in the city, and the nation at large having an interest in their capital, I recommend a liberal policy toward the District of Columbia, and that the Government should bear its just share of the expense of these improvements. Every citizen visiting the capital feels a pride in its growing beauty, and that he too is part owner in the investments made here. I would suggest to Congress the propriety of promoting the establishment in this District of an institution of learning, or university of the highest class, by the donation of lands. There is no place better suited for such an institution than the national capital. There is no other place in which every citizen is so directly interested. CIVIL-SERVICE REFORM. In three successive messages to Congress I have called attention to the subject of "civil-service reform."
