It has never been our policy to maintain large standing armies in time of peace. They are contrary to the genius of our free institutions, would impose heavy burdens on the people and be dangerous to public liberty. Our reliance for protection and defense on the land must be mainly on our citizen soldiers, who will be ever ready, as they ever have been ready in times past, to rush with alacrity, at the call of their country, to her defense. This description of force, however, can not defend our coast, harbors, and inland seas, nor protect our commerce on the ocean or the Lakes. These must be protected by our Navy. Considering an increased naval force, and especially of steam vessels, corresponding with our growth and importance as a nation, and proportioned to the increased and increasing naval power of other nations, of vast importance as regards our safety, and the great and growing interests to be protected by it, I recommend the subject to the favorable consideration of Congress. The report of the Postmaster-General herewith communicated contains a detailed statement of the operations of his Department during the past year. It will be seen that the income from postages will fall short of the expenditures for the year between $1,000,000 and $2,000,000. This deficiency has been caused by the reduction of the rates of postage, which was made by the act of the 3d of March last. No principle has been more generally acquiesced in by the people than that this Department should sustain itself by limiting its expenditures to its income. Congress has never sought to make it a source of revenue for general purposes except for a short period during the last war with Great Britain, nor should it ever become a charge on the general Treasury. If Congress shall adhere to this principle, as I think they ought, it will be necessary either to curtail the present mail service so as to reduce the expenditures, or so to modify the act of the 3d of March last as to improve its revenues. The extension of the mail service and the additional facilities which will be demanded by the rapid extension and increase of population on our western frontier will not admit of such curtailment as will materially reduce the present expenditures. In the adjustment of the tariff of postages the interests of the people demand that the lowest rates be adopted which will produce the necessary revenue to meet the expenditures of the Department. I invite the attention of Congress to the suggestions of the Postmaster-General on this subject, under the belief that such a modification of the late law may be made as will yield sufficient revenue without further calls on the Treasury, and with very little change in the present rates of postage. Proper measures have been taken in pursuance of the act of the 3d of March last for the establishment of lines of mail steamers between this and foreign countries. The importance of this service commends itself strongly to favorable consideration.
