MR. PRESIDENT,--The Committee on Naval Affairs have the responsibility of shaping some measure by which the relations of our Government with the ocean steamers will be defined. And since one special inducement to these relations, involving the bounty now enjoyed and further solicited, is the carrying of the mails, I trust this Committee will be willing to inquire whether there cannot be a reduction on the postage of foreign correspondence. Under the Postage Act of 1851, the Postmaster, by and with the advice of the President, has power to reduce, from time to time, the rates of postage on all mailable matter conveyed between the United States and any foreign country. But the existence of this power in the Postmaster will not render it improper for the Committee, now drawn into connection with this question, to take it into careful consideration, with a view to some practical action, or, at least, recommendation. The subject is of peculiar interest; nor do I know any measure, so easily accomplished, which promises to be so beneficent as cheap ocean postage. The argument in its favor is at once brief and unanswerable. A letter can be sent three thousand miles in the United States for three cents, and the reasons for cheap postage on land are equally applicable to ocean. In point of fact, the conveyance of letters can be effected in sailing or steam packets at less cost than by railway. Besides, cheap ocean postage will tend to supersede the clandestine or illicit conveyance of letters, and to bring into the mails all mailable matter, which, under the present system, is carried in the pockets of passengers or in the bales and boxes of merchants. All new facilities for correspondence naturally give new expansion to human intercourse; and there is reason to believe, that, through an increased number of letters, cheap ocean postage will be self-supporting. Cheap postal communication with foreign countries will be of incalculable importance to the commerce of the United States. By promoting the intercourse of families and friends separated by ocean, cheap postage will add to the sum of human happiness. The present high rates of ocean postage--namely, twenty-four cents on half an ounce, forty-eight cents on an ounce, and ninety-six cents on a letter which weighs a fraction more than an ounce--are a severe tax upon all, particularly upon the poor, amounting, in many cases, to a complete prohibition of foreign correspondence. This should not be. It particularly becomes our country, by the removal of all unnecessary burdens upon foreign correspondence, to advance the comfort of European emigrants seeking a home among us, and to destroy, as far as practicable, every barrier to free intercourse between the Old World and the New. And, lastly, cheap ocean postage will be a bond of peace among the nations of the earth, and will extend good-will among men.
