The total number of post-offices in operation on June 30, 1873, was 33,244, a net increase of 1,381 over the number reported the preceding year. The number of Presidential offices was 1,363, an increase of 163 during the year. The total length of railroad mail routes at the close of the year was 63,457 miles, an increase of 5,546 miles over the year 1872. Fifty-nine railway post-office lines were in operation June 30, 1873, extending over 14,866 miles of railroad routes and performing an aggregate service of 34,925 miles daily. The number of letters exchanged with foreign countries was 27,459,185, an increase of 3,096,685 over the previous year, and the postage thereon amounted to $2,021,310.86. The total weight of correspondence exchanged in the mails with European countries exceeded 912 tons, an increase of 92 tons over the previous year. The total cost of the United States ocean steamship service, including $725,000 paid from special appropriations to subsidized lines of mail steamers, was $1,047,271.35. New or additional postal conventions have been concluded with Sweden, Norway, Belgium, Germany, Canada, Newfoundland, and Japan, reducing postage rates on correspondence exchanged with those countries; and further efforts have been made to conclude a satisfactory postal convention with France, but without success. I invite the favorable consideration of Congress to the suggestions and recommendations of the Postmaster-General for an extension of the free-delivery system in all cities having a population of not less than 10,000; for the prepayment of postage on newspapers and other printed matter of the second class; for a uniform postage and limit of weight on miscellaneous matter; for adjusting the compensation of all postmasters not appointed by the President, by the old method of commissions on the actual receipts of the office, instead of the present mode of fixing the salary in advance upon special returns; and especially do I urge favorable action by Congress on the important recommendations of the Postmaster-General for the establishment of United States postal savings depositories. Your attention is also again called to a consideration of the question of postal telegraphs and the arguments adduced in support thereof, in the hope that you may take such action in connection therewith as in your judgment will most contribute to the best interests of the country.
