Legislation is desirable to render more efficient this branch of the public service. All the recommendations of the Secretary of War I regard as judicious, and I especially commend to your attention the following: The consolidation of Government arsenals; the restoration of mileage to officers traveling under orders; the exemption of money received from the sale of subsistence stores from being covered into the Treasury; the use of appropriations for the purchase of subsistence stores without waiting for the beginning of the fiscal year for which the appropriation is made; for additional appropriations for the collection of torpedo material; for increased appropriations for the manufacture of arms; for relieving the various States from indebtedness for arms charged to them during the rebellion; for dropping officers from the rolls of the Army without trial for the offense of drawing pay more than once for the same period; for the discouragement of the plan to pay soldiers by cheek, and for the establishment of a professorship of rhetoric and English literature at West Point. The reasons for these recommendations are obvious, and are set forth sufficiently in the reports attached. I also recommend that the status of the staff corps of the Army be fixed, where this has not already been done, so that promotions may be made and vacancies filled as they occur in each grade when reduced below the number to be fixed by law. The necessity for such legislation is specially felt now in the Pay Department. The number of officers in that department is below the number adequate to the performance of the duties required of them by law.

The efficiency of the Navy has been largely increased during the last year. Under the impulse of the foreign complications which threatened us at the commencement of the last session of Congress, most of our efficient wooden ships were put in condition for immediate service, and the repairs of our ironclad fleet were pushed with the utmost vigor. The result is that most of these are now in an effective state and need only to be manned and put in commission to go at once into service.

Some of the new sloops authorized by Congress are already in commission, and most of the remainder are launched and wait only the completion of their machinery to enable them to take their places as part of our effective force.

Two iron torpedo ships have been completed during the last year, and four of our large double-turreted ironclads are now undergoing repairs. When these are finished, everything that is useful of our Navy, as now authorized, will be in condition for service, and with the advance in the science of torpedo warfare the American Navy, comparatively small as it is, will be found at any time powerful for the purposes of a peaceful nation.

Much has been accomplished during the year in aid of science and to increase the sum of general knowledge and further the interests of commerce and civilization. Extensive and much-needed soundings have been made for hydrographic purposes and to fix the proper routes of ocean telegraphs. Further surveys of the great Isthmus have been undertaken and completed, and two vessels of the Navy are now employed, in conjunction with those of England, France, Germany, and Russia, in observations connected with the transit of Venus, so useful and interesting to the scientific world.

The estimates for this branch of the public service do not differ materially from those of last year, those for the general support of the service being somewhat less and those for permanent improvements at the various stations rather larger than the corresponding estimate made a year ago. The regular maintenance and a steady increase in the efficiency of this most important arm in proportion to the growth of our maritime intercourse and interests is recommended to the attention of Congress.

The use of the Navy in time of peace might be further utilized by a direct authorization of the employment of naval vessels in explorations and surveys of the supposed navigable waters of other nationalities on this continent, especially the tributaries of the two great rivers of South America, the Orinoco and the Amazon. Nothing prevents, under existing laws, such exploration, except that expenditures must be made in such expeditions beyond those usually provided for in the appropriations. The field designated is unquestionably one of interest and one capable of large development of commercial interests--advantageous to the peoples reached and to those who may establish relations with them.

Education of the people entitled to exercise the right of franchise I regard essential to general prosperity everywhere, and especially so in republics, where birth, education, or previous condition does not enter into account in giving suffrage. Next to the public school, the post-office is the great agent of education over our vast territory. The rapidity with which new sections are being settled, thus increasing the carrying of mails in a more rapid ratio than the increase of receipts, is not alarming. The report of the Postmaster-General herewith attached shows that there was an increase of revenue in his Department in 1873 over the previous year of $1,674,411, and an increase of cost of carrying the mails and paying employees of $3,041,468.91. The report of the Postmaster-General gives interesting statistics of his Department, and compares them with the corresponding statistics of a year ago, showing a growth in every branch of the Department.

A postal convention has been concluded with New South Wales, an exchange of postal cards established with Switzerland, and the negotiations pending for several years past with France have been terminated in a convention with that country, which went into effect last August.

An international postal congress was convened in Berne, Switzerland, in September last, at which the United States was represented by an officer of the Post-Office Department of much experience and of qualification for the position. A convention for the establishment of an international postal union was agreed upon and signed by the delegates of the countries represented, subject to the approval of the proper authorities of those countries.
