Fourth. The trial with torpedoes under the Corps of Engineers, and appropriation for the same. Should war ever occur between the United States and any maritime power, torpedoes will be among if not the most effective and cheapest auxiliary for the defense of harbors, and also in aggressive operations, that we can have. Hence it is advisable to learn by experiment their best construction and application, as well as effect.

Fifth. A permanent organization for the Signal-Service Corps. This service has now become a necessity of peace as well as war, under the advancement made by the present able management.

Sixth. A renewal of the appropriation for compiling the official records of the war, etc.

The condition of our Navy at this time is a subject of satisfaction. It does not contain, it is true, any of the powerful cruising ironclads which make so much of the maritime strength of some other nations, but neither our continental situation nor our foreign policy requires that we should have a large number of ships of this character, while this situation and the nature of our ports combine to make those of other nations little dangerous to us under any circumstances.

Our Navy does contain, however, a considerable number of ironclads of the monitor class, which, though not properly cruisers, are powerful and effective for harbor defense and for operations near our own shores. Of these all the single-turreted ones, fifteen in number, have been substantially rebuilt, their rotten wooden beams replaced with iron, their hulls strengthened, and their engines and machinery thoroughly repaired, so that they are now in the most efficient condition and ready for sea as soon as they can be manned and put in commission.

The five double-turreted ironclads belonging to our Navy, by far the most powerful of our ships for fighting purposes, are also in hand undergoing complete repairs, and could be ready for sea in periods varying from four to six months. With these completed according to the present design and our two iron torpedo boats now ready, our ironclad fleet will be, for the purposes of defense at home, equal to any force that can readily be brought against it.

Of our wooden navy also cruisers of various sizes, to the number of about forty, including those now in commission, are in the Atlantic, and could be ready for duty as fast as men could be enlisted for those not already in commission. Of these, one-third are in effect new ships, and though some of the remainder need considerable repairs to their boilers and machinery, they all are, or can readily be made, effective.

This constitutes a fleet of more than fifty war ships, of which fifteen are ironclad, now in hand on the Atlantic coast. The Navy has been brought to this condition by a judicious and practical application of what could be spared from the current appropriations of the last few years and from that made to meet the possible emergency of two years ago. It has been done quietly, without proclamation or display, and though it has necessarily straitened the Department in its ordinary expenditure, and, as far as the ironclads are concerned, has added nothing to the cruising force of the Navy, yet the result is not the less satisfactory because it is to be found in a great increase of real rather than apparent force. The expenses incurred in the maintenance of an effective naval force in all its branches are necessarily large, but such force is essential to our position, relations, and character, and affects seriously the weight of our principles and policy throughout the whole sphere of national responsibilities.

The estimates for the regular support of this branch of the service for the next year amount to a little less in the aggregate than those made for the current year; but some additional appropriations are asked for objects not included in the ordinary maintenance of the Navy, but believed to be of pressing importance at this time. It would, in my opinion, be wise at once to afford sufficient means for the immediate completion of the five double-turreted monitors now undergoing repairs, which must otherwise advance slowly, and only as money can be spared from current expenses. Supplemented by these, our Navy, armed with the destructive weapons of modern warfare, manned by our seamen, and in charge of our instructed officers, will present a force powerful for the home purposes of a responsible though peaceful nation.

The report of the Postmaster-General herewith transmitted gives a full history of the workings of the Department for the year just past. It will be observed that the deficiency to be supplied from the General Treasury is increased over the amount required for the preceding year. In a country so vast in area as the United States, with large portions sparsely settled, it must be expected that this important service will be more or less a burden upon the Treasury for many years to come. But there is no branch of the public service which interests the whole people more than that of cheap and rapid transmission of the mails to every inhabited part of our territory. Next to the free school, the post-office is the great educator of the people, and it may well receive the support of the General Government.
