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.
