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.
