In time of peace we have need of no more ships of war than are requisite to the protection of our commerce. Those not wanted for this object must lay in the harbors, where without proper covering they rapidly decay, and even under the best precautions for their preservation must soon become useless. Such is already the case with many of our finest vessels, which, though unfinished, will now require immense sums of money to be restored to the condition in which they were when committed to their proper element. On this subject there can be but little doubt that our best policy would be to discontinue the building of ships of the first and second class, and look rather to the possession of ample materials, prepared for the emergencies of war, than to the number of vessels which we can float in a season of peace, as the index of our naval power. Judicious deposits in navy-yards of timber and other materials, fashioned under the hands of skillful workmen and fitted for prompt application to their various purposes, would enable us at all times to construct vessels as fast as they can be manned, and save the heavy expense of repairs, except to such vessels as must be employed in guarding our commerce. The proper points for the establishment of these yards are indicated with so much force in the report of the Navy Board that in recommending it to your attention I deem it unnecessary to do more than express my hearty concurrence in their views. The yard in this District, being already furnished with most of the machinery necessary for shipbuilding, will be competent to the supply of the two selected by the Board as the best for the concentration of materials, and, from the facility and certainty of communication between them, it will be useless to incur at those depots the expense of similar machinery, especially that used in preparing the usual metallic and wooden furniture of vessels. Another improvement would be effected by dispensing altogether with the Navy Board as now constituted, and substituting in its stead bureaus similar to those already existing in the War Department. Each member of the Board, transferred to the head of a separate bureau charged with specific duties, would feel in its highest degree that wholesome responsibility which can not be divided without a far more than proportionate diminution of its force. Their valuable services would become still more so when separately appropriated to distinct portions of the great interests of the Navy, to the prosperity of which each would be impelled to devote himself by the strongest motives. Under such an arrangement every branch of this important service would assume a more simple and precise character, its efficiency would be increased, and scrupulous economy in the expenditure of public money promoted.
