The recommendations heretofore made for a partial reorganization of the Army are also renewed. The thorough elementary education given to those officers who commenced their service with the grade of cadet qualifies them to a considerable extent to perform the duties of every arm of the service; but to give the highest efficiency to artillery requires the practice and special study of many years, and it is not, therefore, believed to be advisable to maintain in time of peace a larger force of that arm than can be usually employed in the duties appertaining to the service of field and siege artillery. The duties of the staff in all its various branches belong to the movements of troops, and the efficiency of an army in the field would materially depend upon the ability with which those duties are discharged. It is not, as in the case of the artillery, a specialty, but requires also an intimate knowledge of the duties of an officer of the line, and it is not doubted that to complete the education of an officer for either the line or the general staff it is desirable that he shall have served in both. With this view, it was recommended on a former occasion that the duties of the staff should be mainly performed by details from the line, and, with conviction of the advantages which would result from such a change, it is again presented for the consideration of Congress. The report of the Secretary of the Navy, herewith submitted, exhibits in full the naval operations of the past year, together with the present condition of the service, and it makes suggestions of further legislation, to which your attention is invited. The construction of the six steam frigates for which appropriations were made by the last Congress has proceeded in the most satisfactory manner and with such expedition as to warrant the belief that they will be ready for service early in the coming spring. Important as this addition to our naval force is, it still remains inadequate to the contingent exigencies of the protection of the extensive seacoast and vast commercial interests of the United States. In view of this fact and of the acknowledged wisdom of the policy of a gradual and systematic increase of the Navy an appropriation is recommended for the construction of six steam sloops of war. In regard to the steps taken in execution of the act of Congress to promote the efficiency of the Navy, it is unnecessary for me to say more than to express entire concurrence in the observations on that subject presented by the Secretary in his report.
