Report of the Committee on Naval Affairs, who were instructed, by a resolution of the House of Representatives, to inquire into the expediency of so modifying the act establishing a Board of Commissioners of the Navy, as to make the Secretary of the Navy, for the time being, the presiding officer of that Board; and, also, of so limiting the tenor of the commissions to the members thereof, as to secure the accumulating experience and talents of our naval commanders in that Department, by a periodical rotation in office.
