These bureaus are seven in number: Yards and Docks, Navigation, Ordnance, Construction and Repairs, Steam Engineering, Supplies and Accounts, and Medicine and Surgery. The Chief of Naval Operations, whose office was created in 1915, stands second to the Secretary and acts as his expert professional adviser, with the specific task of co-ordinating the work of the navy, preparing plans, and directing operations in war. He is, ex officio, a member of the General Board of the Navy, created in 1900, which serves as an expert advisory body.—Editor.
