Section.
The portion of the organization under the A.C.N.S.

comprised the following numbers in December, 1917: Mercantile Movements Division, 36 Officers, with a clerical staff.
Trade Division, 43 Officers, with a clerical staff of 10 civilians.
Anti-Submarine Division, 26 Officers, with a clerical staff.
Mine-Sweeping Division, 8 Officers, with a clerical staff.
Of this number practically the whole of the Mercantile Movements and Anti-Submarine Divisions were added during the year 1917, whilst large additions were also made to the Trade Division, owing to the great increase of work.
During the first half of the year 1917 the Operations Division of the Naval Staff received a much needed increase of strength by the appointment of additional officers, charged, under the Director of the Operations Division, with the detailed preparation of plans for operations.
