The Chart D shows the respective areas at one period. No very important changes took place in the delimitation of the areas during the war, and the chart may therefore be considered generally representative of the organization. Chart E shows the zones into which the Mediterranean was divided. [Transcriber's note: Charts D and E are maps of the waters around the United Kingdom, and the waters of the Mediterranean, respectively, with patrol zones marked.] In December, 1917, the number of vessels of different classes actually appropriated to various areas is given on the next page in Table A for the British Isles and Table B for the Mediterranean.
