(_a_) _Coastal Districts in France._--The north and west coasts of France are divided into districts which correspond with the French prefectures maritimes, and the district headquarters are in every case located in the same place as those of the several prefects maritimes. These headquarters are communication and operating centers and provide naturally by arrangement as above described for full and ready cooperation with the French district activities. [Sidenote: Port officers.] (_b_) The principal ports have assigned to them a port officer whose function in regard to all United States ships is to expedite their "turn around," and in addition, where vessels carrying United States naval armed guards are concerned, to inspect the armed guards and adjust such matters as are beyond the capacity or authority of the armed guard commander. (_a_) _United States Naval Aviation in France_ includes all that the title implies, except the northern bombing group mentioned above, and aviation matters are immediately in the hands of Captain T.T. Craven, aid for aviation on Vice Admiral Wilson's staff. [Sidenote: Stations for seaplanes, dirigibles and balloons.] (_b_) There are eight sea-plane stations, three dirigible stations, and three kite-balloon stations, all of which are operated by district commanders in cooperation with the French naval air services in the several corresponding prefectures maritimes. There is also an assembly, repair, and supply base at Pauillac for the general service of all air stations in France and a sea-plane gunnery and bombing training school at Moutchie, both of these activities being directly under the headquarters in Brest. (_c_) Of the eight seaplane stations, five have been in operation for periods varying from 12 to 3 months, and the remaining 3 are now about ready to begin. (_d_) Of the three dirigible stations, only that at Paimboeuf has been in operation for any length of time, and is to be used also for training and experimental work. The station at Guipavas will shortly be in operation. The station at Gujan has been delayed to let material go to other stations which it was deemed advisable to complete first. [Sidenote: Experimental balloon work at Brest.] (_e_) Of the three kite-balloon stations, only that at Brest is ready for operation. Test and experimental work have been carried on here since August, 1918, in connection with destroyers and yachts. The station at La Trinite is nearing completion and that at La Pallice is progressing rapidly. The utility of the station at La Trinite seems to be somewhat in doubt, as the original purposes for its establishment have undergone some change due to alterations in the methods of handling convoys, coastal as well as on and off shore.
