Fuel for the navy has been handled by means of allotments placed with the principal operators in coal-producing States, the prices being fixed by the Fuel Administrator. The navy's stocks of fuel have been maintained to capacity, and shipments have been made to the fleet within the time required in all cases. Fuel oil has been obtained in similar manner at the prices fixed by the Federal Trade Commission. The Medical Department of the navy passed quietly from a peace to a war footing on April 6, 1917, and has since continued to give adequate and satisfactory service. With the completion of a hospital ship now building, the navy will have four hospital ships as against one when war began. Prior to the war there were about 375 medical officers on duty. There are to-day 1,675 medical officers in active service, and 200 more on reserve. Where 30 dental surgeons were formerly employed there are now 245. The number of female nurses has increased from 160 to 880. The President at the outbreak of war directed the Navy Department to take over such radio-stations as might be required for naval communications, all others being closed. Fifty-three commercial radio-stations were thus taken into the Naval Communication Service. Because of duplications, twenty-eight of these stations were closed. Thousands of small amateur radio-stations were closed. At present no radio communication is permitted on United States territory (not including Alaska), except through stations operated by the Navy Communication Department or by the War Department, With the need of operators apparent, a school for preliminary training in radio-telegraphy was established in each naval district, and when the need for a central final training-school developed, Harvard University offered the use of buildings, laboratories, and dormitories for this purpose. The offer was accepted, and now the naval-radio school at Harvard is one of the largest educational institutions in the country. There is another final training-school at Mare Island, Cal. The navy supplies the operators for the rapidly increasing number of war vessels, and has undertaken to supply radio operators for all merchant vessels in transatlantic service. At Harvard and Mare Island the radio students are put through four months' courses, which embraces not only radio-telegraphy and allied subjects, but military training. Some 500,000 men have been undergoing courses at these two schools alone. When war occurred the Coast Guard was transferred from the Treasury Department to the Navy Department, and the personnel now consists of 227 officers and 4,683 warrant officers and enlisted men.
