Since the war service of the vessel started until November 11, 1918, the _Leviathan_ has never had an engineering casualty of any description, nor has the ship been delayed due to any cause in the engineering department. The Medical Department By DR. DUNLAP The Medical Department is represented by the Senior Medical Officer, Commander F. A. Asserson, M. C. U. S. N., four Junior Medical Officers with the rank of Lieutenant each, one Chief Pharmacist, one Pharmacist, two Chief Pharmacist’s Mates, and about one hundred and thirty Hospital Corpsmen. There are also eight nurses, in charge of Miss Mary M. Robinson, Chief Nurse, U. S. N. The units composing the Department are as follows: Office of the Senior Medical Officer; office of the Medical Officer of the Day; Major and Minor Operating Rooms; Laboratory; Sick Officers’ Quarters of ten beds; Medical and Surgical Wards with one hundred and thirty-two beds; Isolation Ward with forty beds; total, one hundred and eighty-two beds; Diet Kitchen; two Sick Call Stations; Dispensary; Mental Ward; Guinea pig houses. The history of this department dates from July, 1917, when the first medical officers, Drs. F. J. Carroll, and E. M. Hudson came aboard. These officers, both Lieutenants in the U. S. Naval Medical Corps, were on duty at the U. S. Naval Hospital in Brooklyn when our government assumed control of the _Leviathan_, and they were ordered to report aboard for duty. The vessel at that time being just as the Germans had left her. Drs. Carroll and Hudson at once began tentative plans for a medical department capable of handling the sick among the thousands of troops the _Leviathan_ was being rapidly fitted to carry. Plans were drawn by them converting the social hall on A-deck into wards and operating rooms. The orchestra stage at the forward end of the hall was to be cut away, lowered to the level of the deck and that space utilized as two operating rooms with a sterilizing room. Wash rooms, toilets, linen lockers, and an Isolation Ward were also provided for. Places fore and aft were chosen as sick call stations and Dispensary.
