port side and a laboratory room on the starboard side which is used for 

 the chemical analysis of sea water. Above the extreme after end of the 

 central passage is an emergency escape hatch. Finally, there is the laz- 

 arette for the quadrant and other steering equipment to be used in case of 

 a failure of the shafts between the pilothouse and the engine room. 



The hold or B deck. From the peak of the ship aft on the hold or B 

 deck level are located the forward trim tank, the refrigerators, with two 

 cold boxes on the port side and three on the starboard, and the dry stores. 

 Between the dry stores and the engine room are located the deep oil tanks, 

 port and starboard. Each is divided into three compartments to prevent 

 slopping with the roll and pitch of the ship. With one or two exceptions, 

 there are no shell tanks. Aft the watertight bulkhead is the main deck of 

 the engine room, previously described in connection with lower deck A. 

 Aft the engine room are the shaft alleys, each allowing inspection of any 

 part of the shaft, and between them are two double-bottom fresh-water 

 tanks of 4,000-gallon capacity each. A passageway connects the shaft 

 alleys aft the water tanks. It is followed by a watertight bulkhead, an- 

 other fresh-water tank, and the after trim tank. Outside the shafts are 

 four fuel oil wing tanks, two on either side. Below the cold stores is a 

 fresh-water tank, below dry stores two double-bottom oil tanks. Under 

 the engine room deck are an oil cooler and six double-bottom oil tanks, 

 and below these are the bilges. While the ship is running, fuel oil is often 

 pumped from tank to tank to keep her on an even keel. 



General. All decks are of steel plate. On the flying bridge, the boat 

 deck, and all boat deckhouse coverings, over the steel there is a joiner deck 

 of Douglas fir, separated by a space through which there is air circulation, 

 and over this, a canvas covering. In the boat deckhouses, the canvas is 

 replaced by battleship linoleum. On the exposed portions of the upper 

 deck, and in the principal compartments of the upper and lower decks, 

 mastic replaces the joiner deck, and battleship linoleum is used for cover- 

 ing. On the fo'c's'le deck and the various workrooms, paint is used in 

 place of linoleum. The galley, pantry, and toilet and washrooms are tiled. 

 The staterooms are insulated at shipside with two inches of cork. 



The bilge, ballast, and fire systems are handled separately. There are 

 two fresh-water systems, one for drinking and cooking, and one for lava- 

 tory, shower, and laundry purposes. The capacity of each system is 9,000 

 gallons. Fresh water is circulated by automatic pumps and pressure tank. 

 The water is heated electrically (all heat is electrically produced), and 

 for this heating the ship is divided into three zones, each with a separate
