[93] WOEK OF FISH COMMISSION STEAMER ALBATROSS. 209 



uot ; in cold and wet weather they assist in keeping the deck dry and 

 warm, but when the ship is at work in tropical climates they increase 

 the temperature. The deck is supplied with two steam-heaters, and its 

 average temperature is about 74° F. On the after part of this deck is 

 the engine for reeling in the wire cable used in dredging operations. 



The steerage IS on the after part of the berth-deck; the apothecary, 

 yeomen, and machinists live here. The steerage consists of a country 

 12^\ feet long and 7^ feet between decks, and four state-rooms, two 

 on a side ; each state-room contains two bunks, one above the other ; 

 the bunks are 6 feet long. The cubic capacity of the steerage, country, 

 and state-rooms is 2,184 feet. Each state-room has a circular air- port, 9 

 inches in diameter in the clear, and a register for artificial ventilation. 

 The steam pipes for the anchor, dredging, and capstan engines pass 

 through the steerage, and formerly made it very hot. This has been, 

 to a very great degree, remedied by introducing through the main deck 

 a 12-inch ventilator. The average temperature of these quarters prior 

 to this, when steam was being used on forward engines, was 90° F., 

 and the average now, under same conditions, is 80° F. 



ThQ Jire-room is a very cool one, the average temperature during the 

 year being only 90<^ F. The engine-room is cool, compared to many 

 naval vessels; the hottest part is about the starting gear, which is just 

 beneath the galley. The average temperature here for the year was 

 llOo F. 



The ward-room is 38 feet long and 7-^ feet between decks. It differs 

 in i^lau from the usual ward-room in that forward of the state-rooms is 

 a clear space, the entire width of the shii) and 12^ feet deep. Abaft 

 this space and on starboard side are three state-rooms and bath-room. 



All bunks in this ship, except those in steerage, are 6-^\ feet long. 

 On port side are four state-rooms. Forward of ward-room, on starboard 

 side, is the chief engineer's room, and on port side is the pantry, with 

 a large store-room beneath. Under ward-room country are the pay- 

 master's and navigator's store-rooms. Over forward part of ward-room 

 is a hatch 7 by 5 feet. In the country are six registers for artificial 

 ventilation, three on a side, and four circular air-ports, 9 inches in 

 diameter, two on each side. Every state-room contains a register for 

 artificial ventilation and one of the circular 9-inch air-ports. The cubic 

 space of the country, state-rooms, and pantry is 4,300 feet. The aver- 

 age size of the state-rooms is 360 cubic feet. 



Seating. — -All parts of the ship are fitted with radiators supplied with 

 steam from the main boilers. 



Ventilation. — Ventilation is effected in part by the natural entrance 

 of air through air-ports, doors, windows, and hatches, and largely by 

 artificial means. The artificial ventilation is effected on the aspiration 

 system by means of a No. 6 Sturtevant exhaust fan, propelled by a Wise 

 steam motor, which is a kind of rotary machine, patented and manu- 

 factured by Thomas Wise, of South Framiugham, Mass. The motor is
