R.R.S. DISCOVERY 11' 89 



The after end of the officers' accommodation is bounded by the stokehold bulkhead, 

 through which a steel watertight emergency door gives access to the stokehold on the 

 starboard side. In the middle line aft is a large linen locker, and the double staircase, 

 leading up to the laboratory lobby, abuts on the fore side of this linen locker. On the 

 port side of the staircase is the cabin of the scientific officer in charge (Plate VII, fig. 4), 

 which is larger than the other cabins and is panelled in oak. 



The centre part of the officers' accommodation is partitioned oflF by wooden bulk- 

 heads to form a photographic room, with the door at the after end and a dark room 

 leading from it. 



Forward of the photographic room is the fore hold, which extends from the main oil 

 tanks just abaft the coaming of the fore hatch to the collision bulkhead and down to the 

 double-bottom tank tops. The square of the hatch and the wings in the way of it are 

 clear, and the fore end is divided by wooden battens into tiers of lockers which are set 

 apart for special stores such as medical, canteen, and clothing, while the main clear 

 section is used for foodstuffs. 



The petty officers' mess deck extends from the after engine-room bulkhead to the 

 forward bulkhead of the after hold 'tween deck and, like the officers' accommodation, 

 is divided into cabins along each side. Each of these cabins is arranged to accommodate 

 two men, and the centre space of the flat is occupied by a long mess table. A pantry, 

 with hot press and calorifier, occupies the port forward coiner of the flat. Inboard of 

 the pantry is a cold store, consisting of two separate freezing rooms and a small air-lock 

 or handling chamber, in which boxes for making ice are fitted. Freezing is effected by 

 an ammonia refrigerator arranged in a compartment built on to the after end of the 

 upper deck as previously mentioned. 



The after hold extends under the petty officers' mess deck, forward to the engine- 

 room bulkhead and aft to the line of the poop front bulkhead. This hold is used only for 

 scientific stores and is fitted with racks and bins for the storage of nets, bottle boxes and 

 all kinds of scientific gear. 



Throughout the ship all living quarters and enclosed spaces in which men may be 

 required to remain for some considerable time are insulated on all surfaces exposed to 

 sea or air. Thus in the officers' and petty officers' accommodation the outside walls of 

 the cabins and the deckheads are insulated, and in the case of the deck houses, all out- 

 side bulkheads as well. This insulation, which has proved very effective, consists of 

 fireproof cork slabs between the exposed surfaces of the bulkheads or decks and the inside 

 panelling. 



ENGINE ROOM 



The machinery installation consists of a set of single-screw triple-expansion surface 

 condensing machinery specially designed and constructed for service in the Antarctic 

 and to contend with the low temperatures prevailing in these latitudes. 



Particular attention has been paid to bearing surfaces, which are specially large to 

 ensure the machinery working for long periods without adjustment.
