R.R.S. 'DISCOVERY IF 97 



for photographing charts and illustrations. On the port side of the forward bulkhead is 

 a sink with taps for hot and cold fresh water and salt water, and above it a large washing 

 tank for X-ray negatives and large plates. In the starboard side of the forward bulkhead 

 is the door to the dark room. Immediately abaft the dark-room door on the starboard 

 side stands a tier of large chart drawers with a flush top, part of which is constructed to 

 form a chart tracing table consisting of a heavy plate of glass which can be illuminated 

 by a movable lamp from below. This space was formerly occupied by a half-plate 

 camera, fixed vertically over a platform on which small organisms could be photo- 

 graphed with the aid of powerful spotlights. 



Farther aft on the starboard side there are two high tiers of drawers used for storing 

 spare stationery and apparatus. In the after port corner is a lift for passing stores to the 

 biological laboratory above. It opens at the after end of the dividing bulkhead between 

 the biological and hydrological laboratories. 



Two book-shelves along the port side and one along part of the starboard side of the 

 room are used for carrying a part of the scientific library. 



The photographic equipment of the ship includes a Sanderson half-plate camera with 

 which records of the work on board, of whaling activities, of natural life and of the 

 places visited are made. 



SCIENTIFIC INSTRUMENT STORE AND WORKSHOP 



The small room between the carpenter's shop and the petty officers' bathroom, in the 

 block of houses outside the port alleyway, is used as a scientific instrument store and as 

 a workshop for the repair and overhaul of scientific gear. A bench runs along its out- 

 board side with a port and a bracket light above. A small vice is attached to the bench 

 and there are two tiers of drawers and open stowage space below the bench. All the 

 available wall space is occupied with racks holding Nansen-Pettersen and Ekman 

 water bottles, metre recording blocks, echo-sounding machine spares, current meters, 

 release gears, Baillie sounding rods, harpoons and harpoon guns, sporting rifles and 

 ammunition. On the deck against the bulkheads are racks for depth gauges and stream- 

 lined leads. 



Of the two or three scientific assistants, each of whom ranks as a petty officer in the 

 ship's complement, one is a man having electrical and general technical knowledge. His 

 first duty is the care and operation of the echo-sounding machines (p. 102), but he has 

 in addition the general care of scientific gear used on deck, with the exception of nets. 

 The scientific storeroom is at the same time his workshop. 



NET STORE 



The long narrow room, which is the after compartment in the starboard block of 

 deck houses, is used as a net store and workroom. Its position on the starboard side 

 corresponds with that of the rough laboratory on the port side, and it is in a similar way 

 near to the points from which nets are worked. The single door opens to the after deck. 

 There are deep racks against the forward bulkhead for the accommodation of spare
