R.S.S. 'WILLIAM SCORESBY' 175 



illustrated in Plates XIV-XVI. The equipment for scientific work is dealt with 

 separately on p. 178. 



At the forward end of the Upper Deck there is a short forecastle head, providing a 

 platform, protected at the bow by a stout wooden bulwark, from which whale-marking 

 experiments can be undertaken. At the after end of the forecastle a 16 in. searchlight 

 projector is fitted on an elevated pedestal. 



Immediately abaft the forecastle head is a steam and hand capstan, the base of the 

 capstan head being fitted with a gypsey for dealing with the vessel's cables. The main- 

 mast is of extra heavy steel construction, suitable for whaling if required, and is 

 fitted near the centre of the fore deck. Immediately abaft the mast is a combined steel 

 companion way and skylight, giving entrance and lighting to crew space, chart room 

 and officers' quarters below deck. A large steam winch of special design is fitted at 

 the after end of the fore deck. On the starboard side of the fore well deck, abreast of 

 the main-mast, are the Lucas sounding machine and the hydrological reel, both 

 driven by the same compound surface condensing engine. This machine and the 

 winch are separately described on pp. 178, 179. 



Immediately forward of the boiler casing the laboratory is constructed. It is built 

 of teak, fitted with unusually large port lights, the construction being similar to that 

 adopted for the deck houses in the ' Discovery'. Above the laboratory is the navigating 

 bridge, with a teak wheelhouse to enclose the helmsman. The forward part of the bridge 

 is extended out to the sides of the ship to enable the officer of the watch to see 

 fore and aft on either side when coming alongside, and this extension is supported on 

 heavy teak beams. The wheelhouse contains an echo-sounding installation for depths 

 not exceeding 130 fathoms, in addition to a Kelvin liquid card compass and the 

 engine-room telegraph. The roof of the wheelhouse is surmounted by a small bridge, 

 upon which the standard compass is fitted, enclosed by brass rails and stanchions. 

 Portable awnings are arranged above the navigating bridge and standard compass 

 position and a Morse signalling lamp is fitted forward of the compass. 



The engine and boiler casings, which are of steel, extend over practically the whole 

 length of the engine and boiler space. On top of the casing between the funnel and 

 the engine-room skylight a steel house is constructed for the wireless installation. The 

 wireless installation is similar to that fitted in the ' Discovery', and consists of a Marconi 

 quench-gap installation and a continuous wave set, both of i| kw. capacity. In order 

 to give quieter working conditions the alternator was fitted in the engine room, instead 

 of in the wireless house as is customary. 



The engine-room skylight is fitted immediately abaft the wireless house on the top 

 of the engine casing, and is of steel with brass frames for the glass. This type of skylight 

 was specially selected as suitable for both tropical and Antarctic conditions. At the 

 after end of the engine casing on the main-deck level, room is provided for the steam 

 steering gear, which is thus immediately under the eye of the engineer on watch. The 

 galley is arranged at the extreme aft end of the engine casing and is divided from the
