R.R.S. 'DISCOVERY IF 87 



equipped with a short-wave transmitter and a combination receiving set with which 

 wireless communication with England can generally be maintained: blind areas are 

 occasionally found in the Southern Ocean in which both the despatch and receipt of 

 long distance signals prove impracticable. A direction finder is fitted by which the ship 

 can obtain her own position in relation to land stations and the position of other vessels 

 in relation to herself. 



The sick bay (Plate VII, fig. 3) consists of two compartments, a dressing room and the 

 sick bay proper; these are separated from the wireless room by a steel bulkhead, and 

 from each other by a fore and aft wooden bulkhead with a communicating door. The 

 dressing room on the starboard side is the larger compartment and contains a settee, a 

 sink, and a large medicine chest, together with a desk and a cupboard for the accommo- 

 dation of medical stores. A Phillips X-ray outfit and a dental machine are provided. 

 The sick bay itself contains two swing cots, one above the other, and a wash basin. The 

 lighting of this house is by square wooden-framed drop windows, and both compart- 

 ments have doors opening on to the boat deck. A narrow alleyway bounded by an open 

 rail separates the after end of the sick bay from the break of the boat deck. 



NAVIGATING AND FLYING BRIDGES (Plate IV) 



The navigating bridge is situated immediately above the wardroom house, the deck 

 extending to the ship's side and flush with the break of the boat deck forward. Teak 

 ladders on either side, placed just abaft the wardroom doors, lead from the boat deck. 

 The deck house on this bridge is of teak and contains the chart room, an echo-sounding 

 compartment, the captain's cabin and a small survey office. Forward of this house and 

 abutting on it is the wheel house or wheel shelter, eight feet wide and fitted with square 

 drop windows on each side and in front. The wheel house is entered by sliding doors on 

 either side and contains the wheel, Telemotor steering gear, steering compass, flag 

 lockers, speaking tubes and a telephone to the wireless room. Two Kent's clear-view 

 screens are fitted in the forward wheel-house windows to enable the officer of the watch 

 to keep a good look-out in snowstorms and heavy weather, and at the angles of the bridge 

 two lo-in. Admiralty searchlights are mounted. The bridge, at its fore end and lor 

 10 ft. along each side, is protected by a teak panelled rail and the after end by an open 

 rail covered with painted canvas. In the forward wings of the bridge are engine-room 

 telegraphs with extensions to the flying bridge. On the starboard side, just beneath the 

 ladder leading to the flying bridge, an electrically driven Kelvin sounding machine is 

 fitted, and an electrically operated revolution indicator is placed on the port side. Flag 

 lockers and a sanitary tank are placed abaft the house. 



The chart room and echo-sounding compartment occupy the whole width of the 

 forward section of the house. The chart room is 7 ft. wide ; it has an insulated teak door 

 on the starboard side, a door communicating with the echo-sounding compartment on 

 the port side and two windows opening into the wheel house. It contains a large chart 

 table with drawers below, a chronometer box, lockers for instruments, the receivmg 

 portion of the direction-finding apparatus and the recording dial of the Chernikeef log.
