88 DISCOVERY REPORTS 



The echo-sounding compartment contains three echo-sounding machines and recorders 

 of the Admiralty pattern, and the recording dial of the Munro anemometer. Further 

 reference to the sounding machines is made below on p. 102. 



On the starboard side, abaft the chart house, and communicating with it by a sliding 

 door, is the captain's cabin, which is panelled in light oak, and on the port side is a small 

 compartment used as a survey office. 



The flying bridge extends above the house on the navigating bridge, with wings 

 running out to the ship's side at the fore end. It is reached by a teak ladder on either 

 side. It is protected by a teak-capped open brass rail covered with a painted canvas 

 weather cloth and is generally used for coastal navigation and surveys, and sometimes 

 for ice work, as a better view may be had from it over the forecastle head. 



In the midship line, near the forward part of the flying bridge, is the standard compass, 

 with a Kelvin lo-in. dry card. Abaft the compass is the aerial of the direction finder, 

 the receiver for which is in the chart house below. Next aft is a stand for a metre range 

 finder, and an ordinary ship's semaphore surmounted by a Morse flash lamp. On the 

 starboard side, in the after corner of the bridge, is a 9-ft. range finder, which is used in 

 running surveys. On the port side is the vane of the Munro anemometer, the dial of 

 which is in the echo-sounding cabinet. A portable chart table is carried close to the 

 forward rail on the same side. 



MAIN DECK (Plate V) 



Between the stem and the collision bulkhead, a fore-peak storeroom is provided for- 

 ward of the chain locker ; access to both these compartments is by a hatchway in the 

 upper deck. 



The crew's quarters, entered by a companion from the forecastle space, occupy the 

 main deck between the collision bulkhead and the officers' accommodation. The mess 

 deck is divided in the middle line and the half length of the flat by wooden partitions, 

 the stokers occupying the smaller space which comprises the port after portion of the 

 flat. In the seamen's mess deck wooden bunk accommodation is provided for sixteen 

 men, and the usual lockers and tables are fitted. The stokers' mess has accommodation 

 for six men. 



The officers' accommodation (Plate VII, fig. 2) connects with the mess deck by means 

 of a watertight door in the dividing steel bulkhead and contains fourteen cabins for 

 officers and scientific staff, arranged along each side of the ship. At the forward end are 

 two bathrooms, one on each side, fitted with calorifiers and wash-basins. Since the main 

 deck is below load water-line the waste water is run into a sanitary tank and pumped 

 over the side. The cabins are all of the single berth type and each is provided with a 

 steam heater and an electric fan. There are no portlights in the main deck, but light is 

 admitted into each cabin by stout double glass decklights. Ventilation is provided by 

 brass screw mushroom vents to each cabin, but in heavy weather it was found difficult 

 to keep these watertight, and in high latitudes they were always unshipped while at sea 

 and the brass deadlights, provided for the purpose, screwed up in their places.
