The top gallant forecastle is 44 feet in length and 6 feet 3 inches in 

 height, from deck to deck. The anchors, which are stowed on this deck, 

 are handled by a single fish-davit, common to both, and a steam capstan. 

 On the port-side, near the after end, is the Sigsbee deep-sea sounding 

 machine. 



Under the top-gallant forecastle are water-closets for officers and 

 crew, men's bath-room, lamp-room, paint-locker, steam windlass, &c. 

 There are two scuttles under this deck, one giving access to the store- 

 rooms, magazine, &c, forward of the collision bulkhead, the other, to 

 the berth deck, for use in bad weather. The forehatch also gives access 

 to the berth-deck, which extends 40 feet fore and aft, is 7 feet 10 inches 

 in height between decks, and comfortably fitted for the accommodation 

 of the crew. Opening from the after end of the berth-deck is the steer- 

 age, provided with four double-berth state-rooms and a mess-room. 



Abaft the steerage, but separated from it by an iron bulkhead, is the 

 il lower" laboratory immediately below the "upper" laboratory, through 

 which only can it be entered'. This room extends quite across the ship, 

 is 20 feet long, 7 feet 10 inches in height between decks, and is lighted 

 in daytime by six 8-inch side lights, two 12-inch deck lights, and the 

 hatch at the head of the stairway. Ample storage cases and lockers 

 are provided for alcohol, jars, and specimens; long work-tables are 

 placed on each side; in one corner is a large lead-lined sink with run- 

 ning water; in another, a photographic dark-room; and, across the 

 after end, the chemical laboratory. 



Below this room is the store-room, a closed iron box capable of being 

 isolated from the rest of the ship and filled with steam at short notice, 

 in case of fire. Here are stowed alcohol, specimens, nets, &c, for which 

 lockers have been provided. 



The vessel is propelled by twin screws, 9 feet in diameter and 14 feel 

 10 inches mean pitch. They are driven by two compound engines with 

 two cylinders each, the high-pressure cylinders 18 inches and the low- 

 pressure 34 inches diameter of bore, and 30 inches stroke of piston.
