feet, two humlred feet. The breadtli of beam 

 moul(le(l is twenty-seven feet and a half. The 

 registered net tonnage is four hundred tons, and 

 the displacement on a twelve-feel draught, a 

 thousand tons. The frame-work and hull are of 

 iron, which also enters large!}' into the construc- 

 tion of the deck-house. Forward and aft, the 

 iron sides extend to the level of the upper deck 

 to enclose the poop-cabin and top-gallant fore- 

 castle, wiiilc in the intervening si)ace they 

 form a high protecting rail to the main deck. 

 The deck-house (7-14), which is eighty-three 

 feet long, thirteen feet and a half wicle, and 

 seven feet and a quarter high, extends from 

 just forward of tlie mainmast nearly to the 

 foremast, leaving an ample passageway on 

 either side between it and the rail. The after- 

 part is built of iron, with wooden sheathing; 

 but forward of the funnel it is entirely- of wood. 



followed by the steerage (20), main laboratory 

 (21), engine and boiler compartments (24, 

 22), which extend into the hold, and the 

 ward-room (2.")). 



The forehold contains the magazine (27), 

 water-tanks, ice-house (29). and a variety of 

 storerooms. Underneath tlie laboratory is a 

 large room (32) for the stowage of natural 

 history materials : and lielow the ward-room are 

 the appropriate storerooms for the use of the 

 mess, the navigator, and paymaster. 



The poop-cabin (1-5) , on the main deck, is a 

 large, commodious room the entire width of the 

 ship, and extending thirty feet forward from 

 the stern. It contains two state-rooms, a bath- 

 room, pantry, and office, and is convenientlj' 

 furnished. The ward-room (2.5) underneath 

 is thirty-eight feet long, and has eight large 

 state-rooms, a bath-room, and pantry. It is

The forward compartment, which is raised 

 about three feet above the genei-al level of 

 the house, is the i)iIot-house (7), containing a 

 steam quartermaster to aid in steering. Fol- 

 lowing it in succession are the chai't-room 

 (8), up|)er laboi-atoiT (9), four state-rooms 

 (10), steam drum (11), galley (12), upper 

 engine-i-oom (i;5), and entrance to the ward- 

 room stairway (14). 



Below the main deck the vessel is divided 

 into six water-tight compartments by five trans- 

 verse iron bulkheads, there being also an addi- 

 tional bulkhead which is not closed. 



The berth-deck, forward of the collision 

 bulkhead, is cut up into stoi'ci'ooms (16), 

 reached by scuttles fiom the main deck. Next 

 aft is the bei-th-deck pi'oper ( 1«), which is forty 

 feet long and the wiillh of the ship, with supe- 

 rior accommodations for a large crew. It is 



well lighted l)y a broad skylight overhead in 

 addition to the usual side-ports. These quar- 

 ters ai-e entii-ely occupied hy the offlcei's of the 

 ship, the civilian scientific staff being accom- 

 modated in the four state-rooms (10) of the 

 deck-house abaft the upper laboratory. The 

 latter rooms are better iidapted for study than 

 any others on the ship ; each having a large, 

 squai-e side-window at the proper iieight for 

 woi'king with the micioscope. should the natu- 

 ralists desii'e to conduct their more delicate 

 observations in privacy. 



Of most interest to tiie student are the sci- 

 entific quaiters, which are veiy capacious, and 

 amply sutiicient for all possible needs. They 

 occupy a ccnti-al position, being thereby re- 

 moved as far as possible from the exti-emes of 

 motion caused by rolling and pitching. They 

 extend from just above the keelson to the upper
