Hold. — There are five iron bulkheads, all of which, with one exception, 

 are water-tight. In the hold, abaft the collision bulkhead, are two 

 ice-houses, about 10 feet square. Forward and aft of these are several 

 store-rooms, including two for natural history •purposes. Next aft is 

 the steerage, having a length of 15 feet. Under the steerage and store- 

 rooms is the forehold, 32£ feet long, and containing the water tanks, 

 having a capacity of 800 gallons. The boilers, coal bunkers, fire-room, 

 and engines are located between bulkheads Nos. 3 and 4, abaft of which 

 is the lower cabin, 26 feet loDg, with seven open bunks on each side, 

 and including the dispensary, a linen room, pantry, and store-room. 

 Still further aft, in the stern of the ship, is a cabin store-room, entered 

 through a scuttle in the main deck. 



Main deck. — The forecastle extends 31 feet aft from the stem, and is 

 succeeded by the main or hatching deck, which is 47 feet long. The 

 latter has on each side a gangway port abreast of the foremast, 6 

 feet wide and extending from deck to deck, and four large swinging 

 ports. The boiler hatch occupies the after part of this deck, and is raised 

 about 9 inches above it. On the hatch are placed the donkey-pump 

 and distributing tanks for the hatching apparatus, which is arranged 

 around it. When engaged in dredging, the hatching apparatus, except- 

 ing the pump, is entirely removed from this deck, and it becomes the 

 working quarters of the naturalists. The beam trawls and dredges, 

 which are manipulated from the upper deck, are passed in at the gang- 

 way port on the starboard side, their contents emptied into sieves and 

 washed, and then transferred to swinging tables, where they are sorted, 

 examined, and studied. The arrangements for this class of work are very 

 convenient, and the working space ample. With all the ports open on 

 both sides, the deck receives an abundance of light. The donkey-pump 

 is used for washing the materials emptied into the sieves. 



Abaft the hatching deck come the donkey boiler room and galley, the 

 engine-room and cabin pantry, and finally the cabin, followed by the 

 small after deck in the stern, which is about 14 feet long. The cabin 

 is abaft the engine-room, is 30 feet long, and has four rooms on a side, 

 with one bunk in each. 



Aft, on the starboard side, is the Fish Commissioner's office. The
