on which are located the pilot house, captain's quarters, and labora- 

 tory. She has five iron bulkheads, all of which, with one exception, 

 are water-tight. 



Dimensions of vessel. — Length over all, 156 feet 6 inches; from 

 rabbet to rabbet, on the 7-foot water line, 146 feet 6 inches; beam 

 molded, 27 feet; depth of hold, 10 feet 9 inches; sheer forward, 

 4 feet 4 inches; sheer aft, 1 foot 9 inches; mean draft, 6 feet 5^ 

 inches, ^cale of model, one-half inch' equals 1 foot. 



In the fore hold under the steerage and storerooms are the water 

 tanks, having a capacity of 800 gallons. The boiler, coal bunkers, 

 firerooms, and engines are located between bulkheads Nos. 3 and 4, 

 abaft of which is the lower cabin, 26 feet long, with seven open 

 bunks on each side, and including the dispensary, linen room, pantry, 

 and storeroom. 



On the 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, 

 G feet wide and extending from deck to deck, and four large swing- 

 ing 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 ar- 

 ranged around it. When engaged in dredging, the hatching ap- 

 paratus, excepting 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 gangway port on the starboard side, their con- 

 tents emptied into sieves and washed, and then transferred to swing- 

 ing tables, where they are sorted, examined, and studied. The ar- 

 rangements for this class of work are very convenient, and the work- 

 ing space ample. With all the ports open on both sides, the deck 

 receives an abundance of light. The donkey pump is used for wash- 

 ing the materials emptied into the seives. 



Abaft the hatching deck comes 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 

 lower cabin companion way is amidships, and a bathroom and 

 closet on the port side. 



On the hurricane deck, forward of the foremast, are the hoisting 

 and reeling engine and dredging boom, the heel of which is at- 

 tached to the mast. There are four small boats, one of which is a 

 steam cutter, of the Herreshoff pattern, with a coaling capacity for
