 and 800 gallons of potable water per diem. 



OUTFIT. 



The contract for building the vessel covered only hull and machin- 

 ery, the outfit being provided from a special appropriation. 



Anchors, chains, hawsers, &c., were loaned by the Bureau of Equip- 

 ment and Eecruiting, Navy Department. 



Boats — gig, cutter, and dingy— by the Bifreau of Construction and 

 Repair. 



Compasses, flags, nautical instruments, books, and chronometer by the 

 Bureau of Navigation. 



Small-arms and ammunition l)y Bureau of Ordnance. 



Charts and Atlantic Coast Pilot were furnished by the United States 

 Coast and Geodetic Survey. 



The various articles of outfit were procured by open purchase at reas- 

 onable prices and have given general satisfaction. 



FISH-HATCHING MACHINERY. 



The fish hatching machinery was constructed by the Pusey & Jones 

 Company under special contract, and consists of a Woodward steam- 

 pump with water cylinder, 5 inches diameter and 13 inch stroke, capable 

 of supplying 10,000 gallons of water per hour. 



Two iron distributing tanks with a capacity of 500 gallons each are 

 I)laced forward of the jiump on the boiler hatch and raised 3 feet 4 

 inches above the deck. (Plate II.) 



There is a water connection and proper valves between the pump and 

 tanks, with overflow and drain pipes connecting with the general deliv- 

 ery for hatching machinery. There is also an arrangement of valves 

 by which the water can be pumped back into the tanks and used as 

 often as desired instead of discharging it overboard. 



HATCHING CONES. 



The number of hatching cones on board at present is thirty-six, cap- 

 able of hatching 7,200,000 shad at a time, or 200,000 each when charged 

 to their full capacity. 



The number of cones can be increased about one-third in case of ne- 

 cessity. The material of which they are made is copper, tinned inside, 

 and the mountings are of brass. Their arrangement on the port side of 

 deck will be seen by reference to the Plate. They are in sets of 4 and 6 

 to each frame and are hung on gimbals which permit a free motion in 

 every direction, maintaining a vertical position even when the vessel is 

 in violent motion. 



In artificial fish hatching it is necessary to maintain a constant and
