XXXVI REPORT OF COMMISSIONER OP FISH AND FISHERIES. 



Od tlie return of car No. 3 from its last trip to the Pacific Coast it 

 was sent to Tampa, Fla., to remain during the sessions of the Fisheries 

 Congress, from January 19 to 26, for the purpose of illustrating the 

 methods employed in hatching eggs and distributing fishes. 



In July car No. 1 was placed in the shops of Jackson & Sharp, and 

 in August car No, 3 in the shops of Harlan & Hollingsworth, Wilming- 

 ton, Del., and were rebuilt at an expense of about $11,000. They were 

 remodeled on practically the same plan, except that the center doors 

 of car No. 1 do not extend to the floor, as is the case in car No. 3. 



The dimensions of car No. 3 as rebuilt are as follows : Length of body, 

 60 feet; total length from end of platform to end of platform, 67 feet 10 

 inches; width, 9i feet; height from top of rail to top of roof, 13 feet 8 

 inches. The frame of the car is so braced as to permit of the two large 

 doors in the center extending from floor to roof, as shown in plate IV. 

 This feature very materially simplifies loading and unloading. The 

 interior of the car is finished in ash, and in one end is an office, an 

 ice-box of 1^ tons capacity, and a pressure tank holding 500 gallons 

 of water; at the other end are the boiler room and kitchen. The boiler 

 room is equipped with a 5-horsepower boiler, circulating water pump, 

 and air and feed pump. The tanks and cans used in transporting fish 

 are carried in two compartments running along the sides of the car 

 between the office and boiler room. They are 30 feet long, 3 feet wide, 

 and 25 inches deep. Under the car, between the trucks, is a reservoir 

 tank holding 000 gallons of water, and from which water is pumped into 

 the pressure tank near the office; it then passes from this tank to the 

 fish cans and tanks, and then back to tlie reservoir. In the middle of 

 the car, over the compartments referred to, are four berths and several 

 lockers for the use of the crew. Tbe office also contains two berths, a 

 writing desk, and a typewriter. These cars are fully equipped with all 

 modern improvements in the way of brakes, couplers, signal whistles, 

 etc, and have Pullman trucks and 33-inch Allen paper wheels. With 

 the large water capacity provided, they are capable of carrying much 

 greater loads of fish than ever before. 



EXPOSITIONS. 



The Tennessee Centennial Exposition, in progress at Nashville at 

 the close of the fiscal year, was terminated October 31, and all mate- 

 rial except the aquaria was returned to Washington. During July and 

 August much difficulty was experienced in keeping up the.display of 

 fishes in the aquarium on account of the intense heat. During June 

 the temperature of the salt water rose rapidly, and when it reached 

 78° it became necessary to adopt artificial means to save the fish, 

 notwithstanding the fact that the specimens exhibited were all collected 

 in southern waters, at Morehead City, N. C, and Pensacola, Fla. This 

 was accomiflished by passing all the water used through 300 feet of 

 pipe coil, packed in crushed ice and salt. This method proved very 

 expensive, as it required over H tons of ice per day to reduce the 

 temperature below the danger i)oint, that is, 70°.
