100 U, S. BUREAU OF FISHERIES. 



The P'earncjw tiiUisporUitlcii piuis have been very successfully 

 used during the year and the car is now fully equipped with them. 

 A trip was made from Manchester, Iowa, to Madison, Wis., just 

 before the close of the fiscal year, and 200 of these pails were very 

 successfully transported on one trip. It is found that by using 

 these pails instead of the standard 10-gallon cans the carrying 

 capacity of the car can be increased over 50 per cent, with no in- 

 crease in weight. 



During the fiscal year 173,825 fingerling pond fishes, 614,200 

 fingerling brook trout, and 1,267,400 fingerling rainbow trout were 

 distributed by the car in 23 trips, 18,685 miles being traveled. 



CAR NO. 8. 



[E. K. BuRNHAM, Captain.] 



At the beginning of the fiscal year fisheries car No. 8 was en- 

 gaged in the distribution of brook and rainbow trouts from the 

 Duluth (Minn.) hatchery; the season closed with the completion 

 of the salmon and trout distribution from the Craig Brook (Me.) 

 hatchery. 



While the car was undergoing general repairs at the Washington 

 Navy Yard during the winter its interior was sufficiently re- 

 arranged to permit of the installation of a small dining room 

 capable of accommodating four persons at the table. The dining 

 room has eliminated the annoyances attendant upon the former 

 practice of setting up a table for each meal at the center of the car, 

 thus blocking the aisle. 



By the adaptation of the fish compartment on one side of the car 

 for carrying 100 aluminum fish pails, the capacity of the car has 

 been increased from 140 cans to 170 cans of fish. At the close of 

 the fiscal year the fish compartment on the other side of the car 

 was changed by the car crew to make the total capacity of the car 

 216 aluminum fish pails. Nearly all minor repairs and many of 

 the changes and improvements in the car are made by the regular 

 car crew while distribution work is not in progress. 



The most important improvement made to the car during the 

 year was the installation of an electrically driven air pump. This 

 pump furnishes 5 cubic feet of free air per minute and is operated 

 by a one-half horsepower electric motor, the electricity being ob- 

 tained from the storage batteries of the car's electric lighting 

 system. An important saving is effected by using this electricity 

 for pumping air for the fish, as during the last fiscal year the car 

 used approximately 8 tons of anthracite coal to generate steam for 

 pumping air. 



During the fiscal vear 1923 the car was engaged in the distribu- 

 tion of fish from nine of the Federal hatcheries. Fourteen species 

 of food fishes were distributed to suitable waters in 19 States, the 

 farthest west being Utah. During the year the car handled over 

 1.500,000 fingerling and yearling fish. During the course of the 

 year the car traveled on 19 different railroads, the total miles 

 traveled being 18,823. Nineteen and one-half tons of ice were used 

 during the year for maintaining a suitable water temperature for 

 the fish.
