240 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



thus causing it to roll from side to side in such a manner as to make it 

 unsafe. It was also found tbat while the refrigerator compartment 

 carried the fish safely, the health of the messengers was injuriously 

 affected owing to the sudden changes of temperature experienced in 

 going to and from the compartment. Accordingly, another car was 

 built in which these defects were remedied, and the original car was 

 altered to conform to the improved plan. 



The Commission now has four transportation cars in use. While 

 they differ somewhat in construction and arrangement, three of them 

 are essentially alike; the fourth is simply a baggage car with living 

 quarters and circulating apparatus. The car known as No. 2 is 

 regarded as the best type. Its body is 52 feet 7 inches long; from 

 buffer to buffer, 59 feet 9 inches; width, 10 feet; height, from top of 

 rail to top of car, 14 feet 3 inches. It is equipped with 6-wheel Pull- 

 man trucks, i)aper wheels, combination couplers, etc., so that it can be 

 hauled on passenger trains. Underneath, between the trucks, are boxes 

 for carrying provisions, tools, extra couplers, and a water-tank. Inside 

 the car is finished in white ash, and due arrangements are made for the 

 comfort and convenience of the crew. In one end is an office for the use 

 of the captain, containing a sleeping-berth, desk, and toilet facilities; 

 at the other end is the kitchen, with lockers for dishes, also the air- 

 IHimi), steam-jmrnp, and a 5-horsepower boiler for furnishing necessary 

 power. 



The fish are carried in tanks or cans arranged in two refrigerator 

 compartments on each side of the passageway. Over these compart- 

 ments are two upper berths on each side for the accommodation of the 

 crew, whose meals are served on a large table, placed when in use in 

 the passageway in the center of the car. Chairs without legs are pro- 

 vided, so that they can be placed on top of the refrigerators. 



The refrigerator-chambers are 26 inches high and 31 inches wide, and 

 provided with lids; the partitions are filled with cork, which is used on 

 account of its nonconducting ])roperties. At one end of the chambers 

 is an ice-box, which holds about three-fourths of a ton of ice. 



The transportation-tanks used in carrying yearling and adult fishes 

 are made of heavy galvanized iron, and are 27 inches long, 27 inches 

 wide, and 24 inches deep, holding 52 gallons each. They are heavily 

 coated with asphalt before being used. 



For the transportation of fry ordinary 10-gallon iron cans, tinned, 

 are used. These cans are 24 inches high, 12 inches in diameter on the 

 outside, with sloping shoulders and cover, and two handles on the 

 sides for convenience in moving. The water is introduced by means of 

 a rubber hose connected with the pressure tank, or simply with a dipper 

 or bucket. 



The supply of water is carried in an iron pressure-tank of 500-gallon 

 capacity, Avhich is located in the body of the car next to the office. The 

 water is circulated by means of a steam-pump through galvanized-iron
