FISH FOR THE FORESTS 



TO.T 



Trout for Restocking Streams. 



the trout in these cans were placed in streams in the black hills national torest. as lonc. as the cans 

 are in a moving vehicle the natur.\l movement of the water is sufncient to aerate it. 



Almost in a moment the train has 

 come, the fish have been swiftly trans- 

 ferred from the fish car to the waiting 

 vehicles, the Ranger has signed the re- 

 ceipts on the run and the train is gone. 

 From this stage until the fish are final- 

 ly deposited in the waters for which 

 they are destined the work is exacting 

 and haste and unerring judgment are 

 essentials of success. 



Compared to the bulk of water 

 and number of fish contained the air 

 surface of the ordinary receptacle 

 is altogether inadequate and the water 

 must be aerated. So long as the 

 cans are in a moving vehicle the nat- 

 ural movement of the water is suffi- 

 cient, but if moNcment is suspended 

 the water must l)e dii)ped u]) and al- 



lowed to drain back at frequent inter- 

 vals. Sometimes the transportation of 

 fish across low valleys during the heat 

 of the day increases the temperature of 

 (he water to such an extent that unless 

 the cans are iced many of the fish will 

 perish. If the fish are held in the re- 

 ceptacles for any length of time the 

 water must be replenished and care 

 must be taken to see that the water is 

 suited to the fish and does not contain 

 alkali or other injurious ingredients. 

 There is imperative need to transport 

 I he fish to the |>oint of dei:)osit with- 

 nut delay and throughout its various 

 stages this part of the work is marked 

 by feverish haste. Changes from mo- 

 tnr cars to wagons, from wagons to 

 l);ick horses, are made with the least
