A A, C C. Tank. 



A, B, A. Lid to tank. 



A A. Junction of tank with lid. 



In travelling long distances, I take, besides the 

 tank,* a water-pail, a bag of ice, tin dipper or bellows, 

 and a sponge. The ice will be all needed before night, 

 if the weather is warm. The pail is a convenience in 

 various ways, the dipper or bellows t is for aerating 

 the water, and the sponge is for the floor of the car, 

 if the water slops over. Be careful to have plenty of 

 help when you load into the car, and also at every 

 change of cars, for, different from other merchandise, 

 an upset is often a total loss.f 



Keep the temperature of the water very low all day 

 with ice, — using large pieces when standing still, and 

 small pieces when in motion, as the large pieces are 

 then apt to bruise and kill the fish. Do not change 

 the water en route, but give it a thorough aeration once 

 in half an hour. The aerating will be sure to keep 



* The Troutdale Transit Tank is recommended as an excel- 

 lent thing to carry live fish in. See Dr. Slack's Catalogue of 

 fish culturists' apparatus. A common flour-barrel, well soaked, 

 with floats on the top of the water to prevent slopping, is a very 

 good impromptu affair for carrying live fish. 



t A common hand fire-bellows is as good an extempore aerat- 

 ing machine as can be found.
