138 PRACTICAL TROUT CULTURE. 



dividing the can into two divisions, a matter of 

 importance when fishes of different ages and can- 

 nibalistic propensities are to be transported. 

 Should the weather be warm, a tray with perfor- 

 ated bottom is fitted to the top and filled with ice, 

 the drip from which will keep the temperature 

 sufficiently low. Around the top of the can are 

 inserted windows, as they may be termed, of fine 

 wire gauze. The whole is surrounded by a conical 

 cover. The air-pump is attached to the sides of 

 the can by thumb-screws, so that with the india- 

 rubber tube it may be removed and packed inside 

 on a return trip. We have been frequently obliged 

 to leave home with fish by daybreak, in order to 

 reach a distant point during the same day. To 

 capture and count the fishes, sometimes amounting 

 to many thousands, immediately prior to starting, 

 would necessitate early rising, a luxury which we 

 by no means enjoy. The windows of wire gauze 

 are now of use. The fish are taken, counted, and 

 placed in the tank over night, the air-pump is 

 removed, and the can, with cover firmly attached, 

 is sunk in swift-running water, which, passing 

 through the windows, will keep the captives in 

 good order. The only objection to these windows ' 

 is that during transit over rough railroads the
