station without delay to the water which they are 

 intended to stock, and there liberated. 



Experience shows that if the precautions I have 

 mentioned are observed, the fish are none the worse 

 for their experiences in overland transport. 



The larger the fish the greater of course is the 

 quantity of water required for travelling them. The 

 expense, therefore, of transporting two-year-olds is 

 proportionately heavier than in the case of yearlings, 

 and the risk is more appreciable. 



The danger of overcrowding in the cans is greater 

 for rainbow trout than for Fario, although, when 

 at liberty, rainbow have f broken the record ' for 

 thriving in water which is subject to considerable 

 variation of temperature. 



One of the perils of travelling is, lest the carriers, 

 on a change of trains, should by accident be left 

 standing still exposed to the heat of the sun for some 

 time ; and precautions must be taken to prevent such 

 an accident as this from happening. 



As I have said, any great alteration of temperature 

 is injurious if it is very sudden. Accordingly, before 

 liberating the fish, it is necessary gradually to pour 

 from the carrier the water in which they have 

 travelled, substituting water from the stream or lake 

 which you are stocking. This is especially desirable
