382 THE DRY-FLY MAN'S HANDBOOK 



Good healthy yearlings of, say, six inches in length 

 are the best kind of stock to 

 Stocking with year- turn into most rivers, as they 

 lings. seem to get more easily ac- 



climatized and used to their 

 new surroundings than two-year-olds or larger fish. 

 They are, as being of smaller size, less well able to 

 take care of themselves than the two-year-olds, and 

 are more likely to fall a prey to the ravages of the 

 ubiquitous pike. Besides, too, one must remember 

 that the yearlings will take fully two years to grow to 

 a killable size in the river. If turned into stews and 

 moderately fed they should be about f lb. in weight 

 by the following spring, when they could be turned 

 in and in a few months would, under favourable con- 

 ditions, grow to an average of i lb. in weight. 



When turning out yearlings, two-year-olds, or larger 



fish it is very necessary to get 



Turning out fish. the temperature of the water 



in the fish-carriers uniform 

 with that of the stream. To effect this pour about 

 I ' one third of the water out of the carriers and fill up 

 with water from the river. Let them stand for some 

 time, then empty half the contents of the carriers and 

 fill up again. Continue this until the temperature of 

 the water in the fish-carriers, as indicated by the ther- 

 mometer, is identical with that of the stream. Then 

 turn out the fish. 



Mr. Corrie is further of opinion that "In many 

 cases, too, one has to consider the differing qualities of
