54 On Stocking. 



stretches of sluggish water immediately above the 

 mouths of the principal streams running into 

 them ; these stretches of water have sometimes 

 pike and frequently perch, and are therefore un- 

 suitable for yearlings, but as the feeding is usually 

 more abundant in such places than elsewhere, or 

 than in the loch, they are just the spots to choose 

 for turning in two-year-olds, while higher up the 

 principal burns there is often found that sequence 

 of pool and shallow so suitable for yearlings ; 

 higher up again there are gravelly places where 

 fry can find food and shelter, and many of the 

 smallest burns have clear springs where Ova may 

 be laid down, if on the point of hatching, without 

 any redd or other preparation, and with the cer- 

 tainty of success. With conditions similar to the 

 above, the greatest economy will be obtained by 

 a nice adjustment of numbers of each of the four 

 classes, viz., eggs, fry, yearlings, and two-year-olds, 



REDDS. 



The formation of redds is a very simple matter, 

 nevertheless much skill and local knowledge may 

 be advantageously exercised in the choice of posi- 

 tions. 



A careful survey of the stream or river should 

 first be undertaken, and the amount of suitable 

 shallows for rearing fry carefully noted. The
