54 TREATISE ON FLY-FISHING. 



active. During the day, the larger sized fish move- 

 little from their accustomed haunts, but towards 

 evening and during the night, they rove in search 

 of small fish, insects, and their various larva?, 

 upon which they feed with eagerness. 



The young trout fry may be seen throughout 

 the day, sporting in the shallow gravelly scours 

 of the stream, where the want of sufficient depth 

 of water, or the greater caution of larger and 

 older fish prevent their appearance. Though 1 

 vigilant and cautious in the extreme, the trout is* 

 also bold, and active. A pike and a trout put 

 into a confined place together, had several battles 

 for a particular spot, but the trout was eventually 

 the master. This fish varies considerably in 

 appearance in different localities ; so much so, as 

 to induce a belief that several species exist- 

 Lord Home, however, who has paid much attention 

 to the subject, remarks, " I am much inclined to 

 think there is but one kind of river trout ; the 

 large lake trout may be different."
