204 DOMESTICATED TROUT. 



The nerves of smell in trout are large, and the sense 



of smell is probably well developed. Hence the use 



of fragrant oils and strongly scented bait in fishing for 



trout. 



Habitat. 



Brook trout abound chiefly in cold, swift-running 

 gravelly brooks ; but they thrive in all pure cold wa-

 are found in many ponds and lakes, which apparent 

 contradiction of terms has frequently led to confusion 

 among those unfamiliar with fishing. I may be, there-

 the name " brook trout " is not confined to trout caught 

 in brooks, but applies to all of the varieties of Sahno 

 fontmalis, whether found in brooks, ponds, lakes, or 

 rivers. Their range is very extensive, covering a wide 

 belt from one end of our continent to the other. In 

 phrenological language, their locality is very large, 

 which gives them a strong attachment to places. In 

 brooks, certain individuals will take up particular 

 holes or rapids for their abode, and occupy them for 

 months, and sometimes, I am inclined to think, for 

 years. 



In lakes and ponds, the shoals of trout have, like 

 perch and other fish, particular resting-places, where 

 they stay regularly. This is one reason why a person 

 acquainted with their haunts will go out and catch a 

 string of trout, while others, with better tackle and 

 equal skill, will fish a wiiole day for them in vain. 



The largest trout in brooks are found in the deep 

 wide pools in the warmer waters. The smallest ones are
