THE FLY FISHER'S GUIDE. 69 



rich yellow of the sides and belly, produce a 

 fine effect. At this time it is hog-backed, like 

 most other fish. 



The variety in the shape and colour of trouts, 

 which are taken in different rivers and pools, has 

 induced some persons to imagine that there are 

 three distinct kinds of this fish, viz., the red, the 

 yellow, and the white, the former of which ranks 

 highest in estimation ; but the more generally 

 received and most probable opinion is, that this 

 difference arises from the quality of the food, or 

 from the water which they inhabit being impreg- 

 nated with some substance capable of producing 

 this effect. Certain it is, that their haunts, vo- 

 racity, and modes of feeding, are every- where 

 alike. 



They spawn about the latter end of October or 

 beginning of November, at which time they are 

 unwholesome, and not worth eating. At this 

 season they constantly work up the stream, in 

 order to find proper situations for spawning; 

 for which purpose they generally prefer brooks.
