TROUT FLY-FISHING IN AMERICA 



cause the temperature of the shallow water is so high that 

 trout seek the deep and cooler water and feed almost en- 

 tirely upon under-surface food. 



Trout, however, can be caught during this season, but 

 the angler must know when and where to cast his fly, and 

 he must be, except on rare occasions, satisfied with only 

 a few fish to his credit because the "proper time" to fish 

 is very limited. 



During the summer period trout seem to be more shy 

 than at any other time of the year, and I am satisfied that 

 this is due to the fact that the brightest light then prevails 

 and on this account shadows are more pronounced, prob- 

 ably scaring trout more quickly than any other one con- 

 dition. 



It follows, then, that the time to fish is in the very early 

 morning or the late evening when the light is the poorest. 

 And it is at such times that other conditions are more 

 favorable ; for instance, the temperature of the water is the 

 lowest in the early morning and next lowest in the late 

 evening. Then again, trout during the summer season 

 will only go into shallow water to feed at places where the 

 water is coolest. On this account it is necessary for the 

 angler to select such a place to fish. 



It is also necessary that the place selected to fish in 

 addition to having cool water be one where trout can find 

 food. 



Therefore in order to catch trout in the summer season 

 with any certainty the angler must fish when the light is
