72 THE SCIENCE OF DRY FLY FISHING. 



metamorphosis. A few heavy drops of rain is followed or 

 accompanied by a rise ; this rise may be produced by an 

 upward movement of the pupae in response to the meteoro- 

 logical influences at work. Again, on certain summer 

 evenings, at about the same hour and for a similar period, 

 each evening will produce a general rise ; this, again, may be 

 due to the above cause. Again and again have I witnessed 

 the water at such times fairly boiling with the rising fish, 

 but it has been seldom that I have been successful in landing 

 even as much as a brace of fish, though after this excitement 

 has subsided, my Coachman, Silver Sedge, etc., have proved 

 most deadly. 



I am inclined to think that " bulging " may be produced 

 by a similar cause, that is, by the activity of the sub-aqueous 

 entomological life. 



The method by which the latest food taken by a trout 

 can be determined, is by holding the trout in one hand 

 and, with a firm upward pressure of the fingers of the other 

 hand along the lower sides of the abdomen of the fish 

 towards the gills, expressing, or forcing into the mouth,

The forenoon is, in my opinion, the most fascinating 

 time for fishing ; there is no arriere-pensee as to coming
