TACKLE 



thing I ever saw in nature. I would like to see a 

 Jock Scott or Silver Grey bug. We don't have 

 them in American rivers, yet these flies are ex- 

 cellent here. I do not claim that we know all 

 about the subject we are evidently very ignorant 

 on its real scientific side but I hope the facts 

 given in this book will promote a more intelligent 

 and rational study of the subject. I do not be- 

 lieve it is a very difficult one to completely under- 

 stand if we apply some real scientific work to it, 

 and so far from reducing the interest in the sport 

 it will vastly increase it for any intelligent angler. 

 Personally I shall not be satisfied to fish and not 

 know the laws which govern the subject. I want 

 to know, and I want the fish this knowledge en- 

 ables me to catch. I would arrange the factors 

 governing the attractiveness of a fly in the follow- 

 ing order of relative importance: 



(1) The light-effects of the fly, above and below 



the surface. 



(2) The way the fly is cast and manipulated, 



including where the fly is placed relative 

 to the fish. 



(3) Visibility of the leader to the fish. 



(4) The size of the fly.
