THE ANGLER AND HIS LURES 141 



face. This is .what the fish sees as he swims in 

 a horizontal position. 



Scores of times has the dry fly-fisher seen the 

 trout come up to his fly, refuse, and sink back to 

 the spot from which he came. The fish may do 

 this once or twice, and subsequently ignore the 

 artificial fly as it passes over him, but he may 

 still continue to rise to the natural fly. The 

 trout is not frightened by the artificial fly, he 

 simply recognises that it is not what he wants 

 and so ignores it. On another occasion a fish 

 may come up to a fly thrown in the same manner. 

 This he does not refuse, as described above, 

 but suddenly turns off and disappears. I think 

 the explanation is that, on this occasion, the 

 angler has come into the fish's "window" in 

 consequence of the altered position of the fish 

 in the water. The top photograph on the plate 

 opposite page 140 illustrates this point. The 

 moral for the fisherman is to keep well down, 

 even when below the fish, unless concealed 

 against a suitable background. 



The under-water appearance described up to 

 this point only applies when the surface of the 

 water is still or moving gently with an unbroken 

 surface.
