THE ENTOMOLOGY OF THE ERNE. 177 



member how you fish with twenty yards of 

 line out ; nothing that you could do would 

 keep your fly on the surface of the water, as 

 you do keep your trout flies, which really are 

 flies, and not shrimps. You do not try to 

 keep your salmon fly in such a position ; 

 half your line is in the water, and your fly 

 six inches under it. And think, too, how 

 you fish a trout fly ; you draw it across the 

 stream quietly, but to your salmon rod you 

 give a waving motion ; and it is to enable 

 you to do this without wearing a hole in 

 your trousers, that the salmon rod is fitted 

 with that round wooden button at the butt, 

 instead of a spike. And what effect do you 

 suppose this motion has upon the fly ? It 

 moves in a succession of jumps, like nothing 

 whatever that has life, except a shrimp, but 

 exactly like that. Depend upon it, your fly 

 is a shrimp." 



u 1 should not be surprised if you are 

 right," said the Squire. " I was remarking 

 the strange, life-like, jumping motions of my 

 fly the other day, from the top of that rock 

 at the Captain's Throw, and was thinking, 

 that, though they were the motions of an 

 animal, they were not the motions of a fly/'
