FLIES AND FLY FISHING. 131 



It lasts until the end of October. It is chiefly out in the 

 middle of the day. Grayling occasionally take it very well. 



Hook, No. 12. 



Body of the lightest part of a mouse's fur. 



Any light blueish grey hackle. 



41. The Mid She. This fly, which somewhat re- 

 sembles the blue dun ; comes out about the middle of 

 September and lasts until the end of November. It is 

 partial to cold days. The rise generally lasts for half-an- 

 hour or so, in the same way as that of the iron blue. It 

 is a very good fly for both trout and grayling, and will 

 kill all day long, supposing the fish to have tasted the 

 original. 



Hooks, No. 10 and 11. 



For the body take a piece of stout gut, and having 

 flattened it between the teeth, soak it in the gut-dying 

 mixture, described in the chapter on tackle, until it be- 

 comes of a dirty olive green tinge, wrap this very neatly 

 and tightly round the hook, this gives the only good 

 imitation of the fly I know. 



A blue d.un hackle. 

 Tail : Two strands of same. 



Wings : A slip of any blueish grey feather of a medium 

 shade, set on very upright.
