226 FLY-FISHING. 



Imitation. 



Body. — Work in a little tuft of green at the tail, 

 and then finish the body of sandy-colored mohair. 



Wings. — ^A light brown mottled hen's feather, to 

 lie flat. 



Legs. — A pale ginger hackle. 



The body of the male is yellow, without the green 

 tag. 



No. 13. The Yellow Dui^^. 



This beautiful ephemera is one of our very best 

 flies. There are several varieties, and some of them 

 ^re an inch in length. It changes to a spinner, very 

 similar to the metamorphosis of the bhie dun (No. 2), 

 only lighter and yellower, and should be so tied. 



Imitation. 



Body. — Yellow mohair spun very thinly on pale 

 blue silk. 



Wings. — From the lightest part of the feather of 

 a robin's wing. 



legs. — A pale yellow dun hackle. 



This fly must not be finished off at the head with 

 the bhie silk, but a yellow must be tied in for the 

 purpose when the body is done. 



No. 14. The Ikois- Blue Dun. 



This is one of the smallest of the ephemeridce.^ 

 but not the least useful. It lives only two or three 

 days before changing its coat, when its body becomes 

 almost white, and its wings transparent.
