110 THE FLY FISHER'S GUIDE. 



is taken with avidity by the trout and chub, being 

 a bait that they are remarkably fond of. These 

 flies are to be found in the greatest plenty on 

 sandy gravelly rivulets or brooks, and also on 

 some large rivers and pools ; but their favourite 

 haunts are most commonly the smaller streams, 

 where they are to be used with the best success. 

 They appear about the 20th of May, and continue 

 for nearly a month. The wings stand erect upon 

 the back, and vary, in the tints of yellow, in 

 different flies. The body is long, slender, and 

 taper towards the tail, from the end of which 

 spring the forked whisks, which, turning up to- 

 wards the back, give the name of green drake to 

 this fly. The body is made of hog's down, or 

 light bear's hair, intermixed with yellow mohair, 

 or of barber's yellow silk only, warped with pale 

 flos silk, and a small strip of peacock's harl for 

 the head. A bittern's hackle is acknowledged to 

 be the best imitation of the legs and dark stripes 

 of the body ; and for the tail the long hairs of 

 sable or fitchet are most appropriate.
