150 FLY FISHING FOE TROUT. 



it. Chetham's dressing is good, but is weak in 

 the wing, which should be finely pencilled and 

 not clear. Bowlker's is much better, and 

 Francis gives a dressing which is not unlike it. 

 Still the dressing has varied little in the two 

 hundred and forty years since Chetham 

 described it. Pritt in his Yorkshire Trout 

 Flies (1885) gives a good modern dressing : 

 wings hackled from inside a woodcock's wing 

 or partridge's neck or under a hen pheasant's 

 wing : body lead-coloured silk with a little fur 

 from a hare's face and the lower part green silk. 

 A hen partridge wing feather makes perhaps 

 the best wing, and heron herl the best body. 

 This is how Halford dressed the floating fly. 



The Shell Fly is, I think, in the early French 

 list. The following is a dressing given for 

 July : Body of green silk, inclining to golden 

 (tirant sur I'or), blue head, and wings of a 

 light-coloured feather. 



Olive Dun. 



The duns are difficult. From the time of 

 Cotton at any rate there have been two among 

 many which occur in all lists, the Blue Dun and 

 the Yellow Dun. Entomology admits the 

 existence of neither, but will only allow of an 

 Olive Dun and of the Blue Winged Olive The 

 Olive Dun varies greatly' in colour, from very 

 dark to quite pale : and I assume the Blue Dun 

 to be an imitation of the darker and the Yellow 

 of the paler flies.
