FLIES FOR MAY. 77 



No. 21. DOWNHILL FLY. 



This fly may be found upon the trunks of any 

 kind of tree or post near the water side. As soon 

 as it alights, it turns its head downward. It is 

 in season throughout May and June, and may 

 be used with most success on windy days. 



IMITATION. 



BODY. Orange floss silk tied with ash-coloured 

 silk thread, which may be shewn at 

 the tail and shoulders. 



WINGS. From a feather of the woodcock. 



LEGS. A furnace hackle, (i. e. a red cock's 

 hackle, with a black list up the 

 middle, and tinged with black also at 

 the extremities of the fibres). This 

 should be warped all down the body, 

 and the fibres snipped off again 

 nearly up to where the wings are set 

 on, leaving a sufficient quantity for 

 the legs uncut off.
