HOW TO TIE FLIES. 



The wings of a dun are more or less opaque, and are, 

 for the most part, well imitated by the feathers usually 

 employed. The wings of a spinner, on the contrary, 



are, as a rule, like films of crystal, either smooth or 

 frosted (asit were), to give an effect which might perhaps 

 be described as " c * nn ' l * r a^^n-n^-nnao " 



To the best of my judgment, the proportions impor- 

 tant to fly dressers of these upwings appear somewhat 

 as follows : 



Of both dun and spinner, the length of the wings from 

 base to tip is equal tothe total length of head, thorax, 

 and abdomen (body). 



Of a dun, the length of the whisks is to the total length 

 of head, thorax, and abdomen, as 7 to 6, approximately. 



In a spinner this same ratio is, approximately, as 7 to 4,
