genera, the Butterfly and the Mixed wing, 

 each containing several species : but, some 

 two or three vears before the date of these 

 conversations, the fishermen had added to 

 these a third genus of fly, differing in every 

 particular from the other two ; and this, 

 from its inventor, was generally known by 

 the name of " the Parson." 



The Butterfly is distinguished readily from 

 all others by its under wings, which, being 

 made of the tippet feather of the golden 

 pheasant tied on whole, give it the appear- 

 ance of a copper-coloured butterfly. In all 

 the species of this fly alike, the tail is, or 

 ought to be, of yellow topping. The tip is 

 sometimes plain, but, more generally, it is 

 formed by two or three rounds of black 

 ostrich or peacock's harl ; the body is inva- 

 riably of floss-silk, hackled, and turned with 

 tinsel or twist, which is of gold or silver, ac- 

 cording to the colour of the body : this 

 colour, which should be changed according 

 to the colour of the sky or water, indicates 

 the different species of the fly. These are as 

 follows : —
