The wings' of this fly being diapha- 

 nous, gives you the advantage of ufmg 

 any light color feather you chufe ; I 

 know a good angler who invariably ufes 

 the pith of the fecond quill of a goofe's 

 wing for them. 



About this time the dun becomes a 

 morning and evening fly, and fhould be 

 made of pale otter's, or hedge-frog's fur. 

 In bright weather the marlo buz fhould 

 be varied from iilver to gold twift, on 

 a body made of peacock's orl. The 

 cow-dung fly continues all the fummer 

 months, but are not worth your notice 

 after the iron-blue fly makes its appear-- 



I am, Sir, 

 Your's, &c
