dun, mailo buz, and the inarch brown,, 

 are as good flies from the letter end of 

 Auguft, to the end of the feafon, as they 

 were in March and April ; and you may 

 at this time End your fport as regular 

 with them. 



In this catalogue there are a few ufe- 

 ful flies that have been noticed by others, 

 which, to omit, would on my part ap- 

 pear to doubt the existence cf, and con- 

 fequently tend to deprive you of the 

 advantage which may be derived by ufmg 

 them ; and was I to affet originality, 

 by inventirg new names for fuch flies, 

 I fhould feel myfelf guilty of an unwar- 

 rantable at of duplicity ; but if, by ex- 

 perience, you find that I have defcribed 

 a better method of imitating thofe few, 

 and have di reeled a readirr method of 

 .ing materials for the purpofe than 

 has hitherto appeared, my wifhes will be 

 amply gratified. 



I am, Sir. your r s, &c.
