LETTER VII. 



pQ #*##* ****** 



.Dear Sir, 



Being now arrived at that 

 part cf the arnufcment, which, to excel 

 in, will require your niceft {kill, I 

 mud here inform you, that no precifc 

 direction can poffibly be given for the 

 iize of flies, it depends fo much on the 

 flate of the water you fiih upon, that 

 you mud be direfted by your own ob- 

 iervation, in which the following hints 

 may affid you. Rapid flreams, that are 

 not deep, and run over fine gravel, are 

 generally very clear, particularly near 

 the fource; on fuch water your fly fhould 

 be made on a hook No. 9 or ICK For 

 flow deep dreams that are generally dii- 

 colored, a fly dreffed upon a hook No. 

 5 or 6 } is leldom too "large. 



My
