Appendix. 147 



morfel, it may be, ftill, as long as there is a veftige of 

 the old material remaining it will cling to the hook. 



In proceeding to give a lift of flies which, from ex- 

 perience I have found to kill the beft, I do not prefume 

 to afTert that there are not others equally good, or that 

 all I here recommend will kill fifh in every river and 

 ftream in England. To fay that I prefer them myfelf 

 is, I conceive, the beft reafon I could advance for ad- 

 viling others to make a trial of them too. 



I might have fwelled the lift to double the lize, but 

 I have refrained from doing fo from the conviction that 

 when feveral flies of a different clafs are on the water, 

 to felefl the beft, and have nothing to do with the 

 remainder, is the wifeft plan to adopt. 



Although I have given the flze of the hooks, which 

 is afcertained by the number, commencing, in the cafe 

 of the fneck-bent, with the largeft, No. I, and ter- 

 minating with the fmalleft, No. 1 2, it does not follow 

 that it fliould be ftridlly adhered to. On the contrary, 

 it muft be determined in great meafure by the height 

 and colour of the water.
