138 SALMONIA. 



sun, and the gaudy flies when the dark 

 clouds appeared. Now I will tell you of 

 another principle which it is as necessary to 

 know, as the change of flies for change of 

 weather; I allude to the different kinds of 

 fly to be used in particular pools, and even 

 for particular parts of pools. You have 

 fished in this deep pool; and if you were 

 to change it for a shallower one, such as that 

 above, it would be proper to use smaller flies 

 of the same colour ; and in a pool still deeper, 

 larger flies ; likewise in the rough rapid at 

 the top, a larger fly may be used than below 

 at the tail of the water: and in the Tweed 

 or Tay, I have often changed my fly thrice 

 in the same pool, and sometimes with suc- 

 cess — using three different flies for the top, 

 middle, and bottom. I remember when I 

 first saw Lord Somerville adopt this fashion, 

 I thought there was fancy in it; but experi- 

 ence soon proved to me how accomplished a 

 salmon fisher was my excellent and lamented 

 friend, and I adopted the lesson he taught 

 me, and with good results, in all bright 

 waters.
