150 SALMONIA. [SIXTH DAT. 



and begin; but whilst you are preparing, I will 

 mention a circumstance which every accomplished 

 fly-fisher ought to know. You changed your flies on 

 Saturday with the change of weather, putting the 

 dark flies on for the bright gleams of the 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 

 success using three different flies for the top, middle, 

 and bottom. I remember that when I first saw 

 Lord Somerville adopt this fashion, I thought there 

 was fancy in it ; but experience 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. 



POIET. I will try the correctness of your principle.
