FLIES 45 



the sky above and the water combined gives 

 a better guide, and that the converse of 

 Stewart's theory is the true one, viz. that a 

 ' certain colour is more deadly because less 

 readily seen/ and that movement is the 

 more visible sensation to the eye of a fish. 

 Thus let us give a few examples : 



We have instanced already ' black hackles ' 

 and ' white coachman' and 'grey spider/ We 

 have also found a flash of silver tinsel kill 

 best under a clear blue sky, but also well in 

 a dark spring water with a clear or sunny 

 sky. 



We have found ' red-body ' kill best in a 

 red water, i.e. porter or peat or dark amber. 

 (Both in salmon-fishing l and trout angling.) 



But we cannot agree with those who say, 



1 Thus a * Butcher ' in a coloured water, a ' Childers ' 

 when the evening sun goes ' back ' off a pool. But a 

 ' Jock Scott,' in my experience, has killed as well under 

 a cloudless sky and low water, or in a dark water, or 

 under a dark sky. Why ? Because we believe the com- 

 bination of colours which are useful are best harmonised 

 in the dressing of a 'Jock Scott.' We use 'Wee Jock 

 Scotties,' and they kill trout well. Dressing : guinea- 

 fowl hackle, i.e. black and white, two small shoulders 

 of jungle cock (from the top of the bird's head), body 

 black and yellow, wing pale transparent starling, or 

 ' what you fancy.'
