no THE WAY OF A TROUT WITH A FLY 



But in July I found it ignored, as were all other patterns, 

 till I put on one which I had casually tied with exactly the 

 same materials with the addition of three strands of light 

 heron herl dyed greenish-yellow olive. This pattern proved 

 very attractive, and each year since I have proved its 

 efficiency when the July dun is on. This is how I came to 

 discover it. 



3. JULY DUN. 

 One July morning some few years back I was occupying 

 a few minutes while waiting for breakfast at my Hampshire 

 inn, by adding to my already excessive stock of trout flies, 

 when the sight of a thin wing covert feather of a heron, 

 dyed a medium greenish-yellow, tempted me to tie in a 

 00 size a sort of pale rendering of a heron herl bodied fly 

 which, as the Rough Olive, had long served me well at 

 the opening and close of successive trout seasons. So I 

 varied a pattern which had served me well in a variety of 

 shades all through the season by giving it a body dubbed 

 with three strands of the herl. Here is the dressing: 



Hook. — No. 00 down-eyed Bartleet's shape, B. 7362. 

 Tying Silk. — Yellow. 



Hackle and Whisk. — Greenish-yellow dyed cock. 

 Body. — Three strands of thin heron herl from outer wing 



covert dyed greenish-yellow. 

 Rib. — Fine gold wire. 

 Wing. — Starling, darkish. 



I liked the look of the result enough to dress a second 

 to match the first. 



It was a sunny morning with a faint air from the south- 

 east stirring when I got down to the water-side, and I 

 chose to open operations on a stretch of the east bank of 

 the Itchen which runs for a couple of hundred yards from 

 slightly north of west to slightly south of east. It is
