60 FOSTER'S LIST OF REFINED AND IMPROVED 



" We can strongly recommend Foster's Red Caterpillar. He has frequently 

 afforded his customers great success with it." Country. 



APRIL. No. 1, Yellow Dun;* No. 2, Pale Blue Dun; 

 No. 3, Sand Fly ; No. 4, Grannum ; No. 5, Foster's Inter- 

 mediate ; * No. 6, Iron Blue Dun.* 



The Yellow Dun of April makes its appearance in great numbers on 

 cloudy and cold days from April to September. We have found this 

 fly the most deadly " artificial " we ever threw. The legs are that 

 beautiful olivy-yellow shade so difficult to imitate ; the body is of a 

 smoky-blue colour, through which the lemon-tinted ribs protrude from 

 head to tail, and the wings are of the ordinary dun transparent hue. 

 This fly will appear much darker in colour when the season is backward 

 and cold. In this emergency we use a copy darkened by introducing 

 a rust-like shade upon the body, which has a good effect when held 

 between the eye and the light. The fly marked as our Intermediate 

 is intended to represent the middle or intermediate stage of all the 

 "duns" whilst in the act of changing their skins, prior to their 

 reappearance as Spinners. The Pale Blue, Sand Fly, and Green-tail, 

 or Grannum, are all good flies, both in spring and autumn. The Iron 

 Blue makes its first appearance in this month, but is much more 

 numerous in that following. 



MAY.-No. 1, Yellow Dun ; No. 2, Black Gnat ; No. 3, 

 Little Yellow May Dun ; No. 4, Oak Fly ; No. 5, Yellow 

 Sally ; No, 6, Mulberry Bumble. 



The Yellow Dun of May kills well on fine warm days, and is much 

 smaller and lighter than that of April. These, in common with all spring 

 flies, kill well at times in the autumn, the weather and water then being 

 about the same temperature. The black gnat is a very small fly, which 

 is a great favourite with both trout and grayling when fully on the 

 water. The usual copies of these little creatures are, generally speaking, 

 much nearer the size of a blue-bottle than that of a gnat. The same 

 observation also applies to the Iron Blue, Red Ant, and Little Chap ;
