APRIL. THE YELLOW DUX. 207 



March he need not go far beyond one or two shades of 

 the blue dun, the March brown, the red spinner, the cow- 

 dung, and the coch-y-bondu. The rest he may have, these 

 he must. 



APRIL. For this month the best flies are those which 

 I have named for the last one, all of which may still be 

 depended on. But there are many other excellent flies 

 which make their appearance this month. Chief amongst 

 them is 



The Yelloiv Dun, yellow-legged bloa of Jackson, hare's 

 ear and yellow, &c. (see Plate VII. fig 6, p. 185). I am 

 almost inclined to think that the yellow dun is but a 

 modification or sort of second crop of the blue dun ; at 

 any rate it bears a very close relationship to it. It seems 

 to prefer warmer weather than the blue dun, and comes 

 on more during the middle of the day than at morning or 

 evening. It should be dressed of the same size as the 

 blue dun, and sometimes for fine water a size or two 

 smaller. The body is of an olive-yellow. Take a shred 

 of yellow silk, wax it lightly with a bit of the white wax 

 (see white wax receipt), and then unravel it, and wind it 

 on the hook for the body. The centre of the silk which 

 has not been touched by the wax will, as I have shown in 

 the blue dun, show a brighter coil here and there, which 

 will give the brighter yellow rings or joints of the body. 

 Contrive, if possible, when thus laying it on, to make the 

 yellowest portions show on the belly, and the darker or 

 more olive hue caused by the wax more visible upon the 

 back, as the back of the fly is of a darker tinge than the 

 belly. If this be neatly and properly done, it gives a 

 capital imitation of the body. Some writers recommend 

 mohair and crewels, but this cannot be a good imitation > 

 because the body is smooth and shiny, and not in the least 

 rough ; added to which, crewels and such materials should 

 never be used for these flies if they can be avoided, as.
