52 THE BLUE DUN. 



dark red ; the chest, from whence the legs proceed, 

 is of a dull black ; the tail part of the body the 

 same, ribbed with dull green yellow ; of which 

 colour are the six legs and two whisks at the tail. 

 At the beginning of March the wings and legs 

 are lighter, the body of an ash colour; in April 

 the wings are still lighter, and the body quite 

 yellow. 



The principal season is all March, till about the 

 middle of April. Its general time of appearing is 

 from about eleven till three o'clock. They are 

 then larger than when they become more nu- 

 merous ; and are more plentiful, and are on the 

 water earlier and later, in mild days, than in cold 

 weather. 



Artificial. In February and March, make the 

 wings of any weak feather, from about the rump of 

 a blue dun hen, which is the same colour inside 

 and out ; or from the inner part of the wing of a 

 starling. For the body, use the under blue dun fur 

 of a fox, or light lead-coloured shalloon ; tie and 

 rib with split primrose silk, and pick out the dub- 

 bing, so that the wings may appear. Legs, a dun 

 hackle, yellowish at the point : the forked tail of 

 two of the finer fibres from the feather of which 

 you make the wings, which, as the flies grow 

 lighter, may be made from the light part of the 

 starling's wing ; mix some fine greenish yellow wool 

 with your fur, and use yellow silk. In April, 

 martens' yellow fur, and bright yellow silk.
