fore extraordinary that it is to be found in 

 the greatest quantities on cold windy days, 

 being hardly ever to be seen in mild warm 

 weather. It is an early fly, making its appear- 

 ance about the first week in March, at which 

 time it remains on the water during the 

 whole of the morning. It is extremely dif- 

 ficult to meet with a feather of the exact 

 shade, or sufficiently delicate in the fibre for 

 the wings of this fly ; it is therefore better 

 to make it of a pale blue dun hackle, and 

 use it as a dropper. The body is composed 

 of the blue fur from a water rat, mixed with 

 a small proportion of lemon coloured mo- 

 hair. As the wings of this fly stand erect 

 on the body, a cock's hackle is preferable to 

 that of a hen, not being so liable to yield to 

 the action of the water.
