FLIES AND FLY FISHING. 133 



There are very many dressings made up for this fly, 

 but this is the only one I have ever seen that is a good 

 imitation of the original. 



44. The Willow Flies. I believe that these flies are on 

 every river in the world, more or less, during the whole 

 year. I do not know whether an entomologist would 

 dispute this, I only write as a fisherman, but I have seen 

 some of them at all seasons on waters in various parts. 

 When this fly's wings are closed it presents the appear- 

 ance of a little piece of stick. The female is larger than 

 the male, and is a good fly to use on cold days in Septem- 

 ber and beginning of October. The male fly should be 

 used also on cold days, from October until the end of 

 December is the time when it is on the water in the 

 greatest numbers, and during that time it is a great 

 favourite with grayling ; but I have never yet discovered 

 the water whether river, lake, pond, or brook, on which 

 this fly will not at times kill trout. 



44. The Female Willow. 



Hook, No. 10. 



Body : Fur from a mouse, this should be tied in from 

 the tail, half way up the hook, with a piece of flattened 

 gut, dyed lightly in the mixture mentioned in chapter III. 

 and very tightly wrapped on.
