made artificially ; the wings of a dark drake's feather, 

 the body of the red fur of a squirrel, and a red cock's 

 hackle wrapped twice or thrice under the wings for 

 legs ; the hook No. 7 or 8. This fly is to be fished 

 with from ten o'clock in the morning till three in 

 the afternoon. 



BLUE DUN. No. 2. 



This fly is found on most rivers, and is in 

 appearance one of the most delicate insects that 

 frequent the water; and, what is rather extraor- 

 dinary, it is more numerous, and the fish take it 

 best, in dark cold weather, being but seldom seen 

 when mild and warm. It appears early in March, 

 and is a good fly throughout the year. The wings 

 stand upright on the body, and are to be made of a 

 feather from a starling's wing, or a pale blue feather 

 from under the wing of a duck widgeon ; the body 

 of the blue fur of a fox, or water rat, or squirrel, 

 mixed with a small proportion of yellow or lemon- 

 coloured mohair ; and a fine blue cock's hackle for 

 legs ; the tail is forked, and is to be formed with 

 two fibres from the same feather as the wings are 

 made of; the hook No. 9. It may be used from ten 

 o'clock in the morning till three in the afternoon ; 

 but the best time of the day is from twelve till two, 

 particularly in March and April.
