GREY DRAKE. 103 



sometimes called the Green Drake. The natu- 

 ralist may be highly gratified during a fine warm 

 day, in the end of May, by observing the man- 

 ner in which this singular insect breaks through 

 and flies from the case in which it has been 

 enveloped while in the stale of a maggot. The 

 wings are formed artificially of the light feather 

 of a grey drake, or wild mallard, dyed yellow ; 

 the body of yellow ram's wool, seal's fur, or 

 amber-coloured mohair mixed with a little fox- 

 down, or hog's wool, ribbed with pale yellow 

 and green silk, or the feather of a heron, to 

 imitate the joints of the fly's body ; the head of 

 peacock's herl, and the tail of three long hairs 

 from a sable muff, or the whiskers of a black 

 cat; the hook No. 6. This fly appears in the 

 end of May, but the principal time for using it 

 is from the first to the twelfth of June, from ten 

 in the morning till seven in the evening. 



Grey Drake. 15. 



This fly appears at the same time as the last 

 mentioned, and very much resembles it in shape ; 

 the wings are made of a dark-grey feather of a 

 mallard ; the body of light goat's hair, or white 

 ostrich's herl, striped with dark silk ; the legs 

 of a grizzle cock's hackle ; the head of pea- 

 cock's herl, and the tail of three hairs from a 

 sable murT or fitchew's tail ; the hook No. 6.
