SYSTEM AND CLASSIFICATION 



the head, and most of them two wisks at the tail. 

 They are mostly brown in color, and are very quick 

 runners, both in the water and on land. 



Second: Drakes are all bred in the water and 

 are of various sizes and colors, abounding in all their 

 varieties in vast numbers, from the large green 

 drake to the very tiny white drake. Their move- 

 ments are sluggish on land; they will even allow 

 themselves to be taken up by the wings. They are 

 not so hardy as the browns. Their shoulders and 

 bodies are exposed; but nature has furnished them 

 with a temporary covering, which they cast off 

 when the weather suits, bursting open the covering 

 at the shoulders and coming out a different color. 

 They have close, thick shoulders, and smooth, taper- 

 ing bodies which curve upward like the feathers in 

 the tail of a drake. They have a pair of smooth, 

 oblong wings, which, when at rest, stand upright 

 close together; a small wing stands at the root of 

 each large one, and there are two or three hairs in 

 the tail. Some species hatch out in two or three 

 weeks. Others continue hatching through the en- 

 tire summer. 



Third: The duns have two long feelers, small 

 heads, short necks, and small, jumped-up shoulders. 

 They have two pairs of large wings, set near the 

 head; the under wings of some fold double, and all 

 lie close together along the back and slope down 

 over the sides, growing broader at the ends. Duns
