dye. Length of case, three-quarters to an inch, cylin- 

 drical, and rather bowed ; is studded rough on the out- 

 side with particles of sand, which presents a piece of 

 tessalated work would puzzle a Roman. They lie un- 

 der stones in shallow currents that run over sand and 

 gravel, which their rough-cast coats exactly resemhle, 

 and keeps them safe at anchor. Several may oft be 

 found under the same stone. They are good for trout 

 and old smelt in April and May, fished on the fly 

 hooks. They may be kept in water pots, for use, or 

 until they fix and hatch, by keeping the water fresh ; 

 close thick woollen bags (to exclude the air) are the 

 best to take them out in, now and then dipping them 

 in water. 



9TH. FRECKLED DUN CREEPER (stickbait). 

 Length, half an inch. Head, shoulders, and legs, 

 black ; body, a light blue dun. The vegetable appen- 

 dages impart a dye which freckles or darkens the 

 stickbait tribes. Length of case, about three-quarters, 

 with its appendages of stems, etc., to an inch and a 

 quarter. Their buoyant dwellings compel them to choose 

 still waters, but in their rambles for fixing they oft 

 may be seen propping and contending against the 

 stream. 



10xH. LEAST FRECKLED DUN CREEPER. Length, 

 better than one-eighth. Head, shoulders, and legs, 

 black ; body, leady. Case, near a quarter, covered 

 smooth with fine brown soil, and looks like a short 

 piece of rusted wire.
