WORMS DESCRIBED. 307 



grey drake are similarly incased in pieces of rushes, 

 dried stems of weeds, &c. until they become flies : 

 those look like maggots or grubs, of a yellowish 

 colour, that are found in cases, or husks of wood, and 

 stones 5 and those incased in rushy or weedy husks, 

 are, invariably, green. Case-worms, rough-coats, &c. 

 which were formerly used in angling for Roach, Dace, 

 and Chub, but, in respect to their value as bait for 

 fishing, compared with what the modern anglers use, 

 they are hardly worth naming or describing, yet are 

 extremely curious as a natural production. The cad 

 may be found on the margin of small rivers (the banks 

 of the New River and the Lea abound with them) 

 adhering to the bank sides, or a little below the sur- 

 face, and, sometimes, on the top, during the Spring 

 months. This insect is about three quarters of an 

 inch long, enclosed in a rough husk or case, the size 

 of a large tobacco-pipe stem, and has the appearance 

 of small pieces of decayed sticks, &c. As the weather 

 becomes warm, they break through the case, and are 

 a complete fly. — Note. In the New River, and some 

 other small streams, I have found the Roach take a 

 cad freely in the month of April, and also Trout will, 

 sometimes, prefer it to a worm. When you bait with a 

 cad, break the husk in which it is enclosed^ carefully 

 take out the cad and place it on the hook, in same 

 way you do a gentle for Roach 3 but, for Trout, put two 

 on, one to cover the shank of the hook, and the other 

 to cover the point and bend.
