frequent the rivers are produced from 

 them. Some are found among the 

 the weeds in flanding waters, which 

 are generally tinged green, inclofed in a 

 very rough {hell; but that which is 

 mod ufeful to an angler, is found in 

 ftony brooks, or gravelly rivulets, clofe- 

 ly adhering to any folid fubftance it 

 finds at the bottom; though fometimes 

 among the loofe gravel, with the thtca %

 covered with fand^ or very fine gravel. 



When taken out of the water, they 

 may be preferved a month, by putting 

 them in a woollen bag, with, or with- 

 out mofs, upon a cool floor. If the bag 

 fhould become too dry, care mud be 

 taken not to ufe too much water to 

 damp it again, as thefe infe&s cannot 

 endure their native element, after they 

 have been taken from it four days ; fUll 

 they muft not be expofed to the othei- 

 extreme.
