half, and is very generally found in all our clear ftreams, 
lying at the bottom, either under a flone, or upon the 
gravel. It depofits its fpawn in the fand, in a receptacle 
hng for the purpofe ; and its concern for its future pro- 
§ e ny is fuch, that with reluctance it leaves the fpot from 
^hich it is to rife. The frefh water infe£ts are its food ; 
tue pulex aquatilis being frequently found in its flo-
