172 SALMONIA. [SEVENTH DAY. 



contains principally trout ; the Clun, both trout and 

 grayling; but the fish are more abundant in the 

 meadows, between this place and Downton, than in

 and below, it is joined by other streams, and becomes 

 too abundant in coarse fish. 



POIET. I cannot understand why the grayling

HAL. I formerly used to account for this, by 

 supposing it an imported fish, and not indigenous;
