172 SALMONIA. [SEVENTH DAY 



contains principally trout ; the Clun, both trout and 

 grayling; but the fish are more abundant in the 

 meadows, between tin's place and Downton, than in 

 other parts of the river ; for above, the stream is too 

 rapid and shallow to be favourable to their increase ; 

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

 too abundant in coarse fish. 



POIET. I cannot understand why the grayling

 being an Alpine fish, and naturally fond of cool water, 

 it might have been expected among the Highlands. 



HAL. I formerly used to account for this, by 

 supposing it an imported fish, and not indigenous; 

 but, in some of my continental excursions, I have 

 seen it living only under such peculiar circumstances,

 serves me, the rivers that contain it are near the ruins 

 of great monasteries, the Avon near Salisbury,
