80 SALMONID^. 



Wye. In Derbyshire, in the Dove. In Merionethshire, 

 in the Dee, between Curwen and Bala. In Lancashire, in 

 the Ribble. In Yorkshire, in the Derwent, the Ure, 

 the Wharfe, and the Wiske, near Northallerton. Dr. 

 Heysham says it is occasionally taken in the Eden and 

 the Esk in Cumberland. It is not found, that I am aware, 

 either in Ireland or Scotland ; Mr. Low, however, includes 

 this fish in his Fauna Orcadensis, and it is known to be 

 plentiful in Sweden, Norway, and Lapland. The pecu- 

 liarity of the local distribution in this country gave rise 

 to the supposition that the Grayling had been originally 

 introduced by the monks, as a fish worth cultivating ; many 

 of the rivers containing the Grayling being near the remains 

 of great monasteries. But two circumstances affect this solu- 

 tion : it would be very difficult to bring this fish alive from 

 the Continent to this country ; and it is not found in the 

 rivers of Kent, Dorsetshire, Devonshire, or Cornwall, where 

 monastic establishments were formerly numerous. 



The Grayling thrives best in rivers with rocky or gravelly 

 bottoms, and seems to require an alternation of stream and 

 pool. According to Sir Humphrey Davy, who has given a 

 good history of the Grayling in his " Salmonia," this fish was 

 introduced into the Test, in Hampshire, from the Avon ; 

 and the former river, in particular parts, appears to suit it 

 the better of the two. Large Grayling are, however, occa- 

 sionally taken in both these waters, which are particularly 

 resorted to by the southern anglers. Three Graylings, 

 weighing together twelve pounds, were caught by Thomas 

 Lister Parker, Esq. in the Avon, near Ringwood. A Gray- 

 ling of four and a half pounds' weight has been killed in the 

 Test, and one of five pounds is recorded to have been caught 

 near Shrewsbury.
