190 SALMONIA. [SEVENTH DAS:. 



in Wiltshire. I know of no river containing them 

 on the north coast west of the Severn : there are very 

 few only in the upper part of this river, and in the 

 streams which form it in North Wales. There are a 

 few in the Wye and its tributary streams. In the 

 Lug, which flows through the next valley, in Hereford- 

 shire, many grayling are found. In the Dee, as I 

 have said before, they are found, but are not common. 

 In Derbyshire and Staffordshire, the Dove, the Wye, 

 the Trent, and the Blithe, afford grayling ; in 

 Yorkshire, on the north coast, some of the tributary 

 streams of .the Eibble, and in the south, the Ure, the 

 Wharfe, the Humber, the Derwent, and the streams 

 that form it, particularly the Eye. There may be 

 some other localities of this fish unknown to me ; but 

 as I have fished much, and inquired much respecting 

 the places where it is found, I think my information 

 tolerably correct and complete. 



PHYS. Is this fish to be fished for in spring? 



HAL He is to be fished for at all times, for he is 

 rarely so much out of season as to be a bad fish ; and 

 when there are flies on the water, he will generally 

 take them : but as the trout may be considered as a 

 spring and summer fish, so the grayling may be 

 considered as a winter and autumnal fish. 



PHYS. Of course the grayling is taken in spring 

 with the same imitation of flies as the trout ?
