SALMONIA. 



HAL, It is a trout, and not a grayling. 



PHYS. How do you know ? 



HAL. By his mode of rising. He is lying 

 at the top of the water, taking the flies as they 

 sail down by him, which a grayling scarcely 

 ever does. He rises rapidly from the bottom 

 or middle of the water, on the contrary 

 darting upwards, and, having seized his fly, 

 returns to his station. There ! a grayling has 

 risen. I do not mean, however, that this habit 

 is invariable; I have sometimes seen trout 

 feed like grayling, and grayling like trout, 

 but neither of these fish emits bubbles of air 

 in rising, as dace and chub do. 



GRAYLING. 



PHYS. 1 have one ! He has taken my 

 blue dun, and must be a small one, for he 

 plays with no vigour.
