THE GRAYLING. 373 



The name grayling is supposed to be a modification of the 

 words gray lines, in reference to the dusky longitudinal bars 

 along the body. 



" The grayling thrives best in rivers with rocky or gravelly 

 bottoms, and seems to require an alternation of stream and 

 pool. It has been considered that the large dorsal fin of the 

 grayling enabled it to rise and sink rapidly in deep pools ; but 

 this power would rather seem to be afforded by the large size 

 of the swimming-bladder. The very large dorsal fin, com- 

 pared to the small size of all the other fins, renders it unable

 down stream than up, and are never seen leaping a fall like a 

 trout." The largest grayling is recorded to have been caught 

 near Shrewsbury, in England, and weighed five pounds. 



Hofland says : " The same flies recommended for trout 

 may be used for the grayling, with the difference that for the 

 ' latter fish they must be smaller ; and all that I have previ- 

 ously said of fishing fine for trout will most especially apply 

 to the grayling — for, if you do not use a single hair, your gut 

 bottom must be as fine as hair and the color of the water you 

 wish to fish.'' 



. Satter says, " This fish is generally called a grayling until 

 full grown, then it is entitled to the name of umbra." The 

 appellation of umbra is derived from the swift motion of this 

 fish, it often darting like a shadow — 



" The umbra swift escapes the eye." 



" If a worm is used which they are very fond of in the 

 spring or the early part of a summer morning, if the water is 

 somewhat colored, then angle within a foot of the bottom, and 

 use a No, 9 hook to your line." 

 . Seth Green says of their gastronomic qualities: "They are
