GKA VI.ING. 
Grayling; and even of flies, after which both are eager, the 
Trout pursues the larger kinds, while those sought for by the 
Grayling are of the very smallest, and a grasshopper is pre- 
ferred to all besides. It swallows earth also, with mud and 
sand, together with the smaller shells; and as in some rivers 
there have been found grains of gold mingled with the sand, 
and such have been found in its stomach, it has been said 
that these particles of metal were selected by choice, and to 
them the fish was indebted for the brilliant yellow which 
sometimes adorns its body and fins. The station which this 
fish assumes while waiting for prey is usually about mid-water; 
or if nearer the bottom, not close to it, and not far from a 
rock or stone; and from such places it more readily rises than 
goes down, but it returns to the same resort when success 
has crowned the excursion: and here again we find a contrast 
to the habits of the Trout, for while the latter is watchful, 
rapid, and wary in its actions as it deals with temptations, 
the Grayling, 
Unabashed, will dare, 
Baulked e’er so oft, the disappointing snare, 
Simple and bold: 
and hence it is that to the angler 
The Grayling yields no fame; too easy prey 
He turns Ms side of gold-bespangled grey. 
Asglbrs, a Poem. 
In its own sphere, however, the Grayling is capable of very 
swift motion, as is represented by Ausonius in its ancient name 
of Umbra: — 
BfTugicns oculos oeleri levis UTmbra natatu. 
The smooth-scaled Umbra as it passes by. 
Flits as a shadow o’er the gazer’s eye. 
Continuing the comparison of this fish with the Trout, Sir 
Humphrey Davy remarks that the latter in all its habits of 
migration runs upward, seeking the fresh and cool waters of 
mountain sources to spawn in; the Grayling, he believes, has 
never the same habit of running up the stream. He never 
saw one leaping at a fall, where Trout are so often seen; and
