The next, pursue their rocky-channel'd maze,
Down to the river, in whose ample wave
Their little naiads love to sport at large.
Just in the dubious point, where with the pool
Is mix'd the trembling stream, or where it boils
Around the stone, or from the hollow'd bank
Reverted plays in undulating flow,
There throw, nice-judging, the delusive fly;
And as you lead it round in artful curve,
With eye attentive mark the springing games
Straight as above the surface of the flood
They wanton rise, or urged by hunger leap,
Then fix, with gentle twitch, the barbed hook:
Some lightly tossing to the grassy bank,
And to the shelving shore slow-dragging some,
With various hand proportion'd to their force.
If yet too young, and easily deceived,
A worthless prey scarce bends your pliant rod,
Him, piteous of his youth and the short space
He has enjoy'd the vital light of heaven,
Soft disengage, and back into the stream
The speckled captive throw. But should you lure
From his dark haunt, beneath the tangled roots
Of pendant trees, the monarch of the brook,
Behoves you then to ply your finest art.
Long time he following cautious, scans the fly;
And oft attempts to seize it, but as oft
The dimpled water speaks his jealous fear.
At last, while haply yet the shaded sun
Passes a cloud, he desperate takes the death,
