Then he girds himself for the new fight and follows the track of the second
enemy across the fens. Here is Hrothgar's description of the place where

The dim land that gives shelter to the wolf,
The windy headlands, perilous fen paths,
Where, under mountain mist, the stream flows down
And floods the ground. Not far hence, but a mile,

A wood fast-rooted overshades the flood;
There every night a ghastly miracle
Is seen, fire in the water. No man knows,
Not the most wise, the bottom of that mere.

Will rather die of thirst upon its bank
Than bend his head to it. It is unholy.
Dark to the clouds its yeasty waves mount up
When wind stirs hateful tempest, till the air
Grows dreary, and the heavens pour down tears.[9]
