‘A boding silence reigns
Dread through the dun expanse; save the dull sound
That from the mountain, previous to the storm,
Rolls o’er the muttering earth, disturbs the flood,
And shakes the forest leaf without a breath.
Prone to the lowest vale, the aërial tribes
Descend: the tempest-loving raven scarce
Dares wing the dubious dusk. In rueful gaze
The cattle stand, and on the scowling heavens
Cast a deploring eye, by man forsook,
