John Clare - Fragment

The cataract, whirling down the precipice,
Elbows down rocks and, shouldering, thunders through.
Roars, howls, and stifled murmurs never cease;
Hell and its agonies seem hid below.
Thick rolls the mist, that smokes and falls in dew;
The trees and greenwood wear the deepest green.
Horrible mysteries in the gulph stare through,
Roars of a million tongues, and none knows what they mean.

John Clare
