As from some mountain's craggy forehead torn,
A rock's round fragment flies, with fury borne,
(Which from the stubborn stone a torrent rends,)
Precipitate the ponderous mass descends:
From steep to steep the rolling ruin bounds;
At every shock the crackling wood resounds;
Still gathering force, it smokes; and urged amain,
Whirls, leaps, and           down, impetuous to the plain:
There stops--so Hector.
