Beneath the trampling sound of rushing feet
The broad earth sounded hollow: and [270]as rocks
From some high mountain-top precipitate
Leap with a bound, and o’er each other whirl’d
Shock in the dizzying fall: and many an oak
Of lofty branch, pine-tree and poplar deep
Of root are crash’d beneath them, as their course
Rapidly rolls, till now they touch the plain;
So met these foes encountering, and so burst
Their mighty clamour. Echoing loud throughout
