The sun had already sunk behind the line of black volcanic peaks, which look like huge slag-heaps at the mouth of a mine.

True, in Cornwall there would be no slag-cliffs of the Falkenley beneath his feet, as black and blasted at this day as when yon orchard meadow was the mouth of hell, and the south-west wind dashed the great flame against the cinder cliff behind, and forged it into walls of time-defying glass.

These are mining villages we are passing through, and on the horizon are some of those pyramidal slag-heapsthe Fosseswhich have seen some of the fiercest fighting of the war.

Convulsions came; and, where the field Long slept in pastoral green, A goblin-mountain was upheaved (Sure the scared sense was all deceived), Marl-glen and slag-ravine.
