The large walls of silex tottered and fell upon the sand, and the sand itself, an instrument of pain when launched from its hard bed, riddled the faces with its myriad cutting atoms. Nor had those antagonistic forces been dormant, which are always at work wearing down the surface of the land; the great piles of strata had been intersected by many wide valleys, and the trees now changed into silex, were exposed projecting from the volcanic soil, now changed into rock, whence formerly, in a green and budding state, they had raised their lofty heads. |
