Thus I lay for a long time, but afterwards stood up and cried aloud, and shrieked if anyone should haply hear me, calling to Mr. Glennie and Ratsey, and even Elzevir, by name, to save me from this awful place. But there came no answer, except the echo of my own voice sounding hollow and far off down in the vault. So in despair I turned back to the earth wall below the slab, and scrabbled at it with my fingers, till my nails were broken and the blood ran out; having all the while a sure knowledge, like a cord twisted round my head, that no effort of mine could ever dislodge the great stone.
