Across the river I saw another cleft in the cliff-wall which fronted me, with a ledge similar to that on which I stood, but longer. In olden times, I doubt not, some sort of primitive bridge connected the two ledges--possibly before the tunnel was dug beneath the riverbed. Now as I watched, two figures emerged upon that other ledge--one gashed, dust-stained, limping, gripping a bloodstained ax; the other slim, white and girlish.
