We walked as far as the curious hollow in the earth called "The Devil's Frying-pan."  It is like a vast crater, two acres in extent, two hundred feet deep, and converging to an orifice at the bottom, some sixty feet in diameter.  Round the upper edge we observed furze, gorse, and a variety of grasses growing in great profusion, but below was the bare rock.  Carefully creeping down, we noticed through the hole the shine of the water in the cavern beneath.  We were wondering how this curious aperture could have been formed, when papa explained that the ground was once level, but that there had been a cavern below it, which was gradually increased by the roof crumbling away, and the _debris_ being washed out by the sea, until the rock became too thin to bear the superincumbent weight of earth, when the centre gave way, and sinking down, the surrounding earth followed, until it was formed into its present shape.  The sea continually rushing in, again cleared out the cavern.  As we were anxious to look up it, we hurried back to the boat, and the tide being suitable, we pulled in, and were able to look up through the hole down which we had before gazed.
