I had twice penetrated as far as this place, at the earlier period of my sojourn in the fishing-hamlet, and while I now listened to the thunder-sound, I knew from what cause it proceeded.
Beyond the spot where I stood, the rocks descended suddenly, and almost perpendicularly, to the range below them. In one of the highest parts of the wall-side of granite thus formed, there opened a black, yawning hole that slanted nearly straight downwards, like a tunnel, to unknown and unfathomable depths below, into which the waves found entrance through some subterranean channel. Even at calm times the sea was never silent in this frightful abyss, but on stormy days its fury was terrific. The wild waves boiled and thundered in their imprisonment, till they seemed to convulse the solid cliff about them, like an earthquake. But, high as they leapt up in the rocky walls of the chasm, they never leapt into sight from above. Nothing but clouds of spray indicated to the eye, what must be the horrible tumult of the raging waters below.
With my recognition of the place to which I had now wandered, came remembrance of the dangers I had left behind me on the rock-track that led from the mainland to the promontory—dangers of narrow ledges and treacherous precipices, which I had passed safely, while unconscious of them in the mist, but which I shrank from tempting again, now that I recollected them, until the sky had cleared, and I could see my way well before me. The atmosphere was still brightening slowly over the tossing, distant waves: I determined to wait until it had lost all its obscurity, before I ventured to retrace my steps.
