An hour's hard rowing brought us so near the lighthouse that we almost ceased to apprehend any further danger; but it was suddenly obscured from our view, and at the same time a confused roaring and dashing commenced at a little distance, and rapidly increased in loudness. We soon perceived a tremendous billow rolling towards us. Its top, part of which had already broke, overhung the base, as if unwilling to burst until we were within the reach of its violence. The man who steered the boat brought her head to the sea, but all to no purpose, for the water rushed furiously over us, and we were completely immersed. I felt the boat swept from under me, and was left struggling and groping about in hopeless desperation for something to catch hold of. When nearly exhausted, I received a severe blow on the side from a small cask of water which the sea had forced against me. I immediately twined my arms round it, and, after recovering myself a little, began to look for the boat, and to call to my companions; but I could not discover any vestige of them, or of their vessel. However, I still had a faint hope that they were in existence, and that the intervention of the billows concealed them from my view. I continued to shout as loud as possible, for the sound of my own voice in some measure relieved me from the feeling of awful and heart-chilling loneliness which my situation inspired; but not even an echo responded to my cries, and, convinced that my comrades had all perished, I ceased looking for them, and pushed towards the beacon in the best manner I could. A long series of fatiguing exertions brought me close to the side of the vessel which contained it, and I called out loudly, in hopes that those on board might hear me and come to my assistance; but no one appearing, I waited patiently till a wave raised me on a level with the chains, and then caught hold of them, and succeeded in getting on board.
