had free ingress, and renewed the water every twelve hours. Here we thoughtlessly. amused ourselves for some time, quoting Acis and Galatea, Diana, and her nymphs, and every classic story applicable to the scene.
At length, the declining sun warned us that it was time to take our departure from the cave, when, at no great distance from us, we saw the back, or dorsal fin of a monstrous shark above the surface of the water, and his whole length visible beneath it. We looked at him and-at each other with dismay, hoping that he would soon take his departure, and go in search of other prey; but the rogue swam to and fro, just like a frigate blockading an enemy's port, and we felt, I suppose, very much as we used to make the French and Dutch feel last war, at Brest and the Texel.
The sentinel paraded before us, about ten or fifteen yards in front of the cave, tack and tack, waiting only to serve one, if not both of us, as we should have served a shrimp or an oyster.
