 it with a gentle wink. We both laughed, and, springing from the rocks together, plunged head first into the sea.

We gained the interior of the submarine cave without difficulty, and, on emerging from the waves, supported ourselves for some time by treading-water, while we held the two bundles above our heads. This we did in order to let our eyes become accustomed to the obscurity. Then, when we could see sufficiently, we swam to a shelving rock, and landed in safety. Having wrung the water from our trousers, and dried ourselves as well as we could under the circumstances, we proceeded to ignite the torch. This we accomplished without difficulty in a few minutes; and no sooner did it flare up than we were struck dumb with the wonderful objects that were revealed to our gaze. The roof of the cavern just above us seemed to be about ten feet high, but grew higher as it receded into the distance, until it was lost in darkness. It seemed to be made of coral, and was supported by massive columns of the same material. Immense icicles (as they appeared to us) hung from it in various places. These, however, were formed, not of ice, but of a species of limestone, which seemed to flow in a liquid form towards the point of each, where it became solid. A good many drops fell, however, to the rock below, and these formed little cones, which rose to meet the points above. Some of them had already met, and thus we saw how the pillars were formed, which at first seemed to us as if they had been placed there by some human architect to support the roof. As we advanced farther in, we saw that the floor was composed of the same material as the pillars; and it presented the curious appearance of ripples, such as are formed on water when gently ruffled by the wind. There were several openings on either
