 of the funnel, we managed to descend to the bottom, which had gradually contracted until it was only a narrow passage slanting down towards, or it might be below, the river-bed. Here we entered upon a perfect labyrinth of fissures, at first so small that we could only creep in one after another on all fours, but increasing till they were frequently ten feet high; they terminated above in mere clefts, from which the water kept dripping, and formed stalactites that were not exceptional in character, either of form or size; they had nearly all been damaged by previous visitors, and the ground was covered with their fragments.

The very multiplicity of the underground passages through which we were conducted, was in itself a proof that the rock had been rifted in all directions, and in many places where the two clefts came into connexion, a sort of vault was formed overhead, somewhat higher than the passages, but presenting no other remarkable feature. The sides were dark grey, generally bare and smooth. The little brook, of which we could hear the sound as soon as we entered, rippled through the caves from east to west, and covered the breadth of the passage, making it necessary for us to perform the best part of our excursion barefooted. As we went onwards, either to the west or north, the water became considerably deeper; we caught sight of some stalactites, glistening and undamaged, just before us, but were prevented from securing them by our guides, who refused to advance a step further.
