scrambling brought me into a vast chamber, the floor of which was piled up with enormous blocks, while the lowest part seemed to offer two possible routes onwards. One of these proved to be a mere hollow, but the other was evidently the channel of a stream, and apparently led onwards into further caves. But the roof was extremely low, and it was quite impossible to wriggle through. One of my companions, who had now joined me, also failed to squeeze through the opening, and we decided to leave it until the hole could be enlarged with pick and shovel. The alleged 300 feet was found by aneroid to be exactly 100 feet. In a corner of this lofty cavern was a steep fissure which seemed to be well worth exploring. The bottom half of it was completely walled in by an enormous flake of Limestone that had come down from the roof, and looked as if a touch would send it tumbling on the heaps of rock at the bottom of the cave. We scrambled up the fissure at the back of this, and reached a promising gallery; but, to our disgust, this was entirely blocked up with clay and mud at the top, and it was impossible to proceed. Gaining the summit of the huge Limestone flake, we lit up the cave with magnesium wire, and were deeply impressed by its height and the grandeur of the shattered crags bristling on walls, roof, and floor. Everything was black, save one long, dripping cascade of stalagmite on the wall over against us; its unsullied whiteness shone weirdly out of the gloom as the fierce light fell on it. Just at that moment voices were heard, and from a rent in the rocky wall in front the intolerable beam of the searchlight came right in our faces. The remainder of the party had followed us up, and reached the spot where we had first looked over into the deep chasm. Revealed in all its extent by this penetrating light, the cave reminded us strongly of the enormous chamber that we had explored a few months earlier in the lowest part of the Blue John Mine in Derbyshire. On the way back one of the acetylene lamps fell down the pit by which we had entered, and was completely smashed. With no other mishap, we made our way through the tortuous passages and amongst the chaos of tumbled rock masses back to the cavern under "Solomon's Temple."
