Where the rock has been cut to make the passage wide enough, the steps are wet, and there is a little basin always full of bright water of a bluish tint. A false step here might precipitate a sight-seer into an almost perpendicular hole, some idea of the depth of which may be formed by casting a stone down, and listening to its striking against the sides, until after the lapse of several seconds the sound of its contact with the floor rises like a feeble voice, still further subdued by distance. Descending five steps, a good sight is obtained of the Grotto Cave. It is 25 feet high in places, and about 10 feet wide, with passages in all directions. It runs south-south-east and north-north-west, and is full of interesting vaults and crypts, over which Nature seems to have cast a mystic spell. For alluring charms, fantastic combinations, and disposition of matter, no comparison can be found between it and the most artistic grottoes built by human hands. One grotto is roofed with delicately white and richly-traced formation, studded with stalactites of rare splendour. Here is a delicate white shaft piercing the dome; there a stalagmite within half-an-inch of the stalactite above. A broken pillar suggests either an accident or a barbaric act; near to it is a perfect column, which, in the dim light, seems like a figure emerging from the cave. Close inspection reveals imitations of coral and seaweed, curved stalactites, and filagree work of the most intricate design. Little flakes of lime, like snow, at the back of the grotto, sparkle like twinkling stars. Another grotto, in the centre of the cave, is made entirely by large stalactites, set off with small ones. Some are covered with filaments about the thickness of ordinary sewing-cotton; others seem as though they were covered with beautiful mosses. Many of the pendants are richly wrought and extremely graceful. The upper stalactites are covered with thicker filaments like twine and pack-thread. A third grotto is remarkable chiefly for a splendid cornice or buttress projecting from a pillar. It is as grand, though not as ornate, as similar formation in the Margherita Cave. It was named on the 10th March 1881, and its designation is appropriate.
