Eastward, about 40 feet, is the "Jewel Casket." On the way to it are openings to numerous unexplored caves. Affixed to an immense block of limestone are some 30 or 40 shawl-pattern formations of various sizes, which give forth musical sounds when struck with a hard substance, and which, with a little practice, could be played upon like a mammoth harmonicon. _En route_ from the Exhibition to the Jewel Casket, although the passage has not been so dry for twenty years, the rocks are covered with moisture, and the lime can be scraped off like soft soap. From the Exhibition there is a descent eastward of about 100 feet along the gallery, which is somewhat narrow, but the roof of which is covered with pretty stalactites. Near the entrance to the Casket is a remarkable reticulated rock. The descent is by 23 steps east, and then proceeding north about five yards the Jewel Casket is reached. The Jewel Casket is at the end of a very remarkable cave. Its ceiling is marvellously beautiful. The walls and ridges on each side sparkle like gems of the first water. Some of the rocks are covered with virgin white, and some are delicately coloured. The entrance to the Casket itself is very small, being only about 15 inches by 8. Its upper portion is of glistening rich brown, and slopes in varied graceful folds down to the bed rock. When the magnesium light reveals the splendour of the interior it is seen that the Casket stretches away to a considerable distance; the floor is covered with white and amber brilliants and snowy coruscating flakes of dazzling purity. Here are clusters of cave diamonds, opals, and pearls, with delicate fawn-coloured jewels scattered about promiscuously. Rich and rare are the gems this Casket contains, and exclamations of delight are evoked when their charms burst upon the view like a vision of fairyland. Neither tongue nor pen, nor photographic art nor pencil-sketch, can ever do full justice to this natural treasury of beautiful things. JUDGE WINDEYER'S COUCH.
