This room was found to be forty-eight feet long, the irregular width varied from fourteen to thirty feet and the height from four and one-half to ten feet. The crystal water basin is especially beautiful and the water so clear that we stood looking into it with disappointment, being thirsty and thinking it dry, until the guide laughingly dipped and offered a cupful. The basin is the segment of a circle rounding beneath a massive, overhanging crystal ledge of wonderful beauty, and is nine feet long by two in width. This room and the Stairway into it are alone worthy of a visit, but there is much that is finer still. Out of Gypsy Camp by way of Gunny Sack Crawl, so named by the workmen who spread gunny sacks to relieve the torture of crawling over the beautiful floor of sharp crystals, we enter the first chamber, where active operation is still maintained and certain branches of the great decorative industry of the cave may be carefully studied. This operative chamber, which is unnamed, would no doubt be called a factory in the east, but in its own locality would more likely be referred to as The Works. The next chamber entered is Crystal Flat, whose floor is completely covered with immense crystal blocks, and the wonderful crystal ceiling is exceedingly fine. But time being limited we must pass on into the Lake Room, where is Crystal Lake, the largest body of water in the cave. It is about thirty feet long by fifteen wide and its greatest depth is said to be ten feet. The water is cold and clear, and the gold fish introduced as an experiment three years ago are said to have grown rapidly but not yet turned white, and are not known to have become blind. [Illustration: The Bridal Veil. Page 187.] At some little distance from Crystal Lake, and not within the same range of vision, although in the same room, is Dry Lake, which to the surprise of the guide we found to be not dry, but full of limpid water through which we could distinctly see the delicate clusters of crystals it is depositing. They are of a pale honey yellow and are called Gum-drops on account of the resemblance to that variety of confection.
