beautiful objects, lose by contrast with these ornaments, and dwindle into mere clumsy, awkward icicles. Besides these, there are tufts of 'hair salt,' native sulphate of magnesia, depending like adhering snowballs from the roof, and periodically detaching themselves by their own increasing weight. Indeed, the more solid alabaster ornaments become at last overgrown, and fall upon the floor of the grotto, which was found covered with numbers quite entire, besides fragments of others broken by the fall." A distinguished geologist has said that he believed Cleveland's Avenue, two miles in length, contained a petrified form of every vegetable production on earth. If this be too large a statement, it is at least safe to say that its variety is almost infinite. Amongst its other productions, are large piles of Epsom salts, beautifully crystallized. Travellers have shown such wanton destructiveness in this great temple of Nature--mutilating beautiful columns, knocking off spar, and crushing delicate flowers--that the rules are now very strict. It is allowable to touch nothing, except the ornaments which have loosened and dropped by their own weight. These are often hard enough to bear transportation. After you leave Alma's Bower, the cave again becomes very rugged. Beautiful combinations of gypsum and spar may still be seen occasionally overhead: but all round you rocks and stones are piled up in the wildest manner. Through such scraggy scenery, you come to the Rocky Mountains, an irregular pile of massive rocks, from 100 to 150 feet high. From these you can look down into Dismal Hollow--deep below deep--the most frightful looking place in the whole cave. On the top of the mountain is a beautiful rotunda, called Croghan Hall, in honor of the proprietor. Stalactites surround this in the richest fringe of icicles, and lie scattered about the walls in all shapes, as if arranged for a museum. On one side is a stalagmite formation like a pine-tree, about five feet high, with regular leaves and branches; another is in a pyramidal form, like a cypress. If you wind down the mountains on the side opposite from that which you ascended, you will come to Serena's Arbor, which is thirteen miles from the entrance of the cave, and the end of this avenue. A most beautiful termination it is! In a semicircle of stalactite columns is a fountain of pure water spouting up from a rock. This fluid is as transparent as air; all the earthy particles it ever held in suspension, having been long since precipitated. The stalactite formations in this arbor are remarkably beautiful.
