that when viewed from the stairway appears to rest solidly against the most distant wall, and looks so small an object in that vast space as to render a realization of its actual measurement impossible. The height of the Throne is sixty-five feet and the girth two hundred. It is a mass of dripstone resting on a limestone base reserved from the ancient excavation to receive it, and on careful inspection the perpendicular lines, observed on the front, are found to be a set of rather large organ pipes. A fresh fracture shows the Throne to be a most beautiful white and gold onyx. The outer surface has now received a thin coating of yellow clay which was, of course, regretted, but later observations on onyx building reveals the pleasing fact that if the crystal-bearing waters continue to drip, the yellow clay will supply the coloring matter for a golden band of crystal.
The Throne is hollow and has a natural opening in one side by which it may be entered, but the space within is too limited to invite a lengthy stay. That portion of the outside which is nearest the wall is formed with sufficient irregularity of outline to admit of an ascent to the top, and the view obtained is well worth the difficult scramble up and the apprehensive slide down. Being raised so high above all objects that divide attention or in some degree obstruct the view, permits a freedom of outlook that sensibly increases the appreciation of the vastness of the enclosed chamber and its enclosing walls. Efforts to establish the age of the deposit by observations on the yearly growth, would afford little satisfaction, for the obvious reason that conditions governing the growth are dependent, in a measure, on each season's vegetation. Deposit began, of course, after the erosion of the chamber ceased, and therefore represents only a fraction of the age of the cave itself. About thirty feet west of the White Throne and against the wall, stands the next onyx attraction in the form of a beautiful fluted column nearly twenty feet high, tapering up from a base three feet in diameter, and known as the Spring Room Sentinel, because the Spring of Youth is just behind it although not directly connected with the Auditorium; it being the first chamber on the left in Total Depravity Passage, a wet and dangerous way of which next to nothing is known, but the entrance to which is a fine arch a few feet west of the Sentinel. The Spring of Youth is reached by climbing through a window-like opening, and is very small, very wet, very cold, and very beautiful. It is not more than ten feet high nor six in its greatest length and breadth, but every inch of its irregular surface is composed of dripstone of a bright yellowish-red and colorless crystal; and down the glittering walls trickles clear and almost ice-cold water, to the onyx floor where it is caught and held in a marvelous fluted bowl of its own manufacture. This is said to be the gem of the whole cave and seems to have been placed where it is for the consolation of those who are unable to enjoy the peculiar grandeur of the Auditorium, and leave it as some actually are said to do, with a sense of disappointment, because it is not the gleaming white hall of marble which some writers for reputable journals have allowed their imaginations to create.
In winter the Spring of Youth Room takes on a complete coating of ice, with icicles of all sizes hanging from the ceiling and projections. The effect is described as being wonderfully beautiful.
Further down Total Depravity Passage we were not urged to go, because at that season of the year it is wet and difficult, without any sufficient promise of a brilliant compensation for the achievement of such a journey. But the Spring of Youth Room, or as it is generally called, the Spring Room, is more than ample justification for the existence of the passage, and would still be if that passage were several miles in length and the attraction located at the most distant limit.

The various passages in Marble Cave are by no means alike or even similar; some having been opened by the action of water assisted only by acid carried in solution; while others are the unmistakable crevices of earthquake origin, afterwards enlarged, or perhaps only remodeled, as we might say, by the water's untiring energy in changing the position of rock masses without obliterating evidences of original design.
A glance at the map shows the sudden breaking off of the various passages represented; the end, however, is not of the passages themselves, but only of the exploration or the
