side by side, the one the other high, a mass of snowy alabaster. Several stalactites in Giant's Hall exceed in length. The Pluto's Ghost, a pillar, is a ghostly white. The cascades are formations like foaming cataracts caught in mid-air and transformed into milk-white or amber alabaster. Brands Cascade is high and wide, and is a wax-like white. Flowstone draperies are abundant throughout the cavern and one of the best examples is Saracen's Tent. The drapery formation can be found in all major rooms and ring like bells when struck heavily by the hand. Their origin and also that of certain so-called scarfs and blankets is from carbonates deposited by water trickling down a sloping and corrugated surface. Sixteen of these alabaster scarfs hang side by side in Hoveys Balcony, three white and fine as crape shawls, thirteen striated like agate with various shades of brown. Streams and true springs are absent, but there are hundreds of basins, some of which are in diameter, and up to in depth. The water in them contains carbonate of lime, which often forms concretions, called pearls, eggs, and snowballs, according to their size. On the fracture these spherical growths are found to be radiated in structure. Calcite crystals line the sides and bottom of water-filled cavities. Variations of level at different periods are marked by rings, ridges and ruffled margins. These are strongly marked about Broaddus Lake and the curved ramparts of the Castles on the Rhine. Here also are polished stalagmites, a rich buff slashed with white, and others, like huge mushrooms, with a velvety coat of red, purple or olive-tinted crystals. In some of the smaller basins it sometimes happens that, when the excess of carbonate acid escapes rapidly, there is formed, besides the crystal bed below, a film above, shot like a sheet of ice across the surface. One pool wide is thus covered so as to show but a third of its surface. The quantity of water in the cavern varies greatly at different seasons. Hence some stalactites have their tips under water long enough to allow tassels of crystals to grow on them, which, in a drier season, are again coated over with stalactitic matter; and thus singular distortions are occasioned. Contiguous stalactites are often inwrapped thus until they assume an almost globular form, through which by making a section the primary tubes appear. Contorted stalactites may be
