MAMMOTH CAVE , a cave in Edmondson county, Kentucky, U.S.A., 370 14' N. lat. and 86 12' W. long., by rail 85 M. S,S.W. of Louisville. Steamboats run from the mouth of the Green river, near Evansville, Indiana, to the Mammoth Cave landing, The cave is usually said to have been discovered, in 1809, by a hunter named Hutchins; but the county records, as early as 2797, fixed its entrance as the landmark for a piece of real estate. Its mouth is in a forest ravine, 194 ft. above Green river and 600 ft. above the sea. This aperture is not the original mouth, the latter being a chasm a quarter of a mile north of it, and leading into what is known as Dixon's cave. The two portions are not now connected, though persons in one can make themselves heard by those in the other. The cavernous limestone of Kentucky covers an area of 8000 sq. m., is massive and homogeneous, and belongs to the Subcarboniferous period. It shows few traces of dynamic disturbance, but has been carved, mainly by erosion since the Miocene epoch, into many caverns, of which the Mammoth Cave is the largest. The natural arch that admits one to Mammoth Cave has a span of 70 ft., and from a ledge above it a cascade leaps 59 ft. to the rocks below, where it disappears. A flight of stone steps leads the way down to a narrow passage; through which the air rushes with vio lence, outward in summer and inward in winter. The temperature of the cave is uniformly 54 F. through-out the year, and the atmosphere is both chemically and optically of singular purity. While the lower levels are moist from the large pools and rivers that have secret connexion with Green river, the upper galleries are extremely dry. These conditions led at one time to the erection of thirteen cottages at a point about 1 m. underground, for the use of invalids, especially consumptives. The experiment failed, and only two cottages now remain as curiosities.The Main Cave, from 40 to 300 ft. wide and from 35 to 125 ft. high, has several vast rooms, e.g. the Rotunda, where are the ruins of the old saltpetre works; the Star Chamber, where the protrusion of white crystals through a coating of the black oxide of manganese creates an optical illusion of great beauty; the Chief
caries
(From Tilesius.) Rotunda; but few other bones of any description have been found. The so-called Mammoth Cave " mummies " (i.e. bodies kept by being inhumed in nitrous earth), with accompanying utensils, ornaments, braided sandals and other relics, were found in Short and Salt Caves near by, and removed to Mammoth Cave for exhibition. The Main Cave, which abruptly ends 4 M. from the entrance, is joined by winding passages, with spacious galleries on different levels; and, although the diameter of the area of the whole cavern is less than xo m., the conbined length of all accessible avenues is supposed to be about 150 M. The chief
interest
Dome , at the termination of Spark's Avenue, where a cataract falls from a height of 150 ft. amid walls wonderfully draped with stalactitic tapestry. The Egyptian Temple, which is a continuation of the Mammoth Dome , contains six massive columns, two of them quite perfect and 8o ft. high and 25 ft. in diameter. The combined length of these contiguous chambers is 400 ft. By a crevice above they are connected with an arm of Audubon's Avenue. Lucy's Dome, one of the group of Jessup Domes, is supposed to be the loftiest of all these vertical shafts. A pit called the" Maelstrom," in Croghan's Hall
