CAVE See also:KENTUCKY See also:Copyright 1907 by See also:Horace C.Hovey The "See also:short route" requires about four See also:hours, and the "See also:long route " nine. See also:Audubon's See also:Avenue, the one nearest the entrance, is occupied in See also:winter by myriads of bats, that hang from the walls in clusters like swarms of bees. The See also:Gothic Avenue contains numerous large See also:stalactites and stalagmites, and an interesting See also:place called the See also:Chapel, and ends in a See also:double See also:dome and cascade. Among the most surprising features of cave scenery are the See also:vertical shafts that See also:pierce through all levels, from the uppermost galleries, or even from the sink-holes, down to the lowest See also:floor. These are styled pits or domes, according to the position occupied by the observer. A crevice behind a See also:block of See also:stone, 40 ft. long by 20 ft. wide, called the See also:Giant's See also:Coffin, admits the explorer to a place where six pits, varying in See also:depth from 65 ft. to 200 ft., exist in an See also:area of 600 yds. This includes Gorin's Dome, which is viewed from a point midway in its See also:side, and also from its See also:top, the cave. There are some See also:fine stalactites near this See also:pit, and others in the See also:Fairy Grotto and in Pensico Avenue; but, considering the magnitude of Mammoth Cave, its poverty of stalactitic ornamentation is remarkable. The See also:wealth of crystals is, how-ever, surprising, and these are of endless variety and fantastic beauty. See also:Cleveland's See also:Cabinet and See also:Marion's Avenue, each a mile long, are adorned by myriads of See also:gypsum rosettes and curiously See also:twisted crystals, called " oulopholites." Thee cave See also:flowers are unfolded by pressure, as if a sheaf were forced through a tight binding, or the crystal See also:fibres curl outward from the centre of the See also:group. Thus spotless See also:arches of 50 ft. span are embellished by floral clusters and garlands, hiding nearly every See also:foot of the See also:grey See also:limestone. The botryoidal formations See also:hanging by thousands in See also:Mary's Vineyard resemble mimic clusters of grapes, as the oulopholites resemble See also:roses.

Again, there are See also:

chambers with drifts of snowy crystals of the sulphate of See also:magnesia, the ceilings so thickly covered with their efflorescence that a loud concussion will cause them to fall like flakes of See also:snow. Many small rooms and tortuous paths, where nothing of See also:special See also:interest can be found, are avoided as much as possible on the See also:regular routes; but certain disagreeable experiences are inevitable. There is peril also in the vicinity of the deep pits. The one known as the Bottomless Pit was for many years a barrier to all further exploration, but it is now crossed by a wooden See also:bridge. Long before the See also:shaft had been cut as deep as now the See also:water flowed away by a channel gradually contracting to a See also:serpentine way, so extremely narrow as to be called the See also:Fat See also:Man's Misery. The walls, only 18 in. apart, See also:change direction eight times in 105 yds., while the distance from the sandy path to the ledge overhead is but 5 ft. The rocky sides are finely marked with waves and ripples, as if See also:running water had suddenly been petrified. This winding way conducts one to See also:River See also:Hall, beyond which See also:lie the crystalline gardens that have been described. It used to be said that, if this narrow passage were blocked up, See also:escape would be impossible; but an intricate See also:web of fissures, called the Corkscrew, has been discovered, by means of which a See also:good climber, ascending only a few See also:hundred feet, lands loon yds. from the mouth of the cave, and cuts off one or two See also:miles. The See also:waters, entering through numerous domes and pits, and falling, during the See also:rainy See also:season, in cascades of See also:great See also:volume, are finally collected in River Hall, where they See also:form several extensive lakes, or See also:rivers, whose connexion with See also:Green River is known to be in deep springs appearing under arches on its margin. When-ever there is a freshet in Green River the streams in the cave are joined in a continuous See also:body of water, the rise sometimes being 6o ft. above the See also:low-water See also:mark. The subsidence within is less rapid than the rise; and the streams are impassable for about seven months in each See also:year.

They are navigable from May to See also:

October, and furnish interesting features of cave scenery. The first approach is called the Dead See also:Sea, embraced by cliffs 6o ft. high and 100 ft. long, above which a path has been made, whence a See also:stair-way leads down to the See also:banks of the river See also:Styx, a body of water 40 ft. long, crossed by a natural bridge. See also:Lake Lethe comes next—a broad See also:basin enclosed by walls 90 ft. high, below which a narrow path leads to a See also:pontoon at the See also:neck of the lake. A See also:beach of the finest yellow See also:sand extends for 500 yds. to See also:Echo River, the largest of all being from 20 to 200 ft. wide, lo to 40 ft. deep and about three-quarters of a mile long. It is crossed by boats. The arched passage-way is very symmetrical, varying in height from 19 to 35 ft., and famous for its musical reverberations—not a distinct echo, but an harmonious prolongation of See also:sound for from 10 to 30 seconds after the See also:original See also:tone is produced. The long vault has a certain keynote of its own, which, when firmly struck, excites harmonics, including tones of incredible depth and sweetness. There are several other streams here besides those in River Hall. On one of them F. J. See also:Stevenson of See also:London is said to have floated for seven hours without finding its end. A glance at the accompanying See also:map will show that there is a See also:labyrinth of avenues and chasms seldom visited and never fully explored.

New discoveries are frequently made. An exploring party in 1904 found a curious complex of upper and See also:

lower galleries accessible from the most eastern portion of the cave; beyond which another party, in 1905, discovered several large domes previously unknown. H. C. Hovey, in 1907, was led by See also:expert guides into still wilder recesses, where a See also:series of five domes were found, that opened into each other by tall gateways; each dome being 6o ft. in See also:diameter and 175 ft. high. This magnificent group has since been named "Hovey's See also:Cathedral Domes." No instrumental survey of the Mammoth Cave has ever been allowed by the management. The best map possible is therefore only the result of estimates and partial measurements. The depths of the most noted pits have easily been ascertained by See also:line and plummet and the height of several large domes has been found by the use of small balloons. While making a survey exclusively for the cave-owners in 1908, Max Kaemper of See also:Berlin, See also:Germany, See also:MAMUN 533 forced an opening from the See also:main cave into a remarkable region to which the See also:general name of " See also:Violet See also:City " was given, in See also:honour of Mrs Violet See also:Blair See also:Janin, who owned a third of the Mammoth Cave See also:estate. Special features are Kaemper Hall, Blair See also:Castle, the See also:Marble See also:Temple and Walhalla. There are eleven enormous pits, many large fine stalactites and stalagmites and surprisingly beautiful mural decorations. Dr Hovey made and published (1909) a new handbook embodying all known discoveries of importance, with four See also:sketch-maps of the routes of usual See also:exhibition.

The faunaof Mammoth Cave has been classified byF. W.See also:

Putnam, A. S. Packard and E. D. See also:Cope, who have catalogued twenty-eight See also:species truly subterraneous, besides those that may be regarded as stragglers from the See also:surface. They are distributed thus: Verlebrata, 8 species; Insecta, 17; See also:Arachnida, 12; See also:Myriapoda, See also:Crustacea, 5; Vermes, 3; See also:Mollusca, r. See also:Ehrenberg adds a See also:list of 8 Polygastric See also:Infusoria, z fossil infusorian, 5 Phytolitharia and several microscopic See also:fungi. A See also:bed of Agaricus was found by the writer near the river Styx; and upon this hint an See also:attempt has been made to propagate edible fungi in this locality. All the known forms of plant-See also:life are either fungi or allied to them, and many are only microscopic. The most interesting inhabitants of Mammoth Cave are the See also:blind, wingless grasshoppers, with extremely long antennae; blind, colourless See also:crayfish (Cambarus pellucidus, Telk.); and the blind See also:fish, Amblyopsis spelaeus, colourless and viviparous, from 1 in. to 6 in. long. The Cambarus and Amblyopsis have wide See also:distribution, being found in many other caves, and also in deep See also:wells, in Kentucky and See also:Indiana.

Fish not blind are occasionally caught, which are apparently identical with species existing in streams outside. The true subterranean See also:

fauna may be regarded as chiefly of See also:Pleistocene origin; yet certain forms are possibly remnants of See also:Tertiary life.
