A terrible abyss is known as the Bottomless Pit, the depths of which have never been sounded. On one of its sides rises a huge crystallisation in the form of a spinning chair, which gleams out from the surrounding blackness, and is called the Devil's Chair. This appalling chasm is credited with various terrible tales. One is of two young lovers who hid in the Mammoth Cave, but finding themselves pursued, tied themselves together with the girl's girdle, and jumped into the abyss. However misguided and foolish we may think these young folk, we can have nothing but pity for two runaway slaves from Alabama, who, after horrible sufferings and privations in the swamps and forests, hoped to have found a resting-place in the great cavern. Alas for their hopes! before long they heard the voices of their pursuers, the cracking of their heavy whips, the baying of the bloodhounds which had tracked them to their refuge. Further and further they retreated in the darkness, only to hear the dreadful sounds draw nearer and nearer, until they found that they could go no further, as they had arrived at a small rocky platform overhanging the Bottomless Pit. Before was certain death, though it was hidden in the horrors of mystery and darkness; behind were the terrors of a death of protracted agony, as a warning to other fugitive slaves! One second's hesitation, and then, as their captors reached out to seize their prey, the despairing men leapt from the rock into the awful pit.
One very singular cave is known as the Church, and is curiously like the crypt of an English Cathedral, such as Gloucester or Canterbury. It is very nearly the same size as the latter. Here stalactites and stalagmites of colossal size have joined to form pillars, united by Norman arches, with wonderful effect. Religious services have often been held in this veritable 'temple not made with hands.'
Indian mummies have been met with in parts of the cavern, proving that it was known to native tribes in past ages. The skeleton of a mastodon, an extinct form of elephant, stands in one of the great halls, and a few live creatures still inhabit the gloomy depths. A cave-rat as large as a rabbit was caught, which, although it had very bright eyes, was quite blind when taken from the cave; but after a month's experience of daylight it gradually began to make use of its eyes. Various kinds of eyeless fish and crabs live in the dark waters, and a live frog was seen wearing an unhappy expression of countenance.
The slow rate at which stalagmites grow has been tested in this cavern by a lantern which was dropped in 1812 and found cemented to the floor in 1843, since which its upward progress has been carefully watched. The Mammoth Cave contains immense quantities of nitre. During the great American Civil War, most of that used was found here, and as gunpowder contains two-thirds of nitre to all its other ingredients, these caverns were of great value to the nation. The Mammoth Cave is now private property, belonging to Dr. John Crogan, who gave ten thousand dollars for it.
