2. Notice of the Blind Animals which inhabit the Mammoth Cave of Kentucky

Extract

The author commenced with a general sketch of the natural character and condition of the great cave, as it is the peculiarities of their local position which constitute the most remarkable feature in the history of the animals by which it is inhabited. The cave descends through the uppermost rocks of the “Barrens” to those which are nearly or quite upon a level with the Ohio. Though called a cave, it is in fact a series of underground galleries, branching from and inosculating with each other in various directions, the total length of windings being almost incalculable, and even the direct distance from the entrance to the termination extending many miles.
