along its rugged sides. The bottom of the depression was flat and fertile, covered with a luxuriant mass of vegetation. On one side of the base of the gigantic bowl, a cavern struck down into the earth. I stood upon the edge of this funnel-like sink, and marveled at its peculiar appearance. A spirit of curiosity, such as often influences men when an unusual natural scene presents itself, possessed me. I clambered down, swinging from brush to brush, and stepping from shelving-rock to shelving-rock, until I reached the bottom of the hollow, and placing my hand above the black hole in its center, I perceived that a current of cold air was rushing therefrom, upward. I probed with a long stick, but the direction of the opening was tortuous, and would not admit of examination in that manner. I dropped a large pebble-stone into the orifice; the pebble rolled and clanked down, down, and at last, the sound died away in the distance.
"I wish that I could go into the cavity as that stone has done, and find the secrets of this cave," I reflected, the natural love of exploration possessing me as it probably does most men.
My companion above, seated on the brink of the stone wall, replied to my thoughts: "Your wish shall be granted. You have requested that which has already been laid out for you. You will explore where few men have passed before, and will have the privilege of following your destiny into a realm of natural wonders. A fertile field of investigation awaits you, such as will surpass your most vivid imaginings. Come and seat yourself beside me, for it is my duty now to tell you something about the land we are approaching, the cavern fields of Kentucky."
