I gazed above me, feeling all the wretchedness of a dying man who, with faculties intact, might stand on the dark edge of the hillside of eternity, glancing back into the bright world; and that small opening far, far overhead, seemed as the gate to Paradise Lost. Many a person, assured of ascending at will, has stood at the bottom of a deep well or shaft to a mine, and even then felt the undescribable sensation of dread, often terror, that is produced by such a situation. Awe, mystery, uncertainty of life and future superadded, may express my sensation. I trembled, shrinking in horror from my captor and struggled violently. "Hold, hold," I begged, as one involuntarily prays a surgeon to delay the incision of the amputating knife, "just one moment." My companion, unheeding, moved on, the light vanished instantly, and we were surrounded by total darkness. God's sunshine was blotted out. [Illustration: "THIS STRUGGLING RAY OF SUNLIGHT IS TO BE YOUR LAST FOR YEARS."] Then I again became unconcerned; I was not now responsible for my own existence, and the feeling that I experienced when a prisoner in the closed carriage returned. I grew careless as to my fate, and with stolid indifference struggled onward as we progressed slowly against the current of water. I began to interest myself in speculations regarding our surroundings, and the object or outcome of our journey. In places the water was shallow, scarce reaching to our ankles; again it was so deep that we could wade only with exertion, and at times the passage up which we toiled was so narrow, that it would scarcely admit us. After a long, laborious stemming of the unseen brook, my companion directed me to close my mouth, hold my nostrils with my fingers, and stoop; almost diving with me beneath the water, he drew me through the submerged crevice, and we ascended into an open chamber, and left the creek behind us. I fancied that we were in a large room, and as I shouted aloud to test my hypothesis, echo after echo answered, until at last the cry reverberated and died away in distant murmurs. We were evidently in a great pocket or cavern, through which my guide now walked rapidly; indeed, he passed along with unerring footsteps, as certain of his course as I might be on familiar ground in full daylight. I perceived that he systematically evaded inequalities that I could not anticipate nor see. He would tell me to step up or down, as the surroundings required, and we ascended or descended accordingly. Our path turned to the right or the left from time to time, but my eyeless guide passed through what were evidently the most tortuous windings without a mishap. I wondered much at this gift of knowledge, and at last overcame my reserve sufficiently to ask how we could thus unerringly proceed in utter darkness. The reply was: "The path is plainly visible to me; I see as clearly in pitch darkness as you can in sunshine." "Explain yourself further," I requested.
