By long suffering my nerves had been unstrung, until I trembled at the sound of my own voice, and had become in every respect a fitting subject for the species of torture which awaited me.

Shaking in every limb, I groped my way back to the wall; resolving there to perish rather than risk the terrors of the wells, of which my imagination now pictured many in various positions about the dungeon. In other conditions of mind I might have had courage to end my misery at once by a plunge into one of these abysses; but now I was the veriest of cowards. Neither could I forget what I had read of these pits -- that the sudden extinction of life formed no part of their most horrible plan.

Agitation of spirit kept me awake for many long hours; but at length I again slumbered. Upon arousing, I found by my side, as before, a loaf and a pitcher of water. A burning thirst consumed me, and I emptied the vessel at a draught. It must have been drugged; for scarcely had I drunk, before I became irresistibly drowsy. A deep sleep fell upon me -- a sleep like that of death. How long it lasted of course, I know not; but when, once again, I unclosed my eyes, the objects around me were visible. By a wild sulphurous lustre, the origin of which I could not at first determine, I was enabled to see the extent and aspect of the prison.

In its size I had been greatly mistaken. The whole circuit of its walls did not exceed twenty-five yards. For some minutes this fact occasioned me a world of vain trouble; vain indeed! for what could be of less importance, under the terrible circumstances which environed me, then the mere dimensions of my dungeon? But my soul took a wild interest in trifles, and I busied myself in endeavors to account for the error I had committed in my measurement. The truth at length flashed upon me. In my first attempt at exploration I had counted fifty-two paces, up to the period when I fell; I must then have been within a pace or two of the fragment of serge; in fact, I had nearly performed the circuit of the vault.
