cond volume, uprose in my mind at this instant, with
fearful distinctness. But then, thought I, what motive can this poor boy
have in alluring me to ruin? What harm have I done him? Plunder surely
cannot be his object, for he was present when I intrusted all I
possessed to the care of the Alcalde of the village. These
considerations left my mind in equal balance, and I turned around to
confront my companion, and draw a decision from the expression of his
countenance.

One look reassured me at once. A playful smile wreathed his lips, and
lightened over his face a gleam of real benevolence, not unmixed, as I
thought, with pity. Hesitating no longer, I preceded him into those
realms of subterranean night. Down, down, down, I trod, until there
seemed no bottom to the echoing cavern. Each moment the air grew
heavier, and our candles began to flicker and grow dimmer, as the
impurities of the confined atmosphere became more and more perceptible.
My head felt lighter, and began to swim. My lungs respired with greater
difficulty, and my knees knocked and jostled, as though faint from
weakness.

Still there seemed no end to the descent. Tramp, tramp, tramp, I heard
the footsteps of my guide behind me, and I vainly explored the darkness
before. At length we reached a broad even platform, covered over with
the peculiar tiling found among these ruins. As soon as Pio reached the
landing-place, he beckoned me to be seated on the stone steps, which I
was but too glad to do. He at once followed my example, and seemed no
less rejoiced than I that the descent had been safely accomplished.

I once descended from the summit of Bunker Hill Monument, and counted
the steps, from the top to the bottom. That number I made 465. The
estimate of the depth of this cavern, made at the time, led me to
believe that it was nearly equal to the height of that column. But there
was no railing by which to cling, and no friend to interrupt my fall, in
case of accident. _Pio was behind me!_

After I became somewhat rested from the fatigue, my curiosity returned
with tenfold force, and I surveyed the apartment with real pleasure. It
was perfectly circular, and was about fifteen feet in diameter, and ten
feet high. The walls seemed to be smooth, except a close, damp coating
of moss, that age and humidity had fastened upon them.

I could perceive no exit, except the one by which we had reached it.

But I was not permitted to remain long in doubt on this po
