Having provided himself with a box of lucifer matches and a fresh candle, he placed the same implements in my possession, and started in advance. I obeyed almost instinctively.
We passed into the innermost apartments of El Palacio, and approached a cavernous opening into which Mr. Stephens had descended, and which he supposed had been used as a tomb.
It was scarcely high enough in the pitch to enable me to stand erect, and I felt a cool damp breeze pass over my brow, such as we sometimes encounter upon entering a vault.
Pio stopped and deliberately lighted his candle and beckoned me to do the same. As soon as this was effected, he advanced into the darkest corner of the dungeon, and stooping with his mouth to the floor, gave a long, shrill whistle. The next moment, one of the paving-stones was raised from within, and I beheld an almost perpendicular stone staircase leading down still deeper under ground. Calling me to his side, he pointed to the entrance and made a gesture for me to descend. My feelings at this moment may be better imagined than described. My memory ran back to the information given me by the Alcalde, that Pio was a Carib, and I felt confident that he had confederates close at hand. The Caribs, I well know, had never been christianized nor subdued, but roved about the adjacent swamps and fastnesses in their aboriginal state. I had frequently read of terrible massacres perpetrated by them, and the dreadful fate of William Beanham, so thrillingly told by Mr. Stephens in his second 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 point; for Pio soon rose, walked to the side of the chamber exactly opposite the stairs, whistled shrilly, as before, and an aperture immediately manifested itself, large enough to admit the body of a man! Through this he crawled, and beckoned me to follow. No sooner had I crept through the wall, than the stone dropped from above, and closed the orifice completely. I now found myself standing erect in what appeared to be a subterranean aqueduct. It was precisely of the same size, with a flat, cemented floor, shelving sides, and circular, or rather Aztec-arched roof. The passage was not straight, but wound about with frequent turnings as far as we pursued it.
