Why these curves were made, I never ascertained, although afterward I gave the subject much attention. We started down the aqueduct at a brisk pace, our candles being frequently extinguished by fresh drafts of air, that struck us at almost every turn. Whenever they occurred, we paused a moment, to reillume them, and then hastened on, as silently and swiftly as before.
After traversing at least five or six miles of this passage, occasionally passing arched chambers like that at the foot of the staircase, we suddenly reached the termination of the aqueduct, which was an apartment the fac-simile of the one at the other end of it. Here also we observed a stone stairway, and my companion at once began the ascent. During our journey through the long arched way behind us, we frequently passed through rents, made possibly by earthquakes, and more than once were compelled to crawl through openings half filled with rubbish, sand and stones. Nor was the road dry in all places. Indeed, generally, the floor was wet, and twice we forded small brooks that ran directly across the path. Behind us, and before, we could distinctly hear the water dripping from the ceiling, and long before we reached the end of the passage, our clothing had been completely saturated. It was, therefore, with great and necessary caution, that I followed my guide up the slippery stairs. Our ascent was not so tedious as our descent had been, nor was the distance apparently more than half so great to the surface. Pio paused a moment at the head of the stairway, extinguished his candle, and then requested me by a gesture to do likewise. When this was accomplished, he touched a spring and the trap-door flew open, upwards. The next instant I found myself standing in a chamber but dimly lighted from above. We soon emerged into open daylight, and there, for the first time since the conquest of Mexico by Cortes, the eyes of a white man rested upon the gigantic ruins of La Casa Grande.
These ruins are far more extensive than any yet explored by travelers in Central America. Hitherto, they have entirely escaped observation. The natives of the country are not even aware of their existence, and it will be many years before they are visited by the curious.
But here they were, a solid reality! Frowning on the surrounding gloom of the forest, and the shadows of approaching night, they stretched out on every side, like the bodies of dead giants slain in battle with the Titans.
Daylight was nearly gone, and it soon became impossible to see anything with distinctness. For the first time, the peculiarity of my lonely situation forced itself upon my attention. I was alone with the Carib boy. I had not even brought my side-arms with me, and I know that it was now too late to make any attempt to escape through the forest. The idea of returning by the subterranean aqueduct never crossed my mind as a possibility; for my nerves flinched at the bare thought of the shrill whistle of Pio, and the mysterious obedience of the stones.
Whilst revolving these unpleasant ideas through my brain, the boy approached me respectfully, opened a small knapsack that I had not before observed he carried, and offered me some food. Hungry and fatigued as I was, I could not eat; the same peculiar smile passed over his features; he rose and left me for a moment, returned, and offered me a gourd of water. After drinking, I felt greatly refreshed, and endeavored to draw my companion into a conversation. But all to no purpose. He soon fell asleep, and I too, ere long, was quietly reposing in the depths of the forest.
It may seem remarkable that the ruins of Casa Grande have never been discovered, as yet, by professional travelers. But it requires only a slight acquaintance with the characteristics of the surrounding country, and a peep into the intricacies of a tropical forest, to dispel at once all wonder on this subject. These ruins are situated about five miles in a westerly direction from those known as El Palacio, and originally constituted a part of the same city. They are as much more grand and extensive than those of El Palacio as those are than the remains at Uxmal, or Copan. In fact, they are gigantic, and reminded me forcibly of the great Temple of Karnak, on the banks of the Nile. But they lie buried in the fastnesses of a tropical forest. One half of them is entombed in a sea of vegetation, and it would require a thousand men more than a whole year to clear away the majestic groves that shoot up like sleepless sentinels from court-yard and corridor, send their fantastic roots into the bedchamber of royalty, and drop their annual foliage upon pavements where princes once played in their infancy, and courtiers knelt in their pride. A thousand vines and parasites are climbing in every direction, over portal and pillar, over corridor and sacrificial shrine. So deeply shrouded in vegetation are these awful memorials of dead dynasties, that a traveler might approach within a few steps of the pyramidal mound, upon which they are built, and yet be totally unaware of their existence. I cannot convey a better idea of the difficulties attending a discovery and explanation of these ruins than to quote what Mr. Stephens has said of El Palacio. "The whole country for miles around is covered by a dense forest of gigantic trees, with a growth of brush and underwood unknown in the wooded deserts of our own country, and impenetrable in any direction, except by cutting away with a machete. What lies buried in that forest it is impossible to say of my own knowledge. Without a guide we might have gone within a hundred feet of all the buildings without discovering one of them."
I awoke with a start and a shudder. Something cold and damp seemed to have touched my forehead, and left a chill that penetrated into my brain. How long I had been asleep, I have no means of ascertaining; but judging from natural instinct, I presume it was near midnight when I awoke. I turned my head toward my companion, and felt some relief on beholding him just where he had fallen asleep. He was breathing heavily, and was completely buried in unconsciousness. When I was fully aroused I felt most strangely. I had never experienced the same sensation but once before in my whole life, and that was whilst in company with Judge E—— on the stone ramparts of Castillo Viejo.
I was lying flat upon my back, with my left hand resting gently on my naked right breast, and my right hand raised perpendicularly from my body. The arm rested on the elbow and was completely paralyzed, or in common parlance, asleep.
