The next day I resumed my occupation of superintending the Indians. It was, perhaps, the hardest labour I had in that country to look on and see them work, and it was necessary to be with them all the time; for if not watched, they would not work at all.

The next day opened with a drizzling rain, the beginning of the prevailing storm of the country, called El Norte. This storm, we were told, rarely occurred at this season, and the mayoral said that after it was over, the regular dry season would certainly set in. The thermometer fell to fifty-two, and to our feelings the change was much for the better. In fact, we had begun to feel a degree of lassitude, the effect of the excessive heat, and this change restored and reinvigorated us.

This day, too, with the beginning of the storm, Don Simon arrived from Jalacho, according to promise, to pay us a visit. He was not in the habit of visiting Uxmal at this season, and though less fearful than other members of his family, he was not without apprehensions on account of the health of the place. In fact, he had suffered much himself from an illness contracted there. At the hacienda he found the mayoral, who had just returned with me from Jalacho, ill with calentura or fever. This, with the cold and rain of the Norther, did not tend to restore his equanimity. We insisted on his becoming our guest, but agreed to let him off at night on account of the moschetoes. His visit was a fortunate circumstance for us; his knowledge of localities, and his disposition to forward our views, gave us great facilities in our exploration of the ruins, and at the same time our presence and co-operation induced him to satisfy his own curiosity in regard to some things which had not yet been examined.

Throughout the ruins circular holes were found at different places in the ground, opening into chambers underneath, which had never been examined, and the character of which was entirely unknown. We had noticed them, at the time of our former visit, on the platform of the great terrace; and though this platform was now entirely overgrown, and many of them were hidden from sight, in opening a path to communicate with the hacienda we had laid bare two. The mayoral had lately discovered another at some distance outside the wall, so perfect at the mouth, and apparently so deep on sounding it with a stone, that Don Simon wished to explore it.

The next morning he came to the ruins with Indians, ropes, and candles, and we began immediately with one of those on the platform before the Casa del Gobernador. The opening was a circular hole, eighteen inches in diameter. The throat consisted of five layers of stones, a yard deep, to a stratum of solid rock. As it was all dark beneath, before descending, in order to guard against the effects of impure air, we let down a candle, which soon touched bottom. The only way of descending was to tie a rope around the body, and be lowered by the Indians. In this way I was let down, and almost before my head had passed through the hole my feet touched the top of a heap of rubbish, high directly under the hole, and falling off at the sides. Clambering down it, I found myself in a round chamber, so filled with rubbish that I could not stand upright. With a candle in my hand, I crawled all round on my hands and knees. The chamber was in the shape of a dome, and had been coated with plaster, most of which had fallen, and now encumbered the ground. The depth could not be ascertained without clearing out the interior. In groping about I found pieces of broken pottery, and a vase of terra cotta, about one foot in diameter, of good workmanship, and having upon it a coat of enamel, which, though not worn off, had lost some of its brightness. It had three feet, each about an inch high, one of which is broken. In other respects it was entire.

The discovery of this vase was encouraging. Not one of these places had ever been explored. Neither Don Simon nor any of the Indians knew anything about them, and, entering them now for the first time, we were excited by the hope that we had discovered a rich mine of curious and interesting fabrics wrought by the inhabitants of this ruined city. Besides this, we had already ascertained one point in regard to which we were doubtful before. This great terrace was not entirely artificial. The substratum was of natural rock, and showed that advantage had been taken of a natural elevation, so far as it went, and by this means some portion of the immense labour of constructing the terrace had been saved.

On the same terrace, directly at the foot of the steps, was another opening of the same kind, and, on clearing around, we found near by a circular stone about six inches in thickness, which fitted the hole, and no doubt had served as a cover. This hole was filled up with dirt to within two feet of the mouth, and setting some Indians at work to clear it out, we passed on in search of another.

Descending the terrace, and passing behind the high and nameless mound which towers between the Casa del Gobernador and Casa de Palomos, the Indians cleared away some bushes, and brought us to another opening, but a few feet from the path we had cut through, entirely hidden from view until the clearing was made. The mouth was similar to that of the first; the throat about a yard deep, and the Indians lowered me down, without any obstruction, to the bottom.

The Indians looked upon our entering these places as senseless and foolhardy, and, besides imaginary dangers, they talked of snakes, scorpions, and hornets, the last of which, from the experience we had had of them in different parts of the ruins, were really objects of fear; for a swarm of them coming upon a man in such a place, would almost murder him before he could be hauled out.

It did not, however, require much time to explore this vault. It was clear of rubbish, perfect and entire in all its parts, without any symptoms of decay, and to all appearances, after the lapse of unknown years, fit for the uses to which it was originally applied. Like the one on the terrace, it was dome-shaped, and the sides fell in a little toward the bottom, like a well-made haystack. The height was ten feet and six inches directly under the mouth, and it was seventeen feet six inches in diameter. The walls and ceiling were plastered, still in a good state of preservation, and the floor was of hard mortar. Don Simon and Dr. Cabot were lowered down, and we examined every part thoroughly.
