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.
