About an hour before dark, and a league before reaching the village of Opocheque, I saw on the left, near the road, a high mound, with an edifice on its top, which at that distance, as seen through the trees, seemed almost entire. It stood in a corn-field. I was not looking out for anything of the kind, and but for the clearing made for the milpa, I could not have seen it at all. I threw the bridle of my horse to the major domo, and made for it, but it was not very easy of access. The field, according to the fashion of the country, was enclosed by a fence, which consisted of all the brush and briers collected on the clearing, six or eight feet high and as many wide, affording a sufficient barrier against wild cattle. In attempting to cross this, I broke through, sinking almost to my neck in the middle, and was considerably torn by thorns before I got over into the milpa. The mound stood on one side of the milpa, isolated, and of the building upon it, the lower part, to the cornice, was standing. Above the cornice the outer wall had fallen, but the roof remained, and within all was entire. There was no view from the top; beyond the milpa all was forest, and what lay buried in it I had no means of ascertaining. The place was silent and desolate; there was no one of whom I could ask any questions. I never heard of these ruins till I saw them from the back of my horse, and I could never learn by what name they are called. At half past six we reached the village of Opocheque. In the centre of the plaza was a large fountain, at which women were drawing water, and on one side was a Mestizo family, with two men playing the guitar. We stopped for a cup of water, and then, pushing on by a bright moonlight, at nine o'clock reached the village of Moona, which the reader of my former volumes may remember was the first stage of our journey on leaving Uxmal for home. Early the next morning we resumed our course. Immediately behind the village we crossed the sierra, the same broken and stony range, commanding on both sides the same grand view of a boundless wooded plain. In an hour we saw at a distance on our left the high mound of ruins visible from the House of the Dwarf, known under the Indian name of Xcoch. About five miles before arriving at Uxmal, I saw on the right another high mound. The intervening space was covered with trees and thorn-bushes, but I reached it without dismounting. On the top were two buildings about eighteen feet each, with the upper part of the outer walls fallen. Of both, the inner part was entire. At twelve o'clock I reached Uxmal. The extent of my journey had been thirteen leagues, or thirty-nine miles; for though I had varied my route in returning, I had not increased the distance, and I had seen seven different places of ruins, memorials of cities which had been and had passed away, and such memorials as no cities built by the Spaniards in that country would present.
