The most of these rooms were plastered, or covered with a fine white cement, some of which was still quite perfect. By washing them, I discovered fresco paintings; but they were much obliterated. The subjects could not be distinguished. On the eastern end of these rooms is a hall running transversely, four feet wide, (having the high angular ceiling,) one side of which is filled with a variety of sculptured work, principally rosettes and borders, with rows of small pilasters; having three square recesses, and a small room on either side. Over the doorways of each are stone lintels three feet square, carved with hieroglyphics both on the front and under side. The western end of these rooms is in almost total ruins. The northern side has a flight of stone steps, but much dilapidated, leading to the top; which, probably, was a look-out place, but is now almost in total ruins. The southern range of rooms is much broken; the outside of which yet shows the elaborate work with which the whole building was finished. I vainly endeavored to find access to the interior of the main building. I discovered two breaches, caused, probably, by the enormous weight of the pile, and in these apertures I made excavations; but could not discover any thing like apartments of any description. It seemed to be one vast body of stone and mortar, kept together by the great solidity of the outer wall, which was built in a masterly manner, of well-formed materials. The angles were finished off with circular blocks of stones, of a large and uniform size. In a northwest direction from the hacienda, of which mention has already been made, are the ruins of a house which, owing, probably, to its having been constructed without any artificial foundation, is still in good preservation. It bears but little resemblance to any of its fellows. It contains eighteen rooms, the largest of which measures eight by twenty-four feet, arranged in double rows, or ante-rooms, and lighted only by a single doorway. They all have the high angular ceilings, like the other buildings, which enclose as much space as the rooms themselves. Those fronting the south are the most remarkable, the inner doorways having each a stone lintel of an unusually large size, measuring thirty-two inches wide, forty-eight long, and twelve deep; having on its inner side a sculptured figure of an Indian in full dress, with cap and feathers, sitting upon a cushioned seat, finely worked; having before him a vase containing flowers, with his right hand extended over it, his left resting upon the side of the cushion—the whole bordered with hieroglyphics. The front part of this lintel contains two rows of hieroglyphics.
