On the top is a structure which, at a distance, as seen indistinctly through the trees, had the appearance of a second story, and, as we approached, it reminded us of the towering structures on the top of some of the ruined buildings at Palenque.

The access to this structure was by no means easy. There was no staircase or other visible means of communication, either within or without the building, but in the rear the wall and roof had fallen, and made in some places high mounds reaching nearly to the top. Climbing up these tottering fabrics was not free from danger. Parts which appeared substantial had not the security of buildings constructed according to true principles of art; at times it was impossible to discover the supporting power, and the disorderly masses seemed held up by an invisible hand. While we were clearing off the trees upon the roof, a shower came up suddenly, and, as we were hurrying to descend and take refuge in one of the apartments below, a stone on the edge of the cornice gave way and carried me down with it. By great good fortune, underneath was a mound of ruins which reached nearly to the roof and saved me from a fall that would have been most serious, if not fatal, in its consequences. The expression on the face of an Indian attendant as he saw me going was probably a faint reflection of my own.

The structure on the top of this building is about fifteen feet high and four feet thick, and extends over the back wall of the front range of apartments, the whole length of the edifice. In many places it has fallen, but we were now more struck than when at a distance with its general resemblance to the ruined structures on the top of some of the buildings at Palenque. The latter were stuccoed; this was of cut stone, and more chaste and simple. It could not have been intended for any use as part of the edifice; the only purpose we could ascribe to it was that of ornament, as it improved the appearance of the building seen from a distance, and set it off with great effect on near approach.

I have said that we were somewhat excited by the first view of the façade of this building. Ascending the steps and standing in the doorway of the centre apartment, we broke out into an exclamation of surprise and admiration. At Uxmal there was no variety; the interiors of all the apartments were the same. Here we were presented with a scene entirely new. The plate opposite represents the interior of this apartment. It consists of two parallel chambers, the one in front being twenty-seven feet long and ten feet six inches wide, and the other of the same length, but a few inches narrower, communicating by a door in the centre. The inner room is raised two feet eight inches higher than the front, and the ascent is by two stone steps carved out of a single block of stone, the lower one being in the form of a scroll. The sides of the steps are ornamented with sculpture, as is also the wall under the doorway. The whole design is graceful and pretty, and, as a mere matter of taste, the effect is extremely good. Here, on the first day of our arrival, we spread out our provisions, and ate to the memory of the former tenant. His own domains could not furnish us with water, and we were supplied from the wells of Nohcacab.

In the engraving but one doorway appears on each side of the centre, the front wall at the two ends having fallen. On both sides of this centre doorway were two other doorways opening into apartments. Each apartment contains two chambers, with the back one raised, but there are no steps, and the only ornament is a row of small pilasters about two feet high under the door, and running the whole length of the room.

Such is a brief description of the façade and front apartments, and these formed not more than one third of the building. At the rear and under the same roof were two ranges of apartments of the same dimensions with those just described, and having a rectangular area in front. The whole edifice formed nearly a square, and though having less front, with a great solid mass nearly as thick as one of the corridors, for the centre wall, it covered nearly as many square feet as the Casa del Gobernador, and probably, from its lavishness of ornament, contained more sculptured stone. The rest of the building, however, was in a much more ruinous condition than that presented. At both ends the wall had fallen, and the whole of the other front, with the roof, and the ruins filled up the apartments so that it was extremely difficult to make out the plan.

The whole of the terrace on this latter side is overgrown with trees, some of which have taken root among the fragments, and are growing out of the interior of the chambers.

The sketch opposite will give some idea of the manner in which the rankness of tropical vegetation is hurrying to destruction these interesting remains. The tree is called the alamo, or elm, the leaves of which, with those of the ramon, form in that country the principal fodder for horses. Springing up beside the front wall, its fibres crept into cracks and crevices, and became shoots and branches, which, as the trunk rose, in struggling to rise with it, unsettled and overturned the wall, and still grew, carrying up large stones fast locked in their embraces, which they now hold aloft in the air. At the same time, its roots have girded the foundation wall, and form the only support of what is left. The great branches overshadowing the whole cannot be exhibited in the plate, and no sketch can convey a true idea of the ruthless gripe in which these gnarled and twisted roots encircle sculptured stones.
