Contiguous to this front are two irregular buildings, as represented in the plan. The one on the right, situated some twenty-five feet from it, (about two feet off the right line,) has a front of about thirty-five feet, its sides ten wide, and its height twenty feet, containing one room similar in its finish to those before described. The front of this building is elaborately sculptured with rosettes and borders, and ornamental lines; the rear is formed of finely cut stone, now much broken. Near by are numerous heaps of hewn and broken stones, sculptured work and pillars. [Illustration: Decoration] The other building on the left, is about eight feet from the principal front, measuring twenty-two feet in length, thirteen in width, and thirty-six in height. The top is quite broken, and has the appearance of having been much higher. The _agave Americana_ was growing thriftily upon its level roof. On all sides of this building are carved figures, broken images, in sitting postures; rosettes and ornamental borders, laid off in compartments; each compartment having three carved hooks on each side and angle. This building contains but one room, similar to that on the right. A soil has collected on the tops or roofs of these structures to the depth of three or four feet, in which trees and other vegetation are flourishing. From these portions of the ruins I worked my way through the wild thicket, by which they are surrounded, to the north side of the main building, in the centre of which I found a flight of small stone steps, overgrown with bushes and vines, which I cut away, and made an ascent by pulling myself up to the summit, a distance of forty feet. This platform is an oblong square, one hundred by seventy-five feet. Here a range of rooms were found, occupying about two-thirds of the area; the residue of the space probably formed a promenade, which is now filled up with crumbling ruins, covered with trees and grass. These rooms varied in size; the smallest of which measured six by ten, and the largest six by twenty-two feet.
