This over, we moved on in a body, carrying the iguana, to the next building, which was situated in a different direction, about a quarter of a mile distant, and completely buried in woods. It was seventy-five feet long, and had three doorways, leading to the same number of apartments. A great part of the front had fallen; the plate opposite represents that which remains. With some slight difference in the detail of ornament, the character is the same as in all the other buildings, and the general effect pleasing. Growing on the roof are two maguey plants, Agave Americana, in our latitude called the century plant, but under the hot sun of the tropics blooming every four or five years. There are four species of this plant in Yucatan: the maguey, from which is produced the pulque, a beverage common in all the Mexican provinces, which, taken in excess, produces intoxication; the henneken, which produces the article known in our markets as Sisal hemp; the sabila, with which the Indian women wean children, covering the breast with the leaf, which is very bitter to the taste; and the peta, having leaves twice as large as the last, from which a very fine white hemp is made. These plants, in some or all of their varieties, were found in the neighbourhood of all the ruins, forming around them a pointed and thorny wall, which we were obliged to cut through to reach the buildings. While Mr. C. was engaged in drawing this structure, the Indians told us of two others half a league distant. I selected two of them for guides, and, with the same alacrity which they had shown in everything else, nine volunteered to accompany me. We had a good path nearly all the way, until the Indians pointed out a white object seen indistinctly through the trees, again uttering, with strong gutturals, the familiar sound of "Xlap-pahk," or old walls. In a few minutes they cut a path to it. The building was larger than the last, having the front ornamented in the same way, much fallen, though still presenting an interesting spectacle. As it was not much overgrown, we set to work and cleared it, and left it for another, in regard to which I formed some curious expectations, for the Indians described it as _very new_. It lay on the same path, to the left in returning to the rancho, and separated from us by a great field of taje, through which we were obliged to cut a path for several hundred yards to the foot of the terrace. The walls were entire and very massive; but climbing up it, I found only a small building, consisting of but two apartments, the front much fallen, and the doors filled up, but no sign or token distinguishing it as _newer_ or more modern; and I now learned, what I might have done before by a little asking, that all they meant by their description of it was, that it was the newest known to them, having been discovered but twelve years before, accidentally, on clearing the ground for a milpa, until
