to the success of our expedition. Our guide, however, peering from side to side, seemed confident as to his whereabouts, as well as to that of the “piedras,” and in half an hour we came to the spot where they had existed. I say had existed, for although the ground was strewn with fragments, but a single figure, “IDOL FROM SUBTIABA, NO. 4,” remained entire. It stood as shown in the accompanying plate, partially buried in the earth. Its height above the ground was six feet four inches; the material, sand-stone. As in the other instances, the face had been mutilated, but the remainder of the figure was nearly perfect. The hair seemed to be thrown back from the forehead in rolls; or perhaps what I have supposed to be the hair is a modified example of that kind of ornamental featherwork so common in the ancient monuments of Mexico, Yucatan, and Central America. A broad collar passes around the neck, and a circular plate, or shield, with an attempt at a representation of a human face in the centre, is suspended from it, in front of the figure. A kind of belt passes around the body, above the hips, from which depends a flap, like that frequently worn by the Indians of the frontiers, even to this day. At the lower extremity of this is a round, cup-shaped hole, capable of containing about a quart, the purposes of which are not apparent. In cutting paths around this figure, I came upon an oblong elevation of stones, which seemed to have been the base of some edifice, or one of the ancient teocallis or altars of the aborigines. It was about two hundred feet long, sixty broad, and ten high. Around the edges the stones still retained some degree of regularity, but the whole was nevertheless a ruin, and large trees were growing on its summit. The numerous fragments of sculpture scattered around this spot showed conclusively that it had been visited by systematic violence, not only anciently, at the period of the Conquest, but subsequently, and within a very few years. My guide told me that he could remember the time when the Indians came here secretly by night, and performed strange dances around these idols, and poured out libations before them. The ground around the single erect figure above described was comparatively free from undergrowth, showing that even now it is secretly visited, by the descendants of the people who first erected it, for the performance of traditionary, sacred ceremonies. The priests are vigilant in detecting and putting down these remnants of idolatry; and only a few months before my arrival had broken up a remarkable figure of an animal called “El Toro,” the bull, which existed about a league distant from this very spot, and to which the Indians, for a long time, openly resorted, to make offerings of _tiste_, and to perform dances preparatory to putting their crops in the ground. The destruction of the idol was effected secretly, and afterwards proclaimed to have been done by the lightnings
