The ruins at this place were not so extensive as we expected to find them. There were but two buildings occupied by the Indians, both in the immediate neighbourhood of our hut, and much ruined, one of which is represented in the plate opposite. A noble alamo tree was growing by its side, and holding it up, which, while I was in another direction, the Indians had begun to cut down, but which, fortunately, I returned in time to save. The building is about 120 feet front, and had two stories, with a grand staircase on the other side, now ruined. The upper story was in a ruinous condition, but parts of it were occupied by Indians. In the afternoon Doctor Cabot and myself set out for a ride to the aguada, induced somewhat by the forest character of the country, and the accounts the Indians gave us of rare birds, which they said were to be found in that direction. The road lay through a noble piece of woods, entirely different from the usual scrubby growth, with thorny and impenetrable underbrush, being the finest forest we had seen, and abounding in sapote and cedar trees. At the distance of half a league a path turned off to the right, overgrown, and hardly distinguishable, following which we reached the aguada. It was a mere hollow basin, overgrown with high grass. We rode down into it, and, dismounting, my first step from the side of my horse carried me into a hole, being a casimba, or pit, made by the Indians for the purpose of receiving the filtrations of water. We discovered others of the same kind, and to save our horses, backed them out to the edge of the aguada, and moved cautiously around it ourselves. These pits were no doubt of modern date, and we could not discover any indications of ancient wells; nevertheless, such may exist, for the aguada has been disused and neglected for an unknown length of time. Soil had accumulated, without removing which, the character and construction of the bottom could not be ascertained. I returned from the aguada in time to assist Mr. Catherwood in taking the plan of the buildings. Our appearance in this wilderness had created astonishment among the Indians. All day, whenever we drew near to the buildings, the women and children ran inside, and now, when they found us entering their habitations, they all ran out of doors. The old major domo, unused to such a commotion among the women, followed us close, anxiously, but respectfully, and without uttering a word; and when we closed the book and told him we had finished, he raised both hands, and, with a relieved expression, exclaimed, "Gracios a Dios, la obra es acabada!" "Thank God, the work is done!" I have nothing to say concerning the history of these ruins. They are the only memorials of a city which, but for them, would be utterly unknown, and I do not find among my notes any memoranda showing how or from whom we first received the intelligence of their existence.
