The top of this building commanded a grand view, no longer of a dead plain, but of undulating woodlands. Toward the northwest, crowning the highest hill, was a lofty mound, covered with trees, which, to our now practised eyes, it was manifest shrouded a building, either existing or in ruins. The whole intervening space was thick wood and underbrush, and the Indians said the mound was inaccessible. I selected three of the best, and told them that we must reach it; but they really did not know how to make the attempt, and set out on a continuation of the road by which we had reached the ruins, and which led us rather from than to the mound. On the way we met another Indian, who turned back with us, and a little beyond, taking his range, he cut through the woods to another path, following which a short distance, he again struck through the woods, and, all cutting together, we reached the foot of a stony hill covered with the gigantic maguey, or Agave Americana, its long thorny points piercing and tearing all that touched them. Climbing up this hill with great toil, we reached the wall of a terrace, and, climbing this, found ourselves at the foot of the building. It was in a ruinous condition, and did not repay us for the labour; but over the door was a sculptured head with a face of good expression and workmanship. In one of the apartments was a high projection running along the wall; in another a raised platform about a foot high; and on the walls of this apartment was the print of the red hand. The doorway commanded an extensive view of rolling woodland, which, with its livery of deep green, ought to have conveyed a sensation of gladness, but, perhaps from its desolation and stillness, it induced rather a feeling of melancholy. There was but one opening in the forest, being that made by us, disclosing the Casa Grande, with the figures of a few Indians still continuing their clearings on the top. In front of the Casa Grande, at the distance of five hundred yards, and also visible from the top, is another structure, strikingly different from any we had seen, more strange and inexplicable, and having at a distance the appearance of a New-England factory.
