Descending the terrace, and passing behind the high and nameless mound which towers between the Casa del Gobernador and Casa de Palomos, the Indians cleared away some bushes, and brought us to another opening, but a few feet from the path we had cut through, entirely hidden from view until the clearing was made. The mouth was similar to that of the first; the throat about a yard deep, and the Indians lowered me down, without any obstruction, to the bottom. The Indians looked upon our entering these places as senseless and foolhardy, and, besides imaginary dangers, they talked of snakes, scorpions, and hornets, the last of which, from the experience we had had of them in different parts of the ruins, were really objects of fear; for a swarm of them coming upon a man in such a place, would almost murder him before he could be hauled out. It did not, however, require much time to explore this vault. It was clear of rubbish, perfect and entire in all its parts, without any symptoms of decay, and to all appearances, after the lapse of unknown years, fit for the uses to which it was originally applied. Like the one on the terrace, it was dome-shaped, and the sides fell in a little toward the bottom, like a well-made haystack. The height was ten feet and six inches directly under the mouth, and it was seventeen feet six inches in diameter. The walls and ceiling were plastered, still in a good state of preservation, and the floor was of hard mortar. Don Simon and Dr. Cabot were lowered down, and we examined every part thoroughly. Leaving this, we went on to a third, which was exactly the same, except that it was a little smaller, being only five yards in diameter.
