was so hard as to resist the blow of a heavy hatchet, the instrument rebounding as if struck upon a rock. The basin, or hollow of the altar, was filled up even full with dry ashes, intermingled with which were some fragments of pottery. * * * Que of the vases, taken in fragments from the mound, has been very nearly restored. The sketch B presents its outlines and the character of its ornaments. Its height is six, and its greatest diameter eight inches * * * Above the deposit of ashes, and covering the entire basin, was a layer of silvery or opaque mica in sheets overlapping each other; and immediately over the center of the basin was heaped a quantity of human bones, probably the amount of a single skeleton, in fragments. The position of these is indicated by O in the section. The layer of mica and calcined bones, it should be remarked to prevent misapprehension, was peculiar to this individual mound, and not found in any other of the class."[1] Calcined bones, however, were found in three out of some twenty mounds of this class examined.[2]
The question now recurs, what was the use of the basin of clay, and what the object of the mound itself I The terms "altars" and "mounds of sacrifice," employed in describing them, imply that human sacrifices were offered on these "altars," "upon which glowed the sacrificial fires."[3] There is no propriety, I respectfully submit, in the use of either of these terms, or in the conclusions they would force us to adopt.
Human sacrifices were unknown in the Lower Status of barbarism; but they were introduced in the Middle Status, when the first organized priesthood, distinguished by their apparel, appears. In parts of Mexico, and, it is claimed, in parts of Central America, these atrocious rites were performed; but they were unknown in New Mexico, and, without better evidence than these miscalled altars afford, they cannot be fastened upon the Mound-Builders. Moreover, these clay beds were not adapted to the barbarous work. Wherever human sacrifices are known to have occurred among the American aborigines, the place was an elevated mound platform, in the nature of a temple, as the Teocalli of Mexico, and the raised altar or sacrificial stone stood before the idol in whose worship the rites were performed. There is neither a temple nor an idol; but a hollow bed of clay
