The inference that human sacrifices were made here, and the remains afterwards thus collected and deposited, or that a system of burial of this extraordinary character was practised in certain cases, seems to follow legitimately from the facts and circumstances here presented.[103]

That the stratified mounds are not burial places seems sufficiently well established by the fact that the greater number have no traces of human remains upon or around the altars. The suggestion that the various relics found upon these altars were the personal effects of deceased chiefs or priests, thus deposited in accordance with the practice common amongst rude people, of consigning the property of the dead to the tomb with them, is controverted by the fact that p160 the deposits are generally homogeneous. That is to say, instead of finding a large variety of relics, ornaments, weapons, and other articles, such as go to make up the possessions of a barbarian dignitary, we find upon one altar pipes only, upon another a simple mass of galena, while the next one has a quantity of pottery, or a collection of spear heads, or else is destitute of remains except perhaps a thin layer of carbonaceous material. Such could not possibly be the case upon the above hypothesis, for the spear, the arrows, the pipe, and the other implements and personal ornaments of the dead, would then be found in connection with each other. Besides the negative evidence here afforded in support of our classification, it is sustained by the circumstance that these mounds are almost invariably found within enclosures, which, for a variety of concurring reasons, we are induced to believe were sacred in their origin, and devoted primarily, if not exclusively, to religious purposes. The circumstance of stratification, exhibiting as it does an extraordinary care and attention, can hardly be supposed to result from any but superstitious notions. It certainly has no exact analogy in any of the monuments of the globe, of which we possess a knowledge, and its significance is beyond rational conjecture. Why these altars, some of which, as we have already seen, had been used for considerable periods, were finally heaped over, is an embarrassing question, and one to which it is impossible to suggest a satisfactory answer. That all were not covered by mounds is quite certain. The “brick hearths,” of which mention has occasionally been made by writers upon our antiquities, were doubtless none other than uncovered altars. Nothing is more likely than that, even though designed to be subsequently covered, some were left exposed by the builders, and afterwards hidden by natural accumulations, to be again exposed by the invading plough or the recession of the banks of streams. The indentations occasioned by the growth of roots over their surfaces, or the cracks resulting from other causes, would naturally suggest the notion of rude brick hearths. One of these “hearths” was discovered some years since near the town of Marietta in Ohio. It was surrounded by a low bank, of about one hundred feet in circumference, which seemed to have been the ground plan or commencement of a mound.

CHAPTER VII. MOUNDS OF SEPULTURE.

Mounds of this class are very numerous. They are generally of considerable size, varying from six to eighty feet in height, but having an average altitude of from fifteen to twenty or twenty-five feet. They stand without the walls of enclosures, at a distance more or less remote from them. Many are isolated, with no other monuments near them; but they frequently occur in groups, sometimes in close connection with each other, and exhibiting a dependence which was probably not without its meaning. They are destitute of altars, nor do they possess that regularity which characterizes the “temple mounds.” Their usual form is that of a simple cone; sometimes they are elliptical or pear-shaped.
