There are circumstances with respect to the manner of burial by the Mound Builders which require to be noticed. It seems from the evidence of the various excavations that have been made, that it was frequently the custom to construct in the centre of the spot intended to be a burial place, a vault surrounded by upright logs of wood. In this was put the earliest burial, which was probably that of a chief. This vault was then covered with a roof of logs, and over it was piled a heap of stones. Other mounds were added in the course of time, and were placed on the surface of the ground in a circle surrounding the vault. This system of placing mounds was then continued in circles, one outside the other, until the space or area intended to be occupied was filled up. The later interments were probably made successively one above the other, until the tumulus was completed. The time that would elapse before a tribe had raised such a high mound as that at the Grave Creek, would necessarily be very long. In the town of Newark, situated in a part of the country which appears to have been much occupied by the races that built the ancient earthworks, a very interesting collection of local antiquities had been brought together. Amongst the various relics discovered in the mounds were, stone axes and chisels, quantities of rude coarse pottery, many shell beads, and some copper bracelets. Dr. Wilson, who was a resident in the neighbourhood, and took much personal interest in antiquarian investigations, told me he had observed that the larger burial places seemed to have been raised gradually, and at intervals. He had formed the opinion that the Indians usually traced upon the surface of the ground the outer base of the tumulus. Within the inclosed space a number of skeletons were then laid and covered over with layers of earth or small mounds. Over these, after a certain time had elapsed, more skeletons were placed and similarly covered. This system of burial was continued until the mound was completed. There were evidences of a great burning having taken place upon the top of every successive series of burials. The nature of the contents of such of the smaller mounds as had been opened varied in many respects. In some instances nothing was found except ashes and broken pottery. In others were skeletons together with stone pipes, chisels made of hard greenstone, flint arrow heads, bone awls and numerous beads. There were also occasionally found a few rudely made copper rings. In a mound which was supposed to be a child’s grave, a necklace of beads, strung upon a kind of fibre, was placed round the neck of the skeleton.
