Cyrus Thomas, The Problem of the Ohio Mounds
“ As the country was inhabited only by Indians at the time of its discovery, and as we have no evidence, unless derived from the mounds, of its having ever been occupied by any other people, every fact indicating a similarity between the arts, customs, and social life of the mound-builders and those of the red Indians, is an evidence of the identity of the two peoples. The greater the number of these resemblances, the greater the probability of the correctness of the theory, so long as we find nothing irreconcilable with it. ”
