Archæological research in Africa has just begun, and many sources of information in Arabian, Portuguese, and other tongues are not fully at our command; and, too, it must frankly be confessed, racial prejudice against darker peoples is still too strong in so-called civilized centers for judicial appraisement of the peoples of Africa. Much intensive monographic work in history and science is needed to clear mooted points and quiet the controversialist who mistakes present personal desire for scientific proof.
