On the other hand, a world-old custom, which may be set down as human and universal, dictated, and among all nomadic peoples continues to dictate, the abandonment of any habitation in which a death has occurred. The obvious motive is expressed in a surviving superstition that a second decease is likely to follow a first. Death, naturally impersonated and identified with the spirit of the departed, will return to the place where he has once made himself at home, and in which he has proprietary rights. This idea constitutes a superstition which stands directly in the way of progress; thus the Navajo refuses to build a house, which at the first mortality among his family it would be necessary to desert. The cause of the general custom is to be sought, not in any sanitary principle, but in the associations explained, acting with superstitious force. In the course of time and with the advance of culture such desertion is no longer possible, and some means must be found by which the requirement shall be evaded; the desired escape is effected by such alterations as shall vary the character of the mansion and indicate it as a new place of abode, not subject to the perils of the home invaded by death. The remarks which have been offered are presented only by way of suggestions which could be indefinitely extended. To construct a commentary on the body of beliefs presented in this volume would be an enticing but a laborious task; such notes, also, would far exceed in volume the compass of this work. Besides, as originally remarked, the present collection contains but a part of the volume of surviving superstitions. For these reasons, it will be possible to proceed no farther. In commending this collection to the attention of psychologists, and to the continuing industry of students of folk-lore, I need only express my hope that it may be sufficient to make clear how far-reaching are the studies for which folk-lore supplies material. The history of religion, the theory of mythologies, cannot afford to overlook modern popular beliefs, in which ancient conceptions appear as still effective. In the same way, archaeology, regarded only as the investigation of monuments and literatures, and dissociated from the observation of continuing human life, is devoid of inspiration and vitality. These studies, when accompanied with disregard of the existing world, and indifference to the fortunes and relations of humanity as a whole, remain not only incomplete, but positively misleading, and devoid of their best claim on respect and attention. It is to be hoped that this interesting collection, made under so many difficulties, will have a useful effect in helping to emphasize this truth, and to render obvious the possible uses of traditional information.
