and one which is doubtless always a fairly positive indication of a belief in demons such as arises in connection with the impression made by death. The dead person is bound in the position that will best prevent his return. Thus, all these prehistoric remains suggest a culture similar to that of primitive tribes of to-day. But, just because they reveal conditions not essentially different from those of the present, these remains make another important contribution to our knowledge of primitive man. They indicate the great stability of primitive culture in general, and render it probable that, unless there are special conditions making for change, such as migrations and racial fusions, the stability increases in proportion to the antiquity. Though this may at first glance seem surprising, it becomes intelligible when we consider that isolation from his surroundings is an important characteristic of primitive man. Having very little contact with other peoples, he is in no wise impelled to change the modes of action to which his environment has led him from immemorial times. Thus, the correspondence of the prehistoric with that which is to-day primitive indicates a high degree of permanence on the part of primitive culture. But, even apart from this consideration, it is apparent that we must really seek primitive man in the inhabited world of the present, since it is here alone that we can gain a relatively accurate knowledge of his characteristics. Our information concerning primitive man, therefore, must be derived from ethnology. We must not seek him _under_ the earth, but _on_ the earth. Just where, however, is he to be found? For decades the natives of Australia were believed to represent a perfect example of primitive culture. And, as a matter of fact, their material culture and some of their mythological ideas still seem to be of a very primitive character. Because of the conjecture that it was here dealing with a relatively primitive type of man, modern anthropology has for two decades applied itself with great partiality to the study of Australian tribes. English and German investigators have given us many works, some of them excellent, treating of the continent of Australia, which appears almost as unique with respect to its population as in its flora and its fauna. From these investigations, however, which are reported particularly in the volume by Howitt published in 1900, in the works of Spencer and Gillen, and, finally, in those of Strehlow, a German missionary, it is apparent that the Australian culture is anything but primitive: it represents, rather, a stage of development already somewhat advanced. In certain respects, indeed, it may contain very primitive elements, such as are not to be found even among tribes that are, on the whole, on a lower level. Australian culture, however, possesses an enormously complex social organization, and this places it above that which may be called primitive.
