Adherents of the theory of original promiscuity have interpreted these ideas also as a survival of unrestrained sexual conditions, and thus as indicative of the fact that paternity was at one time unknown. A closer acquaintance with the phenomena, however, shows that this can scarcely be the case. Thus, the idea of the Warramunga that it is the totem ancestors of a woman's husband and not those of any other man that pass over into her, clearly presupposes a state of marriage, as does also the further fact that these same tribes reckon descent in the line of the father and not in that of the mother. Moreover, the passing of the totem ancestor into the woman is generally accompanied by magical ceremonies, such as the swinging of bull-roarers, or contact with churingas. Or, the totem ancestor may appear to the woman in sleep or in a waking vision. On the Banks Islands, strange to say, we find conception totemism without any trace of tribal totemism. The manner of reception of the totem ancestor also differs; the woman eats of the flesh of her husband's totem animal, which, since there is no tribal totemism, is in this case a personal, protective totem. Thus, conception totemism represents something of an exception in that the eating of the totem is not forbidden, as it generally is, but rather constitutes a sort of cult act, as it also does in certain other cases. In Australia, moreover, conception totemism is to be found only among several of the northern tribes, to whom it may at one time have come from Melanesia. Because of the primitive nature of the ideas connected with conception totemism, particularly when, as among the Aranda, the husband is ignored and it is believed that conception is mediated only by the totem ancestor, the northern tribes just referred to have sometimes been regarded as the most primitive. There are some writers, on the other hand, by whom the possibility of such ideas is denied on the ground that these very tribes must be familiar with the process of procreation in the animal world. But this does not prove the case. When, however, we learn that the older men of the tribe themselves no longer entertain the belief in magical generation, particularly as the exclusive factor, whereas, on the other hand, this is still taught to the young men, and especially to the children, we may well call to mind our own childish notions about the stork that brings the babies. Why might something similar not occur among the Australians, and the belief possibly retain credence somewhat beyond the age of childhood?
