We may commence with evidence of the survival of the most primitive human trait, the condition of hostility among the local groups produced by the struggle for women. "The possession of a girl appears to be connected with all their ideas of fighting ... after a battle the girls do not always follow their fugitive husbands from the field, but frequently go over as a matter of course to the victors, even with young children on their backs."[367] Mr. Curr puts the evidence even more definitely in a primitive setting when he informs us of "the young bachelors of the tribe carrying off some of the girl wives of the grey-beards," leaving the old territory and settling at the first convenient place within thirty or forty miles of the old territory. I call this state of things "survival,"[368] because it is the existence in totemic society of the fundamental basis of pre-totemic society. It is checked in Australian totemic society by rules which show a strong development from the primitive. Thus the successful warrior may not take any of his captives to himself; "if a warrior took to himself a captive who belonged to a forbidden class, he would be hunted down like a wild beast," is the evidence of Mr. Fison, who allows it to be "a strong statement, but it rests upon strong evidence."[369] This is the exogamous class system operating even in the case of conflict, when men have resorted to their primitive instincts and their primitive methods. This discovery of primitive hostility accompanying the obtaining of wives leads us to look for other survivals of the earliest conditions, and we come upon mother-right groups in which the females in each local group are the sexual companions of males from outside their own social group. This is shown by the Kamilaroi organisation, where "a woman is married to a thousand miles of husbands."[370] This phrase may be textually an exaggeration of actual fact, but it undoubtedly expresses a condition of things which actually existed. Women in Australian society must look outside their class, and in general outside their totem, for their sexual mates, and they must expect to be claimed as rightful sexual mates by men whom they have never seen and who live at great distances. Carry this state of things but a few steps back, and we must come to a condition of localised female groups with males moving from group to group. Surely there is something more here than savage organisation. The something more is the development into a system of one of the results of the enforced migratory conditions of early man, namely, the migratory instincts of the males moving outside the female local groups and thus producing natural exogamy. This is what appears to me to be clearly a distinct element in the Australian system. But there is a new element in juxtaposition with it. The new element is the organisation into marriage classes--not every man from without, but only special men from without, are allowed the sexual companionship.
