them, which I do not desire to apply to the analogous organisations found in Australia; but have used the term "clan" to mean the principal geographical and territorial division of a tribe, in which descent is in the male line. Then some term seemed necessary to denote the divisions of a tribe in which descent is counted in the female line, and for this, as before stated, I use "horde," without including in my meaning any reference to the use made of it by other writers on anthropological theories.
The division of the people of the tribe into two classes is the foundation from which the whole social organisation of the native tribes of Australia has been developed.
In two tribes very far apart from each other, not only in geographical position but in customs, there are analogous legends purporting to explain how this division of the tribe came about. One is a Dieri legend from Central Australia; and the other from the Wurunjerri in Southern Victoria. I have considered them fully in Chapter VIII., and need only mention here that they agree in the essential point that the division of the tribe was made with intent to regulate the relations of the sexes.
These legends have no historical authority, but are good evidence of the belief of these aborigines that this universal basis of their social system was brought about by intention, and according to one of the legends had a supernatural sanction.
From what I know of the Australian savage I can see very clearly how such a social change might be brought about. They universally believe that their deceased ancestors and kindred visit them during sleep, and counsel or warn them against dangers, or communicate to them song-charms against magic. I have known many such cases, and I also know that the medicine-men see visions that are to them realities. Such a man if of great repute in his tribe might readily bring about a social change, by announcing to his fellow medicine-men a command received from some supernatural being such as Kutchi of the Dieri, Bunjil of the Wurunjerri, or Daramulun of the Coast Murring. If they received it favourably, the next step might be to announce it to the assembled headmen at one of the ceremonial gatherings
