Again, there are dozens of such departments,[12] which implies the existence of dozens of organised and co-operative totem groups: not of an original poor pair of such groups alone. Can we believe that, on Mr. Frazer’s earlier theory, the Thlinkets formed but two such groups, one ‘charged with’ the duty to mollify the Wolf, the other to take care of the interests of the Raven? Manifestly this is unlikely. I elsewhere oppose this theory of the magical Origin of Totemism, made at first to fit the case of the Arunta and cognate tribes. If organised co-operation in magic is the source of Totemism, we may be pretty confident that no tribe began by appointing one half of all its members to do magic to propagate ravens, and the other half to mollify wolves. This would indicate, in the magical and co-operative tribe, a most oddly limited and feebly capitalised flotation of the company--merely ‘Wolf and Raven.’ No tribe would select ravens as the article of food which most required careful propagation and preservation, even if the Wolf most demanded to be propitiated and mollified. The new Australian facts (whatever their interpretation) are fatal to the older idea that a tribe could have had only two original totems: an idea which we may perhaps regard as now abandoned, at least by Mr. Frazer. Thus Mr. Spencer himself remarks that, in Arunta tradition, there were numbers of totem groups before the great dichotomous division was made. That is my own opinion: though I do not hold it for Mr. Spencer’s reasons, or believe in any ‘bisection.’ MR. SPENCER’S THEORIES OF THE BISECTION It will be noted that Mr. Spencer’s original totem groups existed for magical purposes only, and were not exogamous. ‘The traditions of the Arunta tribe point to a very definite introduction of an exogamic system long after the totemic groups were fully developed, and, further, they point very clearly to the fact that the introduction was due to the deliberate action of certain ancestors. Our knowledge of the natives leads us to the opinion that it is quite possible that this really took place, that the exogamic groups were deliberately introduced so as to regulate marital relations.’
