probable evolution of Australian tribal society.[1] The theory thus suggested makes little demand on deliberate legislation, as we shall see later. DELIBERATE ARRANGEMENT This I take to be important. It seems well to avoid, as far as possible, the hypothesis of deliberate legislation in times primeval, involving so sweeping a change as the legal establishment of exogamy through a decree based on common consent by an exogamous ‘Bisection’ consciously made. Exogamy must have been gradually evolved. But, if we begin with Mr. Howitt’s original undivided commune, and suppose a deliberate bisection of it into two exogamous phratries, each somehow containing different totems; or if we suppose a tribe of only two totems, and imagine that the tribe deliberately made these totems exogamous, which they had not been before, and then subdivided them into many other totem groups, we see, indeed, why persons of the same totem may not intermarry. They now, after the decree, belong to the same exogamous ‘phratry’ within which marriage is deliberately forbidden. But, on this theory, I find no escape from the conclusion that the ‘bisection’ into ‘phratries’ was the result of a deliberate decree, intended to produce exogamy--for the bisection has not, and apparently cannot have, any other effect. Now I can neither imagine a motive for such a decree, nor any mode, in such early times, of procuring for it common consent. At this point we have laboured, and to it we shall return, observing that our hypothesis makes much less appeal to such early and deliberate legislation. TOTEMS ALL THE WAY In any case, by Mr. Fison’s and Mr. Howitt’s theory and our own, we have totems almost all the way: totems in the so-called ‘primary divisions’ (phratries); totems in the so-called _gentes_, and all these divisions (setting the Arunta apart) are strictly exogamous. The four or eight ‘classes,’ on the other hand, are apparently not of totemic origin. However much the systems may be complicated and inter-twisted, the basis of the whole, except of the four or eight ‘classes,’ is, I think, the totem exogamous prohibition. There are many examples of the type; thus the Urabunna ‘are divided into two exogamous intermarrying classes, which are respectively called Matthurie and Kirarawa, and the members of these again are divided into a series of totemic groups, for which the native name is _Thunthunnie_. A Matthurie man must marry a Kirarawa women’ (as in the system of the Kamil-speaking tribes, or Kamilaroi, reported on by Mr. Fison)--‘and not only this, but a man of one totem must marry a woman of another totem.’ This is precisely what I should expect. It works out thus: { Old Local Totem Group } Matthurie. { New ‘Phratry’ } { Old Local Totem Group } Kirarawa. { New ‘Phratry’ }
