In reviewing this material, the first thing to be noted is a considerable geographical variety of custom and law in sexual matters. There are clear and radical differences between the South-eastern tribes, the South Central, North Central, and Northern Queensland tribes. The views on sexual morality apparently differ as much as the actual practices. Whereas in Victoria, South-eastern New South Wales, and the Southern territory of South Australia there are no traces of regulated licence, or at least not in a very conspicuous form--in the South Central tribes the features of _Pirrauru_ relations; in the Central and North Central different forms of ceremonial licence are highly developed, and play an important part in tribal life. In Queensland there does not seem to exist such a very strict sexual morality, as far as we can gather from our statements. Our five statements from West Australia do not give a very clear picture. Undoubtedly these geographical differences, as here indicated, must be conceived as merely rough approximations. There are too many contradictions between the statements concerning the South-eastern area; the data as to Queensland and West Australia are too few and vague to allow anything beyond mere generalities. But broadly, as is indicated above, these local differences undoubtedly exist. Besides the data contained in the statements there is, to confirm this view, the opinion of A. W. Howitt. In his article on the tribal and social organization in Australia, this writer directly points out the radical differences existing between the South Central and the South-eastern tribes in sexual matters; and as he knew from personal acquaintance or from reliable informants the whole area, we may consider this geographical difference as thoroughly established.[296] [296] See _Smith. Rep._ for 1883, pp. 804 _sqq._ Chap. iv. on "Marital groups," p. 810, and _Trans. R.S.V._, pp. 115 _sqq._ Let us now draw some general conclusions from the evidence. The points selected at the outset for special attention were: first, the problem of the rights, privileges, and restrictions of the husband in sexual matters; second, the question how is chastity in general, considered and valued? third, a survey of the cases of ceremonial or regulated licence.
