If I have stated Mr. Hill-Tout's ideas correctly, he agrees with me in regarding the tribe as formed by aggregation of many more primitive groups. He does not regard the phratries and totem kins as the result of the segmentation of a primordial indiscriminate mass or horde, split up at the injunction of an inspired medicine man, or by a tribal decree. Against our opinion, Mr. Howitt argues that only one writer who "has or had a personal acquaintance with the Australian blacks" accepts it, the Rev. John Matthew. It is accepted, however, as far as "sub-phratries" go (as an alternative hypothesis), by Mr. Hewitt's friend, Dr. Fison.285 But I have given my reasons for not accepting Mr. Howitt's doctrine, and I await some reason for his rejection of mine. Even authors who have "a personal acquaintance with the Australian blacks" should, I venture to think, give their reasons for rejecting one and persisting in another theory of "the probabilities of the case."286 I have shown why I think it improbable that a postulated prehistoric tribe split itself up, for no alleged reason, at the suggestion of a medicine man. Now I am anxious to know why my postulated groups should not make marriage alliance for the reason of securing peace – a very sufficient motive for betrothals.
