over of a woman may be also regarded as expressing the public sanction of marriage. We must still notice an interesting ceremony amongst the Warramunga, Tjinjilli, Gnanji, Binbinga, Mara, which consists of some hair being given by the maternal uncle of the girl to her future husband. This hair is worn by him under his arm-band; "it is a simple plan of publicly announcing the fact" of the betrothal.[105] Amongst the Binbinga there is a form of betrothal. The future husband must present his father-in-law with boomerangs, etc., and must avoid him, but goes on giving him presents.[106] [99] Compare _Nat. Tr._, chap, iii., pp. 92 _sqq._, and _Nor. Tr._, chap. iv., pp. 133 _sqq._ [100] _Nat. Tr._, pp. 92 _sqq._ [101] For detailed description see _Nat. Tr._, pp. 92, 93 (Arunta and Ilpirra), p. 94 (S. Arunta), pp. 94, 95 (Kaitish), p. 95 (the remaining six tribes). These ceremonies differ only in details from each other in different tribes. [102] _Nor. Tr._, p. 135. [103] _Ibid._, p. 135. [104] According to Lord Avebury; see _Nat. Tr._, p. 96. [105] _Nor. Tr._, pp. 603, 604. [106] _Ibid._, p. 77, footnote. Among some tribes of South Queensland (Bunya-Bunya country) marriage was arranged without any consent of the contracting parties. Sometimes it was arranged when the girl was an infant, and she was then promised to some man of importance or influence. Sometimes exchange of females took place at large tribal gatherings. Elopement was known in these tribes, and a fight decided whether it was legalized or not.[107] [107] Tom Petrie, _loc. cit._, pp. 59, 60. We find a ceremony of betrothal among the Kuinmurbura. "The parents having painted the girl and dressed her hair with feathers, her male cousin takes her to where her future husband is sitting cross-legged in silence, and seats her at his back and close to him. He who has brought the girl after a time removes the feathers from her hair and places them in the hair of her future husband, and then leads the girl back to her parents." The future son-in-law must give presents of game to the father of his promised wife.[108] [108] Howitt, _Trans. R.S.V._, p. 118. We read about the natives of Moreton Bay, that marriage is generally contracted with the consent of the relatives of both parties and the approval of the tribe. As a form of betrothal they join their hands. The stealing of women from neighbouring tribes ends usually in war.[109] [109] J. D. Lang, _loc. cit._, p. 337. Among the Herbert River natives, exchange of sisters or daughters is the commonest way of obtaining wives.[110] Girls are promised to their respective husbands[111] in infancy and delivered at the age of nine or ten years.
