[Sidenote: Customs observed by manslayers in British New Guinea.] Among the tribes at the mouth of the Wanigela River, in British New Guinea, “a man who has taken life is considered to be impure until he has undergone certain ceremonies: as soon as possible after the deed he cleanses himself and his weapon. This satisfactorily accomplished, he repairs to his village and seats himself on the logs of sacrificial staging. No one approaches him or takes any notice whatever of him. A house is prepared for him which is put in charge of two or three small boys as servants. He may eat only toasted bananas, and only the centre portion of them--the ends being thrown away. On the third day of his seclusion a small feast is prepared by his friends, who also fashion some new perineal bands for him. This is called _ivi poro_. The next day the man dons all his best ornaments and badges for taking life, and sallies forth fully armed and parades the village. The next day a hunt is organised, and a kangaroo selected from the game captured. It is cut open and the spleen and liver rubbed over the back of the man. He then walks solemnly down to the {126} nearest water, and standing straddle-legs in it washes himself. All young untried warriors swim between his legs. This is supposed to impart his courage and strength to them. The following day, at early dawn, he dashes out of his house, fully armed, and calls aloud the name of his victim. Having satisfied himself that he has thoroughly scared the ghost of the dead man, he returns to his house. The beating of flooring boards and the lighting of fires is also a certain method of scaring the ghost. A day later his purification is finished. He can then enter his wife’s house.”[126.1] In this last case the true nature of such so-called purifications is clearly manifest: they are in fact rites of exorcism observed for the purpose of banning a dangerous spirit.
