dissect his dead body, extract the old viscera, and replace them with a new set in the manner already described.(627) (M183) In this account of the manner in which medicine-men obtain their magical powers not only are the supposed death and resurrection of the novice worthy of attention, but also the exchange of internal organs which in the Binbinga and Mara tribes is supposed to be effected between the man and the spirit;(628) for this exchange resembles that which, on the theory I have suggested, may be thought to take place between a lad and his totem at the ceremonies of initiation which mark the momentous transition from boyhood to manhood. Further, the bodily mutilation which is the visible sign of the medicine-man’s initiation (for however the hole may be made it certainly exists in the tongues of regular Arunta practitioners) corresponds to the bodily mutilations of other sorts, which in many savage tribes attest to the world that the mutilated persons are fullgrown men. What the precise meaning of such mutilations may be, still remains very obscure; but they seem in some cases to be directly associated with the conception of death and resurrection. (M184) This association certainly comes out plainly in the rites of initiation through which in some parts of New Guinea all lads must pass before they attain to the status of adults. The rites are observed by a group of tribes who occupy contiguous territories about Finsch Harbour and Huon Gulf in German New Guinea. The tribes in question are the Yabim, the Bukaua, the Kai, and the Tami. All of them except the Kai belong to the Melanesian stock and are therefore presumably immigrants from the adjoining islands; but the Kai, who inhabit the rugged, densely wooded, and rainy mountains inland from Finsch Harbour, belong to the aboriginal Papuan stock and differ from their neighbours in speech as well as in appearance. Yet the rites of initiation which all these tribes celebrate and the beliefs which they associate with them are so similar that a single description will apply accurately enough to them all. All of them, like many Australian tribes, require every male member of the tribe to be circumcised before he ranks as a full-grown man; and the tribal initiation, of which circumcision is the central feature, is conceived by them, as by some Australian tribes, as a process of being swallowed and disgorged by a mythical monster, whose voice is heard in the humming sound of the bull-roarer. Indeed the New Guinea tribes not only impress this belief on the minds of women and children, but enact it in a dramatic form at the actual rites of initiation, at which no woman or uninitiated person may be present. For this purpose a hut about a hundred feet long is erected either in the village or in a lonely part of the forest. It is modelled in the shape of the mythical monster; at the end which represents his head it is high, and it tapers away at the other end. A betel-palm,
