Deeper reasons exist. German missionaries have been labouring for a number of years among the tribes on the north-eastern coast of New Guinea. In view of the various difficulties attending the investigation of the beliefs of these tribes the latest scientific explorer of the country called in the aid of some of the more experienced {6} of the missionaries. He thus sums up the position: “The heathen Papuan is a reticent fellow, and no power in the world can move him to disclose the secrets of his fathers. He has too much fear of the vengeance of the spirits and of the sorcerers, who would infallibly kill him if he betrayed the smallest thing. Long years of work accomplished with endless patience have been necessary to convince the Black that sorcery is powerless,--that it is all lies and deceit. Only if he is about to be baptized will he voluntarily deliver up to his teacher his knowledge of witchcraft and its methods. In plain terms, he feels the need on this point to lighten both his conscience and his pocket.”[6.1] Reasons of this order have never been better put than by an eminent French anthropologist whose untimely death a few years ago was a serious blow to the cause of science. Reviewing the work of a lady for whom English colleagues yet mourn, he says: “The savage does not like to speak of his belief; he fears the contemptuous mockery of the Whites. Perhaps, too, he fears to give an advantage over himself, in allowing more to be known than is fitting of the rites by which he tries to conciliate the benevolence of the spirits, or to turn away their disfavour from his hut and his plantations. To make known his resources for the fight would be to half-disarm him; surrounded with supernatural dangers, he does not willingly indicate the supernatural means by which he guarantees himself against them.”[6.2] One other reason may be added to these: a reason probably operative in many more cases than enquirers have been aware of. The things after which they ask are often revealed only to the initiate. An {7} outsider, one who is not known to be, or at least treated as, an initiate, will seek in vain by means direct or indirect for information on these matters. A stony silence or repeated lies are all he will get. This has been the cause of much mystification and many contradictory statements about tribes in various parts of the world, not the least in Australia.[7.1]
