I have here summarised the bare outlines of the successive application of black magic as it is believed by sorcerer and outsider alike to be done, and to act in producing disease and death. There can be no doubt that the acts of sorcery are really carried out by those who believe themselves to possess the black powers. It is equally certain that the nervous strain of knowing one’s life to be threatened by a bwaga’u is very great, and probably it is much worse when a man knows that behind the sorcerer stands the might of the chief, and this apprehension certainly contributes powerfully towards the success of black magic. On the other hand, a chief, if attacked, would have a good guard to protect him, and the most powerful wizards to back him up, and also the authority to deal directly with anyone suspected of plotting against him. Thus sorcery, which is one of the means of carrying on the established order, is in its turn strengthened by it.
If we remember that, as in all belief in the miraculous and supernatural, so also here, there is the loophole of counterforces, and of the sorcery being incorrectly or inefficiently applied, spoilt by broken taboos, mispronounced spells, or what not; again, that suggestion strongly influences the victim, and undermines his natural resistance; further that all disease is invariably traced back to some sorcerer or other, who, whether it is true or not, often frankly admits his responsibility in order to enhance his reputation, there is then no difficulty in understanding why the belief in black magic flourishes, why no empirical evidence can ever dispel it, and why the sorcerer no less than the victim, has confidence in his own powers. At least, the difficulty is the same as in explaining many contemporary examples of results achieved by miracles and faith healing, such as Christian Science or Lourdes, or in any cure by prayers and devotion.
Although by far the most important of them all, the bwaga’u is only one among the beings who can cause disease and death. The often-mentioned flying-witches, who come always from the Southern half of the island, or from the East, from the islands of Kitava, Iwa, Gava, or Murua, are even more deadly. All very rapid and violent diseases, more especially such as show no direct, perceptible symptoms, are attributed to the mulukwausi, as they are called. Invisible, they fly through the air, and perch on trees, house-tops, and other high places. From there, they pounce upon a man or woman and remove and hide “the inside,” that is, the lungs, heart and guts, or the brains and tongue. Such a victim will die within a day or two, unless another witch, called for the purpose and well paid, goes in search and restores the missing “inside.” Of course, sometimes it is too late to do it, as the meal has been eaten in the meantime! Then the victim must die.
Another powerful agency of death consists of the tauva’u, non-human though anthropomorphic beings, who cause all epidemic disease. When, at the end of the rainy season the new and unripe yams have come in, and dysentery rages, decimating the villages; or, when in hot and damp years an infectious disease passes over the district, taking heavy toll, this means that the tauva’u have come from the South, and that, invisible, they march through the villages, rattling their lime gourds, and with their sword-clubs or sticks hitting their victims, who immediately sicken and die. The tauva’u can, at will, assume the shape of man or reptile. He appears then as a snake, or crab, or lizard, and you recognise him at once, for he will not run away from you, and he has as a rule a patch of some gaudy colour on his skin. It would be a fatal thing to kill such a reptile. On the contrary, it has to be taken up cautiously and treated as a chief; that is to say, it is placed on a high platform, and some of the valuable tokens of wealth—a polished green stone blade, or a pair of arm-shells, or a necklace of spondylus shell beads must be put before it as an offering.
It is very interesting to note that the tauva’u are believed to come from the Northern coast of Normanby Island, from the district of Du’a’u, and more especially from a place called Sewatupa. This is the very place where, according to Dobuan belief and myth, their sorcery originated. Thus, what to the local tribes of the originating place is ordinary sorcery, practised by men, becomes, when looked at from a great distance, and from an alien tribe, a non-human agency, endowed with such super-normal powers as changing of shape, invisibility, and a direct, infallible method of inflicting death.
The tauva’u have sometimes sexual intercourse with women; several present cases are on record, and such women who have a familiar tauva’u become dangerous witches, though how they practise their witchcraft is not quite clear to the natives.
A much less dangerous being is the tokway, a wood-sprite, living in trees and rocks, stealing crops from the field and from the yam-houses, and inflicting slight ailments. Some men in the past have acquired the knowledge of how to do this from the tokway, and have handed it on to their descendants.
So we see that, except for the very light ailments which pass quickly and easily, all disease is attributed to sorcery. Even accidents are not believed to happen without cause. That this is the case also with drowning, we shall learn more in detail, when we have to follow the Trobrianders in their dangerous sea-trips. Natural death, caused by old age, is admittedly possible, but when I asked in several concrete cases, in which age was obviously the cause, why such and such a man died, I was always told that a bwaga’u was at the back of it. Only suicide and death in battle have a different place in the mind of the natives, and this is also confirmed by the belief that people killed in war, those that commit suicide, and those who are bewitched to death have, each class, their own way to the other world.
This sketch of Trobriand tribal life, belief and customs must suffice, and we shall still have opportunities of enlarging upon these subjects that most matter to us for the present study.
