At almost every death a suspicion of witchcraft arises. The witch-doctor is called in, and proceeds to find out the guilty person. Then woe to the unpopular men, the weak women, and the slaves; for on some of them will fall the accusation that means ordeal by poison, or fire, followed, if these point to guilt, as from their nature they usually do, by a terrible death: slow roasting alive - mutilation by degrees before the throat is mercifully cut - tying to stakes at low tide that the high tide may come and drown - and any other death human ingenuity and hate can devise.
The terror in which witchcraft is held is interesting in spite of all its horror. I have seen mild, gentle men and women turned by it, in a moment, to incarnate fiends, ready to rend and destroy those who a second before were nearest and dearest to them. Terrible is the fear that falls like a spell upon a village when a big man, or big woman is just known to be dead. The very men catch their breaths, and grow grey round the lips, and then every one, particularly those belonging to the household of the deceased, goes in for the most demonstrative exhibition of grief. Long, low howls creep up out of the first silence - those blood-curdling, infinitely melancholy, wailing howls - once heard, never to be forgotten.
The men tear off their clothes and wear only the most filthy rags; women, particularly the widows, take off ornaments and almost all dress; their faces are painted white with chalk, their heads are shaven, and they sit crouched on the earth in the house, in the attitude of abasement, the hands resting on the shoulders, palm downwards, not crossed across the breast, unless they are going into the street.
Meanwhile the witch-doctor has been sent for, if he is not already present, and he sets to work in different ways to find out who are the persons guilty of causing the death.
Whether the methods vary with the tribe, or with the individual witch-doctor, I cannot absolutely say, but I think largely with the latter.
Among the Benga I saw a witch-doctor going round a village ringing a small bell which was to stop ringing outside the hut of the guilty. Among the Cabindas (Fjort) I saw, at different times, two witch-doctors trying to find witches, one by means of taking on and off the lid of a small basket while he repeated the names of all the people in the village. When the lid refused to come off at the name of a person, that person was doomed. The other Cabinda doctor first tried throwing nuts upon the ground, also repeating names. That method apparently failed. Then he resorted to another, rubbing the flattened palms of his hands against each other. When the palms refused to meet at a name, and his hands flew about wildly, he had got his man.
The accused person, if he denies the guilt, and does not claim the ordeal, is tortured until he not only acknowledges his guilt but names his accomplices in the murder, for remember this witchcraft is murder in the African eyes.
If he claims the ordeal, as he usually does, he usually has to take a poison drink. Among all the Bantu tribes I know this is made from Sass wood (sass = bad; sass water = rough water; sass surf = bad surf, etc.), and is a decoction of the freshly pulled bark of a great hard wood forest tree, which has a tall unbranched stem, terminating in a crown of branches bearing small leaves. Among the Calabar tribes the ordeal drink is of two kinds: one made from the Calabar bean, the other, the great ju-ju drink Mbiam, which is used also in taking oaths.
In both the sass-wood and Calabar bean drink the only chance for the accused lies in squaring the witch-doctor, so that in the case of the sass-wood drink it is allowed to settle before administration, and in the bean that you get a very heavy dose, both arrangements tending to produce the immediate emetic effect indicative of innocence. If this effect does not come on quickly you die a miserable death from the effects of the poison interrupted by the means taken to kill you as soon as it is decided from the absence of violent sickness that you are guilty.
The Mbiam is not poisonous, nor is its use confined, as the use of the bean is, entirely to witch palaver; but it is the most respected and dreaded of all oaths, and from its decision there is but one appeal, the appeal open to all condemned persons, but rarely made - the appeal to Long ju-ju. This Long ju-ju means almost certain death, and before it a severe frightening that is worse to a negro mind than mere physical torture.
