The Mbiam oath formula I was able to secure in the upper districts of the Calabar. One form of it runs thus, and it is recited before swallowing the drink made of filth and blood: -
“If I have been guilty of this crime,
“If I have gone and sought the sick one’s hurt,
“If I have sent another to seek the sick one’s hurt,
“If I have employed any one to make charms or to cook bush,
“Or to put anything in the road,
“Or to touch his cloth,
“Or to touch his yams,
“Or to touch his goats,
“Or to touch his fowl,
“Or to touch his children,
“If I have prayed for his hurt,
“If I have thought to hurt him in my heart,
“If I have any intention to hurt him,
“If I ever, at any time, do any of these things (recite in full),
“Or employ others to do these things (recite in full),
“Then, Mbiam! Thou deal with me.”
This form I give was for use when a man was sick, and things were generally going badly with him, for it is not customary in cases of disease to wait until death occurs before making an accusation of witchcraft. In the case of Mbiam being administered after a death this long and complicated oath would be worded to meet the case most carefully, the future intention clauses being omitted. In all cases, whenever it is used, the greatest care is taken that the oath be recited in full, oath-takers being sadly prone to kiss their thumb, as it were, particularly ladies who are taking Mbiam for accusations of adultery, in conjunction with the boiling oil ordeal. Indeed, so unreliable is this class of offenders, or let us rather say this class of suspected persons, that some one usually says the oath for them.
From the penalty and inconveniences of these accusations of witchcraft there is but one escape, namely flight to a sanctuary. There are several sanctuaries in Congo Français. The great one in the Calabar district is at Omon. Thither mothers of twins, widows, thieves, and slaves fly, and if they reach it are safe. But an attempt at flight is a confession of guilt; no one is quite certain the accusation will fall on him, or her, and hopes for the best until it is generally too late. Moreover, flying anywhere beyond a day’s march, is difficult work in West Africa. So the killing goes on and it is no uncommon thing for ten or more people to be destroyed for one man’s sickness or death; and thus over immense tracts of country the death-rate exceeds the birth-rate. Indeed some of the smaller tribes have thus been almost wiped out. In the Calabar district I have heard of an entire village taking the bean voluntarily because another village had accused it en bloc of witchcraft. Miss Slessor has frequently told me how, during a quarrel, one person has accused another of witchcraft, and the accused has bolted off in a towering rage and swallowed the bean.
The witch-doctor is not always the cause of people being subjected to the ordeal or torture. In Calabar and the Okÿon districts all the widows of a dead man are subjected to ordeal.
They have to go the next night after the death, before an assemblage of chiefs and the general surrounding crowd, to a cleared space where there is a fire burning. A fowl is tied to the right hand of each widow, and should that fowl fail to cluck at the sight of the fire the woman is held guilty of having bewitched her dead husband and is dealt with accordingly.
Among the Bantu, although the killing among the wives from the accusation of witchcraft is high, some of them being almost certain to fall victims, yet there is not the wholesale slaughter of women and slaves sent down with the soul of the dead that there is among the Negroes.
In doubtful cases of death, i.e. in all cases not arising from actual violence, when blood shows in the killing, the Bantu of the S.W. Coast make post-mortem examinations. Notably common is this practice among the Cameroons and Batanga region tribes. The body is cut open to find in the entrails some sign of the path of the injected witch.
I am informed that it is the lung that is most usually eaten by the spirit. If the deceased is a witch-doctor it is thought, as I have mentioned before, that his familiar spirit has eaten him internally, and he is opened with a view of securing and destroying his witch. In 1893 I saw in a village in Kacongo five unpleasant-looking objects stuck on sticks. They were the livers and lungs, and in fact the plucks, of witch-doctors, and the inhabitants informed me they were the witches that had been found in them on post-mortems and then been secured.
Mrs. Grenfell, of the Upper Congo, told me in the same year, when I had the pleasure of travelling with her from Victoria to Matadi, that a similar practice was in vogue among several of the Upper Congo tribes.
