Some Bantu tribes entertain even more exaggerated notions of the virulent infection spread by a woman who has had a miscarriage and has concealed it. An experienced observer of these people tells us that the blood of childbirth "appears to the eyes of the South Africans to be tainted with a pollution still more dangerous than that of the menstrual fluid. The husband is excluded from the hut for eight days of the lying-in period, chiefly from fear that he might be contaminated by this secretion. He dare not take his child in his arms for the three first months after the birth. But the secretion of childbed is particularly terrible when it is the product of a miscarriage, especially _a concealed miscarriage._ In this case it is not merely the man who is threatened or killed, it is the whole country, it is the sky itself which suffers. By a curious association of ideas a physiological fact causes cosmic troubles!" As for the disastrous effect which a miscarriage may have on the whole country I will quote the words of a medicine-man and rain-maker of the Ba-Pedi tribe: "When a woman has had a miscarriage, when she has allowed her blood to flow, and has hidden the child, it is enough to cause the burning winds to blow and to parch the country with heat. The rain no longer falls, for the country is no longer in order. When the rain approaches the place where the blood is, it will not dare to approach. It will fear and remain at a distance. That woman has committed a great fault. She has spoiled the country of the chief, for she has hidden blood which had not yet been well congealed to fashion a man. That blood is taboo. It should never drip on the road! The chief will assemble his men and say to them, 'Are you in order in your villages?' Some one will answer, 'Such and such a woman was pregnant and we have not yet seen the child which she has given birth to.' Then they go and arrest the woman. They say to her, 'Show us where you have hidden it.' They go and dig at the spot, they sprinkle the hole with a decoction of two sorts of roots prepared in a special pot. They take a little of the earth of this grave, they throw it into the river, then they bring back water from the river and sprinkle it where she shed her blood. She herself must wash every day with the medicine. Then the country will be moistened again (by rain). Further, we (medicine-men), summon the women of the country; we tell them to prepare a ball of the earth which contains the blood. They bring it to us one morning. If we wish to prepare medicine with which to sprinkle the whole country, we crumble this earth to powder; at the end of five days we send little boys and little girls, girls that yet know nothing of women's affairs and have not yet had relations with men. We put the medicine in the horns of oxen, and these children go to all the fords, to all the entrances of the country. A little girl turns up the soil with her mattock, the others dip a branch in the horn and sprinkle the inside of the hole saying, 'Rain! rain!' So we remove the misfortune which the women have brought on the roads; the rain will be able to come. The country is purified!"
