[Sidenote: Illicit love supposed to blight the fruits of the earth.] Again, the sympathetic relation supposed to exist between the commerce of the sexes and the fertility of the earth manifests itself in the belief that illicit love tends, directly or indirectly, to mar that fertility and to blight the crops.[383] Such a belief prevails, for example, among the Karens of Burma. They imagine that adultery or fornication has a powerful influence to injure the harvest. Hence if the crops have been bad for a year or two, and no rain falls, the villagers set down the dearth to secret sins of this kind, and say that the God of heaven and earth is angry with them on that account; and they all unite in making an offering to appease him. Further, whenever adultery or fornication is detected, the elders decide that the sinners must buy a hog and kill it. Then the woman takes one foot of the hog, and the man takes another, and they scrape out furrows in the ground with each foot, and fill the furrows with the blood of the hog. Next they scratch the ground with their hands and pray: “God of heaven and earth, God of the mountains and hills, I have destroyed the productiveness of the country. Do not be angry with me, do not hate me; but have mercy on me, and compassionate me. Now I repair the mountains, now I heal the hills, and the streams and the lands. May there be no failure of crops, may there be no unsuccessful labours, or unfortunate efforts in my country. Let them be dissipated to the foot of the horizon. Make thy paddy fruitful, thy rice abundant. Make the vegetables to flourish. If we cultivate but little, still grant that we may obtain a little.” After each has prayed thus, they return to the house and say they have repaired the earth.[384] The Battas of Sumatra think that if an unmarried woman is big with child, it is necessary to give her in marriage at once, even to a man of lower rank; for otherwise the people will be infested by tigers, and the crops in the field will not yield an abundant return. The crime of incest, in their opinion, would blast the whole harvest if the wrong were not speedily repaired. Epidemics and other calamities that affect the whole people are almost always traced by them to incest, by which is to be understood any marriage that conflicts with their customs.[385]
