[Sidenote: Similar views held by the Battas of Sumatra.] The Battas of Sumatra in like manner think that if an unmarried woman is with child, she must be given in marriage at once, even to a man of lower rank; for otherwise the people will be infested with tigers, and the crops in the fields will not be abundant. They also believe that the adultery of married women causes a plague of tigers, crocodiles, or other wild beasts. 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.[46.3] The natives of Nias, an island to the west of Sumatra, imagine that heavy rains are caused by the tears of a god weeping at the commission of adultery or fornication. The punishment for these crimes is death. The two delinquents, man and woman, are buried in a narrow grave with only their heads projecting above ground; then their throats are stabbed with a spear or cut with a knife, and the grave is filled up. Sometimes, it is said, they are buried alive. However, the judges are not always incorruptible and the injured family not always inaccessible to the allurement of gain; and pecuniary compensation is sometimes accepted as a sufficient salve for wounded honour. But if the wronged man is a chief, the culprits must surely die. As a consequence, perhaps, of this severity, the crimes {47} of adultery and fornication are said to be far less frequent in Nias than in Europe.[47.1]
