With an experience of nearly twenty years in Borneo, during which I came into contact with thousands of the people, I have known of only two instances of theft among the Dyaks. One was a theft of rice. The woman who lost the rice most solemnly and publicly cursed the thief, whoever it might be. The next night the rice was secretly left at her door. The other was a theft of money. In this case, too, the thief was cursed. The greater part of the money was afterwards found returned to the box from which it had been abstracted. Both these incidents show the great dread the Dyak has of a curse. Even an undeserved curse is considered a terrible thing, and according to Dyak law, to curse a person for no reason at all is a fineable offence. A Dyak curse is a terrible thing to listen to. I have only once heard a Dyak curse, and I am sure I do not want to do so again. I was travelling in the Saribas district, and at that time many of the Dyaks there had gone in for coffee-planting; indeed, several of them had started coffee plantations on a small scale. A woman told me that someone had over and over again stolen the ripe coffee-berries from her plantation. Not only were the ripe berries stolen, but the thief had carelessly picked many of the young berries and thrown them on the ground, and many of the branches of the plants had been broken off. In the evening, when I was seated in the public part of the house with many Dyak men and women round me, we happened to talk about coffee-planting. The woman was present, and told us of her experiences, and how her coffee had been stolen by some thief, who, she thought, must be one of the inmates of the house. Then she solemnly cursed the thief. She began in a calm voice, but worked herself up into a frenzy. We all listened horror-struck, and no one interrupted her. She began by saying what had happened, and how these thefts had gone on for some time. She had said nothing before, hoping that the thief would mend his ways; but the matter had gone on long enough, and she was going to curse the thief, as nothing, she felt sure, would make him give up his evil ways. She called on all the spirits of the waters and the hills and the air to listen to her words and to aid her. She began quietly, but became more excited as she went on. She said something of this kind:—
