The Sibuyaus, though they do not consider the sexual intercourse of their young people as a positive crime, yet are careful of the honour of their daughters, as they attach an idea of great indecency to promiscuous connection. They are far advanced beyond their brethren in this respect, and are of opinion that an unmarried girl proving with child must be offensive to the superior powers, who, instead of always chastising the individual, punish the tribe by misfortunes happening to its members. They, therefore, on the discovery of the pregnancy fine the lovers, and sacrifice a pig to propitiate offended Heaven, and to avert that sickness or those misfortunes that might otherwise follow; and they inflict heavy mulcts for every one who may have suffered from any severe accident, or who may have been drowned within a month before the religious atonement was made; lighter fines are levied if a person be simply wounded. As these pecuniary demands fall upon the families of both parties, great care is taken of the young girls, and seldom is it found necessary to sacrifice the pig. After marriage the women also are generally chaste, though cases of adultery are occasionally brought before the Orang Kayas. Among the Dayaks on the Batang Lupar, however, unchastity is more common; but the favours of the women are generally confined to their own countrymen, and usually to one lover. Should the girl prove with child, it is an understanding between them that they marry, and men seldom, by denying, refuse to fulfil their engagements. Should, however, the girl be unable to name the father, she is exposed to the reproaches of her relatives, and many to escape them have taken poison. In respectable families they sacrifice a pig, and sprinkle the doors with its blood, to wash away the sin; and the erring maiden’s position is rendered so uncomfortable that she generally tries to get away from home. In the account of the Land Dayaks, I will mention the manner in which the young lover approaches the curtains of his mistress. As this seldom ends in immorality, it may be likened to the Welch and Afghan bundling. The Sea Dayaks have the same practice of seeking the girls at night; and as the favoured lover is seldom refused entrance to the curtains, it may be compared to the system of company-keeping which obtains in many of our agricultural counties, where the brides have children a couple of months after marriage. The morality of the Sea Dayaks is, perhaps, superior to the Malays, but inferior to that of the Land Dayaks.
