On most occasions the victim of the sacrifice, be it pig or fowl, is afterwards eaten. But if the sacrifice be to Pulang Gana at the commencement of the farming, the pig and other offerings are conveyed with the beating of gongs to the land prepared for receiving the seed. The pig is killed, its liver and gall examined for divination, the body and other offerings put in the ground, and some _tuak_ (native spirit) poured upon them; a long invocation is then made to Pulang Gana, the god of the land. If a fowl be sacrificed for adultery, its body is thrown away in the jungle. For all ordinary sacrifices a fowl suffices, but on great occasions a pig, being the largest animal the Dyak domesticates, is killed. Anyone may offer these sacrifices. There does not seem to be among the Dyaks any priestly order whose duty it is to officiate at religious ceremonies. Any man who has been fortunate in life, or knows the form of address to be used to the deities on these occasions, may perform the sacrificial function. All that the Dyak hopes to get by his religious ceremonies is material benefits—good crops of paddy, the heads of his enemies, skill in craft, health, and prosperity. Even when there is some idea of the propitiation for sin, as in the slaying of a victim after an act of adultery, the idea of the Dyak is not so much the cleansing of the offender as the appeasing of the anger of the gods, because in their anger the gods may destroy their crops or otherwise give them trouble. There is no idea of seeking for pardon for the offenders. It is merely a compensation for wrong done, and a bargain with the gods to protect their material interests. The longing to communicate with the supernatural is common to all races of mankind. The Dyak has a special means of bringing this about; he has a custom which is called _nampok_. To _nampok_ is to sleep on the top of some mountain, or other lonely place, in the hope of meeting some good spirit from the unseen world. A cemetery is a favourite place to _nampok_ in, because the Dyaks think there is great probability of meeting spirits in such places. The undertaking requires considerable pluck. The man must be quite alone, and he must let no one know of his whereabouts. The spirit he meets may take any form; he may come in human form and treat him kindly, or he may assume a hideous form and attack him.
