Some idea of the method in which the Dyaks carry out their system of omens may be gathered from what is done at the commencement of the yearly rice-farming. Some man who has the reputation of being fortunate, and has had large paddy crops, will be the augur, and undertake to obtain omens for a large area of land on which he and others intend to plant. The Dyaks begin clearing the ground of jungle and high grass when the Pleiades appear at a certain height above the horizon at sunset. Some little time before this the augur sets about his work. He will have to hear the cry of the _nendak_, the _katupong_, and the _beragai_, all on his left. If these cries come from birds on his right, they are not propitious. The cries of the other sacred birds must sound on his right. He goes forth in the early morning, and wanders about the jungle till the cry of the _nendak_ is heard on his left. He will then break off a twig of anything growing near, and take it home and put it in a safe place. But it may happen that some other omen bird or animal is first to be seen or heard. In that case he must give the matter up, return, and try his chance another day. Thus, sometimes several days pass before he has obtained his first omen. When he has heard the _nendak_, he will then listen for the _katupong_ and the other birds in the necessary order. There is always the liability of delays caused by the wrong birds being heard, and it may possibly be a month or more before he obtains all those augural predictions, which will give him confidence that his farming for the year will be successful. When the augur has collected a twig for each bird he has heard, he takes these to the land selected for farming, buries them in the ground, and with a short form of address to the birds and to Pulang Gana—the god of the Earth—clears a small portion of the ground of grass or jungle, and then returns home. The magic virtues of the birds have been conveyed to the land, and the work of clearing it for planting may be begun at any time. The sacred birds can be bad omens as well as good. If heard on the wrong side, or in the wrong order, the matter in hand must be postponed or altogether abandoned, unless a subsequent conjunction of good omens occurs, which in the judgment of old experts more than counterbalances the bad omens. I have mentioned the omens necessary before planting the seed. In a similar manner, before beginning to build a house, or starting on a war expedition, or undertaking any new line of action, certain omens are required if good fortune is to attend them and the Fates be propitious. For house-building, the cries of the same birds are required, and in the same order as before planting the seed. But for a war expedition, birds heard on the right hand are best, except in the case of the _nendak_, which may be heard either on the right or on the left hand side.
