Singing to the accompaniment of drums, gongs, or the blian's shield, and dancing to the sound of drums or gongs, are further inducements brought to bear on the friendly antohs, which are attracted thereby. According to the belief which prevails in their primitive minds, the music and dancing also have a deterrent effect upon the malicious ones. Both evil and good antohs are believed to congregate on such occasions, but the dancing and music have a terrifying effect on the former, while on the latter they act as an incentive to come nearer and take possession of the performers or of the beneficiary of the function by entering through the top of the head. A primitive jews'-harp, universally found among the tribes, is played to frighten away antohs, and so is the flute. A kindly antoh may enter a man and become his guardian spirit, to whom he occasionally offers food, but it never remains long because that would make the man insane. One must not step over a person, because a benevolent antoh that may be in possession is liable to be frightened away, say the Katingans and other Dayaks. In dancing with masks, which is much practised on the Mahakam, the idea is that the antoh of the animal represented by the mask enters the dancer through the top of his head. The Penihings and Long-Glats of the Mahakam have an interesting belief in the existence of a friendly antoh which reminded me of the superstition of the "Nokken" in the rivers of Norway. It lives in rivers, is very rarely beheld by mortals, and the one who sees it becomes rich beyond dreams of avarice. The Long-Glats call it sangiang, a survival of Hindu influence. An old man in Long Tujo is reported to have seen this antoh, and according to him it had the appearance of a woman sitting underneath the water. No doubt other tribes have the same belief. The most famous of antohs is the nagah, which may be good or evil, according to the treatment received from mortals, and being very powerful its help and protection are sought in a manner later to be described in connection with my travels on the Mahakam. The nagah guards underneath as well as above the surface of water and earth, but the air is protected by three birds which are messengers, or mail carriers, so to speak. They are able to call the good antoh and carry food to him; they are also attendants of man and watch over him and his food. Fowls and pigs are sacrificed to them as payment. They are--the tingang (hornbill), the sankuvai (formerly on earth but now only in heaven), and the antang (red hawk). As these birds are called by the same names in the tribes of the Katingans, Ot-Danums, Kahayans, and others, it may be presumed that their worship is widely prevalent in Borneo.
