When the Dyaks wish to abandon an old habitation in favour of a new one, a general meeting of the inhabitants is held to consider the matter, and the desirability of building a new house is fully discussed. Sometimes it happens that some families do not agree with the wishes of the majority, and these families split off and join another house. If a move be decided on, a few experienced men are deputed to choose a site, and to report on its adaptability. There are several matters to be taken into account. The site must be for preference on rising ground, and be near a good supply of water. There must also be some jungle near, where the inmates can get their firewood, and there must be large tracts of land not far away where they can plant their paddy. When the new house has to be built on the low-lying, marshy ground in the lower reaches of the river, the choice is not difficult. All that is necessary is to choose a part of the river where the current is not very strong. But in the hill country it is not easy to find a site where the ground is fairly level, and can accommodate a large house of thirty or forty families. Before building on the chosen site the omen birds are consulted. If the omens be favourable, all the men and lads turn out immediately with axes and choppers to cut down the trees of the jungle, which are then left to dry. Another meeting is then held to decide who is to be the _tuai_, or headman, of the new house, and to settle the size and the sequence of the rooms. The next move is to appoint a time for all the people to meet at the site of the new village. The ground is then cleared. All the timber is carried off, as it is considered unfortunate to burn it. The ground is measured out for the different rooms belonging to the different families, and pegs are put in where the posts have to stand. A piece of bamboo is then stuck in the ground, filled with water and covered with leaves. A spear and a shield are placed beside it, and the whole is surrounded by a wooden rail. The rail is to prevent the bamboo from being upset by wild animals, and the weapons are to warn strangers not to touch it. A few people remain to keep watch, and to make a great deal of noise with brass gongs and drums to frighten away the evil spirits. If in the early morning they find there is much evaporation, the place is considered unhealthy, and is abandoned. If all be well, the building of the house is begun. Each family must kill a fowl or a pig before the holes for the posts can be dug, and the blood must be smeared on the sharpened ends and sprinkled on the posts to propitiate Pulang Gana, the tutelary deity of the earth. They begin by making the holes for the headman’s quarters, and then work simultaneously to left and right of it. The posts, of which there are a great number, are about twelve inches or less in diameter, and are of bilian or other hard wood so as not to rot in the earth. A hole four feet deep is made to receive each post.
