chief of Dayaks in Sarawak and was followed by Tun Temenggong Jugah Anak Barieng who was one of the main signatories for the formation of the Federation of Malaysia between Malaya, Singapore, Sabah and Sarawak with Singapore expelled later on. He was said to be the "bridge between Malaya and East Malaysia". The latter was fondly called "Apai" by others, which means father. He received no western or formal education. The most salient feature of Dayak social organisation is the practice of Longhouse domicile. This is a structure supported by hardwood posts that can be hundreds of metres long, usually located along a terraced river bank. At one side is a long communal platform, from which the individual households can be reached. The Iban of the Kapuas and Sarawak have organised their Longhouse settlements in response to their migratory patterns. Iban longhouses vary in size, from those slightly over 100 metres in length to large settlements over 500 metres in length. Longhouses have a door and apartment for every family living in the longhouse. For example, a longhouse of 200 doors is equivalent to a settlement of 200 families. The tuai rumah (longhouse chief) can be aided by a tuai burong (bird leader), tuai umai (farming leader), and a manang (shaman). Nowadays, each longhouse will have a Security and Development Committee and ad hoc committee will be formed as and when necessary for example during festivals such as Gawai Dayak. The Dayaks are peace-loving people who live based on customary rules or adat asal which govern each of their main activities. The adat is administered by the tuai rumah aided by the Council of Elders in the longhouse so that any dispute can be settled amicably among the dwellers themselves via berandau (discussion). If no settlement can be reached at the longhouse chief level, then the dispute will escalate to a more senior leader in the region or pengulu (district chief) level in modern times and so on. Among the main sections of customary adat of the Iban Dayaks are as follows: (House building rule) (Marriage, adultery, and divorce rule) (Childbearing and raising rule) (Agricultural and land use rule) (Headhunting rule) and adapt ngintu anti Pala (head skull keeping) (Hunting, fishing, fruit and honey collection rule) (Widow/widower, mourning and soul separation rule) (festival rule) (Order of life in the longhouse rule) (Weaving, past times, dance and music rule) (Bird and
