Hose and Haddon have introduced the term _Klemantan_ (_Kalamantan_) for the weak agricultural tribes such as the _Murut_, _Kalabit_, _Land Dayak_, _Sebop_, _Barawan_, _Milanau_, etc.[519] Brook Low[520], who knew the Land Dayak well, gives a very favourable account of the people and this opinion has been confirmed by other travellers. They are described as amiable, honest, grateful, moral and hospitable. Crimes of violence, other than head-hunting, are unknown. The circular _panga_ is a "house set apart for the residence of young unmarried men, in which the trophy-heads are kept, and here also all ceremonial receptions take place[521]." The _baloi_ of the Ot Danom of the Kahajan river is very similar[522]. The very energetic and dominating _Bahau-Kenyah-Kayan_ group are rather short in stature, with slightly broad heads. They occupy the best tracts of land which lie in the undulating hills at the upper reaches of the rivers, between the swampy low country and the mountains. The Kayan more especially have almost exterminated some of the smaller tribes. The Klemantan and Kenyah-Kayan tribes are agriculturalists. They clear the jungle off the low hills that flank the tributaries of the larger rivers, but always leave a few scattered trees standing; irrigation is attempted by the Kalabits only, as _padi_ rice is grown like any other cereals on dry ground; swamp _padi_ is also grown on the low land. In their gardens they grow yams, pumpkins, sugar cane, bananas, and sometimes coconuts and other produce. They hunt all land animals that serve as food, and fish, usually with nets, in the rivers, or spear those fish that have been stupefied with _tuba_; river prawns are also a favourite article of diet. They all live in long communal houses which are situated on the banks of the rivers. Among the Klemantan tribes the headman has not much influence, unless he is a man of exceptional power and energy, but among the larger tribes and especially among the Kayan and Kenyah the headmen are the real chiefs and exercise undisputed sway. The Kenyah are perhaps the most advanced in social evolution, holding their own by superior solidarity and intelligence against the turbulent Kayan. All the agricultural tribes are artistic, but in varying degrees; they are also musical and sing delightful chorus songs. In some tribes the ends of the beams of the houses are carved to represent various animals, in some the verandah is decorated with boldly carved planks, or with painted boards and doors. The bamboo receptacles carved in low relief, the bone handles of their swords and the minor articles of daily life, are decorated in a way that reveals the true artistic spirit. Both Kenyah and Kayan smelt iron and make spear heads and sword blades, the former being especially noted for their good steel. The forge with two bellows is the form widely spread in Malaysia.
