Their arms are the kris and spear; occasionally they carry the sum-pi-tan, and poisoned arrows. Their houses are built upon stakes, probably for the sake of cleanliness; as the flooring consists of a kind of grating made of rattan, all dirt falls through. The houses are small, and contain but one family, and, like those of the Dyaks, are built of the lightest materials.
The invariable custom of filing the teeth sharp, combined with the use of the betel-nut turning them quite black, gives their profile a very strange appearance. Sometimes they render their teeth concave by filing. They are seldom without their arms, for the spear is used in hunting, the knife for cutting leaves, and the sum-pi-tan for shooting small birds.
