The costume a Dyak wears when going on the war-path, consists of a basket-work cap, decorated with feathers, and sometimes with human hair, a sleeveless skin or cotton jacket, and the usual Dyak costume of the waistcloth. For weapons, he has a sword. This may be of foreign or of their own make. It is a dangerous weapon at close quarters. He also has a spear consisting of a long wooden shaft of some hard wood with a steel spear-head, which is tied on firmly to the shaft with cane. For defensive purposes the Dyak has a large wooden shield, about three feet long, which, with its handle, is hollowed out of a single block of wood. It is held in the left hand, well advanced before the body, and meant not so much to receive the spear-point, as to divert it by a twist of the hand. It is generally painted in bright colours, and often decorated with human hair. Sometimes the shaft of the spear is a _sumpit_ or blow-pipe. This is a small wooden tube about eight feet long. The smoothness and straightness of the bore is remarkable. The hole is drilled with an iron rod, one end of which is chisel-pointed, through a log of hard wood, which is afterwards pared down and rounded till it is about an inch in diameter. The dart used with the _sumpit_ is usually made of a thin splinter of the _nibong_ palm, stuck into a round piece of very light wood, so as to afford a surface for the breath to act upon. These darts are sharpened to a fine point, and are carried in neatly-carved bamboo quivers. The poison for these darts is obtained from the _ipoh_ tree (upas). Though the wound made by the dart is very slight, yet so potent and deadly is the poison, that death follows in a very short time. The Dyaks do not attack a village if their approach has been discovered, and the people are on the defensive. Under these circumstances, they content themselves with cutting off stragglers, or hide near the water-side for people who are going to bathe, or on their way to examine their fish-traps. These they attack unawares, cut down, take their heads, and escape into the jungle before the alarm is given. When fighting, the Dyak warriors gather round their chiefs and defend them bravely. Relatives often cluster together for mutual help. When one of them is killed, rather than allow the enemy to take his head, they decapitate him themselves, and bring his head back.
