Their arms consist of the blow-pipe (sum-pi-tan), from which they eject small arrows, poisoned with the juice of the upas; a long sharp knife, termed pa-rang; a spear, and a shield. 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. Their warfare is carried on more by treachery and stratagem than open fighting--they are all warriors, and seldom at peace. The powerful tribes which reside on the banks of the river generally possess several war prahus, capable of holding from twenty to thirty men, and mounting a brass gun (leila) on her bows, carrying a ball of one to two pounds weight. These prahus, when an expedition is to be made against a neighbouring tribe, are manned by the warriors, one or two of the most consequential men being stationed in each prahu. Before they start upon an expedition, like the North American Indians, they perform their war dance. [Illustration: SAGHAI DYAK. (S. E. COAST OF BORNEO.) F. M. DELT. M. N. HANHART LITH. PRINTERS LONDON; LONGMAN & CO. 1848] Should their enemies have gained intelligence of the meditated attack, they take the precaution of sending away their women, children, and furniture, into the jungle, and place men in ambush on the banks of the river, who attack the assailants as they advance. The Dyaks are all very brave, and fight desperately, yelling during the combat like the American Indians. The great object in their combats is to obtain as many of the heads of the party opposed as possible; and if they succeed in their surprise of the town or village, the heads of the women and children are equally carried off as trophies. But there is great difficulty in obtaining a head, for the moment that a man falls every effort is made by his own party to carry off the body, and prevent the enemy from obtaining such a trophy. If the attacking party are completely victorious, they finish their work of destruction by setting fire to all the houses, and cutting down all the cocoa-nut trees; after which they return home in triumph with their spoil. As soon as they arrive another war dance is performed; and after making very merry, they deposit the heads which they have obtained in the head-house. Now, putting scalps for heads, the reader will perceive that their customs are nearly those of the American Indians. Every Dyak village has its head-house: it is generally the hall of audience as well. The interior is decorated with heads piled up in pyramids to the roof: of course the greater the number of heads the more celebrated they are as warriors. [Illustration: DYAK VILLAGE.]
