Besides these sun-hats, the Kayans and Kenyahs and some of the Klemantans weave with fine strips of rattan close-fitting skull-caps and head-bands. The ends of the strips, some three or four inches in length, are sometimes left projecting from the centre or forming a fringe round the lower edge.
The close-fitting hemispherical war-cap is made of rattans about half an inch thick split in halves.
The Making of the Blow-pipe
The blow-pipe or SUMPITAN is perhaps the finest product of native Bornean craftmanship. It is made by Kayans, Kenyahs, and Punans, and rarely by Ibans and Klemantans.
The best sumpitans are made from the hard straight-grained wood of the JAGANG tree. Having chosen and felled the tree, often one of large size, the craftsman splits from it long pieces about eight feet in length. Such a piece is shaved with the adze until it is roughly cylindrical and three to four inches in diameter (Pl. 112). The piece may be carried home to be worked at leisure, or the boring may be done upon the spot. A platform is erected about seven feet above the ground; and the prepared rod is fixed vertically with the upper end projecting through the platform, its lower end resting on the ground (Pl. 113). Its upper end is lashed to the platform, its lower end to a pair of stout poles lashed horizontally to trees, and its middle to another pair of poles similarly fixed.
The next operation, the boring of the wood, is accomplished by the aid of a straight rod of iron about nine feet long, of slightly smaller diameter than the bore desired for the pipe, and having one end chisel-shaped and sharpened. One man standing on the platform holds the iron rod vertically above the end of the wood, and brings its sharp chisel edge down upon the centre of the flat surface. Lifting the rod with both hands he repeats his blow again and again, slightly turning the rod at each blow. He is aided in keeping the rod truly vertical by two or three forked sticks fixed horizontally at different levels above the platform in such a way that the vertical rod slides up and down in the forks, which thus serve as guides. The rod soon bites its way into the wood. An assistant, squatting on the platform with a bark-bucket of water beside him, ladles water into the hole after every two or three strokes, and thus causes the chips to float out. This operation steadily pursued for about six hours completes the boring. In boring the lower part, the craftsman aims at producing a slight curvature of the tube by very slightly bending the pole and lashing it in the bent position; the pole on being released then straightens itself, and at the same time produces the desired slight curvature of the bore. This curvature is necessary in order to allow for the bending of the blow-pipe, when in use, by the weight of the spearblade which is lashed on bayonet-fashion. If the desired degree of curvature is not produced in this way, the wooden pipe, still in the rough state as regards its outer surface, is suspended horizontally on loops, and weights are hung upon the muzzle end until, on sighting through the bore, only a half circle of daylight is visible — this being the degree of curvature of the bore desired. The wood is then heated with torches, and on cooling retains the curvature thus impressed on it.
It only remains to whittle down the rough surface to a smooth cylinder slightly tapering towards the muzzle (Pl. 114), to polish the pipe inside and out, to lash on the spear-blade to the muzzle end with strips of rattan, and to attach a small wooden sight to the muzzle end opposite the spear-blade. The polishing of the bore is effected by working to and fro within it a long piece of closely fitting rattan; that of the outer surface, by rubbing it first with the skin of a stingray (which, although a marine fish, sometimes ascends to the upper reaches of the rivers), and afterwards with the leaf (EMPLAS) which is the local substitute for emery paper.
The shaft of the poisoned dart is made from the wood of the NIBONG and wild sago palms. It is about nine inches in length and one-sixteenth to one-eighth of an inch in diameter (Pl. 115). On to one end of this is fitted a small tapering cylinder of tough pith, about one inch in length, its greatest diameter at its butt end being exactly equal to the bore of the pipe. The pith is shaved to the required diameter by the aid of a small wooden cylinder of the standard size (Fig. 42); this is prolonged in a pin of the same diameter as the shaft of the dart. A piece of pith transfixed by the pin is shaved with a sharp knife until its surface is flush with that of the wooden gauge.
The poison is prepared from the sap of the IPOH tree, ANTIARIS TOXICARIA. The milky sap runs out when the bark is incised, and is collected in a bamboo cup (Pl. 88). It is then heated slowly over a fire in a trough made from the leaf stem of a palm, until it becomes a thick paste of dark purple brown colour (Pl. 116). When the poison is to be applied to the darts, it is worked into a thinner paste on a palette with a spatula. A circular groove is cut round the shaft of the dart about two inches from its tip, and the part so marked off is rolled in the paste and then dried before a fire. For use against large game, pig, deer, or human beings, a larger dose of poison is required than can be carried on the tip of the shaft. A small triangular piece of metal is affixed by splitting the tip of the shaft, thrusting in the base of the triangular plate, and securing it with a fine thread of rattan or fern-stem. The poison is then applied to the surface of this metal. The metal is obtained nowadays from imported tin or brass ware, but formerly a slip of hard wood was used, and, possibly, in some cases stone.
The quiver for carrying the darts is a section of bamboo about four inches in diameter and ten inches in length, fitted with a cap of the same which fits over the shaved lip of the main piece (Fig. 44). A wooden hook lashed to the quiver enables it to be hung from the belt. The darts, mostly without piths, are wrapped in a squirrel skin and thrust tip downwards into the quiver. A small gourd tied to the quiver carries a supply of piths all ready to be placed on the darts.
