Formerly these old beads were one of the principal forms of currency, and they still constitute an important part of the wealth of many families.

Most of these valuable old beads are of foreign manufacture, though a few made from shell and agate are of the country. The old foreign-made beads were probably imported by Arab and Chinese traders at various dates. Some of them are probably of Chinese manufacture, others probably came from the near East and even from Venice. Some are of glass curiously marked and coloured, others of stone inlaid with bits of different colours, others of some hard substance whose composition defies description. Certain rare kinds are especially valued and can hardly be bought at any price; they are reckoned to be worth at least 100 dollars apiece. The most valuable of all is known as the LUKUT SEKALA; the ownership of each such bead is as accurately known throughout a large district as the ownership of the masterpieces of ancient art in our own country. The wife of a rich chief may possess old beads to the value of thousands of pounds, and will wear a large part of them on any occasion of display (Pl. 130). These old beads are worn threaded together to form necklaces and girdles, being arranged with some reference to harmony of size and colour and to value, the most valuable being placed in the middle where they will be shown to best advantage. A single rare bead is sometimes worn on the wrist.

A woman who possesses a good stock of such beads will seldom be seen without some of them on her person. She will occasionally exchange a few for other varieties, and is generally eager to add to her collection; she may occasionally make a present of one or two to some highly esteemed friend or relative, and will generally assign them, but without handing them over, to various female relatives before her death.

Besides these valuable old beads there are in use among all the tribes many small glass beads of modern European manufacture. These are threaded to form a variety of designs, generally in two colours, the combination of black and yellow being the most commonly preferred. These strips of beadwork are put to many decorative uses: they are applied to the women's head-bands, to the centre of the sun-hat, to sword sheaths, to cigarette boxes, to the war-coat at the nape of the neck, and, by some Klemantans, to the jackets of the women.

The designs worked in this way are but few, and most of them are common to all the tribes. The thread used is prepared by rolling on the thigh fibres drawn from the leaf of the pine-apple; it is very strong and durable. The design to be reproduced is drawn or carved in low relief on a board. A thread is fixed across the end of the board and others are tied to it at short intervals; on these the beads are threaded, neighbouring threads being tied together at short intervals; and the colours of the beads are selected according to the demands of the pattern over which they are worked.

Besides these designs on the flat, tassels, girdles, necklaces, ear-rings, and cigarette rings are also made of these beads. The modern imported beads used for these purposes are sometimes improved by being ground flat on the two surfaces that adjoin their neighbours; this is done by fixing a number of them into the cut end of a piece of sugar-cane and rubbing this against a smooth stone. This treatment of the beads gives to the articles made of them a very neat and highly finished appearance.

Bamboo Decorations

The working of designs on the surface of pieces of bamboo is done very simply, but none the less effectively. Among the bamboo articles generally decorated in the way to be described are the native drinking-cup, the tobacco-box, and tubes for carrying flint and steel and all sorts of odds and ends.

The pattern to be produced is outlined with the point of the knife upon the surface of the bamboo, the artist working from memory of the desired pattern and adapting it to the proportions of the surface to be covered. The Iban works more freely than others, working out the pattern and modifying it to meet the exigencies of his material, section by section, as he goes along. Others plan out the design for the whole surface before working out any part in detail. It is probable that in no case does a man sit down and produce a new pattern; but the freer mode of working of the Iban leads him on to greater modifications of the traditional designs; and it is probably partly for this reason that a much larger variety of designs is applied in this way by them than by the other tribes, among whom they are very limited in number. But the greater variety of designs worked by the Ibans is due also to the readiness with which he copies and adopts as his own the patterns used by other tribes. The Kayans and Kenyahs use almost exclusively varieties of the dog pattern and of the hook and circle (see Fig. 47).

The design outlined by the point of the knife is made to stand out boldly from the ground by darkening the latter. This is achieved in two ways: (1) the ground is covered with parallel close-set scratches, not running continuously throughout the larger areas of the ground, but grouped in sets of parallel lines some few millimetres in length, the various sets meeting at angles of all degrees; (2) the hard surface of the bamboo is wholly scraped away from the ground areas to a depth of about half a millimetre. In either case the black or red paint is then smeared over the whole surface with the finger, and when it has become dried the surface is rubbed with a piece of cloth (Kayan), or scraped lightly with a knife (Iban). The pigment is thus removed from the intact parts and remains adherent to the lines and areas from which the hard surface layer has been removed. The design is thus left in very low relief, and is of the natural colour of the bamboo upon a black or dark-red ground, or on a ground merely darkened by the parallel scratches (Pls. 126, 127).
