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).
