In the manufacture of baskets the woman makes use chiefly of bamboo and rattan, though other materials, such as _pandanus_ are sometimes brought into service. Three weaves or their variants are employed. The first is the common diagonal or twilled weave, in which each element of the weft passes over two or more of the warp elements. In this way most of the rice winnowers, transportation baskets, knife sheaths, and the like are made. In the second weave (Fig. 22), the foundation of the basket is made up of parallel horizontal rods, or strips of bamboo. These are laced together by warp strips which pass alternately under one and over one of the foundation rods, crossing each other at an angle, one above the other below the rod. The trinket baskets carried by the women, the larger waterproof receptacles known as _binota_, and the covers for wild chicken snares are in this technic. A variant of this weave is found in the rattan carrying frames and in some fish traps (Fig. 23). Here the warp strips cross one another at an angle, at each meeting place enclosing the horizontal foundation strips. Unlike the second weave described, the warp strips do not pass alternately above and below the horizontal foundation, but retain the same relation to it throughout the entire length of each strip. A coiled weave (Fig. 24) is used in the manufacture of tobacco boxes (Plate XIX) and in the rims of women's baskets. In this type the foundation consists of a series of horizontal rattan strips or rods which are sewed together in the following manner. A narrow strip _A_ passes over two of these parallel rods _2_ and _3_ in a left handed spiral. At the top of the loop the strip passes under a similar strip _B_ which binds rod _2_ to the one above. Passing downward inside the basket, the strip _A_ goes beneath the strip _C_ which binds rods _3_ and _4_ together. These are drawn tightly while damp, thus forcing the foundation rods so closely together as to make the basket practically water-tight. Pitch from the _tabon-tabon_ nuts may also be rubbed over the outside surface, thus making the receptacle impervious to water. FIG. 22. FIG. 23. FIG. 24. TYPES OF WEAVING USED IN BASKETRY. In the great majority of baskets the surface is divided into three parallel zones or decorative bands. These are produced by making a slight variation in the weave, by the use of blackened strips of bamboo and rattan, or by substituting in their place the black cuticle of a fern.
