The bows of all these instruments bear a strong resemblance to each other, as is only to be expected where all are of the simplest description. In the majority of cases the bow is merely a length of cane with a bunch of horse-hair tied at each end in such a manner as to pull the cane into a more or less pronounced curve. Those of the Goudok and Sarìndâ (Fig. 10) are short, approach nearly to a semi-circle, and are quite rigid.
Those of the Ravanastron, Omerti, etc., are longer, and being more slender, have a certain amount of flexibility, but it does not appear that this latter qualification is sought for or considered indispensable. On the other hand, the now nearly obsolete Kokiu of Japan had a bow of about forty-five inches in length that was extremely elastic. It was made in sections after the manner of a fishing-rod, and the hair was tightened by the finger of the player, as in some of the early viol bows of Europe.
The method of hairing in most cases amounts to the simplest way of tying the hair on to the stick. Sometimes the hair is passed through a slit and held in place by a knot. In other specimens it is attached to a leather thong, and occasionally it is plugged into the open end of a piece of bamboo (Fig. 11).

The bows of the Saw-tai (Fig. 12), Uh-Ch'in, Koka and a few others show a distinct advance in point of curve and adjustment of hair, and strongly resemble the bow of the quaint Swedish Nyckelharpa in present use (Fig. 13).
