When the weaver wishes the diagonal ridges to run upwards from right to left, she opens the sheds in regular order from below upwards thus: First, second, third, fourth, first, second, third, fourth, &c. When she wishes the ridges to trend in the contrary direction she opens the sheds in the inverse order. I found it convenient to take my illustrations of this mode of weaving from a girth. In Figs. 44 and 46 the mechanism is plainly shown. The lowest (first) shed is opened and the first set of healds drawn forward. The rings of the girth take the place of the beams of the loom.
There is a variety of diagonal weaving practiced by the Navajos which produces diamond figures; for this the mechanism is the same as that just described, except that the healds are arranged differently on the warp. The following diagram will explain this arrangement.

To make the most approved series of diamonds the sheds are opened twice in the direct order (i.e., from below upwards) and twice in the inverse order, thus: First, second, third, fourth, first, second, third, fourth, third, second, first, fourth, third, second, first, fourth, and so on. If this order is departed from the figures become irregular. If the weaver continues more than twice consecutively in either order, a row of V-shaped figures is formed, thus: VVVV. Plate XXXV represents a woman weaving a blanket of this pattern, and Fig. 48 shows a portion of a blanket which is part plain diagonal and part diamond.

§ VIII. I have heretofore spoken of the Navajo weavers always as of the feminine gender because the large majority of them are women. There are, however, a few men who practice the textile art, and among them are to found the best artisans in the tribe.
