The legs begin at the bottom of the apron from which they are set off by two horizontal incisions. The apron at the outline of the object projects slightly beyond them. On each leg are five incised isosceles triangles,--three at the top and two at the bottom, with their long points extending towards the knees. At each side of the lower triangles is one line which seems to represent a continuation of the designs around the legs. On each triangle are horizontal hachure. On both knees are faint traces of two concentric incisions, forming figures with rounded corners and bulging sides. Between these are radiating hachure. Close inside is a concentric incised line and there may be seen two parallel lines, nearly horizontal, above the right knee and one below it, and one above the left knee. The triangles may be considered as pointing from these concentric designs rather than towards them, and in that case the lines, suggesting the continuation of the design around the leg, appear at the top instead of the bottom. It does not seem probable that these triangles represent part of a circular design radiating from the knees, the sides of which are folded around the legs, but rather that the two series of triangles extend horizontally. The incisions on the legs probably represent painting or tattooing, since the designs seem to be horizontal and to extend all around the legs, while on leggings the patterns are usually vertical and on a flap at the outer side of the leg, the knee being disregarded. Catlin[295] figures paintings on the arms and legs of the Mandan similar to the patterns on this carving. The custom is not rare, especially in connection with elaborate ceremonial costumes such as are no doubt represented by this figure. The vertical incisions on the feet probably represent the toes, or designs painted or tattooed on the feet. These lines argue against any idea that the feet are encased in moccasins, unless bead or quill work on, or improbable wrinkles in, the moccasins are indicated by them. Porcupine quills, embroidery, beadwork and painting on moccasins were used in the general plateau region of which this is a part.[296] [295] Catlin, Plates V and VI. [296] Lewis, p. 190. Lewis suggests[297] that the tribes depending largely on the hunt, would be better supplied with skins for clothing than those subsisting generally on fish, and that in most of the plateau region, the scanty vegetation makes clothing from plant materials difficult, if not practically out of the question. In this connection, it will be remembered that this carving of antler which gives us our general archaeological information regarding ancient costume, comes from the higher or hunting region of the valley. It will also be remembered that sage brush and other plant materials were used for clothing in the Thompson River region to the north, where the vegetation is nearly as scanty as in the Yakima Valley.
