In figures 13, 15, 145 _a_ and 146 the rectangles are all placed in the same direction; the long side parallel to the short side of the hide. Fig. 145 _a_ consists throughout of curved segments corresponding to the obtuse triangles. At the apices of these segments the rectangles are divided by central lines. The fields separating the rectangles bear each an acute triangle with prolonged apex. In the narrow central field we find also the acute triangle with extending lines. Fig. 15 consists of the acute triangle with the usual frame but with scolloped edges instead of the angular figures of fig. 145 _b_. The central field is treated in the same way as in fig. 145 _a_. Fig. 13 corresponds nearly to fig. 145 _a_, except that the rectangular fields are not divided by a central line, but have a central figure somewhat hour-glass shaped enclosing an acute triangle at each end. The crosses in the middle field are also derived from the acute triangles. The three central fields of the long side of fig. 146 _b_ correspond to fig. 144 _a_. Since the rectangles in the marginal field on the short side are not turned, the acute triangle design did not fit and we find, therefore, instead the cross design. The lack of symmetry between the extreme upper and lower fields is quite unusual. In fig. 146 _a_ we find, as in fig. 14, only four fields. The designs are similar in character to those of fig. 146 _b_, except that the acute triangle design is developed in a peculiar manner. [Illustration: Fig. 147. Painted rawhide, Ioway.] The Ojibwa and Ioway use another method of building up their boxes. The short sides are made of separate flaps and there is no flap covering the front. The bottom is not decorated and the hide is folded over simply in box form and sewed together (fig. 147). The method used by the Otoe and sometimes by the Ioway, is still different. There is a short flap covering part of the front; the sides are folded in, somewhat in the same manner as done by the Fox and there is also a complete lack of coherence between the design as laid out on the hide and as it appears in the completed box (fig. 148).
