The second type of weaving, also of cedar bark, is begun like the last mat, but the elements are so placed as to cross the sur face diagonally alternate strips passing diagonally downward to the right and left as in Figure 3. These strips are not woven but plaited over and under each other without the addition of a weft element as in weaving. When the side edge is reached the strips turn over at right angles and continue to plait in thechanged oblique direction. The lower edges are finished by bending the elements at right angles and plaiting them obliquely back for an inch into the completed surface. Checked weaving and plaiting is employed in a variety of ways, for aside from mattings it cnter'into the construction of baskets, pouches, bags.
