the H-like figures in the central stripe being quite unusual and 

 unexplained. Another variant is that in Figs. 2, 5 (Plumas 

 County), here- associated with the quail-tip design, which 

 forms the triangular figure in the centre about the rim. The 

 pack-basket, Fig. 3 (Plumas County), shows a simple form of 

 the design more like those on Plate X; and Fig. 4 (Plumas 

 County) presents still a fifth type of the design, with an 

 irregular figure of unknown significance inside the "point." 



Without doubt the most frequently used of all designs is 

 the arrow-point or flint. Throughout the whole Maidu area 

 this design seems to predominate, and while varying in a 

 number of ways, yet it is almost always easy to recognize. 

 A rather common form of the design in the south is that on 

 Plate XII, Fig. i (Placer County). Another type occurs in 

 Fig. 2 (Plumas County). Here in this Northern Type the 

 arrow-points are doubled, being placed base to base. In Fig. 

 3 (El Dorado County) is another and simpler treatment, and 

 in Fig. 4 (Butte County) a rather striking arrangement in 

 spirals. In all these cases the design seems to be differen 

 tiated from the simpler forms of the feather by the fact that 

 the triangles are typically isosceles and have their bases or 

 shortest sides horizontal, whereas the triangles in the feather 

 design are rarely isosceles, and have their bases or shortest 

 sides vertical or oblique. A simple form recalling Plate XII, 

 Fig. 2, is that on Plate XIII, Fig. i (Plumas County). Here 

 the points are placed base to base as in the other design, but 

 actually in contact, and are linked as before by narrow lines. 

 Plate XIII, Fig. 2 (El Dorado County), shows a very pleasing 

 symmetrical arrangement of these double points standing 

 singly, and is also remarkable as being one of the two ex 

 amples, out of many hundreds of baskets seen, in which the 

 groundwork of the design is dark; all others, without excep 

 tion, having dark designs on a light background. Another 

 symmetrical treatment occurs again in Fig. 3 (Butte County), 

 and serves apparently as a transitional form to the simple 

 zigzag in Fig. 4 (El Dorado County), which is one of the 

 common forms of the arrow-point in this region. A very odd 

 design occurs on the plaque-basket in Fig. 5 (Plumas County),
