The larger beads were perforated by drilling from both sides. They 

 also show a variety in OA'erall shape. In some, the height is equal to 

 the thickness and the sides are vertical. Others are thicker on one side 

 and thinner on the other, with vertical sides (fig, 46, Z> ) . In still others 

 the sides are of equal thickness but their sides bulge slightly, giving a 

 convex or "barrel-shaped" effect (fig, 46, c). The larger disk-shaped 

 beads vary in diameter from 7 mm. to 10 mm. and are usually ap- 

 proximately 4 mm. in height, as illustrated in figure 46, a and c. Then, 

 there is the wedge-shaped bead of the same diameter whose greatest 

 height may vary from 2 mm, to 4 mm., with the tapering end varying 

 from 1 mm. to 2 mm., as shown in figure 46, b.

Occurring in a common necklace were two roughly barrel-shaped 

 shell beads whose greatest thickness measured 13 mm. Both ends of 

 each taper in the same direction, creating a foreshortened or slightly 

 wedge-shaped effect. The minimum heights of each are 9 mm. and 

 10 mm. The smallest diameters, 6.5 mm. to 7 mm., occur at the ends 

 or abutting surfaces; the maximum diameters, 9 mm. to 10 mm., occur 

 at the center of the bead. 



Associated with this same necklace were two perforated elk's teeth 

 (pi. 73, &). The size of their perforations matched those of the other 

 beads. In contrast to the dull, heavily encrusted exteriors of the shell 

 beads, the elk's teeth still retained their high polish. This polish was 

 marred by small patches of a black substance which had penetrated 

 the enamel. At first, it was thought that these patches were specks 

 of graphite, since particles of graphite were present in the site in the 

 form of faceted nodules, but when the teeth were examined under a 

 microscope, it was determined that these darkened areas were partly 

 caused by a form of decomposition. 



Most of the larger barrel-shaped beads (fig. 46, e) are round in 

 cross section, but there are a number which are rectanguloid, being 

 rectangular but with rounded corners. All of these vary as to size. 

 Diameters vary from 6 mm. to 13 mm. ; heights from 9 mm. to 15 mm. 

 Other beads of this size tend to be spheroid. From the twist in the
