30 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I26 



loid in outline and planoconvex in cross section (pi. 3, 1^-2^). The 

 ventral surface invariably consists of the unmodified flake surface, 

 while the dorsal surface is ordinarily chipped to the extent necessary 

 to achieve the desired triangular shape. The steep, carefully chipped 

 working edge is alw^ays convex. The specimens vary in length from 

 18 to 30 mm. and in width from 19 to 26 mm. A planoconvex object 

 perhaps related to these implements is an oval with the two opposite 

 edges chipped to resemble the working edge of an end scraper 



(pl. 3, ^4)' 



Other chipped objects in addition to retouched flakes are an asym- 

 metrical, unifacially worked point of flint (pl. 3, 13), a small bi- 

 facially worked blade of quartzite (pl. 3, 26), and a flake with two 

 notches chipped into two of its three edges (pl. 3, 2^). 



Awls are the most numerous of the bone artifacts. Of the com- 

 plete specimens, three are made from the split proximal ends of deer 

 or antelope metapodials (pl. 4, p, 10, 13), one is from part of the 

 axillary border and adjacent portion of a scapula, possibly of deer 

 (pl. 4, 8), and one is from a rough fragment of the lateral surface 

 of a bison rib with the cancellous bone unmodified (pl. 4, 4). All 

 but the last of these have sharp, slender points. Of the two frag- 

 mentary specimens, one is a segment, squarish in cross section, of a 

 long bone (pl. 4, 11), and the other is from a split rib with the can- 

 cellous bone partially removed (pl. 4, 7). Three blunt-pointed objects 

 are splinters of long bones which have been worked only at and near 

 the tips (pl. 4, /, 3, 12). The single shaft straightener in the collec- 

 tion is a section of rib bearing a complete perforation and the remains 

 of another at each of the broken ends (pl. 4, 2). Each edge of the 

 rib bears two groups of 5 to 7 narrow, shallow, transverse notches. 

 Two incomplete specimens made from split ribs have rounded ends 

 and smoothed edges (pl. 4, 5, 6). In both instances, the cancellous 

 bone has been partially removed. On two fragments of rib, probably 

 of bison, the mesial surface was broken away near one end and the 

 remaining lateral surface was worked to a blunt point (pl. 4, 15, 16). 

 The remaining artifact of this material is a small, highly polished 

 tubular bead of bird bone. 



Of exotic material, there is a single specimen from the lower level 

 of this site, a shell, Olivella (Callianax) biplicata Sowerby, with 

 provenience on the Pacific coast, which has been altered by a large 

 break through the wall away from the natural opening. The borders 

 of the break are well polished, as is the exterior surface of the shell 

 in general, and so there is no question that the specimen was used 

 subsequent to the breakage (pl. 5, a, 7),
