FLINT IMPLEMENT WITH ONE EDGE COARSELY TOOTHED 
Just one specimen was recovered, but a typical one, of the imple- 
ments coarsely toothed along one edge but having the other edge 
rounding, such as are figured by Wilson from San Miguel Island, 
Plate 40, Nos. 8, 11, and 14. These implements resemble a leaf- 
shaped arrowhead with a few roundish bits taken out of one side. 
Our specimen is of the typical whitish flint (chert) of which many 
of the arrowheads are made and comes from the screenings of Pit z. 
It represents a definite type of artifact but of unknown application. 
35 mm. long, 14 mm. wide, 6 mm. thick. (PI. 17, w.) 
SANDSTONE REAMERS 
Two easily identified reamers were found, both of the well-known 
type. 
Reamer of coarse and gritty gray sandstone, 39 mm. long, 20 mm. diameter 
11 mm. diameter at point. The point is blunt and rounding, and its neck 
shows abrasion from use as a reamer for enlarging bored holes. (Pl. 17, 8.) 
Reamer of coarse gray sandstone, 40 mm. long, 16 mm. diameter, 8 mm. diame- 
ter at the tip. The neck shows abrasion from use aS a reamer. (Pl. 17, t.) 
SLATE POINTS 
Slender and carefully shaped points of the rather fragile grayish 
slate rock that occurs in the region may have been used as arrow- 
heads. The specimens vary in size and in having bases either 
rounded or squared. 
Entire slate point. Gray. 42 mm. long, 6 mm. wide, 4.5 mm. thick. Beth 
ends sharp. 
Entire slate point. Gray. 45 mm. long, 11 mm. wide, 6 mm. thick. Truncate 
base.
