HARRINGTON] DESCRIPTION OF THE ARTIFACTS 109 
The beveling to the flat side starts 8 mm. from the end. Only part of the 
specimen is shown in the plate. (PI. 19, b, 8.) 
Tip fragment of sea-lion rib implement, 48 mm. long, § mm. wide, 7 mm. 
thick. The beveling to the flat side starts 9 mm. from the tip and exposes the 
interior hollow of the rib, which is very straight. 
SEA-LION RADIT 
Altogether nine of these bones were found in the graves, all but 
one tip fragments, and none of them showing signs of having been 
used. The sturdiness of the bone and the hardness of the point 
would suggest that they would make good flakers for chipping flint. 
A sea-lion radius is figured by Putnam.’ 
Entire unworked California sea-lion radius bone possibly used as an imple- 
ment. 131 mm. long, 36 mm. wide, 23 mm. thick. The only entire specimen 
obtained. (PI. 19, b, 9.) 
BROAD BONE POINTS, WEDGE-SHAPED BONE IMPLEMENTS 
Tip fragment of bone point, 47 mm. long, 9 mm. wide, 4 mm. thick. Edges 
rounded. Inside surface has a deep furrow in its lower half. The extreme 
tip is broken off. 
Central fragment of bone point, 44 mm. long, 9 mm. wide, 4 mm. thick. The 
inside surface is much troughed. Edges rounded. The tip is broken off, leaving 
a stub 3.5 mm. wide, 3 mm. thick. 
Tip fragment of bone point, 35 mm. long, 12 mm. wide, 5 mm. thick. Inside 
surface much troughed. Edges rounded. Extreme tip broken off. 
Tip fragment of bone point, 37.5 mm. long, 8.5 mm. wide, 4.5 mm. thick. 
White all through, though the surface is whiter. Edges rounded. 
Central fragment of bone point, 49 mm. long, 10 mm. wide, 5 mm. thick. 
Left edge rounded, right edge squared. Stout enough to have been an awl. 
Tip fragment of bone point. Inside surface consists of a deep furrow, the 
only place worked being the edges of this furrow and the extreme tip; 52 
mm. long, 11 mm. wide, 9 mm, thick. Very strong. Can be classed as an awl 
fragment. 
Tip fragment of bone point, possibly to be regarded as entire bone awl, the 
butt of which was originally a fracture. Inside surface furrowed, 65 mm. 
long, 2 mm. wide, 4 mm. thick. Edges squared but become quite right rounding 
20 mm. from the tip, while the awl becomes round in section 10 mm. from 
the tip. 
Tip fragment of bone point, 36 mm. long, 9 mm. wide, 3.75 mm. thick. The 
inside surface has a large furrow. Edges rounded. A fracture extends 12 mm. 
up the right edge. 
Central fragment of bone point, 43 mm. long, 7 mm. diameter. Edges 
rounded. The specimen has no taper. 
Tip fragment of bone point, 28 mm. long, 9 mm. wide, 5 mm. thick. The 
surface of the inside is somewhat spongy. Edges rounded. 
Tip fragment of bone point, 24 mm. long, 9 mm. wide, 4 mm. thick, Extreme 
tip broken off. The inside surface consists largely of the natural furrow.
