Two fragments of flattish shafts, one of them apparently made of 
a bone of a sea mammal, each bearing one barb of this type, were found 
in heap D; a similar fragment was found in heap A. Four other fragments 
of harpoon heads having barbs of this style and a hole through the tang 
were found, three of them in heap A and one in heap L. All are flat 
with rounded backs and wedge-shaped tangs. Each has a hole gouged 
through the widest part of the tang near the barbed edge. Two of those 
from heap A show only one barb, but one of them is large and apparently 
had about four barbs. A third which is burned has two barbs and prob- 
ably had at least one more. The specimen from heap L certainly had 
two barbs, and probably had four. One large specimen from heap A 
shows the marrow canal on one side, and the base does not narrow or thin 
much. It had one barb, but the notch below it is so small that the tang 
does not seem to be an enlarged part of the shaft, and begins to taper 
far above the line hole. This hole is nearer the back than the barbed 
edge, was gouged, and tapers from each end as usual. Another from 
this heap is small, oval in section, had at least one barb, and is perforated 
as usual near the front edge of the tang, which tapers to a wedge-shaped 
base. A specimen found in heap D also had at least one barb from which 
the tang expands. The hole is through the widest part of the tang near 
the front edge, is gouged out, and tapers from each end. There are two 
incisions across one side of the tang below the hole and three across the 
other side. Two fragments of tangs show perforations of the usual kind. 
In one, a trough-shaped piece of bone rounded to a point, the hole is near 
the front edge. The other specimen is broken, so that it is impossible 
to determine the relative position of the line hole. 
A large tang (Plate VI, figure 13) is oval in section and had at least 
one barb, besides probably three or four on the missing end. It is slightly 
thinner at the barbed edge than at the back and has a peculiar, upturned 
projection or hook at the lower end of the notch under the barb. This 
tang is very long and tapers gradually. The hole through it is near the 
tip instead of at the widest part, and is nearer the front edge than the 
back. It is worn at the low T er end on both sides as if by a loop running 
through it. A tip of a harpoon (figure 14) had at least three barbs. It 
is oval in section and apparently made of part of a bone of a sea mammal. 
Another specimen (figure 16) has a knob at the end and one barb, 
and probably had three or four barbs when whole. Possibly it was used 
as one of the two outside prongs of a three-pronged fish-spear, and the 
knob may then have been intentional. On the other hand, the extreme 
tip and the first barb may have been accidentally broken off and the 
scars rounded, or it may be an unfinished pointed harpoon head, the barb 
shown being the first barb and the knob an unremoved part of the bone. 
The fragment of a large harpoon point made of antler (figure 17) 
has been so burned that it has a metallic ring. There is only one barb 
on this fragment, but the shape of the shaft, roughly triangular in section 
with sharp barbed edge, suggests that the harpoon head was barbed only 
on one edge. This edge of the barb does not project beyond the general 
outline of the object; in this respect differing from the type in figure 20. 
The notch under the barb was cut from both sides and the axil is rounded, 
as in those shown in figures 11, 18, and 20. This specimen is decorated, 
as described on page 85, by a longitudinal row of pits extending on the
