of the wall of a large bone with a narrow canal so that, though gener- 
ally oval in section, it has a groove in the middle of one side. Another, 
more delicate specimen (Plate VI, figure 3), found in the same heap, 
was made of a piece of the wall of a small bone and has four barbs. It 
appears to have been a longer object that was broken obliquely and re- 
pointed, since a large part of the broken surface, showing on the reverse, 
has not been smoothed and the point is not as symmetrical as usual. 
The remaining four specimens found in heap A are basal ends of harpoons. 
One is sharp, like a point, and is almond-shaped in cross-section, with two 
barbs that point down at about 45 degrees and are well undercut; another 
is more wedge-shaped than pointed, although almond-shaped in section; 
the third has a wedge-shaped base and shows traces of the marrow canal; 
the fourth is large w r ith narrowed, wedge-shaped base. The specimen 
found in heap D lacks both ends; its barbed edge is sharp, and its back 
is rounded. 
The third type of barb is a combination of the first and second types 
of barbs (Plate VI, figures 4-8) and is seen on twelve specimens; eight 
of them being from heap A, one probably from heap B, two from the pre- 
historic cemetery, and one from heap M. 
One specimen (figure 5) is almond-shaped in cross-section and made 
of a thick, strong piece of bone. A point from the same heap has seven 
barbs cut into the sharp edge of a piece of the wall of a small long-bone that 
is rounded on the back edge (figure 6). The tang was narrowed, probably 
for insertion in a socket or in the split end of a shaft. 
It may be considered an intermediate form, the barbs of the fifth 
type being an enlargement and development of this type of barb. This 
point is made of a longitudinal piece of metapodial bone, apparently of 
a deer, cut out by grooving and breaking. The large and bulging joint 
end of the bone remains and, therefore, the point is not suited for inser- 
tion in a socket or the split end of a shaft; possibly it was left unfinished, 
since all other harpoon points and simple points have narrowed or wedge- 
shaped tangs. 
One specimen (figure 7) with six barbs very slightly notched on the 
two sides, has an unusually blunt point in comparsion with the long, slender 
tang, as if it had been broken off and re pointed. It is made of heavy 
bone and in cross-section is crudely almond-shaped. 
One harpoon point (figure 8) has four barbs. It is made of a section 
of a thick, large bone, rounded at the back edge and sharp on the front 
edge, so that it has an almond-shaped cross-section. A part of the marrow 
canal shows in the middle of the reverse. The base has not been evenly 
trimmed but apparently still follows the original shape of the piece of 
bone. The tip has been removed by incising and breaking, possibly 
because it had been broken. This incising shows more on the reverse than 
on the obverse. The specimen is unique among those from the harbour in 
being decorated, as mentioned under decorative art on page 85, with three 
parallel longitudinal grooves, each bearing short, diagonal grooves so as 
to resemble impressions made by a twisted cord. 
One very heavy tip of a harpoon point, with two notches, was found in 
heap A. It is made of a thick bone and is nearly flat on one side, the other 
showing two convex surfaces meeting in a medium ridge. Three more
