fragments of harpoon points were found in the same heap. One of them 
has a roughly almond-shaped cross-section and was whittled to a slender, 
acute point. The opposite end has been incised across to facilitate break- 
ing, or perhaps, to smooth the broken surface. A point, probably from 
heap B, has four barbs, and shows the marrow canal on one side, being 
made of a strip cut from a large bone. The lower end is broken off, but is 
the widest part of the object. A specimen of a tip (figure 15) broken from 
a very bluntly pointed harpoon head was probably dulled or broken off 
by use or accident. 
The fourth type of barb, made by notching a longitudinal ridge on 
the shaft or by removing parts of the edge between the barbs by long cuts, 
is seen on seven specimens. Three of them are from heap A, three from 
the prehistoric cemetery, and one from heap M. A long, slender harpoon 
point without tip, seen on Plate VI, figure 9, has barbs of this type. It is 
now 7^ inches long and, judging by its general outline, must have been 
at least 9 inches long. It is the longest point found on the harbour. 
There are three barbs at the base of the head, two near the middle, and 
two, one of them very slight, near the base. It resembles in a general 
way the special simple point made of bone, from the same heap, illustrated 
on Plate V, figure 15. Both have an enlarged lanceolate head with lenti- 
cular cross-section. The widest part of the shaft is oval and the lower 
part is nearly circular in cross-section, and tapers gradually to the base, 
the tip of which is missing. On one side the sharp edge of the head ends 
abruptly where the shaft expands to meet it. On the other side the sharp 
edge apparently extended to the base and by cutting way parts of it the 
barbs were left projecting. The undercut of each barb is slight. The 
three upper barbs are so close together that the cut edge, or the outer 
edge of the barbs, reaches from the tip of one barb to the base of the other. 
The shaft has been broken in two just below the upper group of barbs and 
the two parts subjected to different conditions. A red stained spiral band 
may be seen from the break to near the base. Apparently the base fitted 
into a socket which kept it from being stained. If the top piece was 
stained, the stain has disappeared, but possibly the staining was applied 
only to the lower part after the shaft was broken. This colouring is 
further discussed on page 83. 
A basal fragment of a harpoon head found in heap A is circular in 
cross-section and tapers to the base. It has a narrow, longitudinal ridge 
showing the grooving on each side by means of which it was formed. This 
ridge is notched, thus producing barbs like saw teeth and with no under- 
cut. Another specimen from the same heap is a part of a shaft in cross- 
section, with one longitudinal ridge-like projection, possibly a barb, which 
at one end rises suddenly at right angles to the shaft, and at the other 
end slopes to the shaft. There are two shallow transverse notches 
above the barb. A specimen from heap M is a section of a cylindrical 
shaft with a longitudinal ridge produced by a groove on each side. On this 
ridge a barb has been made by a cross notch. The longitudinal ridge on 
either side of the grooves that produced the barbed ridge has been partly 
cut away, but much farther below the notch than above it. 
A long, basal fragment of a harpoon point made of ivory with a notched 
ridge on one side, is catalogued under No. 203 in the Patterson collection 
as from a mussel bed in the harbour. It is 4f inches long by about 3f inches
