23 
raw material; and seven are cores from which pieces had been chipped. 
Fifteen are large chips of metargillite, and forty-five are large and small 
chips (Plate III, figures 5 and 6). Nine are chipped pieces; twenty-two, 
three of which are illustrated on Plate III, figures 7, 8, 12, are rejects; 
one is a point broken in process of chipping; one is a thick, leaf-shaped 
point, probably a reject; and one is a point with the butt unfinished. 
It is noteworthy that there are only one hundred and seven specimens 
in process of manufacture from metargillite as compared with one hundred 
and twenty-two finished products from the same material. This may 
mean that the prehistoric people quarried the metargillite and partly 
chipped most of it at or near the quarries; most of the chips and rejects 
would then remain at the quarries, and chiefly the chips of the finishing 
process would be left at the sites on the harbour. 
The manufacture of points chipped from quartz and quartzite is 
illustrated by over one hundred and one specimens. Among these are: 
some white quartzite pebbles, that may have been raw material for points 
or scrapers; a fragment of a pebble; and a longitudinal sector chipped 
from a small pebble. Seventy-four specimens are pebbles or chips from 
such pebbles (Plate III, figure 2) showing one or two battered poles from 
which the chips were struck (Plate III, figure 3); most of the pebbles 
were small, but a few were large (Plate III, figure 1) and from them a 
piece or pieces had been chipped until in many examples more than half 
of the pebble was gone. The remaining specimens include: eleven chipped 
pieces (Plate III, figure 4); three small chips; a chip of a light grey 
quartzite pebble; a chip of clear quartz; three pieces chipped and apparently 
rejected; a leaf-shaped point or reject chipped from quartzite (Plate III, 
figure 11); a lozenge-shaped object chipped from quartzite (Plate III, 
figure 14); a reject chipped from quartz with the base broken off and 
missing; a fragment of a reject bearing a barb; a thick, coarse reject 
with the point missing; and a crude, triangular point. 
Of finished products of quartz and quartzite there are only: a tanged 
quartz point (Plate IV, figure 12); two broken, barbed points made of 
quartz; two tanged points of quartzite (Plate IV, figures 7 and 13), the 
one in figure 7 with the point shorter than the tang; a butt broken from a 
notched and barbed point of grey quartzite; and twelve scrapers chipped 
from white quartzite (Plate XVII, figure 2). 
Altogether there are, in addition to some unbroken quartz pebbles, 
eighty-seven pieces of quartz pebbles, five chips, and nine rejects or crude 
points; a total of one hundred and one articles in process of manufacture 
from quartz and quartzite; whereas there are only five specimens of finished 
points or, counting the twelve scrapers chipped out of white quartzite 
pebbles discussed on page 62, a total of seventeen finished articles. Thus 
in the case of quartz and quartzite there are more specimens of materials 
in process of manufacture than of finished products, which is the converse 
of the case with respect to metargillite. 
Three specimens of chalcedony were found. Two are chips, and the 
third is a leaf-shaped piece (Plate III, figure 13). 
Three specimens of jasper were found. Two are chips of yellow 
jasper, and may have resulted from making either points or scrapers; 
the third is a reject in the manufacture of a point. Eight scrapers chipped 
from jasper were found and are discussed on page 62.
