the corners of the back edge and the front edge. These are in one edge 
on the sharp part, and on two corners on the undercut, below the barbs, 
that is, one on each corner of the undercut. A longitudinal row of small 
pits may be seen on one of the two smooth sides of a fragment of burned 
bone nearly square in cross-section, Cat. No. VIII-B-687, found in the 
prehistoric cemetery. Three parallel, longitudinal grooves, each bearing 
minute, slightly oblique cross-grooves, making them resemble impressions 
of twisted cord, extending about half the length of the object, may be seen in 
the middle of one side of the harpoon point made of bone (Plate VI, figure 8). 
A longitudinal row of pits may be seen on the back edge of a fragment of 
a large harpoon point made of bone or antler (Plate VI, figure 17). This 
row extends over half the length of the fragment; in the other half it is 
replaced by a groove. A row of pits bounds the front edge and the notch 
under the barb on the smoother side, being the outer side of the bone or 
antler; another row slightly farther from the edge bounds the back edge. 
A longitudinal row of large pits or gouge depressions and a longitudinal 
groove may be seen on the back edge of a fragment of an antler harpoon 
point, from the same place, Cat. No. VIII-B-679. The groove may be 
the trace of grooving made in cutting out the harpoon. Pits impressed 
in rows on pottery, apparently with a stylus-like tool, are illustrated on 
Plate X, figures 2-4, 12, 13, and Plate XI, figures 7, 8. A row of vertical 
slits or gashes made in the neck of a pot before the ware was fired is illus- 
trated on Plate X, figure 2. 
Much impressing upon pottery was done before the ware was fired. 
The impressions are apparently confined to the rim and upper part of the 
pots, as none of the fragments supposedly of the lower part bears any decora- 
tion. Some of this impressing was apparently done with simple stylus- 
like tools (Plate X, figures 2-9, 12, 13). These impressions take the form 
of lines in some specimens (figures 2-4, 6, 8, 9). Scallops were impressed 
in the upper edge of the rim of one pot, as is shown by a fragment (Plate 
X, figure 11). Though impressions of the finger tips were not seen on any 
of the ware, there are impressions of the nails on a single fragment from 
heap K (Plate IX, figure 8). No impressions of paddles carved in checkers 
or otherwise were seen, nor of paddles wrapped with cord or netting. 
Pits impressed in rows may be seen on a few specimens (Plate X, figures 
2, 12, 13, and Plate XI, figures 3, 7, 8). About a tenth of the 
fragments bear decorations impressed with a rocking stamp. One of 
these fragments (Plate X, figure 22) bears a zigzag, apparently impressed 
with a knife-edged stamp. Some of the fragments bear parallel lines 
(Plate X, figures 14, 16-18), others zigzag lines (Plate X, figures 1, 19-21, 
23), ail made with a rocking stamp. Parts of these lines are made with a 
rocking stamp making rows of square depressions, each alternate square 
being impressed deeper than its neighbour (Plate X, figures, 14, 15, 17, 20, 
21), others, also made with a rocking stamp, making rows of triangular 
depressions on the sides of the lines, those on one side being impressed 
deeper than those on the other (Plate X, figures 1, 12, 16-19, 23), 
Impressions, apparently made with a twisted cord (Plate XI, figure 7), 
may be seen on many of the fragments. Rows of nearly transverse, parallel 
impressions of twisted cord, apparently applied by impressing with a twig 
wound with twisted cord (Plate XI, figures 1-10), may be seen on other
