heap is apparently of identical material, and, being about the same length, 
may have been cut from the same original piece. It is roughly rectangular 
in cross-section and measures about f by j of an inch. It shows on one 
side an incised surface over about half the area, and a broken surface over 
the rest. There is a similar surface on the adjacent side. The next side 
is smoothed or scraped and bears an incision running in from the edge, 
apparently where the grooving was started to cut that edge. The last 
side is a cut surface. The two ends are smoothed. 
A piece of greenish sericite schist, about 1^ inches square and § inch 
thick, was found in heap A. One side is merely a broken surface which 
extends to the opposite side along one edge. The other side seems to have 
been cut to within about i inch of the edge and broken the rest of the way. 
This cut surface bears about a dozen incisions across the grain of the incising, 
and the broken surface has been slightly smoothed. An adjacent edge was 
also cut nearly off, then broken, and the broken surface smoothed, or 
possibly made by cutting off a probable projection caused by breaking. 
Two other edges are cut or ground nearly flat. 
Of specimens cut by this process more of bone than of stone were 
found, some cut longitudinally (Plate XVIII, figures 3-6), and one cut 
transversely (figure 9). A thin piece of bone (figure 3) has a longitudinal, 
incised groove near the middle of the lower half of the obverse side, but 
not opposite it on the reverse. Both top and bottom of the specimen 
are broken off and lacking, and the bone was broken off along the lower 
half of the part of the groove that remains. The right edge was cut off 
the entire length of the fragment by incising from the reverse side only 
and breaking. The breaking did not exactly follow the groove, as is 
shown by the ragged projection on the lower part of this edge. The left 
edge is sharpened by grinding. 
A piece of a comparatively thin-walled, long bone (figure 4) was 
partly cut out by longitudinal grooving from the outside nearly through 
on each of the two side edges and was then detached by breaking along 
these grooves. 
The piece of a metapodial bone of a moose (figure 5) shows longitudinal 
grooving on the front wall at the right and smoothing on the one at the 
left. It was no doubt partly cut out by grooving nearly through from 
the outside on both sides of the piece and then broken out along these 
grooves. In this case the grooved and broken edges were rubbed smooth, 
so that no signs of the grooving and breaking show except the grooving 
on the right, previously mentioned. One rear part of a metapodial bone 
of a moose (figure 6) shows where the natural bone was grooved nearly 
through on both sides and broken, apparently to get bone of suitable 
size for making such artifacts as harpoon points. 
Smaller pieces of cut and broken bones, but possibly of other animals, 
were frequently found in heap A. Five show longitudinal grooving on 
the outer surface of the bone and breaking through to the marrow canal 
on one edge, and three pieces, two being of large bones, show this on both 
edges. The grooved surface, on one of the last three, shows innumerable 
small, parallel, transverse striations, too regular to be caused by the gnawing 
of a small rodent. Another of these three, broken off short, is grooved in 
the middle, but not yet broken through. It is so shaped that if it had not
