have step-like offsets on one edge. More particularly, these comprise five 
large sandstone specimens, four of which are dome-shaped fragments of con- 
cretions; small specimens made of pebbles having a gritty character; frag- 
ments of slabs of sandstone; and irregular pieces of sandstone. Some of 
each class are rubbed on one side, others on both. 
These whetstones were probably used for shaping, smoothing, and 
sharpening: stone celts; animal bones; pieces of bone that were to be used 
for points, harpoon heads, awls, and needles; pieces of bone, and of antler 
and beaver, and woodchuck teeth for wedges and similar purposes. 
These whetstones were evidently for shaping and sharpening various 
tools. They were probably used for smoothing and sharpening stone 
celts, animal bones, and pieces of bone that were to be used for points, 
harpoon heads, awls, and needles, pieces of bone and antler for wedges, 
beaver, woodchuck, and for similar purposes. 
One of the five large stones apparently used for grinding was found 
in heap A, three in heap D, and one in heap M. One is of sandstone, 
and four are dome-shaped fragments of large sandstone concretions such 
as are found along some of the beaches of the harbour. One of these 
(Plate XV, figure 1) is of sandstone. It is the larger fragment of a broken 
object that had a shallow, smooth, longitudinal hollow over practically 
all one side, apparently made by sharpening or grinding upon it. The 
fragment of a sandstone pebble found in heap M is about 8 inches across 
and is rubbed on one side as if from grinding objects into shape upon it. 
The surface, being smoothed over rather than ground down to one large 
plane, suggests that only small objects that would ride over the uneven- 
nesses were rubbed upon it. A fragment of a sandstone concretion 9 
inches in diameter, found in heap A, was not apparently purposely chipped, 
and is rubbed in one place on the convex side and to a nearly flat surface 
on the whole of the other side. One fragment of a large sandstone con- 
cretion about 9 inches in diameter, found in heap D, is roughly chipped 
around the edge and is rubbed on both sides. On the concave side the most 
rubbed surfaces are large and smooth, as if caused by sharpening celts 
upon them. The other specimen of a sandstone concretion, found in 
heap D, a somewhat similar fragment 7| inches across, was much weathered 
before being rubbed. It was apparently not purposely chipped and is 
rubbed only in places on the two sides. 
Of the rubbed pebbles, eight are from heap A, five from heap D, and 
one from heap L. Eight are whetted on one side, six on both. One from 
heap A is an angular, waterworn pebble 4^ inches long by 1^ inches in 
cross-section, whetted on one side; another is a flat, plummet-shaped 
pebble 3| inches long, whetted on one side. Ends of two sandy argillite 
pebbles less than 1 inch thick, over 4 inches long, and nearly 1^ inches 
wide, and a whole gritty pebble of similar size, all three found in heap D, 
are slightly whetted on one side. An irregular, broken pebble, a little over 
l inch thick and about 2 by 4 inches, found in heap A, is very slightly whet- 
ted on one side. A fragment of a long, oval pebble of schistose slate, found 
in shell-heap L, was used on one side as a whetstone. A pebble from 
heap A, 1 inch by 1^ inches in section, lacking both ends, is rubbed on two 
sides and an edge. A whetstone found in heap A, of about the same size 
as the one illustrated on Plate XV, figure 3, is a fragment of a similar
