B. PECKED, GROUND AND POLISHED STONE. 
Wedges or Celts—These are numerously and well repre- 
sented in our collection. There are about fifteen examples. 
With few exceptions I consider that these have been hafted, and 
used as adzes. Specimens from the Rocky Mountain collection 
of Col. W. Chearnley, from the West Indies, British New Guinea, 
and elsewhere, show similar forms which are hafted by being 
bound, in various ways, to a handle of wood. In this manner 
they could be used for working wood and preparing skins, and 
also, in some cases, for hoeing the ground when there was need. 
For the latter use some of the larger ones are admirably adapted. 
A celt from Summerside, P. E. I. may have been hafted and used 
asa hatchet. It is beautifully polished, and is made of a felsite 
rock which Dr. Honeyman recognizes as the same as that oceurr- 
ing at Arisaig, N.S. It is 2.45 inches in length, while a 
similar one from the same locality is nearly 2 inches. The largest 
celt in the collection is about 10 inches long. 
The material of which one of the celts is formed, precludes it 
from being put to any rough use. It is made of soft red sand- 
stone, and is 2.45 inches in length. The edge shows but few 
marks of wear. The edge of one or two adze-like implements 
is round, so that the cutting effect may be likened to that of 
a gouge. On many of the celts, the scratches made by grinding 
show that their makers were right handed men like ourselves. 
Before going on to the next group of implements, I should like 
to mention a peculiarity in many of our celts, and also, to a cer- 
tain extent, in our gouges, which occurs so frequently as to have 
attracted my notice. The cutting edges of these implements are 
convex to a greater or less extent. The general line of the edge, 
however, is not at right angles to the axis of the implement, but 
rather cuts such an imaginary line in a more or less oblique 
direction. This makes one end of the edge higher than the other. 
When examining different specimens, I have found that, as a rule, 
this higher end is upon the same side of the celt or gouge. This
