produced, not from the wedge, nor by a mere turning 
of the ordinary tool-axe to a new purpose, but by a 
gradual sharpening of the rounded pebble which the 
more primitive man fastened, to give weight, to the stick 
which he used much as a modern ' life preserver.' 
Accordingly we may reasonably expect to find among 
the mis-called " stone axes," a term which will hence- 
forth be dropped in these notes, perhaps several kinds 
of tools, certainly two, viz. wedges (among which may 
be classed chisels) and picks or adzes ; and among wea- 
pons we may expect to find battle axes. 
But now that we have put away axes, a difficulty still 
remains. It is probably impossible always to distinguish 
with certainty between picks (or adzes) and wedges ; for 
in some cases absolutely the only difference between 
the two may have been that the one was used with a 
handle the other without. Sometimes it is easy enough 
to say to which of the two classes a stone belongs. 
Stones the sides of which are grooved or nicked, are 
obviously picks (adzes) and not wedges ; for while, on 
the one hand, the nicks or grooves are evidently 
meant and well adapted to facilitate attachment of the 
stone to a handle, that is to make it into a pick, on 
the other hand, these same nicks or grooves, were 
the stone meant to be used as a wedge, meant that is 
to receive heavy blows applied to or near one of its ends, 
would not only be useless but would even greatly 
weaken the tool. Similarly, as regards the ornamented 
Carib tools, in which the end opposite the blade, is often 
elaborately, sometimes very elaborately, carved, it 
is obvious that there could have been no inten- 
tion of inflicting heavy blows on these heads. Of
