1883.] ` Tools used tn their Manufacture. 50T 
core thus left must have been detached with a cutting tool, prob- 
ably used as an adze. After the inner side was thus formed, I am 
inclined to think a tool somewhat on the order of a chisel was 
employed, for we find many of the vessels with smooth cut inner 
sides which I suppose to be secondary cuttings. I have found 
- celts in different quarries with ground edges only, which I am 
satisfied were used in the quarry preparation of the vessels. 
The tools used in quarrying and fashioning these dishes appear 
to me to be a class of implements entirely distinct from anything. 
which we have heretofore seen or had described. Those sharply 
pointed and rounded quartz stones with sharp points and cutting 
edges found in most quarries, were possibly used as suggested 
by others, in the hands; but to my mind they are natural forms 
not generally used. Whereas the true quarry tools were mostly 
if not always hafted and grooved, roughly it is true, but dis- 
tinctly. Their general shapes I might say are often almost iden- 
tical with implements from the drift. 
One thing very noticeable is the exceedingly rough and rude 
finish of the dishes found in the quarries, whereas their outlines 
as a rule are really symmetrical, Any one would, I think, be im- 
Pressed with the want of finish in a collection of quarry speci- 
mens, but more especially is this the case when compared with 
those small pieces elsewhere alluded to, which we find in the 
fields. The former are exceedingly rough and thick, and the latter 
often smooth, always thin and delicate, and sometimes showing a 
tude ornamentation in the lines found cut on them. 
To claim that these quarry specimens were used in anything 
like their present condition, supposing they were whole dishes, is 
unreasonable, because of our inability to imagine purposes for 
which they would have been serviceable. We find in the quarries, 
almost invariably, broken vessels which must be the failures of a 
manufactory. It will be asked, of course, where are the completed 
vessels ? Whether cached or buried remains for the future to 
disclose. We know ‘enough, however, to be able to say posi- 
tively, the completed vessel does exist; but even then we know 
4S yet but little of it in any condition. The worked surface of 
rock in that quarry with which I am most familiar, varies from 
ree to six feet beneath the present surface of the surrounding 
Soil, and the quarry pits are indicated only by slight depressions 
in the ground, now hardly observable. This filling in of the pits
