A HEARTH OF THE POLISHED STONE AGE. 89 
uninjured two were still mounted in stag’s horn sockets, similar 
to those with which the discoveries in the Swiss Lake dwellings 
have made us so well acquainted. 
‘Only two are of flint, and one of fibrolite, the others being of 
chloromelanite, serpentine basalt, and diorite. They seem to 
have been formed from pebbles brought down by the Saône, and 
it is interesting to observe that the same process of manufacture 
was in use in this part of Burgundy as in Switzerland, the split- 
ting of the pebbles into the required form having been partly ef- 
fected by sawing. That some of the spare hours of those who 
frequented the hearth were employed in preparing their hatchets 
is proved by the large number of grinding or polishing stones, of 
which, counting fragments, upwards of sixty were present. M. 
Perrault regards one of the smallest of the cutting instruments, 
a little triangular celt, as a religious emblem, but it seems more 
probable that it was used as a hand-tool, like a chisel, of one of 
which the sharpened end was also found. 
’ The arrowheads of flint, twenty-three in number, present a va- 
riety of forms, leaf-shaped, triangular, lozenge-shaped and tanged, 
the latter both with and without barbs. Their general aspect 
is such as might have been expected from the locality, most of 
the forms occurring also in Switzerland. There are, however, 
one or two shaped like small hatchets, with a broad, sharp base, 
formed by the original edge of the flake from which they were 
made, and rounded, or truncated at the other end. It is stated 
that this sharp edge was intended for insertion in the wood, but 
more probably it was the other end that was thus secured, and 
the arrows were, so to speak, chisel-pointed, like the flint-tipped 
arrows which survived in use, probably for fowling purposes, after 
metals became known to the ancient Egyptians. Similar arrow- 
heads, if such they be, have been found in considerable numbers 
in Sweden, and a few in Denmark, as well as in some other parts 
of France. It seems by no means impossible that some of the 
sharp-based instruments from the. Yorkshire Wolds may have 
served a similar purpose. 
The mealing stones consist of a large block, usually of hard 
sandstone or porphyry, and a smaller stone as muller,.and are of 
the same character as those still in use in Central Africa. They 
must have been gradually eaten together with the flour they pro- 
duced, and no doubt tended to promote that wearing away of
