116 STONE IMPLEMENTS OF THE ABORIGINES OF 
is exhibited as showing that many water-worn flat pieces of stone 2 
require very little work in the w ay of grinding and polishing to 
convert them into aboriginal hatchets. 
As regards the remaining implements from New South Wales, 
there is tite chisel, of eevee well ground and polished ; 
there is the knife, from Lake acquarie, broad, and three-sided, 
like a fragment of a hay-knife. Its greasy appearance may be a 
true index of the use to which it was applied. There is the 
sharpening-stone, red in colour, apparently of sandstone forma- 
tion, and well adapted for its purpose. The effect of rubbing some 
hard substance systematically upon it is quite evident from the 
grooved surface on each side of the thin fragment itself. The pound- 
ing-stone is also of red colour, and very heavy, being well fitted to 
pound up seeds or crack bones of large animals for the marrow. 
Going now across the border, — is — one hatchet from 
Victoria, about which some remarks may be e. It has all the 
appearance of having been a iaiieenone ie of volcanic roc 
called ‘“ blue-stone” ‘commonly in Victoria. It has been skilfully 
chipped, so that the whole of the smooth surface on one side has 
own tale. It has also been chipped at oe mee so as to form a 
bedding for a handle. Scratches and dints on the remaining 
ry 
stroke would have sithiee broken the 
implement in pieces, or au ust off a flake from the wrong 
side. It was found halfway between Ballarat and Geelong, between 
the Leigh River and the Moorabool. It has a specific gravity of 
about two and a half, the same as that of the volcanic rock in the 
neighbourhood, while a close-grained hatchet found in the same 
or eT The chipping, however, must have been very skil- 
fully effected. A fal 
has a c t three. 
The sharp dakes exhibited from Victoria were picked up by the 
writer at one of the quarries of the aborigines he quarry was 
not a depression formed by the removal of tons of stone. In fact it 
was a little knoll where very hard flinty and —_ rock cropped 
sia and acon in blocks. The space for a quarter of an acre was 
ess covered with thousands of chips saioes off the rock,

to 24 inches. The ength from the point to the centre of the cut- 
ea cies eres and an eighth. It weighs 6 ounces. The
