Abstract

Recent investigations have proved that the aborigines
obtained the siliceous rocks used in the manufacture of
their stone implements from two sources, viz.
1) From certain localities where such kinds of rocks
occur in situ
2) From the gravel deposits of pleistocene and modern
age, in the shape of waterworn boulders.
The former localities have very aptly been termed
"native quarries," but it appears that, though these quarries
were extensively worked, the material obtained from this
source was not of the same importance as that obtained
from the gravel beds.
The total of tero-watta made from
locally occurring rock, therefore, does not exceed 14 or 15
per cent.
We, therefore, see that at the outside 15 per cent, of
the tero watta were manufactured from rock obtained in quarries, while 85 per cent, were manufactured from
rocks otherwise obtained.
Now, how were the tero-watta manufactured? The
answer to this question is more difficult than it appears,
and we will first see whether the historical accounts help
to solve the problem.
In Conclusion
The raw material required for the manufacture of
tero-watta was for the greater part obtained in the shape
of water-worn pebbles from the gravel beds, for the smaller
part from so-called quarries.
It was also concluded that the parent block was broken by means of a hammer-stone.
