Primaeval Man in the Valley of the Lea. 125
I have not yet seen. A few chisel-ended implements occur.
Rude choppers and somewhat large scraping tools are com-
mon. All the artificially-chipped stones of this medium age
are subabraded and lustrous. They were not made where
now found, but
have been carried
by the drift for
a short distance
from the north,
or from a higher
terrace. A point-
ed weapon and
a chopper of me-
dium Palaeolithic
age are illustrated
half real size at
figs. 10 and 11
(formerly Nos.
588 and 482 in
my collection, but
now in the pos-
session of Mr.
John Evans). A
scraper from the
Thames Valley at
Hanwell (No. 9 in
collection) is il-
lustrated half real
size in fig. 12.
The tools when
seen in the un-
disturbed gravel
of the Lea are
invariably flat,
never upright, and the butt or heavy end is often towards the
Thames and the point towards the northern position from
whence they have been washed. It is rare to find implements
in situ, although I have several times so found them.
