strong resemblance to that obtained at Newport, but the fine
flakes are scarcer and generally specimens are less abundant
than on that site. Flakes and implements that have been
used as pot boilers are not uncommon on the area.
VI. Littlebury. Howe Wood, Essex. Sheet II. S.E.
Longitude 0° 10' 50" E., latitude 52° 2' 19" N. Elevation
365 feet O.D., 225 feet above the level of the Cam. Situated
in a field on the north side of Howe Wood, north of the Strethall
to Littlebury Road. This site is on a spur of the escarpment
close to the junction of the Chalk and Boulder Clay. It is
situated on a small patch of gravel which is coloured as an
ancient river gravel on the maps of the Geological Survey (11),
but is probably an out-crop of the Mid-glacial Gravel from beneath
the Boulder Clay. The soil is a tenacious clayey rainwash.
The worked flint consists of flakes, scrapers and nodules,
mostly unpatinated, black with the greenish glaze characteristic
of clay sites; a few specimens show the "toad belly" patina.
There are earthworks of uncertain age in Howe Wood.
This site was discovered by Mr. L. V. Nash and has not yet
been thoroughly surveyed.
VII. Saffron Walden. Grimsditch Wood. Essex. Sheet
III. S.W.
Longitude 0° 15' 4" E., latitude 52° 2' 31" N. Elevation
216 to 316 feet O.D., the highest point is 175 feet above the
level of the Cam in the main valley. Fields on the slope between
Grimsditch Wood and the road to Little Walden, 11/4 mile N.N.E.
of the church.
The site lies upon the west slope of a spur of the heights
that divides the drainage of the Cam from that of the Lin. Grims-
ditch Wood occupies the end of the spur which slopes down
to Little Walden. The spring-heads of the Slade, west of Walden
church, yield the nearest running water, but there is a pond in
the wood and water can easily be retained in any hollow of
the clay hill-top.
A certain amount of gravel and alluvium occurs in the valley
bottom of the Slade. The slope is Upper Chalk succeeded by
Boulder Clay. The soil on the lower part of the slope is a rain-
wash containing much Chalk and it becomes gradually more
tenacious until upon the hill top it is entirely clay. The worked
