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 o° io' 50" E., latitude 52 0 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.

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, 1J 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
