MU. W. li. CLARKE ON NEOLITHIC MAN IN THETFOllD DISTRICT. 
1 leath and Thetford Warren. The reason that heaths and warrens 
form the happy hunting-grounds of the surface implement-collector, 
is partly due to the fact that they are easy of access, and therefore 
more liable to be searched, and also that the land not being good 
enough for cultivation, the surface has not been changed so much 
since primeval man roamed the country, and when the forest-fringed 
heaths would best suit his methods of life. Babbits and Moles are 
the collector’s best friends, and the best time for search is after a 
shower of rain has exposed the flints. Taking the geological for- 
mation of Red llill, on Thetford Abbey Heath, as a typical one, we 
can see the difference between the strata yielding the Paleolithic 
and Neolithic Hint implements. The section there at the time of 
excavation was recorded by Mr. H. Prigg as follows: — 
No. Feet. 
1. Surface soil ... ... ... .. 1 
2. Yellow sand, slightly clayey, with ferruginous 
seams and layers of small Hint shingle ... 5 to 7 
3. Slightly rolled and sub-angular flints in an 
ochroous sandy matrix, with seams of silt and 
chalky detritus ... ... ... ... G to 9 
4. Similar matrix, with larger chalky patches, large 
masses of flint but slightly broken, and some 
sub-angular flints ... ... ... 6to9 
It is in No. 3 that the Paleolithic implements chiefly occur, 
at from twelve to fifteen feet below the surface ; they also 
occur sparingly in the lower bed. No. 2 yields the Neolithic 
Hint implements at a distance of a few feet below the surface, 
intermingled with fragmentary pieces of pottery, some simply 
ornamented, merely impressed with the thumb or finger, or by the 
finger-nail, and some marked diagonally or horizontally with a 
pointed stick. 
Before starting on the descriptive list of implements, it is well 
to note that the word “ celt ” as applied to an implement of stone 
is now discarded by scientific men. By a transcriber’s mistake in 
the Vulgate of Job xix. 2 A, celte was written for carte, and conse- 
quently the word crept into the language, but C. K. Watson in 
‘Notes and Queries,’ and ‘Chambers’ Cyclopaedia ’ of 1889, exposed 
the fallacious use of this term.

divided into live varieties, but three are now made to suffice, the
