28 MK. W. 0. CLARKE ON NEOLITHIC MAN IN THETFORD DISTRICT. 
leaf-sliaped, lozenge-shaped, and triangular; the barbed, and those 
with only a basal stem being included in the latter. As bronze 
arrowheads have never been found in Britain, arrow points of Hint 
must have continued in use during the Bronze age, and it is there- 
fore impossible, in ordinary cases, to refer them correctly to either 
age. However, in Thetford district, on account of the extreme 
rarity of remains of the Bronze age, showing it to have been very 
sparsely populated during that period, we are justified in concluding 
that these arrowheads belong to the Neolithic age. Leaf-shaped 
arrowheads are very rare in the neighbourhood, though Mr. F. Bussell 
has one found on Thetford Abbey Heath that is perfect in shape 
and exquisitely balanced. It is of the type known as the ash-leaf 
arrowhead and a peculiarity is, that in addition to the secondary 
chipping, the more obtrusive angles have been rubbed off, thus 
making it a most symmetrically finished implement. Lozenge- 
shaped arrowheads, too, are uncommon, and those that can be 
referred to this type are generally very rough. Of the old variety 
of indented or hollow-based arrowheads, now classed with triangular, 
Elveden has proved a fertile hunting-ground. One I have from 
Santon Warren had been previously chipped, and has a more acutely 
hollowed base than is usual, the length from point to extremity of 
hollow base inch, and from point to extremity of barb being 
ljf inches. Another I have from the same locality is formed by 
utilising a very thin and sloping flake, the chipping starting from 
the central ridge and running to the edge on one side, whilst on the 
other the smooth slope of the flake is used, the chipping on the edge 
being extremely minute. The length of this specimen is 11 inches, 
and the width at the base f inch. None of the arrowheads in my 
collection are of black flint, though various shades of blue and 
yellow are represented. The average length of barbed specimens 
from this locality is 1|- inches, the width at the base and the length 
being equal in the most symmetrical specimens. 
The history of the smallest arrowhead I possess is rather inter- 
esting, if my conjectures regarding it are correct. We know that 
in Denmark, during the Later Stone Age, religious feeling was very 
highly developed, and the best of everything was dedicated to the 
gods, and put aside for their use. Thus it is, that in the peat-bogs 
of Denmark, finds of exquisitely polished flint axes are occasionally 
made, hidden under huge slabs of stone, and mingled with superb
