MR. W. G. CLARKE ON NORFOLK FLINT IMPLEMENTS. 221 
boulder clay and, (6) early paleolithic. Though early, interme- 
diate and late Paleolithic implements all occur in the watershed 
of the Little Ouse, none of the early or intermediate appears to 
have been recorded from the Norfolk side of the stream, and 
in the absence of detail it seems impossible to classify the 
twenty Norfolk localities with which we are acquainted, 
although those in the Little Ouse and Thet valleys undoubtedly 
belong to the late Paleolithic period. All the pits below Thetford 
have been closed for some 25 years past, and are now quite 
overgrown. But in the river-drift at Snarehill, about a mile above 
Thetford, on low ground some 200 yards from the left bank of 
the river Thet, well-worked Paleolithic implements have been 
found at odd times during the past 15 years, while raising 
stone with which to mend the roads. Mr. A. G. Cronshey, of 
Thetford, who secured those found about 1890, has a pick 
8 in. long and 4 in. wide at the butt, which has the original 
crust ; a hatchet, almost rectangular, 7 in. by 3^ in. ; three 
small axes, and an oval implement. About 1900 a fine axe 
10 in. long, 9 in. in girth and weighing 2 lb. 10 oz., was found 
here and is now in my collection. Stone for roads on the 
Shadwell estate was again raised from this pit in the winter of 
1904-5, and some excellent implements were discovered. 
The score or so of implements then found are of varying 
types, as a rule splendidly chipped, and very symmetrical. 
In some cases they have the ochreous patina on one face only, 
while in others the gravelly stain covers the whole surface. 
Mr. F. Russell, of Thetford. has eleven good examples, perfect 
in every respect, and several others not quite so good. The 
main types are four, (1) the ordinary axe, (2) the pick. (3) 
narrow oval implement, (4) broad oval or discoidal implement. 
The biggest specimen of each type measures respectively 
5i by 2% by 1] in. thick ; 8 by 3$ by 2 in. thick ; 5 by 3 by i| 
and 3 by 2.] by 1. The picks especially are very fine, having 
big butts and long tapering points. An axe belonging to 
Mr. W. A. Dutt, of Lowestoft, is y\ by 3 in. with a girth of 
9 inches at the butt and yh in. in the middle. My own 
specimens are an axe 5^ by 2i in. at the widest part, and 1 J in. 
thick, one side ochreous, the other a lustrous black ; and
