226 T ardenoisian Sites on Oxenhope Moor. 
variety of forms : (Nos. 18 and 21) are trapezoids ; (Nos. 
11 and 12) are pointed at both ends ; (No. 13) is crescentic ; 
and (No. 23) is of the hollow based type, rare but character- 
istic of the Geometric Industry of the Huddersfield District. 3 
The cherts include four cores and four blades, three of which 
are worked, and a small point of the trapezoid type. Two 
large fragments of rather poor chert show worn surfaces, 
indicating that they were picked up from river or glacial 
drift, such as could be found less than a mile from the site, 
which, however, stands on the nunatak. Numerous small 
fragments of flint were found, which were whitened and 
cracked by fire. The material here varies from clear light - 
brown flint, showing no sign of patination, through mottled 
types, to densely patinated flint, the two extremes being 
present in equal proportions. The horizon of the flints 
appears to be the upper part of the clayey sand which grades 
imperceptibly into the weathered micaceous sandstone 
underneath. 
The characters of the finds at the two sites are similar, 
and it is probably safe to assume that they belong to the same 
industry and period. Of the two Mesolithic Industries of 
the Pennines, the Geometric or Narrow Blade and the Non- 
Geometric or Broad Blade industry, the present sites, with 
fairly abundant geometric points, relatively thick narrow 
blades, and an absence of obliquely truncated points, clearly 
belong to the former. In the Huddersfield district a further 
sub-division into an early and a late period, indicated by the 
predominance of the angle -graver or the micro -graver 
respectively, has been suggested. This classification, how- 
ever, cannot be applied to the Oxenhope sites, where, in 
common with the other known sites of Airedale and Wharfedale, 
gravers are not at all common. The implements themselves 
give no conclusive evidence as to their period as compared 
with other Pennine sites. The pygmy points alone show an 
association of types which might be used for comparative 
purposes, but such a comparison would demand a much 
wider experience than the writer’s. 
The Tardenoisian culture of the North of England is 
correlated with the Boreal Period, 4 and the evidence from 
Oxenhope Moor supports this view. In connection with the 
pollen analysis of the North of England peats, 5 a section of 
the peat was taken in Nab Hill Delph and examined by 
Dr. Raistrick ; the results are shown in his diagram, fig. II. 
The tree pollen frequency was low, as might be expected at 
such an exposed summit, but the spectra show the normal 
succession of the Pennine peats. The base is of transitional 
period between the Boreal and Atlantic, and so the 
Tardenoisian layer must be assigned to the Boreal period.
