NEOLITHIC CHIPPING-SITES 79 



were picked up showing traces of extensive bruising. Cores 

 or nuclei of the small flint nodules were also plentiful. 

 Two so-called pigmy implements occurred, one of which is 

 represented at Plate V., fig. 19. 



Plate V., fig. 18, represents a "fabricator" of quartz, much 

 worn and rounded at the end, possibly used for working out 

 the barbs of arrowheads and similar purposes. 



A few perforated pebbles of flint and limestone were found, 

 possibly gathered up to be used as ornaments or net weights. 



In addition to all these flint implements, about a hundred 

 rough weathered chippings of greenstone were gathered up. 

 They are pronounced by Canon Greenwell to be undoubtedly 

 flaked by human hands. On examining the series it is evident 

 that they have been roughly chipped to pointed or cutting 

 forms. One piece, as pointed out by Mr. Sheppard, is un- 

 doubtedly a chipping from a polished greenstone axe (Plate 

 V., fig. 20). So far I have only detected these greenstone 

 chippings on this one site. Perhaps a weathered basalt was 

 employed as a substitute for flint when the supply of that 

 material ran out. A series of these chippings was illustrated 

 in the "Naturalist" for November, 1905. 



Several objects traceable to Roman and later times were 

 found on the bare ground, some fragments of Roman mortaria, 

 parts of the rim and pieces of the body of the vessel studded 

 on the inside with hard grains; in the case of the Romano- 

 British kitchen-midden at Seaton Carew this material was 

 shown to be slightly fused ironstone. Several masses of very 

 hard cinder-like substance occurred, apparently the material 

 for breaking up and studding in the mortaria. The rest of 

 the pottery, all in small fragments, are part of the rims of 

 ordinary black ware, and fragments of a very rough hand- 

 made pottery in which the clay has been mixed with quartz 

 before burning. This latter is indistinguishable from some 

 that I have found in the midden at Seaton Carew. 



All the above-mentioned pottery is characteristic of the 

 Romano-British period, left at a time long subsequent to the
