During the initial analyses it was considered that these artefacts repre- sented a form transitional between the long, thick end-scrapers, which appeared more common in layers 13-10, and adzes proper, which become more common in the upper layers. In the preliminary report on BNK 1 (Schweitzer & Wilson 1978: 138) it was speculated that 'adzes and small scrapers may have taken over most of the functions previously fulfilled by medium and large scrapers'. However, these 'scraper-adzes' have their maximum frequency in layers 12 and 9, while adzes do not become common before layer 4, and the fact that this artefact type is found right up to layer 1 negates the possibility that it might represent a transitional stage between the industries of the lower layers and those of the upper. B. D. Malan has suggested (1980 pers. comm.) that these might merely be scrapers made on large flakes, of which the width was reduced in order to facilitate Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
