ARTEFACTS COLLECTED 
one is figured (Fig. 9, no. 11). It is of pale brown silicious 
stone and is of a type abundant in the New World, with 
widely expanded base, for gripping and rotating, and a 
narrow, long point. The flaking extends all over one surface, 
but is limited to the edges on the other. A second example 
of larger size is of practically identical form and technique. 
Several of these are figured by Verneau, Les Anciens Patagons . 
Scrapers are numerous and of varied types. The end- 
scrapers (‘grattoirs’) are of interest as many of them exhibit 
a typically Aurignacian flaking technique along the bevelled 
edge, probably effected by pressure (Fig. 9, nos. 12—17). They 
are usually of chert and chalcedony. Side-scrapers (‘racloirs’) 
are less numerous but very variable in shape. They exhibit 
more or less careful bevel-flaking along one lateral margin 
and little or no other retouching. One of these (Fig. 9, no. 1 8), 
obtained by Miss Hamilton, consists of a very irregular flake 
of grey chalcedony with skilful flaking along one margin to 
produce the bevelled scraping-edge, the opposite surface is 
untouched. Other examples strongly resemble Moustierian 
racloirsk Fig. 9, no. 19 shows a narrow implement, 3 in. 
long, of chalcedony, which has been flaked to a bevelled 
edge all along both margins. Its deliberately-bevelled edges 
suggest that it served as a two-edged scraper, but at one end 
what appears to be a rough hafting-tang has been formed, 
the flaking here being on both surfaces. This implement 
seems to have been made from a tabular piece of chalcedony, 
since the central area of the upper surface and most of the 
lower surface are covered with a white porous ‘cortex’. It 
was obtained by Miss Hamilton with no. 18. An interest¬ 
ing compound instrument (Fig. 9, no. 20), obtained with 
the last, has its margin trimmed all round on one surface 
(antibulb), to form a very well-flaked end-scraper at one end 
and a neatly-trimmed point at the other. The bulb surface 
is unworked.
