IN PATAGONIA AND FUEGIA 129 
Excellent flaking technique is seen in a blade (Fig. 9, no. 
21) which might function equally as a side-scraper or a knife. 
It is one of two similar implements of chert found on the 
beach at Deseado. The blade is quite thin (at no part more 
than 6 mm. in thickness) and is beautifully flaked all over 
both surfaces, one of which is almost flat, the other slightly 
convex. The latter surface (shown in the figure) is strongly 
bevelled along its straight edge, which suggests a use for 
scraping. The opposite curved margin is more equally flaked 
on both faces to a knife-edge. One end is pointed, the other 
rounded. This seemingly compound tool is closely similar 
to one figured by Verneau (op. cit., pi. xi, fig. 6) and collected 
at La Salina, on the Santa Cruz River. 
Fig. 9, no. 22 is drawn from a very attractive, leaf¬ 
shaped blade of symmetrical outline. It is of blue-green, 
very hard stone (? pitch-stone) and is 4 in. long by if in. 
wide, nowhere exceeding ^ in. in thickness. It is elliptical 
in outline with rounded ends. Flaking extends all over both 
surfaces, one of which is particularly well, though boldly, 
flaked in a manner which recalls the surface-flaking of 
Solutrean ‘laurel leaf’ blades. 
Of bone tools from the Patagonian coast I have note of 
two long, narrow bones simply ground to a point at one end, 
but otherwise unaltered; about 6f in. and 4 in. long respec¬ 
tively. They presumably served as boring tools. 
In addition to the tools of stone and bone, there was 
collected at Santa Cruz a quantity of perforated, circular 
disk-beads of limestone or, possibly, shell. They were found 
all together and, curiously enough, had been enclosed in 
a narrow tube of copper or bronze, formed by curving over 
a long, flat plate of the metal into cylindrical form. The 
small fragment of the tube which I have has been somewhat 
crushed in and the present inner diameter is slightly smaller 
than the diameter of the larger beads (45 mm. against
