IN PATAGONIA AND FUEGIA

old middens on Navarin, are in general far coarser in work¬ 
manship and also larger than those from the coast of Pata¬ 
gonia, though some exhibit very good technique. Most of 
them are made from indurated mudstones, passing into 
slate, or of black chert. Many of the implements collected 
are evidently unfinished, many others are broken; others, 
again, suggest only vaguely their probable function. The 
more definite types of stone implements may be classed as 
spear-heads, knives, scrapers, and chopping-tools. 
Stone spear-heads, yerkush , are now obsolete among the 
Yaghans. Several were excavated from the middens (Fig. 
ii, nos. 3—5). A very skilfully made example is shown in 
Fig. 11, no. 3. It is tanged and barbed, well flaked all 
over, and the form is symmetrical. Another tanged and 
barbed example (Fig. 11, no. 4) is badly broken, but its 
original outline can be reconstructed. It is a very thin blade 
for its size, boldly flaked with considerable skill over both 
surfaces. Fig. 11, no. 5 shows also a remarkably thin blade, 
nowhere exceeding J in. in thickness. Its flaking indicates 
very skilful workmanship. It is of the concave-based type, 
and its close resemblance to the Patagonian specimen 
(Fig. 11, no. 1) is striking, the latter exhibiting a more re¬ 
fined and delicate technique. 
The two blades shown in Fig. 11, nos. 6, 7 may, perhaps, 
be regarded as knives rather than spear-heads. They both 
are core-implements, coarsely flaked over both surfaces, the 
margins being secondarily trimmed also on both surfaces. 
No. 6 is broad leaf-shaped and sharp-edged all round. 
It closely resembles a specimen figured by Verneau (pi. xi, 
fig. 20) and obtained at La Salina, Patagonia. No. 7 is 
taken from a large, broken blade, rather less than half of 
which was found, the shape and the flaking of which suggests 
a technique very similar to that of the Solutrean ‘laurel-leaf’ 
blades of Western Europe. One is tempted to believe that
