Figs. 212 a and b (fragment) are two polished blades of slate belonging 

 to the mixed category of knives and weapon points. Their shape corres- 

 ponds fairly well to that of the blades in the following figures. 



Fig. 213a is distinctly an arrow head of the t3^ical form. The same 

 tliough with less certainty is the case with c, its shape being simJlar to that 

 of a. If the blades in figs. 212 and 213 have really been inserted in arrow 

 heads they are highly worn and blunt at the point. 



Fig. 214 is of interest as the first specimen of a stone age tigiissaat or 

 skin creaser known from East Greenland, of exactly the same type as that 

 figured by Solberg from the northern West Greenland where this implement 

 has often been found '). "We have here again the characteristic slug-shaped 

 stone with convex upper side, flat and smooth under side, chipped, unground 

 surface and slightly wrought edges. The front half of the one edge is con- 

 cavely curved thus making a sharply bounded scraping edge. According to 

 Solberg these stones must have been inserted into hafts. They may have 

 been used partly for creasing skin (especially for boots) partly for making 

 skin patterns and similar women's work.

Hammer-stones (cf. p. 40). Besides the above-mentioned celts of 

 stone (fig. 208) some rounded natural stones have been found which 

 may have been used for hammering in nails and wedges, splitting 

 bones for extracting the marrow and similar kind of work. There 

 are distinct marks of use on them. As far as we can see they have 

 been held in the hand without a haft. 



Fig. 215 shows a very beautifull}' formed stone of such a sym- 

 metrical shape that one would almost think it had been artificially 

 formed. It was found at Depot Island between Ammassalik and 

 Nualik on digging out an old house. The stone is dark brown and 

 very hard, a greenstone diabase (determined by Dr. K. I.V. Steenstrup) 

 with one almost flat and another more curved side; it has lio traces 

 of having been inserted in a haft, only distinct marks of cutting 

 are visible. The same is the case with fig. 2166, which is somewhat
