against an oppossitely facing shoulder on the main shaft. But 

 in all of them there is at the root of the tang a downward 

 facing shoulder, which runs round it and is only interrupted 

 by the upper part of the tang bevel which narrows here. 



The upper part of the pieces is a somewhat flattened cy- 

 linder, 4 to 4'5 cm long, with a slightly convex end surface in 

 which there is a deep oval socket м2'5 to 3 cm deep), into

which the loose harpoon shaft fitted. This cylindrical part has 

 in all three pieces, a smooth, almost polished surface. The 

 largest of the pieces is also fairly smooth on the flat surface 

 of the bevel, but its convex back has long facets which are 

 the traces left by a cutting tool; there will be seen, moreover, 

 on the same side of the implement, in the sharp edge of the 

 nail-hole, a cavity which has been cut in half in boring, pres-
