226 THE POINT BARROW ESKIMO. 
type figured, triangular with curved edges, varying from a rather long 
triangle like the slate blade just mentioned to a 
rather short one with very strongly curved edges 
like Fig. 215a (No. 89750 [1038]), which is peculiar 
as the only walrus harpoon head with a body of 
reindeer antler. It also has an iron blade and a 
rivet of iron, not seldom with rounded basal an- 
gles so as to be almost heart-shaped, like Fig. 215) 
(No. 56621 [283]). A less common shape of blade 
is lanceolate, with the base cut off square as in 
Fig. 216a (No. 89764 |940]). Only eight blades 
out of the series are of this shape. A still more 
peculiar shape of blade, of which we saw only 
one specimen, is shown in Fig. 216) (No. 89790 
[943]). This is made of brass. It was perhaps 
meant for an imitation of the barbed blades used 
at the Mackenzie, of which I have already spoken. 
aa aia sal ates The blade, when of metal, is generally fastened 
poon heads. in with a single rivet. One only out of the whole 
number has two rivets, and three are simply wedged into the blade slit. 
The slate blades appear never 
to have been riveted; Nordens- 
kidld, however, figures a walrus 
harpoon from Port Clarence! 
with a jade blade riveted in. 
The rivet is generally made of 
whalebone, but other materials 
are sometimes used. For in- 
stance, in the series collected 
two have rivets of iron, two of 
wood, and five of rawhide, The 
body is generally made of white 
walrus ivory, (five of those col- 
lected are of hard bone, and one 
already mentioned and figured, 
No. 89750 [1038], Fig. 215a, is 
of reindeer antler), and the 
hexagonal shape, often with 
rounded edges, and the line 
grooves continued to the tip, 
as in Fig. 217a, No. 89757 [947], 
appears to be the commonest. 
Three out of the forty-eight 
have four-sided bodies. It is 
unusual for the body barb to be bifurcated, as is common farther south.
