The next form, No. 89331 [932], Fig. 209a, has two bilateral barbs to the blade part, thus increasing its holding power. Instead of an open transverse groove to hold the thong, it has two slots parallel to the socket groove running obliquely to the other side, where they open into a shallow depression. Figs. 209b and 210, Nos. 89544 [1419] and 89377 [766], are variants of this form, probably intended for the larger seal, as the blade part is very long in proportion. No. 89544 [1419] is interesting from its close resemblance to the spear head figured by Nordenskiöld[328] from the ancient “Onkilon” house at North Cape. No. 89377 [766] is a peculiar form, which was perhaps not general, as it has left no descendants among the modern harpoon. Instead of the bilateral blade barbs it has an irregular slot on each side, which evidently served to hold a blade of stone, and the single barb of the body is replaced by a cluster of four, which are neither in the plane of the blade nor at right angles to it, but between the two. No modern harpoon heads from Point Barrow have more than two barbs on the body. The next improvement was to bore the shaft socket instead of making it by inclosing a groove with thongs. This is shown in Fig. 211 (No. 89379 [795], from Utkiavwĭñ), which is just like No. 89544 [1419] except in this respect. The line grooves first appear at this stage of the development.
