a pattern with the barb divided into three points seems to be the prevailing form. I will now proceed to the description of the different forms of harpoon with which these toggle heads are used. [Footnote N333: 2d Voyage, Pl. opposite p. 550, Fig. 13.] [Footnote N334: Museum collections and Nordenskiöld, Vega, vol. 2, p. 105, Fig. 1. This figure shows the blade _in the plane_ of the barb, but none of the specimens from Plover Bay are of this form.] Throwing-harpoons are always thrown from the hand without a throwing-board or other assistance, and are of two sizes, one for the walrus and bearded seal, and one for the small seals. Both have a long shaft of wood to the tip of which is attached a heavy bone or ivory foreshaft, usually of greater diameter than the shaft and somewhat club-shaped. This serves the special purpose of giving weight to the head of the harpoon, so it can be darted with a sure aim. The native name of this part of the spear, ukumailuta (Greenlandic, okimailutaĸ, _weight_), indicates its design. This contrivance of weighting the head of the harpoon with a heavy foreshaft is peculiar to the western Eskimo. On all the eastern harpoons (see figures referred to above and the Museum collections) the foreshaft is a simple cap of bone no larger than the shaft the tip of which it protects. Between the foreshaft and the toggle-head is interposed the _loose shaft_ (i´gimû), a slender rod of bone whose tip fits into the shaft socket of the head, while its butt fits loosely in a socket in the tip of the foreshaft. It is secured to the shaft by a thong just long enough to allow it to be unshipped from the foreshaft. This not only prevents the loose shaft from breaking under a lateral strain, but by its play facilitates unshipping the head. On these harpoons intended for throwing, this loose shaft is always short. This brings the weight of the foreshaft close to the head, while it leaves space enough for the head to penetrate beyond the barb.
