All of the Eskimo race, as far as I have any definite information, use toggle harpoon-heads. There are specimens in the National Museum from Greenland, Cumberland Gulf, the Anderson and Mackenzie region, and from the Alaskan coast from Point Barrow to Kadiak, as well as from St. Lawrence Island, which are all of essentially the same type, but slightly modified in different localities. The harpoon head in use at Smith Sound is of the same form as the walrus harpoon heads used at Point Barrow, but appears always to have the shaft socket made by a groove closed with thongs.[N331] In Danish Greenland, however, the body has an extra pair of bilateral barbs below the blade. The Greenlanders have, as it were, substituted a metal blade for the point only of the barbed blade portion of such a bone head as No. 89379 [795].[N332] [Footnote N331: Kane, 2d Grinnell Exp., vol. 1, pp. 412 and 413 (Fig. 1), and Bessells, Naturalist, vol. 18, pt. 9, p. 869, Figs. 6-12.] [Footnote N332: Crantz, vol. 1, p. 146, and Pl. V, Figs. 1 and 2, and Rink Tales, etc., Pl. opposite p. 10.] Curiously enough, this form of the toggle head appears again in the Mackenzie and Anderson region, as shown by the extensive collections of Ross, MacFarlane, and others. In this region the metal blade itself is often cut into one or more pairs of bilateral barbs. At the Straits of Fury and Hecla, Parry found the harpoon head, with a body like the walrus harpoon heads at Point Barrow,[N333] but with the blade _in the plane_ of the body barb. Most of the pictures scattered through the work represent the blade in this position, but Fig. 19 on the same plate has the blade at right angles to the barb, so that the older form may not be universal. At Cumberland Gulf the form of the body is considerably modified, though the blade is of the usual shape and in the ordinary position. The body is flattened at right angles to the usual direction, so that the thickness is much greater than the width. It always has two body barbs. On the western coast the harpoon heads are much less modified, though there is a tendency to increase the number of body barbs, at the same time ornamenting the body more elaborately as we go south from Bering Strait. Walrus harpoon heads with a single barb, hardly distinguishable from those used at Point Barrow, are in the collection from the Diomedes and all along the northern shore of Norton Sound, and one also from the mouth of the Kuskoquim. They are probably also used from Point Barrow to Kotzebue Sound. At St. Lawrence Island and on the Asiatic shore they are the common if not the universal form.[N334] The seal harpoon head (naulɐ) at Point Barrow appears always to have the body barb split at the tip into two, and this is the case rarely with the tu´kɐ. This form, which appears occasionally north of Norton Sound (Port Clarence, Cape Nome), appears to be more common south of this locality, where, however,
