The walrus harpoon varies in size, being adapted to the strength and stature of the owner. Of the six in our collection, the longest, when mounted for use, is 9 feet 6 inches long, and the shortest 5 feet 8 inches. The ordinary length appears to be about 7 feet. It has a long, heavy shaft (ipua) of wood, usually between 5 and 6 feet long and tapering from a diameter of 1½ inches at the head to about 1 inch at the butt. The head is not usually fastened directly to the line, but has a leader of double thong 1 to 2 feet long, with a becket at the end into which the main line is looped or hitched. At the other end of the line, which is about 30 feet long, is another becket to which is fastened a float consisting of a whole sealskin inflated. When the head is fitted on the tip of the loose shaft the line is brought down to the middle of the shaft and hooked by means of a little becket to an ivory peg (ki´lerbwĭñ) projecting from the side of the shaft. The eastern Eskimo have, in place of the simple becket, a neat little contrivance consisting of a plate of ivory lashed to the line with a large slot in it which hooks over the catch, but nothing of the sort was observed at Point Barrow. The harpoon thus mounted is poised in the right hand with the forefinger resting against a curved ivory projection (ti´ka) and darted like a white man’s harpoon, the float and line being thrown overboard at the same time. When a walrus is struck the head slips off and toggles as already described; the line detaches itself from the catch, leaving the shaft free to float and be picked up. The float is now fastened to the walrus, and, like the shaft of the seal dart, both shows his whereabouts and acts as a drag on his movements until he is “played” enough for the hunters to come up and dispatch him. This weapon is called u´nakpûk, “the great u´na or spear.” U´na (unâk, u´nañ) appears to be a generic term in Eskimo for harpoon, but at Point Barrow is now restricted to the harpoon used for stabbing seals as they come up to their breathing holes.
