the bird-dart throwing-stick, and this knob fits into an indentation in the butt end of the harpoon between the bone flanges; in the lower end of the shaft, on the other hand, near the grip, there are one or even two holes into which fit bone knobs in the side of the harpoon shaft, as above described.
THE BIRD-DART THROWN.
When the harpoon or the dart is to be hurled, the throwing-stick, of whatever form it may be, is seized by the grip and held backward, together with the weapon, in a horizontal position. (See illustration, page 40); being then jerked forward with force, its lower end comes away from the dart or harpoon, while, with the upper end, still fitted to its knob or peg (see illustrations on this and the next page), the thrower hurls the weapon away to a considerable distance and with great accuracy. This is an extremely simple and effective invention.
