The bolas is carried knotted up in a pouch slung round the neck, a native frequently carrying several sets. When a flock of ducks is seen approaching, the handle is grasped in the right hand, the balls in the left, and the strings are straightened out with a quick pull. Letting go with the left hand the balls are whirled round the head and let fly at the passing flock. The balls spread apart in flying through the air, so as to cover considerable space, like a charge of shot, and if they are stopped by striking a duck, the strings immediately wrap around him and hamper his flight so that he comes to the ground. The natives said that the balls flew with sufficient force to stun a duck or break his wing, but we never happened to see any taken except in the way just described. A duck is occasionally left with sufficient freedom of motion to escape with the bolas hanging to him. The weapon is effective up to 30 or 40 yards, but the natives often throw it to a longer distance, frequently missing their aim. It is universally employed, especially by those who have no guns, and a good many ducks are captured with it. In the spring, when the ducks are flying, the women and children hardly ever stir out of the house without one or more of these. [Illustration: FIG. 247.--Bird bolas, looped up for carrying. 1/4] [Illustration: FIG. 248.--Bird bolas, ready for use. 1/6] We brought home one specimen of this implement (kelauĭtau´tĭn), No. 75969 [1793], Fig. 248, which is new and has the balls rather carelessly made. The balls, which are six in number, are of walrus ivory, 1.6 to 1.8 inches long and 1 inch in diameter (except one which is flattened, 2 inches long and 1.3 wide; they are usually all of the same shape). Through the larger end is drilled a small hole, the ends of which are joined by a shallow groove running over the end, into which the ends of the strings are fastened by three half-hitches each. There is one string of sinew braid to each set of two balls, doubled in the middle so that all six parts are equal and about 28 inches long. They are fastened to the feather handle as follows: Nine wing feathers of the eider duck are laid side by side, butt to point, and doubled in the middle so that the quills and vanes stand up on all sides. The middle of each string is laid across the bight of the feathers, so that the six parts come out on all sides between the feathers. The latter are then lashed tightly together with a bit of sinew braid, by passing the end over the bend of the feathers and tying with the rest of the string round the feathers.
