a large knot made in the other or loose end. The arrows are
practically the same as those used on the crossbow, with the
exception of a small notch which is cut in them as shown in Fig.

To throw the arrow, insert the cord near the knot in the notch of

arrow with a quick slinging motion. The arrow may be thrown
several hundred feet after a little practice.
