THE SELF-RECTIFYING DART.
The dart, and its larger brother the javelin, were among the earliest weapons used in warfare, and were very skilfully thrown, not only by the Roman soldiers, but by the Goths and other savage tribes who lived in the regions north of them.
These javelins were large affairs, measuring some six or seven feet in length; the handle, a tough piece of wood, was generally four and one-half feet in length, and an inch in diameter, while the rest of the length was taken up by the barbed triangular-shaped head.
Ever since those days children of all nations and climes have made toy implements, resembling those in general appearance, but varying much in size and materials used.
The little dart described below is perhaps the tiniest and least formidable of them all; but even this should not be carelessly tossed about the room in which others are playing; when, however, thrown in the open air, and away from others who might be hurt, there is considerable amusement derived from the airy bit of flying wood, which always comes down with such unerring certainty upon its spear-like head. To make this dart, take half a sheet of note-paper, double it diagonally across, so that its top edge may fall evenly upon that of one side (see Fig. 1), and cut off the surplus piece of paper which remains uncovered at the bottom of the page. Open your square, and fold it again in the other diagonal line c, d (the first is represented on Fig. 2, as a, b). Now, opening again, fold upon the line e, f, then, after opening, upon g, h. Crease all the folds as you make them. Now, having prepared your handle, which consists of a piece of wood about 8 inches long and the size of a lead pencil, cut across one end at right angles, with slits nearly or quite an inch in depth; take your paper and open it flat once more. Fold the diagonals so that the four points, a, b, c, d, shall all meet together above x, and the lines ax, bx, cx, and dx shall meet at the central line of the figure, and the four shorter lines, ex, fx, etc., form the outside edges of the figure. Insert a tiny wedge or knife-blade at the bottom of the slits, and press the paper down in the opening, bringing the folded edges through each of the four slits; remove the wedge, and the paper will be firmly held in its place. Insert a needle or headless pin in the other end of the wood, and the dart is ready for use.
