This piece is called a dodecaedron, because it nearly represents a twelve sided figure, and is made thus. First have a ball turned out of some hard wood, fourteen inches diameter, when done, divide its surface into fourteen equal parts, from which bore holes, one inch and a half diameter, perpendicular to the center, so that they may all meet exactly in the middle; then let there be turned in the inside of each hole a female screw, and to all the holes but one, must be made a round spoke, five feet in length, with four inches of the screw at one end, to fit the holes; then in the screw end of all the spokes, bore a hole, five inches up, which must be bored slanting, so as to come out at one side, a little above the screw; from which cut a small groove along the spoke, within six inches of the other end, where you make another hole through to the other side of the spoke; in this end fix a spindle, on which put a small wheel, of three, or four sides, each side six or seven inches in length; these sides must have grooves cut in them large enough to receive a two or four ounce case; when these wheels are cloathed, put them on the spindles, and at the end of each spindle, put a nut to keep the wheel from falling off; the wheels being thus fixed, carry a pipe from the mouth of the first case on each wheel, through the hole in the side of the spoke, and from thence along the groove and through the other hole, so as to hang out at the screw end, about an inch. The spokes being all prepared in this manner, you must have a post, on which you intend to fire the work, with an iron screw in the top of it, to fit one of the holes, in the ball; on this screw fix the ball, then in the top hole of the ball, put a little meal powder, and some loose quick match; then screw in all the spokes, and in one side of the ball bore a hole, in which put a leader, and secure it at the end, and your work will be ready to be fired. By this leader the powder and match in the center is fired, which will light the match at the ends of the spokes, all at once, whereby all the wheels will be lighted at one and the same time; there may be an addition to this piece, by fixing a small globe, on each wheel, or one on the top wheel only. A grey charge will be proper for the wheel cases. Of the Yew Tree of Brilliant Fire.
