Care must be taken, in placing the rockets, when they are to be fired, in order to give them a vertical direction at their first setting out; which may be managed thus. Have two rails of wood, of any length, supported, at each end, by a perpendicular leg, so that the rails be horizontal, and let the distance from one to the other, be almost equal to the length of the sticks of the rockets, intended to be fired; then in the front of the top rail, drive square hooks at eight inches distance from one another, with their points turning sideways, so that when the rockets are hung on them, the points will be before the sticks, and keep them from falling, or being blown off by the wind; in the front of the rail at bottom, must be staples, drove perpendicular under the hooks at top; through these staples, put the small ends of the rocket sticks. Rockets are fired by applying a lighted port fire, to their mouths. N. B. When sky rockets are made to perfection, and fired, they will stand two or three seconds on the hook before they rise, and then mount up briskly, with a steady motion, carrying a large tail from the ground all the way up, and just as they turn, break and disperse the stars. Of Girandole Chests, for flights of Rockets. Girandole chests, are generally composed of four sides, of equal dimensions, but may be made of any diameter, according to the number of rockets, designed to be fired; its height must be in proportion to the rockets, but must always be a little higher than the rockets, with their sticks; when the sides are joined, six in the top, as far down the chest as the length of one of the rockets with its cap on. In this top, make as many square or round holes, to recieve the rocket sticks, as you intend to have rockets, but let the distance between them, be sufficient for the rockets to stand without touching one another; then from one hole to another, cut a groove, large enough for a quick-match to lay in: the top being thus fixed, put in the bottom, at about one foot and a half distance from the bottom of the chest; in this bottom must be as many holes, as in the top, and all to correspond, but these holes need not be so large, as those in the top.
