Let fig. 55, be a smooth circular board, six feet diameter; out of the middle of it cut a circular piece twelve or fourteen inches diameter, and over the vacancy put white Persian silk, on which paint a moon’s face, then let I, I, I, &c. be stars each four or five inches diameter, cut out with five points, and covered with oiled silk: on the front of the large circular board, draw a seven-pointed star, as large as the circle will allow; then on the lines which form this star, bore holes, wherein fix pointed stars. When this piece is to be fired, it must be fixed upon the front of a post, on a spindle, with a wheel of brilliant fire behind the face of the moon; so that while the wheel burns, the moon and stars will appear transparent, and when the wheel has burnt out, they will disappear, and the large star in front, which is formed of pointed stars, will begin, being lighted by a pipe of communication from the last case of the vertical wheel, behind the moon; this pipe of communication must be managed in the same manner as those in regulated pieces. Of the Double Cone Wheel illuminated. This piece is represented by fig 56. Let A, be a strong decagon wheel, two feet six inches diameter; then on each side of it fix a cone B and C; these cones are to consist of a number of hoops, supported by three or four pieces of wood, in the manner of the spiral wheels; let the height of each cone be three feet six inches, and on all the hoops tie port fires horizontally, with their mouths outwards, and cloath the wheel with eight ounce cases, all to play horizontally, two at a time: the cones may be fired with the first or second cases. The spindle for this piece must go through both the cones, and rise three feet above the point of the cone at top, so that its length will be ten feet four inches from the top of the post H, in which it is fixed, allowing four inches for the thickness of the block of the wheel; the whole weight of the wheel and cones must bear on a shoulder in the spindle, on which the block of the wheel must turn; near the top of the spindle, must be a hole in the front, into which screw a small spindle, after the cones are on; then on this small spindle fix a sun D, composed of sixteen nine inch four ounce cases of brilliant fire, which cases must not be placed on a fell, but only stuck into a block of six inches diameter; then in the front of this sun must be a circular vertical wheel, sixteen inches diameter; on the front of this wheel form with iron wire a spiral line, and cloath it with illuminations, after the usual method; as this wheel is not to be fired till the cones are burnt out, the method of firing it is as follows; let the hole in the block, at the top of the uppermost cone, be a little larger than the spindle which passes through it; then from the first case of the vertical wheel before the sun, carry a leader down the side of the spindle to the top of the block of the horizontal wheel, on which must
