Yew Tree of Brilliant Fire.
17. Yew Tree of Brilliant Fire.
Provide a piece of wood about four feet long, two inches wide, and one thick; at top on the flat side, fix a hoop about fourteen inches diameter; and round its edge and front place illuminations, and in the centre a five-pointed star; then on each side at about eighteen inches from the edge of the hoop place two twelve-inch cases of brilliant fire; below which place two more cases of the same size, and at such a distance that their mouths may almost meet them at top; then close to the ends of these fix two more of the same cases, which must stand parallel to the others. The cases being thus fixed, the leaders must be applied in such a manner that the illuminations and stars at top may all take fire at the same time. [Fig. 27] represents the arrangement of the article.
Fixed Fire Globes.
18. Fixed Fire Globes.
These articles are divided into two kinds, one with projected cases, the other when the cases are concealed.
For a globe with concealed cases, provide a spherical globe of any diameter; divide the surface in fourteen equal parts, and at each division bore a hole perpendicular to the centre; in every hole except one (which must be reserved for the spindle, on which it must be fixed) insert a case filled with brilliant or any other charge; the mouths of the cases must be even with the surface of the globe; from the mouths of the several cases must be cut a groove, and in it laid a leader, for the purpose of firing them altogether. The globe must be covered over with paper, and painted in what manner the Tyro thinks proper. When dry it is to be fixed upon the spindle, and it is ready for exhibition.
For projected Cases.—The preparation is nearly the same; the difference being only to let each case project from the globe about half or two thirds of its length; their mouths are to be connected by leaders, for the same purpose as before, and exhibited in the same manner.
