[CHAPTER XII.]
OF THE ARRANGEMENT OF FIRE-WORKS FOR EXHIBITION.
Jones (Fire-works, 8vo. 1776) observes, among other remarks, that nothing adds more to the appearance of fire-works, than placing them properly; though the management of them chiefly depends on the judgment of the maker. When water-works are to be exhibited, divide them into several sets, and fire one set after every fifth or sixth change of land and air works. Observe this rule in firing a double set of works; always to begin with sky-rockets; then two moveable pieces; then two fixed pieces, and so on; ending with a large flight of rockets, or a marron battery. If a single collection, fire a fixed piece after every wheel or two, and occasionally some air and water works.
The rules, adopted in the arrangement of fire-works for exhibition, are the following: If they are a double set, place one wheel of a sort on each side of the building; and, next to each of them, towards the centre, place a fixed piece; then wheels and so on, leaving a sufficient distance between them, for the fire to play from one, without burning the other. Having fixed some of the works in front, place the rest behind them, in the centre of the intervals. The largest piece, which is generally a regulated or transparent piece, must be placed in the centre of the building; and behind it a sun, which must always stand above all the other works. A little before the building, or stands, place the large gerbes; and, at the back of the works, fix your marron batteries, pots des aigrettes, pots des bins, pots des saucissons, air balloons, and flights of rockets. The rocket-stands may be fixed behind, or any where else, so as not to be in the way of the works.
Single collections are fired on stands, which stands are made in the same manner as theodolite stands; only the top part must be long or short, according to circumstances. These stands may be fixed up without much trouble. The following is the order of firing works, viz:
According to the arrangement, and execution of fire-works for exhibition, as given by Morel (Traité Practique des Feux d'Artifice, p. 131,) the following order is observed:
1. A salvo of artillery.
