Ballóóns filled with crackers, reports, and marrons, make no great show of themselves, nor are they very pleasing to the eye, for they represent nothing more than a number of pale white flashes, followed by a variety of reports; which altogether make but a very indifferent appearance when fired with illuminated ballóóns, which are so beautiful and brilliant, as to cast forth such lustre that will dazzle the eyes of the spectators for some time; on this consideration, I do not think it worth while loading shells of a large nature, with things that afford so little pleasure: but they have a pretty good effect in royal shells, when thrown among a number of air works, such as pots des brins or flights of rockets, in order to alarm the people with a thundering in the air. For they will not know from whence the reports came, if fired exactly at the same time with the other works, and the fuze made to carry a small fire. But if any one thinks proper to make large ballóóns of this sort, it is only observing a proportion of the blowing and firing powder, and the length of the fuze, for shells of the same dimensions as those you intend to make. These kind of ballóóns are lighter than any other sort, by reason of the crackers being light of themselves, and not lying close in the shells. It must be observed, when you fire light ballóóns, not to put so much powder in the mortar as for heavy ones. Compound Eight-inch Ballóóns. oz. dr.
