7. SCROLLS FOR ROCKETS.
These form a pleasing appendage to the heads of Rockets, that are of considerable magnitude.
They are made in cases, about four inches in length, and their interior diameter about three-eighths of an inch; both ends must be pinched quite close, one before, and the other after they are filled; then in the reverse sides make a small vent-hole to the composition, and prime them with meal powder, wetted with spirits of wine.
The heads of Rockets may be partly or wholly filled with these cases; when fired they burst quick from their confinement and form a beautiful spiral descent.
The composition may be that of Serpents, or the brilliant fire; when either are used it should be prepared strong.
