are composed of a certain number of jets of fire distributed circularly, like the spokes of a wheel. All the fusees take fire at once through channels charged with quick matches.

The mosaic represents a surface covered with diamond shaped compartments, formed at each point of intersection, four jets of fire, which run into the adjoining ones. The intervals between the jets must be a ociated with the discharge of others, so as to keep up a succe ion of fires in the spaces.
