For Black.—Mealed-powder and charcoal.

These may be used in any proportion the practitioner may think proper, for a little experience will prove to him that various colours of fire may be produced by only varying the proportions or order of the ingredients, or by rendering them alternately predominant. The same observation will apply to many other cases of a similar nature.
[SECTION VIII.]
Compound Fire-Works.
Compound Fire-Works are those resulting from the combination of the single or more simple kind; principally those which we have already described. The number and variety of figures, and the modification of which they are susceptible, is almost endless, and to describe all, or the greater part of them, would far exceed the limits of our Manual. We shall therefore consider it sufficient to select such specimens of simple arrangement as will form a proper introduction to those which are more complex; in which latter case the young Pyrotechnist must be left to his own ingenuity, which will readily dictate to him a greater variety than it would be possible for us to describe.
