Diameter of the Calliber, by Rowling Paper or thin Paste-board on a
woodden Rowler; choak the ends only, leaving at one end a passage to
thrust in a Goose-Quill filled with Dust-Powder and Charcole well mixed,
at a Port-fire, Glue them over, or use small Cord glued or pitched to
strengthen the Case that it burst not unseasonably by the force of the
Composition, with which you must fill them when you have choaked; only
at the Port-fire end, the Composition being about 2 Inches, the same as
the former, the rest corned Powder, having primed and fixed them on a
Plank in a Row about a foot distance, lay a train of Stouple, and they
will fire gradually, flying about on the Earth or the Water, according
as you place them, giving reports like a Volley of Muskets.

This Stouple is useful for Trains; and Port-fire is no more than
Cotton-wool well dressed in water and Gun-powder dryed in the Sun, or in
a clean Swept warm Oven, that it may come somewhat near Tinder, but more
swift and fiercer in its fire when it has Taken.


_Fire-Boxes, To make them._

Take a great Cartoush or Case made, as for the Balloon, croud it full of
small Rockets or Serpents, with the choaked part downward, prime them
with Stouple or Wild-fire; fix it firm on a Pole, make a priming Hole in
the side towards the lower end, and run in a Quill of fine beaten
Powder, and they will fly out (the upper end being left open) one by one
as swift as may, or if you scatter loose Powder they will fly out
several together with a prodigeous Noise, and breaking, imitating a deal
of Thunder.
