size, they will balance the rocket in the same
manner as a stick, at the usual point of poise. To fire these, hand
them one at a time, between the tops of the wires, letting their heads
rest on the point of the wires, and the balls hang down between them:
if the wires should be too wide for the rockets, press them together
till they fit; and if too close, force them open; the wires for this
purpose must be softened, so as not to have any spring, or they will
not keep their position when pressed close or opened.

_Scrolls for Rockets._--Cases for scrolls should be made four or five
inches in length, and their interior diameters three-eighths of an
inch: one end of these cases must be pinched quite close before
beginning to fill; and when filled, close the other end; then in the
opposite sides make a small hole at each end, to the composition, as
in tourbillons, and prime them with wet meal-powder. You may put in
the head of the rocket as many of these cases as it will contain:
being fired, they turn very quick in the air, and form a scroll or
spiral line. They are generally filled with a strong charge, as that
of serpents or brilliant fire.

_Stands for Rockets._--Care must be taken, in placing the rockets,
when they are to be fired, to give them a vertical direction at their
first setting out; which may be managed thus: Have two rails of wood,
of any length, supported at each end by a perpendicular leg, so that
the rails may be horizontal, and let the distance from one to the
other be almost equal to the length of the sticks of the rockets
intended to be fired; then in the front of the top rail drive square
hooks at eight inches distance, with their points turned sidewise, so
that when the rockets are hung on them, the points will be before the
sticks, and keep them from falling or being blown off by the wind; in
the front of the rail at bottom must be staples, driven
perpendicularly under the hooks at top; through these staples put the
small ends of the rocket-sticks. Rockets are fired by applying a
lighted port-fire to their mouths.

_Table-Rockets._--Table-rockets are designed merely to show the truth
of driving, and the judgment of a fire-worker; they having no other
effect, when fired, than spinning round in the same place where they
began, till they are burnt out, and showing nothing more than a
horizontal circle of fire.

The method of making these rockets is thus:--Have a cone turned out of
hard wood two i
