e wheels turn, the pots will successively be fired, and throw
into the air a great variety of fires.

BALLOON CASES.

You must have an oval former, turned of smooth wood; then paste a
quantity of brown or cartridge-paper, and let it lie till the paste
has soaked all through; this done, rub the former with soap or grease,
to prevent the paper from sticking to it; then lay the paper on in
small slips, till you have made it one-third of the thickness of the
shell intended. Having thus done, set it to dry; and when dry, cut it
round the middle, leaving about one inch not cut, which will make the
halves join much better than if quite separated. When you have some
ready to join, place the halves even together, and let that dry; then
lay on paper all over as before, everywhere equal. When the shell is
thoroughly dry, burn a vent at top with a square iron.

Shells that are designed for stars only, may be made quite round, and
the thinner they are at the opening the better; for if they are too
strong, the stars are apt to break at the bursting of the shell.
Balloons must always be made to go easy into the mortars.

MORTARS.

These mortars must be made of pasteboard, with a small copper chamber
at bottom, in which the powder is to be placed, on which the balloon
is to be put. In the centre of the bottom of this chamber make a small
hole a little down the foot: the hole must be met by another of the
same size as the foot. Then putting a quick-match, or touch-string, of
touch-paper, into the hole, your mortar will be ready to be fired.

_To load Air Balloons with Stars, Serpents, &c., &c._--When you fill
your shells, you must first put in the serpents, rains, &c., or
whatever they are composed of, then the blowing powder; but the shells
must not be quite filled. All those things must be put in at the
fuse-hole, but marrons being too large to go in at the fuse-hole, must
be put in before the inside shall be joined. When the shells are
loaded, glue and drive in the fuses very tight. The number and
quantities of each article for the different shells are as follows:

BALLOONS ILLUMINATED.
oz.
Meal-powder 1
Corn-powder 0-1/2
Powder for the mortar 2

1 oz. driven or rolled stars, or as many as will fill the shell.

BALLOONS OR SERPENTS.
