ide
six or seven inches long; these sides must have grooves cut in them
large enough to receive a two or four-ounce case. When these wheels
are clothed, put them on the spindles, and at the end of each spindle
put a nut, to keep the wheel from falling off. The wheels being thus
fixed, carry a pipe from the mouth of the first case on each wheel,
through the hole in the side of the spoke, and from thence along the
groove, and through the other hole, so as to hang out at the screw-end
about an inch. The spokes being all prepared in this manner, you must
have a post, on which you intend to fire the work, with an iron screw
in the top of it, to fit one of the holes in the ball: on the screw
fix the ball; then in the top hole of the ball put a little
meal-powder and some loose quick-match: then screw in all the spokes;
and in one side of the ball bore a hole, in which put a leader, and
secure it at the end, and the work will be ready to be fired. By the
leader the powder and match in the centre is fired, which will light
the match at the ends of the spokes all at once, whereby all the
wheels will be lighted at once. There may be an addition to this
piece, by fixing a small globe on each wheel, or one on the top wheel
only. A grey charge will be proper for the wheel-cases.
_Stars with Points._
These stars are made of different sizes, according to the work for
which they are intended; they are made with cases from one ounce to
one pound, but in general with four-ounce cases, four or five inches
long: the case must be rolled with paste, and twice as thick as that
of a rocket of the same bore. Having rolled a case, pinch one end of
it quite close; then drive in half a diameter of clay; and when the
case is dry, fill it with composition two or three inches to the
length of the cases with which it is to burn: at top of the charge
drive some clay; as the ends of these cases are seldom pinched, they
would be liable to take fire. Having filled a case, divide the
circumference of it at the pinched end close to the clay, into five
equal parts; then bore five holes with a gimblet about the size of the
neck of a common four-ounce case, into the composition; from one hole
to the other carry a quick-match, and secure it with paper: this paper
must be put on in the manner of that on the end of wheel-cases, so
that the hollow part, which projects from the end of the case, may
serve to receive a leader from any other work, to give fire t
