k rise a little above the top of the rocket, and tying the
case to it, so as to rest on the rocket: these rockets have no cones.

A third method by which they are managed is this: in the top of a
rocket fix a piece of wood, in which drive a small iron spindle; then
make a hole in the middle of the small case, through which is put the
spindle; then fix on the top of it a nut, to keep the case from
falling off; when this is done, the case will turn very fast, without
the rocket: but this method does not answer so well as either of the
former.

_To make a Rocket form an Arch in rising._--Having some rockets made,
headed according to fancy, and tied on their sticks, get some sheet
tin, and cut it into round pieces about three or four inches diameter;
then on the stick of each rocket, under the mouth of the case, fix one
of these pieces of tin 16 inches from the rocket's neck, and support
it by a wooden bracket, as strong as possible: the use of this is,
that when the rocket is ascending, the fire may play with greater
force on the tin, which will divide the tail in such a manner that it
will form an arch as it mounts, and will have a very good effect when
well managed; if there is a short piece of port fire, of a strong
charge, tied to the end of the stick, it will make a great addition;
but this must be lighted before the rocket is fired.

_To make several Rockets rise together._--Take six, or any number of
sky-rockets, of any size; then cut some strong packthread into pieces
of three or four yards long, and tie each end of these pieces to a
rocket in this manner:

Having tied one end of the packthread round the body of one rocket,
and the other end to another, take a second piece of packthread, and
make one end of it fast to one of the rockets already tied, and the
other end to a third rocket, so that all the rockets, except the two
on the outside, will be fastened to the two pieces of packthread: the
length of thread from one rocket to the other may be what the maker
pleases; but the rockets must be all of a size, and their heads filled
with the same weight of stars, rains, &c.

Having thus done, fix in the mouth of each rocket a leader of the same
length; and when about to fire them, hang them almost close; then tie
the ends of the leaders together, and prime them; this prime being
fired, all the rockets will mount at the same time, and divide as far
as the strings will allow; and this division they keep, provided
