for the cord which ties on the rockets to lie in:
therefore, instead of notches, drive a small nail in each side of the
stick, between the necks of the cases, and let the cord, which goes
round their necks, be brought close under the nails; by this means the
rockets will be as secure as when tied on singly. The rockets being
thus fixed, carry a quick-match, without a pipe, from the mouth of one
rocket to the other; this match being lighted will give fire to all at
once.
Though the directions already given may be sufficient for these
rockets, we shall here add an improvement on a very essential part of
this device, which is, that of hanging the rockets to be fired; for
before the following method was contrived, many attempts proved
unsuccessful. Instead, therefore, of the old and common manner of
hanging them on nails or hooks, make use of the following contrivance:
Have a ring made of strong iron wire, large enough for the stick to go
in as far as the mouths of the rockets; then have another ring
supported by a small iron, at some distance from the post or stand to
which it is fixed; then have another ring fit to receive and guide the
small end of the stick. Rockets thus suspended will have nothing to
obstruct their fire; but when they are hung on nails or hooks, in such
a manner that some of their mouths or against or upon a rail, there
can be no certainty of their rising in a vertical direction.
_To fire Rockets without Sticks._--You must have a stand, of a block
of wood, a foot diameter, and make the bottom flat, so that it may
stand steady: in the centre of the top of this block draw a circle two
inches and a half diameter, and divide the circumference of it into
three equal parts; then take three pieces of thick iron wire, each
about three feet long, and drive them into the block, one at each
point made on the circle; when these wires are driven in deep enough
to hold them fast and upright, so that the distance from one to the
other is the same at top as at bottom, the stand is complete.
The stand being thus made, prepare the rockets thus: Take some common
sky-rockets of any size, and head them as you please; then get some
balls of lead, and tie to each a small wire two or two feet and a half
long, and the other end of each wire tie to the neck of a rocket.
These balls answer the purpose of sticks, when made of a proper
weight, which is about two-thirds the weight of the rocket; but when
they are of a proper
