which it goes
off will be sufficient to disengage it from the head of the first
fired rocket. The sticks for these rockets must be a little longer
than for those headed with stars, rains, &c.

_Caduceous Rockets._--They are such as, in rising, form two spiral
lines, by reason of their being placed obliquely, one opposite to the
other; and their counterpoise in the centre, which causes them to rise
in a vertical direction. Rockets for this purpose must have their ends
choked close, without either head or bounce; for a weight at the top
would be a great obstruction to their mounting. No caduceous rockets
ascend so high as single, because of their serpentine motion, and
likewise the resistance of air, which is much greater than two rockets
of the same size would meet with if fired singly.

The sticks for this purpose must have all their sides equal, and the
sides should be equal to the breadth of a stick proper for a
sky-rocket of the same weight as those you intend to use, and made to
taper downwards as usual, long enough to balance them, one length of a
rocket from the cross stick, which must be placed from the large stick
six diameters of one of the rockets, and its length seven diameters;
so that each rocket, when tied on, may form, with the large stick, an
angle of 60 degrees. In tying on the rockets, place their heads on the
opposite side of the cross stick; then carry a leader from the mouth
of one into that of the other. When these rockets are to be fired,
suspend them between two hooks, or nails, then burn the leader through
the middle, and both will take fire at the same time. Rockets of 1 lb.
are a good size for this use.

_Honorary Rockets._--These are the same as sky-rockets, except that
they carry no head nor report, but are closed at top, on which is
fixed a cone; then on the case, close to the top of the stick, is tied
on a two-ounce case, about five or six inches long, filled with a
strong charge, and pinched close at both ends; then in the reverse
side, at each end, bore a hole in the same manner as in tourbillons,
to be presently described; from each hole carry a leader into the top
of the rocket. When the rocket is fired, and arrived to its proper
height, it will give fire to the case at top; which will cause both
rocket and stick to spin very fast in their return, and represent a
worm of fire descending to the ground.

There is another method of placing the small case, which is by letting
the stic
