Towering Rockets.
2. TOWERING ROCKETS.
So called from their ascending to a greater height than any others; it is effected by fixing one Rocket on the top of another of superior dimensions:—thus, suppose the lower one to be a twelve-ounce, then the upper one should be a three-ounce Rocket; the larger one must have a small head formed round its own diameter, then place the mouth of the smaller one in it; the mouth should be rubbed with mealed powder wetted with spirits of wine; the bore in the charge should not be filled, but have inserted in it a bit of quick-match, the other end of which should enter the perforations at the top of the greater Rocket, which will form a communication between them. The large Rocket must be filled only half a diameter above the piercer; if filled higher, it will begin to descend before the upper has taken fire, and produce no additional effect.
The force by which the small Rocket goes off, will be sufficient to disengage it from the other, without the use of powder to effect it; one round of paper pasted round the juncture of the two Rockets will be sufficient to connect them together.
In regard to the rods for Towering Rockets, the same principles are to be applied as for the others.
