Catherine Wheels.
These are very pretty fireworks, and are made to turn on a pivot. There are many recipes for the composition of which they are formed; 1 part camphor, 1 sulphur, 1 niter, 2 meal powder. Another is, 3 parts iron filings, 4 sulphur, 12 niter, 16 meal powder. This composition is to be rammed into small cases, and bound round a small wheel having a hole for a pivot in the center.
