SECT. XII. How to make Fire-Wheels, or as some call them Girondles.

FIrst be provided with Spinning-Wheels or the like, made easy to run round upon its Axis, Horizontal, or Vertically; and put Flags on the top of the middle, to set out the Wheel; bind Rockets to the Wheel, and Crackers betwixt each Rocket, with the Mouth of one towards the Tail of the other; thus continued, until you have fitted the Wheel quite round; which done, cover them with Paper pasted over, and coloured handsomly to set it out, that one taking Fire, they may not Fire all, and daub Soap upon them quite round, leaving the Mouth of one of them open, to give Fire thereto; the first Rocket being burned, will set Fire to the rest one after another, keep∣ing the Wheel in a contional motion, until they be all spent; you may bind Fire-Lances to these Wheels, either upright, or near over athwart, which will make to appear diversity of Fire-Circles; you must take care to place your Wheels called Gi∣rondles at convenient distance from other Fire-Works, least they should make a confu∣sion, and spoil all the Work.
