How to make Swevels.
Swevels are nothing else but Rockets, having in stead of a rod (to ballast them) a little cane bound fast unto them, where through the rope passeth. Note that you must be carefull to have your line strong, even & smooth, and it must be rubd over with sope that it may not burn. If you would have your Rockets to returne againe, then binde two Rockets together, with the breech of one towards the mouth of the other, and let the stouple that primeth the one, enter the breech of the other; both kinds are expressed by the figures, the uppermost whereof representeth the single one; A B signifieth the Rocket; D E, the cane bound unto it, through which a rope passeth. The lowermost representeth the double Rocket; A B signifieth one Rocket, and C D another; E the stouple that primeth the one, and entreth the breech of the other; the cane that the rope passeth thorough is supposed to be behinde the two Rockets.
How to make Gironells, or fire wheeles.
The making of fire wheeles consisteth onely in the placing of Rockets, with the mouth of one towards the tayle of another, round about certaine moveable wheels; wherefore I thinke it sufficient only to describe the diversity of their fashions which follow.
How to make flying Dragons.
The flying Dragon is somewhat troublesome to compose; it must be made eyther of dry and light wood, or crooked-lane plates, or of thin whalebones covered with Muscovie glasse, and painted over. In the body thereof, there must bee a voyde cane to passe the rope through; unto the bottome of this cane must bee bound one or two large Rockets, according as the bignesse and weight of the Dragon shall require; the body must bee filled with divers petrars, that may consume it, and a sparkling receipt must be so disposed upon it, that being fired, it may burne both at the mouth and at the tayle thereof; then hang the wings on in such wise, that they may shake as the Dragon runnes along the line; you may dispose divers small serpents in the wings; marke the figure.
