FIre-Pots and Balls to throw out of Mens hands may be made of Potters-Clay with Ears to hang lighted Matches to them ; if they light on a hard thing they break and the Matches fire the Powder, and the half Musket Bullets contrived on them, as in the last Chapter, disperse and do much mischief.

Their mixture is of Powder, Petre, Sulpher, Sal Armonaick of each one pound, and four Ounces of Camphire pounded and searced and mixed well together, with hot Pitch, Linseed Oyl or Oyl of Petre ; prove it first by burning a small quantity, and if it be too slow add more Powder, or if it be too quick then put more Oyl or Rosin, and then it is for your use.

You must nail two Boards together like the ridge of a House, and prepare one Board longer and broader for the bottom: Between these three Boards put a Cartridge of Powder, then make it up like a Sea-Chest and fill it with pibble Stones, Nails, Stubbs of old Iron ; then nail on the Cover and the ends to the Deck, in such a place as you may fire the Powder underneath through a hole made to put a Pistol in : These are very useful to anoy an Enemy if they board you.

Take Gun-Powder 10 l. of black Pitch 6 l. fo Tarr 20 l. Salt-Petre 8 l. Sulpher Calafornia 4 l. melt these over a soft Fire together, and being well melted put 2 l. of Cole dust of the Filings of Horses Hoofs 6 l. Assa Fætida 3 l. Sagapenum 1 l. Spatula Fætida half a l. Incorporate them well together and put into this matter so prepared old Linnen or Woolen Cloath, or Hemp or Tow as much as will drink up all this matter, and of these make them up in Balls of what bigness you please, and being thrown between Decks will be a great annoyance to the Enemy.
