Sec. XXI. Of Lances for Petards.
Lances for petards are a kind of port-fire, used in war, but not very often. As they will be noticed hereafter, it may be sufficient to remark, that they are formed of cartridge paper, and the case is strangled in the usual manner; that a small portion of bran is put in, and then about as much good priming pistol powder in grains; that the case is then strangled, or choaked, about two-thirds of its length, the remaining one-third serving for a handle; and, in using it, that the twisted end is cut off, so that the fire may communicate to the petard.
