It consists of a small wooden cylinder, about three quarters of an inch in diameter, and 3 in. long; at one end of the cylinder is a cavity which holds the combustible, which is confined only by pasteboard or membrane, so that, when ignited, it will blow straight into the heart of the principal charge; the two wires of the electric circuit, entering at the other end of the cylinder, terminate upon the little wooden disc which forms the bottom of this cavity, so that the end of one wire is about a quarter of an inch from the other; the electric circuit is completed by drawing a dash with a blacklead-pencil across the tiny space of the wooden surface connecting the two ends of wire; and the fusee is then charged.
