Fig. 132. A port-fire holder. This is made of steel, somewhat after the manner of a pair of pliers. The ends a and b are fluted, or channelled (semi-cylindrical) to receive the port-fire: a spring, riveted at c, holds it tight; by pressing on d, the burnt case drops: the end e is pointed, to enter a long stick, bored to receive it, and strengthened with a brass ferrule.
As an instrument of this kind can be obtained only when made to order, the following contrivance will serve the purpose of most amateurs. First charge some little port-fires, 3 inches long and 1/4 inch diameter, till within about 11/4 inch full: having filled a couple of dozen, or so, invert them, and knock out the dust, as with squibs; then encircle the whole, as if going to bang them; but pour in dry sand instead; empty a little sand from each, and stop the end with plaster of paris. Scrape out a little composition from the other end, and prime it with damped meal. Take two inches of a roman candle case, or a piece of turned wood, with a hole through it, fig. 133, two inches long. Have a long stick, fig. 134; cut the end, a, so that it will fit the hole in fig. 133, and enter half way up. At the other end fix a wire, z, two and a half inches long. By slipping fig. 133 on fig. 134 it is evident one inch vacancy is left to receive the sand end of the port-fire; when this is burnt out, it can be pushed out with the wire, z.
