To-day a mine consists of a quantity of small effects such as stars, crackers, squibs, etc., blown simultaneously from a case, or in display work—from a mortar. In the latter event they are made up into bags with the lifting charge below, and are known technically as “bags.”
The “Mine of Serpents” and “Jack-in-the-Box” as sold in the shops consist of a rolled paper case which acts as the mortar, at the bottom of which is a lifting charge. This case has a light strawboard cover with a central hole, through which passes a case charged with a golden fountain composition, the lower end of which is not—as is generally the case—“clayed.” The space round the central case is filled in with squibs or crackers. When lighted the fountain case functions in the usual way, but when finished ignites the lifting charge, which lights and blows up the contained fireworks.
A very early reference to the “Jack-in-the-Box” is by John Babington (1635). In Chapter XXXVII he says: “Another which I call Jack in a Box. The order of making this is after this manner: provide a box of plate, of what largeness you please—then putting in a quantity of corn powder or powder dust (in the bottom of the box) you shall fill it with fisgigs or serpents, leaving a case in the middle for a cane to go through to the bottom, which cane must be filled with a slow receipt, in which you shall put a quantity of champhire but no oyles, in regard of the narrow passage it has to burn without any other vent.” He then describes fitting the pasteboard top and concludes: “and light your cane, which will appear like a candle, and after a pretty distance of time you shall heare a sudden noyse and see all those fisgigs flying some one way, some another. This toy has given great content to the spectators.”
Frézier calls mines “Pots à feu” or “d’aigrettes,” which, he says, were three, four, or five inches in diameter, and twelve to eighteen inches in length. When fired in batteries they were called “Pots de brins.”
The smaller kind were ignited at a vent formed by choking the case, the vent—when the case was in position—pointing downward. The larger sorts were lighted from above, and were practically the same as the Jack-in-the-Box, with the difference that there was a case similar to a shell fuse instead of the central Roman candle.
Jones’ description of “Pots d’aigrettes” and “Pots de brins” are similar, only that he fires the former with a Roman candle in the centre of the central mortar of a group with a lighter from it to each of the others, so that at the finish of the Roman candle the mortars are discharged simultaneously.
An elaboration of the “Jack” is the “Devil-among-the-Tailors,” which is the same device surrounded by Roman candles.
The next fireworks in this class—the Roman candle—is one whose genesis presents a most interesting study. From the evidence available there seems no doubt that this firework, in spite of its name, originated in this country.
The first mention of anything resembling it is found in Babington’s book. He describes what he calls “a trunck of fire which shall cast forth divers fire balls.” It is one of a class, apparently in favour at this time, intended to be carried on a staff, and known collectively as “fire lances” or “clubs” (the former name is not to be confused with the lances used in set-piece work).
The particular one under consideration, although it is very large, being four inches bore, and only emits two balls or stars, is undoubtedly the prototype of the “Roman.”
