Cut some cartridge paper, into pieces, three inches and a half broad, and one foot long; one edge of each of these pieces, fold down lengthwise about three quarters of an inch broad; then fold the double edge down a quarter of an inch, and turn the single edge back half over the double fold; then open it, and lay all along the channel which is formed, by the folding of the paper, some meal powder, then fold it over and over, till all the paper is doubled up, rubbing it down every turn; this being done, bend it backwards and forwards, two inches and a half, or thereabouts, at a time, as often as the paper will allow; then hold all these folds flat and close, and with a small pinching cord, give one turn round the middle of the cracker, and pinch it close, then bind it with pack-thread, as tight as you can then in the place where it was pinched, prime one end of it, and cap it with touch paper. When these crackers are fired they will give a report, at every turn of the paper: if you would have a great number of bounces, you must cut the paper longer, or join them after they are made; but if they are made very long before they are pinched, you must have a piece of wood, with a groove in it, deep enough to let in half the cracker, this will hold it straight, while it is pinching. Fig. 36. represents a cracker compleat. Of Single Reports. Cases for reports are generally rolled on one and two ounce formers, and are seldom made larger, but on particular occasions; they are made from two, to four inches long, and very thick of paper; having rolled a case, pinch one end quite close, and drive it down, then fill the case with corn powder, only leaving room to pinch it at top, but before you pinch it, put in a piece of paper at top of the powder: Reports are fired, by a vent, bored in the middle, or at one end, just as required.
