Cartridges for either brass or iron guns are best made of some woollen material; trade serge or old blanketing answers very well for the purpose. Bags should be made a little less than the bore, and into these the charge of powder is to be poured. A piece of woollen thread, double worsted, or twine should now be used to close the end of the bag, after which it is to be passed two or three times round the bag, giving it at the same time a compact cylindrical form by rolling on a board or table under the hand. Passing the thread through the substance of the cartridge aids much in keeping its form and facilitates loading. A cartridge needle should be used to perform this operation. This needle can be easily made from a piece of stout copper or brass wire. Flatten out one end, drill or punch a hole in it to form the eye, and file the other end sharp for a point. Fourteen inches is a convenient length for a cartridge needle. It is said that a sailor’s wife enabled a British vessel to continue a long and desperate fight by pillaging the officers’ quarters of all the stockings she could find, and handing them up to be filled for cartridges. The intestines of animals, according to their size, would make as good cartridge cases as could be desired. Wads may be made of picked oakum twisted in a flat spiral to the proper size of the bore, when they are made to retain their shape by being secured here and there with fine twine passed through with the needle. In the absence of oakum, wooden wads may be made by first spokeshaving a stout pole to the size of the bore, and then sawing it up into convenient lengths.
Guns to unspike and repair.
Old guns which have been laid by will not uncommonly be found spiked, by having a common nail driven into the vent. If efficient tools are at hand this may be drilled out, if not, put a charge of powder in the gun, bore a gimlet hole in one of your wooden wads, through which pass a loosely-twisted string well impregnated with dissolved gunpowder, and afterwards dried. Cut the end of your prepared string just at the muzzle of the gun, light it, and get out of the way, when the explosion, which soon takes place, will not unfrequently expel the spike. A gun which has had its trunnions knocked off, with a view to rendering it useless, may be made nearly as effective as ever by cutting with the axe or adze a bed for it in a stout piece of log, of such a form that the cascabel of the gun and the breech end are rather more than half buried in solid wood. The log may now be trimmed off to convenient dimensions, and all made secure by a lashing of wet raw hide rope, which rests in a broad shallow notch cut in the log to receive it. The gun and its bed are thus, as the rope dries, held together by a material little less rigid than iron.
Priming cups, to make.
The bed log and gun may now be mounted by placing a very strong round bar of hard tough wood across the slide or carriage immediately below where the trunnions would have rested. This receives a deep semicircular notch, cut to exactly correspond with it on the under side of the bed log. The gun can now be elevated and depressed in the usual manner by placing wedges under the log. The common mode of priming a gun from a flask or horn, when there are no percussion or friction tubes to be obtained, is, to say the least of it, inconvenient and dangerous. It is far better to keep on hand a few priming cups. These are made as follows: From the joints of a bamboo cut a number of little cups, the bottoms being formed by the knots of the cane; in the centre of the bottom bore a hole, with a gimlet or red hot wire, large enough to admit a piece of marsh reed, hollow cane, weed stalk, or quill, about 3in. long, and small enough in diameter to pass down into the vent of the gun easily; stop the small end with a bit of melted sealing-wax; secure the large end in the cup by the same agency.
The cup becomes now a sort of funnel, through which common fine sporting powder should be poured until both tube and cup are full, when a piece of oiled paper is strained over the top of the cup like the head of a drum, and is tied fast with twine. When the gun is to be fired, the cartridge is pierced in the usual way with the priming wire. The tube of the priming cup is now to be inserted at the mouth of the vent, and pressed down until the bottom of the cup rests on the metal of the gun, when on the port fire or linstock being applied, the paper lid is instantly burned through, and the gun discharged. In windy weather, heavy tropical rains, or at night, these cups are extremely useful.
Makeshift firearms.
A cannon, of very tolerable efficiency for close quarters, and slug or bullet charges, may be made by boring a hole partly through a piece of tough strong log, with a pump auger; bore a vent with a gimlet, put on one or two hoops or rings of iron or raw hide, and the gun is ready for use. We have seen several of these, which were effectually used during the rebellion in Canada.
In 1838, at the siege of Herat, Mahomed Shah brought up a quantity of metal on the backs of camels, and had a heavy bronze gun cast, and completely finished before the town; and when the siege was raised the king had his gun sawn to pieces and taken to Teheran. Shah Abbas, of Ispahan, had a heavy piece of artillery, but said it would delay his march, and he would much rather carry metal on camels and cast artillery before the enemy’s town.
