Lead is useful for a multitude of purposes; its great specific gravity, and the ease with which it can be melted, cut, hammered, moulded, and bent, render it especially valuable as a handy metal. Our space will not admit of our giving more than a few of the most noteworthy purposes to which it can be applied by the hunter and explorer. Projectiles of all sizes can be made from it, from the ponderous cannon shot to the small sizes used by the hunter naturalist.
Cannon shot.
Round shot for artillery, of excellent quality, can be manufactured from lead; and there is no doubt that for certain purposes it is far superior to the iron missiles in general use, the cheapness of the latter material being its great recommendation. It will sometimes happen in wild countries that although regular cannon balls are not obtainable lead is, and to make round shot from it two or three methods may be adopted. The first is to form a ball from well-mixed clay, or carve one from wood, of size to fit the bore of the piece easily, but not too loosely. The clay ball will require thorough drying in the sun or before a slow fire before use. The wooden one will merely require sprinkling over with fine ashes from the camp fire to fit it for use. Two large calabashes, wooden boxes, bowls, or cooking pots, are now to be rather more than filled with well-kneaded clay, which has been carefully freed from stones or grit, pressing it well down with a flat board until it is quite even at the surface and is perfectly compact. The clay round the edges of the two clay holders must now be trimmed off with a knife even with the sides of the holders, but projecting about an inch beyond the brim. The surface of each is now to be sprinkled with very fine ashes, and the ball pressed into the centre of the clay until it is half imbedded. It is then to be carefully removed, and pressed in like manner on the other holder. The ball is then taken out and laid aside, the two holders being allowed to dry slowly, care being taken that the clay is not cracked by the too sudden application of heat. When thoroughly dry, the vessels or holders are to be placed mouth to mouth, and so fitted, by scraping the clay, that the two indentations formed by the ball fit exactly facing each other; when this has been done, a funnel-shaped inlet must be cut for the admission of the molten lead. The two holders may now be put together, secured with a lashing of cord or strips of hide, and the metal run in at the inlet. Some time must be allowed to elapse before the mould is disturbed, or the lead will not have sufficiently settled to admit of the shot being removed without injury to the apparatus. The tail of lead formed by the inlet serves to lift the shot out by, and is then cut off flush with the surface. A number of balls may with care be made with the same pair of holders, only the greatest caution is needed in this, as with all other operations in which molten lead is used, to guard against the presence of moisture in the mould, or most serious accidents will happen.
We were busily engaged one night over the camp fire casting heavy bullets for our large smooth bore, making use of an iron ladle for the lead, and a large pair of iron moulds for the balls. These had become rather hot and were laid aside to cool; and whilst this was doing, as the lead was beginning to run rather short, we started for the tent to get more, desiring one of the Indians, who was keeping up the fire and generally aiding in the operations, to go on casting so soon as the moulds were cool. That no time might be lost, our dusky assistant plunged the hot mould in a pot of water, closed it up, and proceeded to pour in the charge of heated metal, when a violent explosion instantly took place, scattering the boiling lead broadcast over the naked legs and bodies of the unfortunate natives, sending the ladle one way, the mould another, and causing a perfect panic and dire dismay throughout the party.
Soft stones of many kinds can be conveniently made use of for casting in, taking two of equal size, scooping out the cavity in each stone of the form intended to be given to the casting, and then cutting an inlet. Common Bath scouring bricks answer this purpose admirably. We constantly use them for casting fishing leads, plummets, bodies for artificial baits, &c. &c. Two bricks, or portions of brick, are made use of. The surfaces are rendered smooth by rubbing them together. The intended cavity is then marked with a sharp point on each half, and scooped neatly out with a knife, chisel, or other convenient instrument; when finished, notched, and the inlet cut, the two halves are tied together with tape and the lead poured in. Objects of six or seven pounds weight can be made by the use of two common scouring bricks. Balls of large size are often made in the East by hammering square masses of lead, or iron, on an anvil until sufficiently round for use. Great labour and no little skill are required to perform the operation, which after all leads to very unsatisfactory results, the balls being rough and untrue, corresponding with the interiors of the barrels they are intended to be fired from. We have seen heavy stones and bits of iron covered with lead fired from the most unpromising looking matchlocks, which, somehow or another, deliver their charge with greater force and accuracy than would be anticipated on a first examination. The best moulds for casting bullets of all sizes and forms are those made from gun-metal, bronze, or brass.
Buck-shot mould.
A buck-shot mould of either of these materials will be found of great value. We have one which has proved on many occasions of the greatest service; it is constructed to contain two rows of cavities for the shot, seven in each row, one above the other; so that when the groove leading to the inlets is filled with lead, and all the cavities are charged, the second row is turned upwards and treated in the same manner. The shot, when cold, are cut from their necks with a knife or strong pair of scissors, and are then fit for use. They should be about the size of common peas, and a charge of them from a large powerful gun is tremendously effective; they are extremely useful for deer jumping, antelope shooting, wild goose or bustard stalking. At very short distances, and in close encounter with a large animal, they may be used with destructive effect, but must be only considered in the light of a makeshift when the true large game of the forest has to be dealt with. Against attacking hordes of savages, in a bush fight, or canoe encounter, they are invaluable. The charge must be proportioned to the size of the guns; those of heavy metal and large bore generally deliver them best.
Slugs, to make.
Slugs are to be made by filling a box or large pot with fine clean sand, forcing it down tight, and then with a smooth round stick, about the size of a small pencil, making a number of holes from the surface to the bottom of the vessel or receiver in which the sand has been placed. When as many are made as the space will admit of, pour the molten lead steadily into them until they are filled; when cold, the sand can be thrown out, and the leaden rods or pencils separated from it. These, when laid on a board in rows, can be cut up into short junks by placing a strong knife on them, and striking it on the back with any convenient instrument. Thick sheets of lead are cut up into dice in much the same manner. These are usually shaken about in a tin box or an iron pot, in order to round off the corners.
