The recoil of an ordinary 12-bore gun, loaded at the muzzle, varies from forty to forty-eight pounds, seldom exceeding the latter; that of a breech-loader varies from sixty-eight to seventy-six! And this quite independently of the enormous force which is exerted on the sides of these enlarged breech guns. The shoulder left in the barrel, too, is a formidable barrier for the charge to pass by; and, in doing this, the circle of shot in immediate contact with the barrel becomes disfigured and misshaped, so as to insure its flight only to a very short distance. In the muzzle-loader an average of 180 shots strike a target of two feet six inches diameter; but breech-loaders of the same calibre will rarely put in 120 shots; showing a clear loss of 60 pellets. This is due to the enormous jamming they have undergone in passing from the greater to the lesser area of the barrel. It is said that the paper of the cartridge fills up this enlargement; but any one who knows what the force of gunpowder is, must also know that paper intervening between the charge and the sides of the barrel would be condensed at the moment of explosion to one-fourth its original thickness. CHAPTER IX. THE RIFLE. The Rifle has at length taken its place among scientifically improved weapons. Mathematicians laboured long and earnestly to develope the important principles involved in it, and which lay hidden like latent heat, only waiting for the moment when they were to be extracted, as they were at length by experiment, the result of necessity: indeed necessity has done more for the improvement of gunnery than all the mental toil and labour bestowed on the science itself. The philosopher has sought in vain for that which mechanical skill unpatronised and unheeded forced upon the world, and that, too, in spite of prejudice and contempt; and the present generation see improvements brought out which were predicted generations before--as the following quotation from Robins clearly shows:--“Whatever state shall _thoroughly comprehend the nature_ and advantages of rifle pieces, and having facilitated and completed their construction, shall introduce into their armies their general use, with a dexterity in the management of them, they will by this means acquire a superiority which will almost equal anything that has been done at any time by the particular excellence of any one kind of arms, and will perhaps fall but little short of the wonderful effects which histories relate to have been formerly produced by the first inventors of fire-arms.”
