The single-barrel gun has passed out of modern sport; but I remember mine with regret, and think I shall some day buy another. I still find that the best double-barrel seems top-heavy in comparison; in poising it the barrels have a tendency to droop. Guns, of course, are built to balance and lie level in the hand, so as to almost aim themselves as they come to the shoulder; and those who have always shot with a double-barrel are probably quite satisfied with the gun on that score. To me there seems too much weight in the left hand and towards the end of the gun. Quickness of firing keeps the double-barrel to the front; but suppose a repeater were to be invented, some day, capable of discharging two cartridges in immediate succession? And if two cartridges, why not three? An easy thought, but a very difficult one to realise. Something in the _power_ of the double-barrel--the overwhelming odds it affords the sportsman over bird and animal--pleases. A man feels master of the copse with a double-barrel; and such a sense of power, though only over feeble creatures, is fascinating. Besides, there is the delight of effect; for a clever right and left is sure of applause and makes the gunner feel "good" in himself. Doubtless, if three barrels could be managed, three barrels would be more saleable than doubles. One gun-maker has a four-barrel gun, quite a light weight too, which would be a tremendous success if the creatures would obligingly run and fly a little slower, so that all four cartridges could be got in. But that they will not do. For the present, the double-barrel is the gun of the time.
