ion of the obvious primary necessity for the attainment of those qualities. We find, however, that our progress towards perfection in this direction cannot proceed beyond a certain point, except at the cost of other qualities, which cannot be sacrificed with impunity. Regarding it as a settled point that any recoil of the gun is just so much taken from the initial velocity of the ball, (and if any one doubts it, let him try the experiment of throwing a stone, and stepping backwards at the moment of propulsion,) it is obvious, that, for the attainment of the longest range, such a preponderance of weight in the gun over that of the projectile is necessary as to secure the least possible recoil, and this point seems to have been fixed by our best gun-makers at the ratio of five hundred to one, which would require a gun weighing nearly sixteen pounds to carry a half-ounce ball or shot. We use the word _ball_ from habit, meaning, merely, the projectile, which will probably never again resume its spherical shape in actual service. We conceive the perfection of precision and range in rifle-practice to have been attained in the American target-ride, carrying a slug or cone of one ounce weight,--the gun itself weighing not less than thirty pounds,--and provided with a telescope-sight, and Clark's patent muzzle. At three-quarters of a mile this weapon may be said to be entirely trustworthy for an object of the size of a man, and to have force enough at that distance to disable three men. But it is obvious that such weight and such equipments as are required for it must render it utterly useless for ordinary field-service. It becomes, in fact, a species of light artillery, and as such we are firm in the conviction that it is destined to establish for itself a reputation which will render it henceforth a necessity in the composition of an army. For troops of the line the weight of the gun should not exceed ten pounds. Now, if we reduce the rifle to that weight, and preserve the ratio of 1-500 as that of the ball, we reduce its range; for the momentum being, as every school-boy knows, in proportion to weight as well as velocity, a projectile which may be perfectly sure for two or three hundred yards flies wide of the mark at six hundred, and can hardly be found at a thousand. Here begins the operation of the sliding scale, in the necessity of sacrificing some degree of precision, in order to procure a weapon fulfilling other ind
