Pointing Small-arms

—The rear-sights of small-arms are graduated with elevation marks for certain distances, generally every hundred yards; in aiming with these as with all other arms, it is first nece ary to know the distance of the object. This being known and the slider being placed opposite the mark corresponding to this distance, the bottom of the rear-sight notch, and the top of the front-sight, are brought into a line joining the object and the eye of the marksman. The term coarse-sight is used when a considerable portion of the front-sight is seen above the bottom of the rear-sight notch; and the term fine-sight , when but a small portion of it is seen. The graduation marks being determined for a fine-sight, the effect of a coarse-sight is to increase the true range of the projectile.
