The chief causes of accidents from the use of fire-arms arise from carelessness, and I have always observed that those persons who are most familiar with their use are invariably the most careful. Many accidents have happened from carrying guns with the cock down upon the cap. When in this position, a blow upon the cock, and sometimes the concussion produced by the falling of the gun, will explode the cap; and, occasionally, when the cock catches a twig, or in the clothes, and lifts it from the cap, it will explode. With a gun at half-cock there is but little danger of such accidents; for, when the cock is drawn back, it either comes to the full-cock, and remains, or it returns to the half-cock, but does not go down upon the cone. Another source of very many sad and fatal accidents resulting from the most stupid and culpable carelessness is in persons standing before the muzzles of guns and attempting to pull them out of wagons, or to draw them through a fence or brush in the same position. If the cock encounters an obstacle in its passage, it will, of course, be drawn back and fall upon the cap. These accidents are of frequent occurrence, and the cause is well understood by all, yet men continue to disregard it, and their lives pay the penalty of their indiscretion. It is a wise maxim, which applies with especial force in campaigning on the prairies, "_Always look to your gun, but never let your gun look at you._" An equally important maxim might be added to this: _Never to point your gun at another, whether charged or uncharged, and never allow another to point his gun at you._ Young men, before they become accustomed to the use of arms, are very apt to be careless, and a large percentage of gun accidents may be traced to this cause. That finished sportsman and wonderful shot, my friend Captain Martin Scott, than whom a more gallant soldier never fought a battle, was the most careful man with fire-arms I ever knew, and up to the time he received his death-wound upon the bloody field of Molino del Rey he never ceased his cautionary advice to young officers upon this subject. His extended experience and intimate acquaintance with the use of arms had fully impressed him with its importance, and no man ever lived whose opinions upon this subject should carry greater weight. As incomprehensible as it may appear to persons accustomed to the use of fire-arms, recruits are very prone, before they have been drilled at target practice with ball cartridges, to place the ball below the powder in the piece. Officers conducting detachments through the Indian country should therefore give their special attention to this, and require the recruits to tear the cartridge and pour all the powder into the piece before the ball is inserted.
