Of course, the character of armor-plate has been vastly improved since that time. Instead of being merely soft iron, as was that of the _Monitor_, armor-plate is now made of the hardest and toughest tempered steel that science can produce. So, also, is the projectile. The projectile has far more than held its own. It is necessary, therefore, that the most heavily armored ships, as well as those unarmored, must fight today at long range, depending mainly upon skilled marksmanship and power and range of guns, rather than upon armored protection. A battle at close range between two huge modern dreadnoughts would be as deadly to both combatants as a duel between two men standing close together, face to face, holding pistols at each other's breast. When a chemical engineer makes an invention, and needs money for its exploitation, he first interests capitalists by letting them see the invention practised on a laboratory scale, embodying essentially the same conditions as would be involved in the larger commercial application. Similarly, we may get a very just and dependable idea of the relative efficiency of guns and armor-plate on a naval-battle scale, by taking into consideration what would be the result of a lesser conflict, embodying essentially the same conditions. Suppose two men were to fight a duel, one wearing armor capable of protecting him as efficiently against rifle balls as the heaviest armor carried by any warship today is capable of protecting it against modern cannon-fire; the other wearing no armor, and being thereby enabled to run much faster than his armor-clad opponent. Obviously, if the unarmored man had a gun of longer range than that carried by the protected man, he would be able to keep out of range of his enemy's gun, while still keeping him well within range. Thus he would be able to continue firing at him until he killed him, without in return being hit at all. At the battle of Santiago, the American fleet made only about two per cent. of hits with its 12-inch guns. Since that time very great improvements have been made in fire-control, and the accuracy of gun-fire. Today, a battle-cruiser, going at the rate of thirty knots, will hit an object on the sky-line a tenth the size of a battleship with the accuracy that Buffalo Bill from horse-back would hit a man's hat at a distance of twenty paces. In the naval battle between von Spee and Cradock, off the coast of Chili, they opened fire on each other with deadly effect at 12,000 yards. In the running fight off the Falkland Islands, most of the execution was done at a range of 15,000 yards.
