War gratifies, or used to gratify, the combative instinct of mankind, but it gratifies also the love of plunder, destruction, cruel discipline, and arbitrary power. It is doubtful whether fighting with modern appliances will continue to gratify the savage instinct of combat; for it is not likely that in the future two opposing lines of men can ever meet, or any line or column reach an enemy's intrenchments. The machine-gun can only be compared to the scythe, which cuts off every blade of grass within its sweep. It has made cavalry charges impossible, just as the modern ironclad has made impossible the manœuvers of one of Nelson's fleets. On land, the only mode of approach of one line to another must hereafter be by concealment, crawling, or surprise. Naval actions will henceforth be conflicts between opposing machines, guided, to be sure, by men; but it will be the best machine that wins, and not necessarily the most enduring men. War will become a contest between treasuries or war-chests; for now that 10,000 men can fire away a million dollars' worth of ammunition in an hour, no poor nation can long resist a rich one, unless there be some extraordinary difference between the two in mental and moral strength. The view that war is desirable omits also the consideration that modern social and industrial life affords ample opportunities for the courageous and loyal discharge of duty, apart from the barbarities of warfare. There are many serviceable occupations in civil life which call for all the courage and fidelity of the best soldier, and for more than his independent responsibility, because not pursued in masses or under the immediate command of superiors. Such occupations are those of the locomotive engineer, the electric lineman, the railroad brakeman, the city fireman, and the policeman. The occupation of the locomotive engineer requires constantly a high degree of skill, alertness, fidelity, and resolution, and at any moment may call for heroic self-forgetfulness. The occupation of a lineman requires all the courage and endurance of a soldier, whose lurking foe is mysterious and invisible. In the two years, 1893 and 1894, there were 34,000 trainmen killed and wounded on the railroads of the United States, and 25,000 other railroad employés besides. I need not enlarge on the dangers of the fireman's occupation, or on the disciplined gallantry with which its risks are habitually incurred. The policeman in large cities needs every virtue of the best soldier, for in the discharge of many of his most important duties he is alone. Even the feminine occupation of the trained nurse illustrates every heroic quality which can possibly be exhibited in war; for she, simply in the way of duty, without the stimulus of excitement or companionship, runs risks from which many a soldier in hot blood would shrink. No one need be anxious about the lack of opportunities in civilized life for the display of heroic qualities.
