England is at the present time the greatest maritime nation in the world; in steam and iron she has kept the superiority she had in the days of sail and wood. France and England are the two powers that have the largest military navies; and it is so far an open question which of the two is the more powerful, that they may be regarded as practically of equal strength in material for a sea war. In the case of a collision can there be assumed such a difference of _personnel_, or of preparation, as to make it probable that a decisive inequality will result from one battle or one campaign? If not, the reserve strength will begin to tell; organized reserve first, then reserve of seafaring population, reserve of mechanical skill, reserve of wealth. It seems to have been somewhat forgotten that England's leadership in mechanical arts gives her a reserve of mechanics, who can easily familiarize themselves with the appliances of modern iron-clads; and as her commerce and industries feel the burden of the war, the surplus of seamen and mechanics will go to the armed shipping. The whole question of the value of a reserve, developed or undeveloped, amounts now to this: Have modern conditions of warfare made it probable that, of two nearly equal adversaries, one will be so prostrated in a single campaign that a decisive result will be reached in that time? Sea warfare has given no answer. The crushing successes of Prussia against Austria, and of Germany against France, appear to have been those of a stronger over a much weaker nation, whether the weakness were due to natural causes, or to official incompetency. How would a delay like that of Plevna have affected the fortune of war, had Turkey had any reserve of national power upon which to call? If time be, as is everywhere admitted, a supreme factor in war, it behooves countries whose genius is essentially not military, whose people, like all free people, object to pay for large military establishments, to see to it that they are at least strong enough to gain the time necessary to turn the spirit and capacity of their subjects into the new activities which war calls for. If the existing force by land or sea is strong enough so to hold out, even though at a disadvantage, the country may rely upon its natural resources and strength coming into play for whatever they are worth,--its numbers, its wealth, its capacities of every kind. If, on the other hand, what force it has can be overthrown and crushed quickly, the most magnificent possibilities of natural power will not save it from humiliating conditions, nor, if its foe be wise, from guarantees which will postpone revenge to a distant future. The story is constantly repeated on the smaller fields of war: "If so-and-so can hold out a little longer, this can be saved or that can be done;" as in sickness it is often said: "If the patient can only hold out so long, the strength of his constitution may pull him through."
