All the belligerent nations have already demonstrated that neither urban life, nor the factory system, nor yet corroding luxury has caused in them any physical or moral deterioration which interferes with their fighting capacity. The soldiers of these civilized peoples are just as ready for hand-to-hand encounters with cold steel as any barbarians or savages have ever been. The primitive combative instincts remain in full force and can be brought into play by all the belligerents with facility. The progress of the war should have removed any delusions on this subject which Germany, Austria-Hungary, or any one of the Allies may have entertained. The Belgians, a well-to-do town people, and the Serbians, a poor rural population, best illustrate this continuity of the martial qualities; for the Belgians faced overwhelming odds, and the Serbians have twice driven back large Austrian forces, although they have a transport by oxen only, an elementary commissariat, no medical or surgical supplies to speak of, and scanty munitions of war. On the other hand, the principal combatants have proved that with money enough they can all use effectively the new methods of war administration and the new implements for destruction. These facts suggest that the war might be much prolonged without yielding any results more decisive than those it has already yielded; indeed, that its most probable outcome is a stalemate--unless new combatants enter the field. Fear of Russian invasion seemed at first to prompt Germany to war; but now Germany has amply demonstrated that she has no reason to look with any keen apprehension on possible Russian aggression upon her territory, and that her military organization is adequate for defense against any attack from any quarter. The military experience of the last seven months proves that the defense, by the temporary intrenchment method, has a great advantage over the attack; so that in future wars the aggressor will always be liable to find himself at a serious disadvantage, even if his victim is imperfectly prepared. These same pregnant months have also proved that armies can be assembled and put into the field in effective condition in a much shorter time than has heretofore been supposed to be possible; provided there be plenty of money to meet the cost of equipment, transportation, and supplies. Hence, the advantages of maintaining huge active armies, ready for instant attack or defense, will hereafter be less considerable than they have been supposed to be--if the declaration of war by surprise, as in August last, can hereafter be prevented. These considerations, taken in connection with the probable inefficacy against modern artillery of elaborate fortifications, suggest the possibility of a reduction throughout Europe of the peace-footing armies. It is conceivable that the Swiss militia system should satisfy the future needs of most of the European States.
