At the opening of the final week of July, 1914, the whole world—with the exception of Mexico, in which the smouldering embers of the revolution still burned—was in a state of profound peace. The clattering hammers and whirling wheels of industry were everywhere to be heard; great ships furrowed the ocean waves, deep-laden with the world’s products and carrying thousands of travelers bent on business or enjoyment. Countless trains of cars, drawn by smoke-belching locomotives, traversed the long leagues of iron rails, similarly laden with passengers engaged in peaceful errands and freight intended for peaceful purposes. All seemed at rest so far as national hostile sentiments were concerned. All was in motion so far as useful industries demanded service. Europe, America, Asia, and Africa alike had settled down as if to a long holiday from war, and the advocates of universal peace were jubilant over the progress of their cause, holding peace congresses and conferences at The Hague and elsewhere, fully satisfied that the last war had been fought and that arbitration boards would settle all future disputes among nations, however serious. Such occasions occur at frequent intervals in nature, in which a deep calm, a profound peace, rests over land and sea. The winds are hushed, the waves at rest; only the needful processes of the universe are in action, while for the time the world forgets the chained demons of unrest and destruction. But too quickly the chains are loosened, the winds and waves set free; and the hostile forces of nature rush over earth and sea, spreading terror and devastation in their path. Such energies of hostility are not confined to the elements. They exist in human communities. They underlie the political conditions of the nations, and their outbreak is at times as sudden and unlooked-for as that of the winds and waves. Such was the state of political affairs in Europe at the date mentioned, apparently calm and restful, while below the surface hostile forces which had long been fomenting unseen were ready to burst forth and whelm the world.
