On the night of the 4th of October the five words: "The hour and the man," went flying over the wires from Washington throughout the length and breadth of the North American Continent. The next morning half the industries of the United States were paralysed; all the lines of communication by telegraph and rail between the east and west were severed, the shore ends of the Atlantic cables were cut, no newspapers appeared, and every dockyard on the eastern coast was in the hands of the Terrorists. To complete the stupor produced by this swift succession of astounding events, when the sun rose an air-ship was seen floating high in the air over the ten arsenals of the United States--that is to say, over Portsmouth, Charlestown, Brooklyn, League Island, New London, Washington, Norfolk, Pensacola, Mare Island, and Port Royal, while two others held Chicago and St. Louis, the great railway centres for the west and south, at their mercy, and the _Ithuriel_, with a broad red flag flying from her stern, swept like a meteor along the eastern coast from Maine to Florida. To attempt to describe the condition of frenzied panic into which the inhabitants of the threatened cities, and even the whole of the Eastern States were thrown by the events of that ever-memorable morning, would be to essay an utterly hopeless task. From the millionaire in his palace to the outcasts who swarmed in the slums, not a man or a woman kept a cool head save those who were in the councils of the Terrorists. The blow had fallen with such stupefying suddenness that as far as America was concerned the Revolution was practically accomplished before any one very well knew what had happened. Out of the midst of an apparently peaceful and industrious population five millions of armed men had sprung in a single night. Factories and workshops had opened their doors, but none entered them; ships lay idle by the wharves, offices were deserted, and the great reels of paper hung motionless beside the paralysed machines which should have converted them into newspapers. It was not a strike, for no mere trade organisation could have accomplished such a miracle. It was the force born of the accumulation of twenty years of untiring labour striking one mighty blow which shattered the commercial fabric of a continent in a single instant. Those who had been clerks or labourers yesterday, patient, peaceful, and law-abiding, were to-day soldiers, armed and disciplined, and obeying with automatic regularity the unheard command of some unknown chief. This of itself would have been enough to throw the United States into a panic; but, worse than all, the presence of the air-ships, holding at their mercy the arsenals and the richest cities in the Eastern States, proved that tremendous and all as it was, this was only a phase of some vast and mysterious cataclysm which might as easily involve the whole civilised world as it could overwhelm the United States of America.
