The comet was approaching the earth with a velocity of 41,000 meters per second, or 2460 kilometers per minute, that is, 147,600 kilometers per hour; and the earth was itself travelling through space, from west to east, at the rate of 29,000 meters per second, 1740 kilometers per minute, or 104,400 kilometers per hour, in a direction oblique to the orbit of the comet, which for any meridian appeared at midnight in the northeast. Thus, in virtue of their velocities, these two celestial bodies were nearing each other at the rate of 173,000 kilometers per hour. When observation, which was in entire accord with the computations previously made, established the fact that the nucleus of the comet was at a distance no greater than that of the moon, everyone knew that two hours later the first phenomena of the coming shock would begin. Contrary to all expectation, Friday and Saturday, the 13th and 14th of July were, like the preceding days, wonderfully beautiful; the sun shone in a cloudless sky, the air was tranquil, the temperature rather high, but cooled by a light, refreshing breeze. Nature was in a joyous mood, the country was luxuriant with beauty, the streams murmured in the valleys, the birds sang in the woods; but the dwelling places of man were heartrendingly sad. Humanity was prostrated with terror, and the impassible calm of nature stood over against the agonizing fear of the human heart in painful and harrowing contrast. [Illustration: PEOPLE LEAVING PARIS. ] Two millions of people had fled to Australia from Paris, London, Vienna, Berlin, St. Petersburg, Rome and Madrid. As the day of collision approached, the Trans-Atlantic Navigation company had been obliged to increase threefold, fourfold, and even tenfold, the number of air-ships, which settled like flocks of birds upon San Francisco, Honolulu, Noumea, and the Australian cities of Melbourne, Sidney and Pax. But this exodus of millions represented only the fortunate minority, and their absence was scarcely noticed in the towns and villages, swarming with restless and anxious life. Haunted by the fear of unknown perils, for several nights no one had been able to close their eyes, or even dared to go to bed. To do so, seemed to court the last sleep and to abandon all hope of awakening again. Every face was livid with terror, every eye was sunken; the hair was dishevelled, the countenance haggard and stamped with the impress of the most frightful anguish which had ever preyed upon the human soul.
