The collision occurred at a height of a thousand feet, on the Fifth Avenue side of the park. Both of the airships had their aeroplanes smashed and their decks crumpled up, and the unfortunate crews and passengers were hurled through the impenetrable darkness to the ground. Only four or five, who were lucky enough to be entangled with the lighter parts of the wreckage, escaped with their lives. But they were too much injured to get upon their feet, and there they lay, their sufferings made tenfold worse by the stifling air, and the horror of their inexplicable situation, until they were found and humanely relieved, more than ten hours after their fall. The noise of the collision had been heard in Fifth Avenue, and its meaning was understood; but amid the universal terror no one thought of trying to aid the victims. Everybody was absorbed in wondering what would become of himself. When the long attended hour of sunrise approached, the watchers were appalled by the absence of even the slightest indication of the reappearance of the orb of day. There was no lightening of the dense cloak of darkness, and the great city seemed dead. For the first time in its history it failed to awake after its regular period of repose, and to send forth its myriad voices. It could not be seen; it could not be heard; it made no sign. As far as any outward indication of its existence was concerned the mighty capital had ceased to be. It was this frightful silence of the streets, and of all the outer world, that terrified the people, cooped up in their houses, and their rooms, by the walls of darkness, more than almost any other circumstance; it gave such an overwhelming sense of the universality of the disaster, whatever that disaster might be. Except where the voices of neighbors could be heard, one could not be sure that the whole population, outside his own family, had not perished. As the hours passed, and yet no light appeared, another intimidating circumstance manifested itself. From the start everybody had noticed the excessive humidity of the dense air. Every solid object that the hands came in contact with in the darkness was wet, as if a thick fog had condensed upon it. This supersaturation of the air (a principal cause of the difficulty experienced in breathing) led to a result which would quickly have been foreseen if people could have had the use of their eyes, but which, coming on invisibly, produced a panic fear when at last its presence was strikingly forced upon the attention. The moisture collected on all exposed surfaces--on the roofs, the walls, the pavements--until its quantity became sufficient to form little rills, which sought the gutters, and there gathered force and volume. Presently the streams became large enough to create a noise of flowing water that attracted the attention of the anxious watchers at the open windows. Then cries of dismay arose. If the water had been visible it would not have been terrible.
