He got no further. A pall of darkness suddenly dropped upon the room. An inky curtain seemed to have fallen from the sky. At the same time the windows were shaken by tremendous blasts of wind, and, as the electric lights were hastily turned on, huge snowflakes, intermingled with rattling hailstones, were seen careering outside. In a few seconds several large panes of glass were broken, and the chilling wind, sweeping round the apartment, made the teeth of the thinly clad statesmen chatter, while the noise of the storm became deafening. The sky lightened, but at the same moment dreadful thunderpeals shook the building. Two or three trees in the White House grounds were struck by the bolts, and their broken branches were driven through the air and carried high above the ground by the whirling winds, and one of them was thrown against the building with such force that for a moment it seemed as if the wall had been shattered. After the first stunning effect of this outbreak of the elements had passed, everybody rushed to the windows to look out--everybody except Cosmo Versál, who remained standing in the center of the room. "I told you!" he said; but nobody listened to him. What they saw outside absorbed every faculty. The noise was so stunning that they could not have heard him. We have said that the air lightened after the passage of the first pall of darkness, but it was not the reappearance of the sun that caused the brightening. It was an awful light, which seemed to be born out of the air itself. It had a menacing, coppery hue, continually changing in character. The whole upper atmosphere was choked with dense clouds, which swirled and tumbled, and twisted themselves into great vortical rolls, spinning like gigantic millshafts. Once, one of these vortexes shot downward, with projectile speed, rapidly assuming the terrible form of the trombe of a tornado, and where it struck the ground it tore everything to pieces--trees, houses, the very earth itself were ground to powder and then whirled aloft by the resistless suction. Occasionally the darkness returned for a few minutes, as if a cover had been clapped upon the sky, and then, again, the murk would roll off, and the reddish gleam would reappear. These swift alternations of impenetrable gloom and unearthly light shook the hearts of the dumfounded statesmen even more than the roar and rush of the storm. A cry of horror broke from the onlookers when a man and a woman suddenly appeared trying to cross the White House grounds to reach a place of comparative safety, and were caught up by the wind, clinging desperately to each other, and hurled against a wall, at whose base they fell in a heap.
