Speech again became impossible. As before, sheets of water—which bore no relation to rain, but seemed rather as though the earth were at the foot of a waterfall from which a river was leaping from on high—were hurled over the land. The shrieking of the wind had a wild and maniacal sound, the sound which Jamaicans have christened "the hell-cackle of a hurricane." This squall lasted longer, five minutes or more, and when it passed, the wind dropped somewhat, but did not die down. It raged furiously, its shriek dropped to a sullen and menacing roar.
"Such a hurricane as this," the "Ol' Doc" continued, "has taken many days to brew. Day after day the air has remained in its ominous quietude over the surface of the ocean, becoming warmer and warmer, gathering strength for its devastating career. The water vapor has risen higher and higher. Dense cumulus clouds have formed, the upper surfaces of which have caught all the sun's heat, intensifying the unstable equilibrium of the air. The powers of the tempest have grown steadily in all evil majesty of destructiveness. Day by day, then hour by hour, then minute by minute, the awful force has been generated, as steam is generated by fierce furnace fires under a ship's boilers.
"Why, Stuart, it has been figured that the air in a hurricane a hundred miles in diameter and a mile high, weighs as much as half-a-million Atlantic liners, and this incredibly huge mass is driven at twice the speed of the fastest ship afloat. In these gusts, which come with the rain squalls, the wind will rise to a velocity of a hundred and twenty miles an hour. It strikes!"
A crack of thunder deafened all, and green and violet lightning winked and flickered continuously. The hiss of the rain, the shrieking of the wind and the snapping crackle of the thunder defied speech. The heat in the hurricane wing was terrific, but Stuart shivered with cold. It was the cold of terror, the cold of helplessness, the cold of being powerless in such an awful evidence of the occasional malignity of Nature.
Between the approach of night and the closing in of the clouds, an inky darkness prevailed, though in the intervals between the outbursts of lightning, the sky had a mottled copper and green coloration, the copper being the edges of low raincloud-masses, and the green, the flying scud above.
Squall followed squall in ever-closer succession, the uproar changing constantly from the shriek of the hundred-mile wind in the squall to the dull roar of the fifty-mile wind in between. The thunder crackled, without any after-rumble, and the trembling of the ground could be felt from the pounding of the terrific waves half a mile away. Then, in a long-drawn-out descending wail, like the howl of a calling coyote, the hurricane died down to absolute stillness.
"Whew!" exclaimed Stuart, in relief. "I'm glad that's over."
"Over!" the scientist exclaimed. "The worst is to come! We're in the eye of the hurricane. Look!"
Overhead the sky was almost clear, so clear that the stars could be seen, but the whirl of air, high overhead, made them twinkle so that they seemed to be dancing in their places. To seaward, a violet glow, throbbing and pulsating, showed where the lightning was playing.
"I'm going out to see if all's safe," said the scientist. "Do you want to come?"
