"Incredibly strong!" he muttered to himself, as he glanced from his barometer to the shining fog ahead. "Even though the mist will be thicker over the Falls than anywhere else, there's a good possibility they may pierce it and pick us up—and then, look out for their 'planes and swift, fighting dirigibles!"
He rotated the rising-plane, and now soared to 2,800 feet. Below and on either side of him, nothing but tenuous fog. Ahead, the swiftly-approaching fan of radiance, white, dazzling, beautiful, that seemed to gush from earth so far below and to the eastward. Already the thunders of the Falls were audible.
"Where are the others?" Gabriel wondered, his thoughts seeming to hum and roar in his head, in harmony with the shuddering diapason of the muffler-deadened exhaust. "No way of telling, now. Each man for himself—and each to do his best!"
And then his thoughts reverted to Catherine; and round his heart a sudden yearning seemed to strengthen his stern, indomitable resolve—"Victory or death!"
But now there was scant time for thought. The moment of action was already close at hand. Far below there, hidden by night and dark and mist, Gabriel knew a hundred thousand comrades, of the Fighting Sections, were lying hidden, waiting for the signal to advance.
"And it's time, now!" he said aloud, thrilled by a wondrous sense of vast responsibility—a sense that on this moment hung the fate of the world. "It's time for the signal. Now then, up and at them!"
Taking the rocket—a powerful affair, capable of casting an intense, calcium light—he touched the fuse to a bit of smouldering punk fastened in a metal cup at his right hand. Then, as it flared, he launched the rocket far into the void.
Below, came a quick spurt of radiance, in a long, vivid streak that shot away with incredible rapidity. Gabriel followed it a moment, with his gaze, then smiled.
"The Rubicon is crossed," said he. "The gates of the Temple of Janus are open wide—and now comes War!"
He rose again, skimming to a still higher altitude as the glare of the great Works drew closer and closer underneath. The wind roared in his ears, louder than the whirling propellers. The whole fabric of the aeroplane quivered as it climbed, up, up above the rushing, bellowing cataract.
