Flung from the seat, he sprawled through treetops, caught himself, fell to a lower limb, slid off and landed among thick bushes; and through these came to earth.

The wrecked 'plane, whirling away and down, fell crashing into the river that rushed cascading by, and vanished in the firelit mist.

Stunned, yet half-conscious, Gabriel presently sat up and pressed his right hand to his head. His left arm felt numb and useless; and when he tried to raise it, he found it refused his will.

"Where am I, now, I'd like to know?" he muttered. "Not dead, anyhow—not yet!"

A continuous roar of explosions shuddered the air, mingled with the booming of the mighty Falls. Shouts and cheers and the rattle of machine-guns assailed his ear. The glare of the search-lights, through the mist and steam, was darkened momentarily by thick, greasy coils of smoke, shot through by violent flashes of light as explosions took place.

Gabriel struggled to his feet, and peered about him,

"Still alive!" said he. "And I must get back into the fight! That's all that matters, now—the fight!"

He knew not, yet, where he was; but this mattered nothing. His machine had, in fact, fallen near the river bank, in the eastern section of Prospect Park, beyond the Goat Island bridge—this region of the Park having been left outside the fortifications, in the extension of the Air Trust plant.

The trees, here, had saved his life. Had he smashed to earth a hundred yards further north, he would have been shattered against high walls and roofs.

Still giddy, but sensing no pain from his injured left arm, Gabriel made way toward the scene of conflict. He knew nothing of how the tide of battle was going; nothing of his position; nothing as to what men he would first meet, his comrades or the enemy.
