Stern could never afterward recall exactly how or when the hurricane struck them. So stunning was the blow that hurled itself, shrieking, in a tumult of mad cross-currents, air maelstroms and frenzied whirls, all across the sky; so overpowering the chill tempest that burst from those inky clouds; so sudden the darkness that fell, the slinging hail volleys that lashed and pelted them, that any clear perception of their plight became impossible.

All the man knew was that direction and control had been knocked clean from his hands; that the world had suddenly vanished in a black drive of cloud and hail and wild-whipping vapor; that he no longer knew north from south, or east from west; but that--struggling now even to breathe, filled with sick fears for the safety of the girl beside him--he was fighting, wrenching, wrestling with the motor and the planes and rudders, to keep the machine from up-ending, from turning turtle in mid-air, from sticking her nose under an air-layer and swooping, hurtling over and over, down, down, like a shattered rocket, to dash herself to pieces on the waiting earth below.

The first furious onset showed the engineer he could not hope to head up into that cyclone and live. He swung with it, therefore; and now, driving across the sky like a filament of cloud-wrack, rode on the crest of the great storm, his motor screaming its defiance at the shrieking wind.

Did Beatrice shout out to him? Did she try to make him hear? He could not tell. No human voice could have been audible in such a turmoil. Stern had no time to think even of her at such a moment of deadly peril.

As a driver with a runaway stallion jerks and saws and strains upon the leather to regain control, so now the man wrestled with his storm-buffeted machine. A less expert aeronaut must have gone down to death in that mad nexus of conflicting currents; but Stern was cool and full of craft and science. Against the blows of the huge tempest he pitted his own skill, the strength of the stout mechanism, the trained instincts of the born mechanician.

And, storm-driven, the biplane hurtled westward, ever westward, through the gloom. Nor could its two passengers by any sight or sound determine what speed they traveled at, whither they went, what lay behind, or what ahead.

Concepts of time, too, vanished. Did it last one hour or three? Five hours, or even more? Who could tell? Lacking any point of contact with reality, merged and whelmed in that stupendous chill nightmare, all wrought of savage gale, rain, hail-blasts, cloud and scudding vapor, they sensed nothing but the fight for life itself, the struggle to keep aloft till the cyclone should have blown itself out, and they could seek the shelter of the earth once more.

Reality came back with a reft in the jetty sky, the faint shine of a little pale blue there, and--a while later--a glimpse of water, or what seemed to be such, very far below.

More steady now the currents grew. Stern volplaned again; and as the machine slid down toward earth, came into a calmer and more peaceful stratum.

Down, down through clouds that shifted, shredded and reassembled, he let the plane coast, now under control once more; and all at once there below him, less than three thousand feet beneath, he saw, dim and vague as though in the light of evening, a vast sheet of water that stretched away, away, till the sight lost it in a bank of low-hung vapors on the horizon.
