Versailles broke the horizon to port and slipped astern. Paris closed up, telescoped its panorama, became a mere blur, a smoky smudge. But it was long before the distance eclipsed that admonitory finger of the Eiffel.
Vauquelin manipulating the levers, the plane tilted its nose and swam higher and yet higher. The song of the motor dropped an octave to a richer tone. The speed was sensibly increased.
Lanyard contemplated with untempered wonder the fact of his equanimity: there seemed nothing at all strange in this extraordinary experience; he was by no means excited, remained merely if deeply interested. And he could detect in his physical sensations no trace of that qualmish dread he always experienced in high places: the sense he had of security, of solidity, was and ever remained wholly unaccountable in his understanding.
Of a sudden, surprised by a touch on his arm, he turned to see through the mica windows of the wind-mask the eyes of the aviator informed with importunate doubt. Infinitely mystified and so an easy prey to sickening fear lest something were going wrong with the machine, Lanyard shook his head to indicate lack of comprehension. With an impatient gesture the aviator pointed downward. Appreciating the fact that speech was impossible, Lanyard clutched the struts and bent forward. But the pace was now so fast and their elevation so great that the landscape swimming beneath his vision was no more than a brownish plain fugitively maculated with blots of contrasting colour.
He looked up blankly, but only to be treated to the same gesture.
Piqued, he concentrated attention more closely upon the flat, streaming landscape. And suddenly he recognized something oddly familiar in an approaching bend of the Seine.
"St.-Germain-en-Laye!" he exclaimed with a start of alarm.
This was the danger point….
"And over there," he reminded himself—"to the left—that wide field with a queer white thing in the middle that looks like a winged grub—that must be De Morbihan's aerodrome and his Valkyr monoplane! Are they bringing it out? Is that what Vauquelin means? And if so—what of it? I don't see …"
Suddenly doubt and wonder chilled the adventurer.
