CHAPTER IV.

IN A STORM.

Dwarfed to the merest midgets, the figures about the Prescott house waved enthusiastically, as the golden-winged monoplane made a graceful swoop high above the elms and maples surrounding it. Other figures could be glimpsed too, now, running about excitedly outside the barn-like structure housing the Mortlake aeroplanes.

"Guess they think you are stealing a march on them," drawled Lieut. Bradbury.

A wild, reckless feeling, born of the thrilling sensation of aerial riding, came over Peggy. She would do it—she would. With a scarcely perceptible thrust of her wrist, she altered the angle of the rudder-like tail, and instantly the obedient Golden Butterfly began racing through space toward the Mortlake plant.

The naval officer, quick to guess her plan, laughed as happily as a mischievous boy.

"What a lark!" he exclaimed. "It's contrary to all discipline, but it's jolly good fun."

Peggy turned a small brass-capped valve—the timer. At once the aeroplane showed accelerated speed. It fairly cut through the air. Both the occupants were glad to lower their goggles to protect their eyes from the sharp, cutting sensation of the atmosphere, as they rushed against it—into its teeth, as it were.

Peggy glanced at the indicator. The black pointer on the white dial was creeping up—fifty, sixty, sixty-two—she would show this officer what the Prescott monoplane could do.
