The Mercury did not gather speed too rapidly, rather it lingered until the pink car bore close down upon it.

"How near?" suddenly demanded Gerard, above the noise of the motor.

The mechanician reconnoitred.

"Hundred feet," he made report.

"Wave to him."

Rupert raised his hand obediently. The Mercury sprang ahead under Gerard's touch, and with an answering roar the rose-colored machine sped in pursuit.

There was no doubt that Corrie understood the play; nor that his car was easily capable of passing the sixty-mile an hour gait now held by the Mercury. But he was not allowed to pass. Each time he essayed it, the other racer swerved in front and cut off the road.

It was as dangerous a game as could well be designed, had either driver been less skilled, but it was safe enough now. Gerard was laughing as he drove, when the first tiny missile rattled against his car.

"He's pitching spare bolts," shouted Rupert, at his companion's ear, himself grimly amused. "Peevish, ain't he?"
