The thunderous voice of the car from the next camp interrupted speech as it went past them.

"Good luck, Rosie! I'll leave your rear wheels alone," shouted its driver. "By-by, Allan."

"If he's worried bad about his, I'll lend him a safety-pin from my shirtwaist," drawled Rupert, lounging up, hooking his own mask. "I ain't muck-raking, but he broke his rear axle at Indianapolis, last month, and lost two wheels."

"Corrie," Gerard pursued, "you are to bring yourself back safely. I do not want any victories at the price of your wreck. Remember that I am responsible for your being at this work, and remember Flavia."

"If I wreck my car there won't be any victory," Corrie practically returned. "Besides, I have got Rupert with me to be looked after; if I were making a speed dash by myself I might take a chance or two. You never let me out alone. It's all right. They are signalling."

Rupert sprang into his seat like a rubber ball, bracing one small legging-clad foot for support; not the least of a racing mechanician's arts being that of clinging at all times to his reeling post of duty. Gerard held out his hand for Corrie's parting clasp, then exchanged a warm grip with Rupert. Between the driver and mechanician who were to play the perilous game side by side, there passed no such friendly touch. Gerard never looked at the watching violet-blue eyes of the third man during that farewell ceremony.

"Take care of yourselves," he bade.

"It's a nice morning for a ramble," observed Rupert. "Don't worry, love, we'll be in to tea."

The Mercury Titan rolled into place in the line of flaming, panting machines. The driver of the first car threw away his cigarette and sat up. There was a pause while the group of officials poised, watches in hand, the people rose, then the starter leaned forward and the first car sprang from the line.
