Bob looked at Lang.

Lang considered. As he hesitated Bob guessed his thoughts. Some one from the small field, some member of the plant staff, probably Mr. Parsons, finding the ’plane belonging to Griff gone, and hearing from the watchman who had taken it, had taken off in the cabin monoplane to stop what he probably considered a prank of Lang and Bob—some night-flying lark.

What would Lang say? Set down? Or—go on?

They could outfly that cabin ship in the speedy, easily maneuvered sport craft—or, they could, with Lang at the controls. But Lang was badly upset in his stomach. What would he decide? Bob mechanically looked around for the best spot to set down.

When he looked up again his heart leaped with exultation.

Lang’s arm pointed straight ahead!

“Go on!” he gestured.

Bob opened the throttle joyously. Here was adventure, pursuit, thrill enough to suit anyone!
