General Herwigs seemed to realize that further protest was useless. He drew himself up stiffly, as did the other envoys, and saluted the chancellor. Then, without another word, he re-entered the airplane.

The others took their seats, and Hal climbed again into the pilot's seat.

"All ready?" he asked.

Chester glanced around to make sure that all the passengers were ready for the trip.

"Let her go, Hal," he said a moment later.

The airplane sped across the ground. Directly it began to ascend. Soon Hal turned it a trifle so that its nose pointed toward the distant village of Hirson, where Marshal Foch and staff were awaiting the return of the two lads and the German envoys.

"And I hope," Hal muttered to himself, "that there will be no other delays."

But in this he was doomed to disappointment, and it was due to the lad's own carelessness that the trouble came about.

Looking now for the map given him by General Dupree, which was to mark out for Hal the safety zones in the allied lines, the lad was unable to find it.

Frantically he explored his pockets, the while keeping one hand on the wheel. He could not find the map.
