CHAPTER XXIV
TROUBLOUS TIMES FOR JACK

The men bearing the lanterns came closer, Jack saw, as he himself scurried amidst the bushes seeking a hiding-place.

"Guess that Potzfeldt must know that planes can drop down on his big open field," the youth muttered to himself. Then as a new idea flashed through his brain he continued: "Whee! I warrant you now that ours wasn't the first airplane to land there. Sometimes maybe the spy he wants to send back of the French lines gets aboard right here, with his little cage of homers."

Presently loud exclamations told that the men had discovered the marks of the arriving and departing Caudron machine. Jack could hear them exchanging remarks about it, in German of course. Then he saw one of the trio start back toward the house. He was half running, as though much excited. Jack jumped to a conclusion.

"Say," he said to himself, in a whisper, as though even the sound of his own voice might be company for him, "now that must have been Carl Potzfeldt himself. What's he making for the house with a hop, skip and jump for? Perhaps one of his sharp-eyed men has told him there are marks of small shoes around; and old Carl got a sudden suspicion something tremendous has happened."

The master-spy came back again. He was now accompanied by two others, and Jack saw by their uniforms that they were members of the general's staff.

All were talking earnestly, Potzfeldt, Jack imagined, telling them some story concerning Bessie and her mother, in which he figured as a noble man, trying to save Mrs. Gleason from the wiles of some American fortune hunter, into whose hands he now feared she and her daughter had fallen.

"My! but he's wild!" chuckled the hidden observer. "He realizes that the two American boys have been too much for his scheming after all. Guess he must have had a suspicion all along we'd break up his game. That'd account for his plotting with the other spy to have our planes meddled with, so we'd meet with some terrible accident that would remove us from his path."

Jack was really enjoying himself. It did him good to hear Potzfeldt raging around, and spluttering as though his rage half choked him.
