“Who gave him permission to go out there? Is he deserting?”

THEY MARCHED STRAIGHT FOR THE AMERICAN LINES.

“Indeed he isn’t, Sir,” answered Ned. “I guess he must be trying some experiment, or looking for bugs.”

“Well it’s likely to be his last experiment,” was the grim comment, “and about all he’ll find will be bullets. Ah, I was afraid so. Look, they are going to capture him!”

As he spoke the Americans, crouching in their trench, saw three German soldiers leap out of their ditch and advance toward the professor. But the latter did not seem in the least afraid. He walked on, for a moment not observing his enemies, who were approaching from one side. Then suddenly he noticed them.

But he did not run, nor did he show any sign of fear, and then the most unexpected thing happened. The Germans suddenly dropped their rifles. Up in the air went their hands, and then they turned and marched straight for the American lines, the professor following behind, and fairly driving them on in some mysterious way. He had made a most unexpected capture.
