No Tom yet! Things certainly were taking on a dark hue, and it looked as though desperate trouble might be in store for the two chums. Jack almost believed he could see dancing lights coming along what might be a road. He looked again, and no longer had any doubt on that score.

"Well, a fellow can die only once, and after all what does it matter whether he meets his end by falling ten thousand feet from the clouds or in trying to hold off an angry mob of Teuton soldiers and citizens of Metz who are in sympathy with the methods of the Kaiser?" Jack's reflections served to give him courage.

There was the leading one of the mob, starting across the dimly lighted field! Jack set his jaws hard, and determined that he would wait until the other had come close up. Ammunition was much too precious to be wasted without results following.

He was soon glad he had made such a sensible resolution, for as the runner drew closer something familiar about his figure and methods of leaping told Jack it was none other than Tom.

"Get aboard in a hurry, after you've given the propellers a swing!" cried Tom, almost breathless himself after such a sharp run. "I've got what I wanted."

He was already in his place with his hand on the control.

"Tell me when, Tom!" sang out Jack.

"Cut loose!" ordered the pilot.

The propellers spun, and the motors commenced their furious throbbing. Jack swung aboard, and at once the plane started to roll along the field, even as men appeared, bursting into view on one side, and shouting harshly as they realized how close they had come to catching those they sought.
