Tired though he certainly was, the young aviator could not think of seeking rest. He managed to get a bite to eat, for he was very hungry after his frigid experience aloft. Then with his glasses betook himself to a convenient place of observation, from which he could watch much that was going on, particularly in the regions above.

But the Teutons had virtually given up all attempts to fight for air supremacy on that particular day. They had been sadly outnumbered and outclassed in most of the fights by the British, French and American fliers with whom they had found themselves faced.

Of course the story was not all onesided. There had been times when it was the Boche flier that proved to be the more skillful; and several French pilots had been dropped. One of these had fallen in the open space between the hostile lines. He was only wounded it was seen, and desperate attempts were made by his comrades to sally out and rescue him.

Three times did this happen, only to have the German guns open on them with telling effect. Dozens of men had fallen solely through their desire to save the gallant air pilot. Twice did Teutons venture forth with the evident intention of making him a prisoner, only to recoil before the blast of deadly machine-gun fire that blazed forth in their faces.

Finally the Germans, as if furious at their losses, turned their machine-guns on the wreckage of the French plane, and fairly riddled both machine and pilot with balls.

Of course Tom easily picked out the big observation Caudron in which, as he knew, Jack was doing duty just then. Once he thought something serious had happened to it when he saw the plane rock violently, as if about to collapse; but it immediately righted again. Tom guessed it was one of those high explosive shells that were still coming periodically from the Teuton rear that had passed so close as to cause the motion.

His heart had jumped into his throat with a sudden fear, lest Jack’s initial experience in hovering above a battlefield be also his last. Then he felt a wave of relief pass over him when he saw that the danger had passed; for the observation plane was moving majestically onward as before, and just as steadily.

As the afternoon waned the battle gradually ceased. The Germans had found out that their foes were of a mind to hold on to their recent gains with a death-grip that nothing could shake off. The French had taken their second wind, so to speak and were once more “in the running.”

Then Jack and his companion came down again, making a safe landing. Tom was on hand to greet his chum as the latter rather unsteadily alighted; for being up in a rocking plane for hours is apt to make any one feel a bit “groggy.”

“Well, how did you like it?” was Tom’s first question.
