When the airmen trailed in toward noon on that October day, first, rumors reached Tom and Jack, and then came the plain story connected with Harry's extraordinary conduct on that wonderful morning.

Other pilots said the boy seemed to be possessed of a spirit such as they had never known him to show before. He hunted out the Boche wherever he could find him, forced him to give battle, and then simply played with him, no matter if he chanced to be one of the best-known German aces.

Two he had sent down in flames, for which he would receive due credit; and there were reports that he had also made as many more drop to the earth in a condition of impotence.

"Why," said a pilot who recounted some of these happenings to the air service boys, "Harry seemed possessed of a reckless spirit that will be the death of him yet unless he curbs it. He'll soon have the entire Boche escadrille on his tail, crazy to fetch him down. And if he keeps up this sort of work and lives, he'll soon make our leading ace look to his laurels."

When Harry came in finally he looked flushed, but triumphant.

"What's all this we hear about your carrying-on this morning?" demanded Jack, almost immediately.

"Oh, I just made up my mind that I'd got to have a special day of it, that's all," replied the other carelessly. "They wouldn't let me go along with you chaps, and I had to do something to let the ugliness get out; so I put it up to Fritz. And, say, I've had a glorious time, too."

He refused pointblank to tell them anything more at the time, so they had to pick up all their information through other channels; but then it was not so hard to do that, since nearly every working aviator had taken note of Harry's remarkable work that morning.

Then came the afternoon.

Both Tom and Jack might have considered that time dragged, only for the fact that they could pass the hours in a pleasant fashion. Tom managed to get over to the field hospital to see his wounded friend, Fred Lincoln. And, really, he did spend as much as ten minutes trying to cheer that individual up, for Fred had lost an arm, and was feeling blue over his future home-going to his young wife.
