Tom hurried to join the commander of the Lafayette Escadrille. He had taken a great fancy to the gallant man, and believed this feeling was in a measure returned. Jack continued to sit and mope. He really felt slighted to be left out when so much thrilling work was being done.

He had put away the well-thumbed scrap of paper with its mysterious lines of warning, for the time being Bessie and all her troubles passing from his mind. Jack was now full of his own affairs. He found himself growing a bit discontented because thus far he had been allowed to do so little for the cause, when his heart was full to overflowing with a desire to assist.

There were aviators going and coming all the time, and surely many of them did not excel him appreciably in talents. Why did not those in charge find something for an ambitious pilot to do? He was striving daily to master the weak spots in his education; and had not the captain himself assured him he was doing bravely? He turned to cast an occasional look toward the spot where Tom and the commander of the air squadron still talked earnestly. Yes, something was certainly "on tap," as Jack expressed it, for he saw the other carefully examining a bit of paper his companion had evidently placed in his hand.

Jack began to be interested. Perhaps after all it might turn out to be something quite different from what Tom had anticipated. Had the captain simply wished to notify the other to be ready to answer a call on the following morning, surely he need not have taken all this time; nor would he have given Tom that paper, undoubtedly carrying explicit instructions.

How the minutes dragged! Jack thought it an eternity before he saw Tom and the captain separate. He was glad to notice that his chum once more headed in the direction of the spot where they had been seated on a bench back of the long row of frame buildings used for permanent hangars at the Bar-le-Duc aviation field.

Yes, Tom had evidently been told something that pleased him very much. His smile admitted the fact, and Jack knew by now just how to read the face of his comrade so as to get a good idea of what was passing in his mind.

"Looks like good news, Tom," he cried out, for motors were rattling and throbbing, mechanicians and helpers, as well as pilots, calling to one another, and all manner of sounds combining to make a great racket.

Tom shrugged his shoulders in a non-committal way, which might mean a whole lot, and again might express a small fraction of disappointment.

"Yes, I've been given a job, if that's what you mean," he admitted, as he dropped down once more on the bench alongside Jack, and threw one leg over the other.

"More fighting to-morrow, possibly?" queried Jack, anxiously. But he found his curiosity further whetted when Tom shook his head in the negative.
