Jack gulped something down, and then blurted out:
"Did you mention my name at all, Tom?"
"Yours was the only one I had in mind; and Jack, rest easy, you're going along with me to-night to glimpse the lights of Metz!"
CHAPTER XIV
OFF ON A DARING MISSION
The two air service boys fell to talking earnestly concerning what they should take with them, and how to study a map which their captain had promised to put in Tom's hands immediately.
This was not of the ordinary kind, but so definitely marked for just such an emergency that even a novice could probably find his way to Metz, granting that he possessed the necessary qualifications of an air pilot.
Presently a messenger came with a package for Tom. This proved to be the chart from the commander of the air squadron. Tom was to make as good a copy as was in his power, for the original was too valuable to risk losing.
Jack understood that there were several reasons for having Tom do this. In the first place his work on the chart would familiarize the young aviator with its every detail, and fix things firmly in his mind. Then again, if they were lost, and never returned, the priceless chart for night voyaging over the enemy's lines would be at least safe.
Daring men had gone forth on similar desperate errands before then, and had never been heard from again. It is the fortune of war. Those who indulge in enterprises that border on the sensational must always expect to sup with deadly peril.
