Captain Le Blanc turned and glanced questioningly at Jacques who stood nearby. The young Frenchman nodded his head slightly.

"These are the ones, General," said the captain, facing again the man who had questioned him.

"Very good," exclaimed the general, a keen-eyed soldier with white hair and a white mustache. "They are friends of yours I take it?" he remarked to Jacques.

"Yes, sir," replied Jacques with a prompt salute.

"Young men," said the general now addressing Leon and Earl, "I have a mission to be performed; it requires the services of an experienced aviator and we have decided that it is best for him to be accompanied by two men. It is dangerous but it is necessary. We have chosen you three young men from among many and we rely on you to carry the enterprise through to a successful conclusion.

"You will start at dawn; Private Dineau will be the aviator and he will have as aides the brothers Platt. You will be conducted to the machine you are to use and as dawn is not far distant I advise you to prepare yourselves at once. Good luck to you."

He turned away and the three boys, realizing that they were dismissed, immediately withdrew. Captain Le Blanc's orderly followed them.

"I will conduct you to your machine," he announced and set out at once, closely followed by the three young soldiers. Back from the front they walked, proceeding through the winding maze of communicating trenches. Few words were spoken until they emerged from the trenches entirely and came to the open road.

A small motor-car with a chauffeur seated at the wheel stood near the entrance to the trench.

"For us," announced the orderly and straightway climbed aboard.
