The boys walked about, under the guidance of a non-commissioned officer who had been detailed for the purpose, inspecting the new aeroplanes arriving in cases from the factory, those already assembled, and a number which had been tested. They saw several machines which had been badly damaged, some by reason of defects and others by unskillful handling by novices. A number of aspiring candidates were being given practical instruction in aviation by experienced men. None of the recruits were permitted to take charge of a machine until after several flights had been made in company with their instructors. Then they were given charge of a machine and permitted to make their first flight unaccompanied. Jimmie declared that his fingers itched to have charge of one of the larger machines intended for attack. The small scouting machines did not interest him.

The large planes were built with space for mounting a machine gun, with room for its operator and a supply of ammunition. Above the gunner's seat the pilot was located, where he could get an excellent view of his surroundings and direct the craft as desired by the gunner.

A bugle call attracted their attention. Their guide announced, through Francois, who acted as interpreter, that lunch was ready.

"I declare, I nearly forgot I was hungry!" asserted Jimmie.

"It's mighty interesting!" agreed Ned. "But I don't think they have anything the better of our little old Grey Eagle, when it comes to ease of handling and speed. We can show any of them a clean pair of heels when that engine gets nicely smoothed up!"

"Right you are, Scout!" Jimmie returned vigorously. "And they haven't any of them got anything on me when it comes to eating! Advance, Comrades!" he continued with a laugh. "Let us attack the cold cure!"

Before the boys had devoured the splendid luncheon provided for them under the direction of the commander, they were again visited by their recent passenger. He had been very busy during the short interval and, as the boys later learned, had gotten in touch with the entire battle front by means of telegraph and telephone. Orders had been issued with whirlwind promptness, and information received, to be glanced at only once ere it was safely stored in the master mind.

Long after their visit the boys learned to value the ability of the man whom all France was depending upon to bring her out of the terrible crisis in which she was then placed.

After inquiring if their wants had been properly supplied, the General approached Ned on a subject that the lad had anticipated would be mentioned. It was one that he dreaded.
