Admiringly the boys gazed at the inspiring spectacle of so great a number of aeroplanes in the air at one time. Their interest knew no bounds. Here was an opportunity for gaining much information.

All too soon was the Grey Eagle in the vicinity of the camp. Its coming was detected by some of the air scouts almost as quickly as the camp had been located by the boys. Several at once advanced and hovered near, in an effort to learn the identity of the visitor.

Proceeding directly to a spot indicated by the General, Ned brought the machine gracefully and easily to the ground. A group of aviators and officers quickly surrounded them and assisted the passengers to alight. Recognizing the General, they set up a hearty cheer.

Turning to an officer in his immediate vicinity, the General spent several minutes in animated conversation. Apparently he was questioning that individual closely concerning important matters.

At length he turned to the boys with a smile on his face.

"You may rest easy on one score, at least," he said. "Your friend, The Rat, made his way into Flanders about half an hour ago!"

"How do you know?" asked Jimmie incredulously.
