General Vaugirard walked a little distance up the road, climbed into an automobile and, standing up, looked a long time through his glasses.

Lannes, who had been resting on the grass, approached the general and John saw him take a note from him.

Then Lannes went away to the _Arrow_ and sailed off into the heavens.

Many other planes were flying over the French army and far off in front John saw through his own glasses a fleet of them which he knew must be German.
Then he heard a sound, faint but deep, which came rolling like an echo, and he recognized it as the distant note of a big gun.

He quivered a little, as he leaned against his motor cycle, but quickly stiffened again to attention.
