French soldiers were becoming more numerous.

At times an entire French regiment could be seen marching along a road.
"At the next station," announced Captain Ribaut, "we shall find ourselves at the end of our rail journey.

We are nearing the front.

If you are interested, gentlemen, there goes one of our French airplane squadrons on its way to the front." Instantly all four Americans were craning their necks at the windows.
High in the air, the French aircraft in flight looked as graceful as swallows on the wing.
"They are battleplanes," explained Captain Ribaut further.

"Some of the Hun flyers are almost sure of a tumble this afternoon." When the American party alighted at the last station on the line, and looked back, they beheld long trains of freight cars coming slowly along.
