It is a history book. Along the old Roman road that crosses the rolling hills from the upper waters of the Marne to the Meuse, a soldier of France was passing in the night. In the broader pools of summer moonlight he showed as a hale and husky fellow of about thirty years, with dark hair and eyes and a handsome, downcast face. His uniform was faded and dusty; not a trace of the horizon-blue was left; only a gray shadow. He had no knapsack on his back, no gun on his shoulder. Wearily and doggedly he plodded his way, without eyes for the veiled beauty of the sleeping country. The quick, firm military step was gone. He trudged like a tramp, choosing always the darker side of the road. He was a figure of flight, a broken soldier. Presently the road led him into a thick forest of oaks and beeches, and so to the crest of a hill overlooking a long open valley with wooded heights beyond. Below him was the pointed spire of some temple or shrine, lying at the edge of the wood, with no houses near it. Farther down he could see a cluster of white houses with the tower of a church in the center. Other villages were dimly visible up and down the valley on either slope. The cattle were lowing from the barnyards. The cocks crowed for the dawn. Already the moon had sunk behind the western trees. But the valley was still bathed in its misty, vanishing light. Over the eastern ridge the gray glimmer of the little day was rising, faintly tinged with rose. It was time for the broken soldier to seek his covert and rest till night returned.
