From a front room overhead Warner and Sister Eila were leaning out and watching the lively spectacle along the river.

"It looks to me," he said, "as though the Germans were in the cement works.... By George! They are! The yards and quarries are alive with their cavalry! Look! Did you see that shell hit the stone crusher? There goes another. The big chimney on the Esser Works is falling—look!—down it comes! Our gunners have knocked it into dust!"

Another section of artillery came plunging into view across the meadows, the drivers spurring and lashing, the powerful horses bounding forward, and the guns jumping and bouncing over the uneven ground.

It was like a picture book—exactly what the layman expects of a battle—a wide, unobstructed view over a flat green meadow, artillery at a gallop with officers spurring ahead; brilliantly uniformed cavalry arriving in ever-increasing squadrons, some dismounting and deploying, others drawn up here and there under serried thickets of lances. But there was no smoke, only a dusky, translucent haze clinging for a moment to the gun muzzles; no enemy in sight save for a scrambling dot here and there among the quarry hills where, from the cement works, a cloud of dust rose and widened, veiling the trees and hillsides.

For a while the lively rattle of the fusillade continued, but in a few minutes a six-gun battery arrived and went into ear-splitting action, almost instantly extinguishing the German fire from the quarry. A few more ragged volleys came, then only dropping shots from their carbines as the hussars rode forward and broke into a gallop across the quarry bridge.

More cavalry was arriving all the while, dragoons and chasseurs-à-cheval, all riding leisurely toward the quarry. More artillery was coming, too, clanking and bumping up the road, a great jolting column of field batteries, not in a hurry, paying little attention to the lively proceedings across the river, where the German cavalry was retreating over the rolling country toward the eastern hills and the blue hussars were riding after them.

The artillery passed the school and continued on toward Ausone. Behind them came infantry with their swinging, slouchy stride, route step, mildly interested in the doings of the cavalry in the meadow, more interested in the Sisters of Charity leaning from the schoolhouse windows and the excited children crowding at the open door.

Not very far beyond the school a regiment turned out into a stubble field and stacked arms. Other regiments swung out east and west along the Route de Saïs, stacked arms, let go sacks, and went to work with picks and spades.

More artillery rumbled by; then came some engineers and a pontoon train which turned out toward the river opposite the school after the engineers had opened a way through the hedge stile.

Sister Eila and Warner had returned from the upper story to stand on the doorstep among the children.
