To the opening in the church wall came a nurse. She walked with short, uncertain steps and leaned against the ragged edge of the wall, with one arm along its stone for support. Her face was white and drawn, and for a moment she closed her eyes and breathed deeply of the dust-laden air. The fat private on the stone, a score of feet away, studied her approvingly. She was slight of form and her hair beneath the cap was of gold, a little tarnished. He waited for her eyes to open, then hailed her genially as he waved at a tangle of camions and ambulances now blocking the bridge.

"Worse'n fair week back home on Main Street, hey, sister?"

But she did not hear him, for a battered young second lieutenant with one arm in a sling had joined her from the dusk of the church.

"Done up, nurse?" he demanded.

"Only for a second. We just finished something pretty fierce."

She pointed back of her, but without looking.

"Why not sit down on that stone?"

He indicated a fallen slab at her feet. She looked at it with frank longing, but smiled a refusal.

"Dassent," she said. "I'd be asleep in no time."

"Cheer up! We'll soon finish this man's job."
