We rode on till we had gone eighteen miles.

"Here is our station."

I didn't know we were there. Our Poste de Secours was simply one more hole in the ground, an open mouth into an invisible interior—one more mole hole in honeycombed ground.

We entered the cave, and something hit my face. It was the flap of sacking which hung there to prevent any light being seen. We walked a few steps, hand extended, till it felt the second flap. We stepped into a little round room, like the dome of an astronomical observatory. It was lit by lantern. Three stretcher bearers were sitting there, and two chaplains, one Protestant, one Roman Catholic. The Protestant was a short, energetic man in the early forties, with stubby black beard and excellent flow of English. The Roman Catholic, Cleret de Langavant, was white-haired, with a long white beard, a quite splendid old fellow with his courtesy and native dignity. These two men, the best of friends, live up there in the shelled district, where they can minister to the wounded as fast as they come in from the trenches. Of one group of thirty French stretcher bearers who have been bringing wounded from Dead Man's Hill to this tunnel, where the Americans pick them up, ten have been killed.

We went out from the stuffy, overcrowded shelter and stood in the little communicating trench that led from the Red Cross room to the road. We were looking out on 500,000 men at war—not a man of them visible, but their machinery filling the air with color and sound. We were not allowed to smoke, for a flicker of light could draw fire.

We were standing on the crest of a famous hill. We saw, close by, Hill 340 and Dead Man's Hill, two points of the fiercest of the Verdun fighting. It was the wounded from Dead Man's Hill for whom we waited. Night by night the Americans wait there within easy shell range. Sometimes the place is shelled vigorously. Other nights attention is switched to other points.

"I shouldn't stand outside," suggested one of the stretcher bearers. "The other evening one of our men had his arm blown off while he was sitting at the mouth of the tunnel. He thought it was going to be a quiet evening."

But the young American doctor liked fresh air.

It was a wonderful night of stars, with a bell-like clarity to the mild air and little breeze stirring. A perfect night for flying. We heard the whirr of the passing wings—the scouts of the sky were out. Searchlights began to play. I counted eight at once, and more than twenty between the hills. Sometimes they ran up in parallel columns, banding the western heaven. Sometimes they located the knight errant and played their streams on him at the one intersecting point. Again the lights would each of them go off on a separate search, flicking up and down the dome of the sky and rippling over banks of thin white cloud.

Star lights rose by rockets and hung suspended, gathering intensity of light till it seemed as if it hit my face, then slowly fell. The German starlights were swift and brilliant; the French steady and long continuing.
