"Philippa, Halkett is here somewhere."

"Oh!" she exclaimed happily.

"He's here with his machine—an aëroplane of sorts—Bristol, I believe. No doubt he'll come up to the house when he has a chance. I suppose Sister Eila has gone up to tell Gray."

They had strolled around to the eastern parapet and now stood looking out over the tree tops.

"What has happened at Ausone?" she asked. "The cannon have stopped firing."

"I saw Ausone burning from Vineyard Hill. It's all knocked to pieces, Philippa. What I think has happened is this: troops from Verdun and Toul—perhaps from Chalons—have entered Ausone in time to save the fort. I suppose our infantry are intrenched along the Récollette and that there is going to be more fighting in Ausone Forest, which must be full of Germans."

"You don't think they'll come here?"

"I don't know. The army which you see below us everywhere in the valley is probably on its way to invade Alsace. D'Aurès thinks so. I suppose this line will be defended. We shall hear more cannonading, I fancy. Anyway, they are digging trenches to fall back on."

"Where?"

"Along the Récollette."
