In every direction bicycle and motor cycle messengers were speeding, north and south on the Saïs road, west toward Dreslin by the mill, eastward over cow-paths and sheepwalks, and across the pontoons, or by the school highway and quarry bridge, southeast toward a road crowded with motor lorries, and through that gap in the foothills which narrows into the Pass of the Falcons.

Warner, leisurely buttoning his waistcoat, stood looking out of the window at the scenes passing under the plateau, and listening with the greatest interest to Halkett's comments on these preliminaries for a campaign about to open.

"Then, in your opinion, it is invasion?" he said.

Halkett nodded:

"I can make nothing else of this movement, Warner. Our General, Pau, is at Nancy. What you see down there is part of a perfectly complete and coherent army, and it is certainly moving on the Vosges passes.

"Metz, Strassburg, Colmar, lie beyond; our alpinists are swarming around the Donon. Under it lie the lowlands of Alsace and Lorraine.

"Already we have seized the pass of Saales; Thann and Danemarie are menaced; the valley of the Bruche lies before us, Saarburg and the railroad to Metz invite us.

"Does it not all seem very logical, Warner?"

"It sounds so."

"It is good strategy. The logic is sound logic. If we carry it through, it will be applauded as brilliant strategy.
