"Good-bye," said Lannes, extending his gloved hand. "We're comrades, John, and I hope sometimes to turn your little fraternity of three into a brotherhood of four. Tell the Englishman, Carstairs, that France and England together can't fail."

"He'll think it mostly England."

"If we only win, let him think it."

Lannes stepped into the machine, it was shoved forward, then it rose gracefully into the air and flew off in the usual spirals and zigzags toward the east, where it was soon lost in the darkness. John gazed toward the point, where he last saw it. It seemed almost a dream, that flight of his with Lannes, and the fight with the Taubes, and the Zeppelin. He was on the ground now, and the coming battle would be fought on the solid earth, as man had been fighting from time immemorial. He was about to return to his blanket when a glad voice called to him and a figure emerged from the dark.

"Mr. Scott," came a pleasant voice. "And you were not drowned after all! I thought that I alone escaped!"

It was Weber, paler than usual, but without a wound. John's surprise was lost in gladness. He liked this man, whose manners were so agreeable, and he had mourned his death.

"Mr. Weber," he said, shaking hands with him, "it's I who should say: 'and you are not dead?' We thought you were drowned under the automobile. Mr. Wharton, Mr. Carstairs and myself escaped uninjured although we had a hard time afterward with the Germans. How did you manage it?"

"I was under the automobile, and I did come near being drowned, but not quite. I'm a good swimmer, but I was caught by a strap. As soon as I could disengage myself I swam rapidly down stream under water, came up in the shadow, and crawled among some bushes on the bank. I saw the Germans ride into the river, search the opposite shore, and after a while go away. Then I emerged from the bushes, walked more hours than I can count, and you see me here. I've brought information which I think of value, and I'm on my way now to give it to high officers."

John shook hands with him again. Weber's manner, at once frank and cheerful, invited confidence.

"Providence seems to watch over all four of us," he said. "It's quite certain that none of us will ever meet his death by drowning."
