The next moment the Cuirassier was gone and General Delisle had taken Warner's arm with a quiet smile and was leisurely sauntering back toward the music room.

"It was very friendly of you, Mr. Warner—may I add, very sagacious? But that is like an American. We French feel very keenly the subtle sympathy of—" he laughed—"neutral America."

"Are these papers of real importance, General?—Is it proper of me to ask you such a question?"

"They are of—overwhelmingly vital importance, Mr. Warner."

"What!"

The General halted, looked him pleasantly in the eyes:

"The most vitally important information that I have ever received during my entire military career," he said quietly. "Judge, then, of my gratitude to you. I cannot express it. I can only offer you my hand—with a heart—very full."

They exchanged a firm clasp. As they went into the music room, Count Cassilis, who had seated himself at the piano, and who was running over a few minor scales, turned and looked at them, rising slowly to his feet with the other officers when the General entered. He had his monocle screwed into his right eye.

The cannonade had now become noisy and jarring enough to interrupt conversation, and it was plain to Warner that French batteries somewhere along the Récollette had opened.

Out on the terrace he could see aëroplanes in the northeastern sky, no doubt trying to find the range for the French batteries. They were very high, and the clots of white appeared and dissolved far below them.
