Troy was anxious, for he was not sure that Mr. Belknap's influence might not be sufficient to detach him from his job on a temporary mission; but long experience in dealing with parents made him assume a greater air of coolness as his fears increased. "Well, you see, father, so many other chaps have taken advantage of the lull to go off on leave that if I asked to be detached now--well, it wouldn't do me much good with my chief," he said cunningly, guessing that if he appeared to yield his father might postpone action. "Yes, I see," Mr. Belknap rejoined, impressed by the military character of the argument. He was still trying to get used to the fact that he was himself under orders, and nervous visions of a sort of mitigated court-martial came to him in the middle of pleasant dinners, or jumped him out of his morning sleep like an alarm-clock. Troy saw that his point was gained; but he regretted having proposed the Capucines to his father. He himself was not shocked by the seeming indifference of Paris: he thought the gay theatres, the crowded shops, the restaurants groaning with abundance, were all healthy signs of the nation's irrepressible vitality. But he understood that America's young zeal might well be chilled by the first contact with this careless exuberance, so close to the lines where young men like himself were dying day by day in order that the curtain might ring up punctually on low-necked _revues_, and fat neutrals feast undisturbed on lobster and champagne. Only now and then he asked himself what had become of the Paris of the Marne, and what would happen if ever again----But that of course was nonsense.... * * * * * Mr. Belknap left for Italy--and two days afterward Troy's ambulance was roused from semi-inaction and hurried to Beauvais. The retreat from St. Quentin had begun, and Paris was once again the Paris of the Marne. The same--but how different!--were the tense days that followed. Troy Belknap, instead of hanging miserably about marble hotels and waiting with restless crowds for the communiqués to appear in the windows of the newspaper offices, was in the thick of the retreat, swept back on its tragic tide, his heart wrung, but his imagination hushed by the fact of participating in the struggle, playing a small dumb indefatigable part, relieving a little fraction of the immense anguish and the dreadful disarray.
