That lesson was never impressed more forcibly than by a French officer of whom a visitor from America asked, "Did I understand that you had lost three sons?" "Yes, sir, and two brothers," was the proud reply. "How you must hate the Boche," remarked a bystander. "No, no," was the instant reply, "not hate; just pity, sir; pity, but not hate. Hate, you know, is an excessive emotion, sir; and no one can do effective work if he spends his vitality in an excess of emotion. No," he concluded, "we cannot hate; we cannot work if we burn up ourselves inside. Pity, sir; pity. 'They know not what they do.' That's the idea. And they don't." The same lesson of self-restraint was taught by Marshal Foch in his words to the soldiers of France. He urged them to keep their eyes and ears ready and their mouths "in the safety notch"; and he told them they must obey orders first and kick afterwards if they had been wronged. He said, "Bear in mind that the enemy is your enemy and the enemy of humanity until he is killed or captured; then he is your dear brother or fellow soldier beaten or ashamed, whom you should no further humiliate." He told them that it was necessary to keep their heads clear and cool, to be of good cheer, to suffer in silence, to dread defeat, but not wounds, to fear dishonor, but not death, and to die game. Because so many of the soldiers under him heeded this wise admonition, they did not waste their precious strength on useless and harmful emotions, but they were ever ready to go to their task, with the motto of their division, "It shall be done." What a blessing it will be to the world that millions of young men were trained in France to repress hurtful emotion, to exercise self-restraint--which may be defined as the act or process of holding back or hindering oneself from harmful thoughts or actions. And what a wonderful thing it will be if the lesson is passed on to us, so that we shall not be like the torrent that wastes its power by rushing and brawling over the stones, all to no purpose, but like the harnessed stream whose energy is made to turn the wheels of factory and mill. For only guarded and guided strength is useful and safe. II EFFACING SELF "Every man that falls must understand beforehand that he is a dead man and nothing can save him. It is useless for him to cry out, and it may, by giving the alarm, cause the enterprise to fail." This was the message to his men of the officer to whom Napoleon committed the capture of Mt. Cenis. The historian tells us that at one point in the ascent of a precipitous track, three men fell. "Their bodies were heard bounding from crag to crag, but not a cry was heard, not a moan. The body of one hero was recovered later. There was a smile on his lips."
