So it went. For every German spy or would-be spy in America, there was an agent of the Secret Service, equally resourceful, and more likely to succeed, because, no matter how clumsy his adversary seemed, he never made the mistake of underrating him. "Stupid Yankees," von Papen had called us, while he went about his plotting with child-like faith in his skill at hiding. "Stupid Germans," the Secret Service might have retorted, as it skillfully uncovered all his plotting and sent him back to his Kaiser, where his stupidity was more appreciated. But it took many months of patient, unceasing work, and far the greatest part of it was dull, hard, steady grind. Rarely was there any excitement for the industrious government agents, and more rarely was there any glory, for the work had to be kept secret. Trailing, watching, studying, thinking, always putting two and two together and often finding that they made five instead of four; through day and night, through sun and storm, the officers whose duty it was to catch the spy before he could harm America worked steadily on. That is why America won at home just as she won abroad. Had not the silent army in the United States fought so unceasingly and so skillfully, the army in France would have been paralyzed. When you think of the Great Victory, remember those quiet, unknown men and women at home who did so much to help win it, and give full credit to the Secret Service. ROGER WILLIAM RIIS.
