Roosevelt acted on the principle that the office holder who swears to carry out a law must do this without hesitation or demur. If the law is good, enforcing it will make its goodness apparent to everybody; if it is bad, it will become the more quickly odious and need to be repealed. Roosevelt enforced the Civil Service Law with the utmost rigor. It called for the examination of candidates for office, and the examiners paid some heed to their moral fitness. Its opponents tried to stir up public opinion against it by circulating what purported to be some of its examination papers. Why, they asked, should a man who wished to be a letter-carrier in Keokuk, be required to give a list of the Presidents of the United States? Or what was the shortest route for a letter going from Bombay to Yokohama? By these and similar spurious questions the spoilsmen hoped to get rid of the reformers. But "shrewd slander," as Roosevelt called it, could not move him. Two specimen cases will suffice to show how he reduced shrewd slanderers to confusion. The first was Charles Henry Grosvenor, an influential Republican Congressman from Ohio, familiarly known as the "Gentle Shepherd of Ohio," because of his efforts to raise the tariff on wool for the benefit of the owners of the few thousand sheep in that State. A Congressional Committee was investigating the Civil Service Commission and Roosevelt asked that Grosvenor, who had attacked it, might be summoned. Grosvenor, however, did not appear, but when he learned that Roosevelt was going to his Dakota ranch for a vacation, he sent word that he would come. Nevertheless, this gallant act failed to save him, for Roosevelt canceled his ticket West, and confronted Grosvenor at the investigation. The Gentle Shepherd protested that he had never said that he wished to repeal the Civil Service Law; whereupon Roosevelt read this extract from one of his speeches: "I will vote not only to strike out this provision, but I will vote to repeal the whole law." When Roosevelt pointed out the inconsistency of the two statements, Grosvenor declared that they meant the same thing.
