Out of all the investigations of the Government arose a card index of every man that Rintelen and Lamar had seen during the four months from April 3 to August 3, 1915, of every hotel they had visited, of practically every telephone call they had made and every telegram sent or received, of nearly every dollar they had had and spent. Thousands upon thousands of these cards were made and filed. They convicted both men. The Government indicted Rintelen, Lamar, Buchanan, Fowler, Martin, Schulteis, and a man named Monnett, for conspiracy to violate the Sherman Act in the operations of Labour’s National Peace Council to restrain our foreign trade. Rintelen, Lamar, and Martin were convicted. The rest got the benefit of a very slim doubt, except Frank B. Monnett, the farmer attorney-general of Ohio, whose reputation in the early suit of Ohio to oust the Standard Oil Company from the state had been used as “stage setting” by Martin. He was freed by the Court before the jury was sent out to deliberate. The convicted men got the limit of the law--one year in jail. Rintelen was likewise indicted for perjury in his application for a passport as Edward V. Gates, and again for another crime against our laws. He was convicted on both charges, and sentenced to several months’ imprisonment on each. No one realized better than the judges who sentenced him how inadequate these punishments to expiate his crimes. But the laws under which Rintelen was convicted--and they were the only laws under which his acts (all committed before our entry into the war) could be questioned--were enacted in times of peace, when no one dreamed of the world conflict or could have imagined how it would affect us when it came. Rintelen has completed serving time on the first of his three sentences, and has the other two still to serve. The Tiger of Berlin is securely caged, and not likely soon to be again at large. CHAPTER IX THE AMERICAN PROTECTIVE LEAGUE On going to war with the great masters of spy craft last year, the United States had only a handful of secret service men to guard its internal frontier. Within our borders were a million and a half men and youths who were enemy aliens. Not all of them hostile, it is true; but all potentially dangerous because great national organizations existed--even shooting societies--through which German influences might reach in a few hours or days. And in every centre of population there were captains and field marshals of German intrigue, supplied with unlimited money, to appeal to their feelings and to lead them should a chance come to strike.
