Further light was thrown upon political conditions by the investigations of the "star routes." These were routes in the South and West where mails had to be carried by stage lines, and were under the control of the Second Assistant Postmaster-General, Thomas J. Brady. Rumors had been common for some years that they were a source of corruption. Garfield's Postmaster-General, Thomas L. James, had already made a reputation as the reform postmaster of New York, and he set himself to investigate the reports. Among other things it was discovered that a combination of public men and contractors had succeeded in raising the compensation on 134 star routes from $143,169 to $622,808, dividing the extra profits among themselves. Brady and Senator Dorsey, the active agent in the campaign in Indiana, were accused of being in the "ring" and were indicted on the ground of conspiracy to defraud the government. Brady attempted to block the investigation by threatening Garfield with an exposure of the campaign methods, and when the threat failed he made public a letter from the President to "My dear Hubbell," chairman of the Congressional Committee, similar to that which Conkling had earlier published. The trials of the conspirators dragged on until 1883 and resulted in the acquittal of all the accused except one of the least important. Yet some good was accomplished, for the ring was broken up. Dorsey retired from public life, and renewed attention was drawn to the need of better federal officials. During the course of the trials, the country was shocked by the assassination of the President on July 2, 1881, at the hands of a disappointed office seeker named Guiteau. Despite a strong constitution Garfield grew slowly weaker and died on September 19. The catastrophe affected the country the more profoundly because of its connection with the factional quarrel in the Republican party and because, following the recent murder of the Russian Czar, it seemed to show that democratic government was no guarantee against violence.[4]
