The reader has been informed of the inspiriting effect produced upon Sheriff McCleary by military protection. One of the first results thereof was the enlistment of a corps of deputies to take the place of the Homestead police, the latter officials being so thoroughly in sympathy with the strikers that they devoted their attention chiefly to the apprehension of non-union men who happened to stray out of the works. The sight of a non-unionist was always sufficient to incite an uproar and on several occasions riotous demonstrations were caused by the appearance on the streets of men who had the hardihood to leave the mill and walk abroad. The Sheriff kept adding to his force of deputies according as the military guard was reduced, until when the last of the troops left Homestead, there were enough civil officers employed to deal with any ordinary disorder. The congressional investigation which was begun at Pittsburgh was resumed at Washington on July 23. Robert and William Pinkerton appeared to testify, and a committee of the Knights of Labor, consisting of Messrs. Hayes, Wright and Devlin, was also present and submitted to the investigating committee a series of questions to be put to the witnesses. The Pinkerton brothers presented a written statement, giving a history of their agency and an account of its methods. They upheld the character of their employees for trustworthiness and reliability, denied that it was customary for their men to carry arms or that the men ever wantonly or recklessly fired a shot or used weapons without being sworn in as deputy sheriffs or otherwise properly authorized, and alleged that the men sent to Homestead were to have been deputized and that Colonel Gray was understood to be authorized to deputize them. When the sub-committee charged with the investigation came to sum up and prepare a report, it was found that the members were hopelessly divided, so that the work done, as far as it was likely to affect congressional action, might be considered as wasted. Some of the members, however, did not hesitate to give publicity to their individual views. Mr. Bynum held that if the Carnegie firm could legally bring in 300 Pinkerton guards, it would be equally justified in bringing in 10,000--that is to say, a full-sized army equipped to levy war. He spoke in very severe terms of Sheriff McCleary, describing him as a "poltroon," whose conduct during the riot was simply cowardly.
