On August 3, Vice-President Morton appointed a committee of senators, composed of Messrs. Gallinger, Pfeffer, Hansbrough, Felton, Sanders, White and Hill to investigate the Pinkerton corporation. Action by this body was deferred until after the Presidential election, the chairman being a stalwart Republican and averse to the opening of proceedings which might furnish campaign material to the Democrats. It was not long until the backbone of the sympathy strikes declared at the Carnegie mills at Lawrenceville, Duquesne and Beaver Falls showed signs of weakening. At Lawrenceville, the company took precautions similar to those taken at Homestead. An eight-foot board fence was built round the mill yard and no person was admitted without a pass from the superintendent. The strikers placed pickets on guard, but, despite their vigilance, several hundred non-union men were spirited in and on August 1, the plate mill was started. One hundred and fifty uniformed policemen and the entire force of city detectives were detailed, at the request of the firm, to protect the mill property at this time. After one day's service the majority of the officers were withdrawn, but enough were left on duty to guard all entrances and approaches to the mill. For the accommodation of the non-unionists, who dared not venture out, cots were set up in the carpenter shop, a rough-and-ready cuisine was improvised, and beer was brought in from the neighboring breweries. The force of "scab" employees increased rapidly, and in a short time, the watchers without began to lose heart and relax their vigilance. Nevertheless the Lawrenceville strike was prolonged for a year, or twice as long as the strike at Homestead, although the Lawrenceville men had signed a contract with the Carnegie Company and had no grievance of their own. When the strike was ultimately declared off, few of the men who went out were employed again by the firm and many of them found themselves reduced to poverty. The Duquesne strike was of short duration. The men had been hastily organized and the new-born spirit of unionism among them was not strong enough to inspire and maintain mutual confidence. A report that non-union men had been secured and that the mill would be started on August 4 caused a stampede, several hundred of the strikers discarding their allegiance to the Amalgamated Association and rushing pell-mell to the mill when it opened up, fearing that their jobs were slipping away from them, perhaps forever.
