A numerous array of witnesses was brought forward by the prosecution. Attorney L. K. Porter conducted most of the cross-examinations for the defense.
Dr. Weible, surgeon for the Carnegie Company, submitted a tabulated report of the cases treated by him in the mill.
Louis Wolfe repeated the testimony which he gave at the Beatty hearing.
George W. Amy, Henry P. Thompson and Louis H. Craig, all of Chicora, Butler County, deposed to having worked in the Homestead mill and being stricken with disease, from which none of them had fully recovered. Dr. J. L. Campbell, of Chicora, had treated these men and described their symptoms, which, he said, he had ascribed to mineral poisoning. He was certain that antimony had been given.
Stephen Loveless, of Butler, William H. Johnston, a watchman in the mill; Benjamin Weaver, a steelworker residing at Homestead, and Wilmot Herr, a watchman, deposed to having been attacked by the prevailing malady.
Dr. McGeary, of Homestead, had treated William H. Johnston and was convinced that his patient suffered from arsenical poisoning. In his opinion, impure water, spoiled meat or climatic conditions could not have caused the sickness which occurred in the mill.
Charles H. Smith, an engineer in the Carnegie works, said that he had fallen ill twice and lost 55 pounds. Three doctors were unable to restore his health fully.
William E. Griffith, the man named in the indictment as the victim of the poisoning plot, said that he had been serving in restaurant No. 6 as head waiter. On September 11 or 12, after eating supper in the restaurant, he was seized with diarrhœa and vomiting and was then laid up for a week. On October 6, after drinking some coffee, witness took sick again. This time he was prostrated for eight weeks. Dr. A. P. Vogleman, of Homestead, had treated Griffith and thought that the patient might have been made ill by drinking bad water.
Dr. McGeary (recalled) and Dr. E. W. Dean testified to the conditions attending the case of J. W. Van Winkle, who had died at the Homeopathic Hospital. They thought it safe to pronounce his death due to arsenical poisoning.
Numerous other witnesses gave testimony similar to the foregoing, nearly a week being occupied in listening to the stories of those who had been poisoned and to the diagnoses learnedly set forth by medical men.
