William Roberts, a member of the advisory committee, gave a very clear statement of the causes of dissension at Homestead. The wage reductions, he held, affected not the men who were making exceptionally high wages but many who for eight weeks had not averaged $1 a day. For instance, one man who, under the old scale made $2.23 a day would make under the new one offered by the firm only $1.32, while the heater who made $4.31 suffered no reduction. Mr. Roberts advocated compulsory arbitration. In answer to a question regarding the comparative rates of wages in the Homestead and other mills, he said: "In the American iron works, Carnegie's principal competitor, a roller is paid 70 cents per ton while at Homestead he is paid only 22 or 23 cents. A plate-mill roller at Homestead is paid 14 cents per ton, while at Jones & Loughlin's he is paid 72 cents. The product is similar, it goes into the same market and is used for the same purpose." Colonel James H. Gray, Sheriff McCleary's chief deputy, described the trip of the barges to Homestead, and corroborated the Sheriff's claims that the Pinkertons were not deputized and that orders had not been given to deputize them. He said positively that the Pinkertons did not fire a shot until they had to do so in self-defense. This concluded the second day's session of the committee. When the committee re-convened on the morning of July 14, John A. Potter, general superintendent of the Homestead mills, was the first witness summoned. Mr. Potter furnished data as to the equipment and capacity of the mills, but expressed ignorance as to the cost of producing a ton of steel. He assigned as the reason for reducing wages that the Carnegie firm was "ahead of competitors" and paying more than the owners of similar mills, and therefore thought it should have "some of the advantages." Mr. Potter had been on the Little Bill when the Pinkertons tried to land at Homestead, but had declined to take the responsibility of entering the mill yard by force. The remainder of the morning was occupied principally with the hearing of Homestead workmen who testified as to the effect of Mr. Frick's propositions upon their respective earnings, and of watchmen and others who had been connected with the Pinkerton's expedition and who described their various experiences. Mr. Frick was recalled and permitted to rebut some of the assertions made by the workingmen. To prove that his firm did not control the billet market he cited the fact that Jones & Laughlin's mill has a capacity of 1000 tons daily, while the output at Homestead is 800 tons daily. He again refused to give the labor cost of producing a ton of steel although Congressman Boatner twitted him with refusing to give the information "on which protective legislation is asked for." "I do not think we asked for the legislation," observed Mr. Frick. "You have been greatly misrepresented then," said Mr. Boatner grimly.
