With the repulse of the attempt to set fire to the Duquesne depot ended all active efforts by the mob to destroy property, and after that Sunday night no mob of any size was again assembled, although it was several days before complete order was fully restored, as the people had lost confidence in all the laboring men, and no one knew who to trust or what to expect from others on account of the extent to which the demoralization had gone. About sixteen hundred cars, (mostly freight,) including passenger and baggage cars, with such of their contents as were not carried away by the thieves; one hundred and twenty-six locomotives, and all the shops' materials and buildings, except one or two small ones, of the railroad company, from above Twenty-eighth street to the Union depot, were burned on that Saturday night and Sunday. It has been estimated, by a competent person, that the damage, including loss of property and loss of business, consequent upon the interruption of business, which was inflicted by the mob, at Pittsburgh alone, was $5,000,000. This may be a large estimate, but if the consequential damages could be correctly arrived at, the total damage would fall but little short of the figures given. The actual loss of property by the railroad company alone, not including the freight they were transporting, is estimated at two million dollars, by the officers of the company, from actual figures made. The authorities of Allegheny county adopted thorough measures to ascertain the extent of the loss of property, and to that end appointed a committee to investigate claims of those claiming damage. One hundred and sixty-nine claims were settled by the committee, that is, the amount of each claim of this number was adjusted and agreed upon by the committee and the parties, and the total amount thus adjusted is about one hundred and sixty thousand dollars, and all this is strictly private property. Some persons refused to adjust the amount of their claims with the committee, among which is the claim of the elevator company, amounting to the sum of two hundred thousand dollars. Property that was stolen was also recovered and returned to the railroad company, amounting in value to at least sixty thousand dollars. The tracks from Union depot out to and beyond Twenty-eighth street were nearly all ruined by the fire, the rails being warped and twisted and the ties burned; they were also covered with the debris of the burned cars, and it was about a week after the destruction, or until July 30th, before the railroad company were enabled to get their trains all running regularly again over this portion of the track. During the troubles of the 20th and 21st, efforts were made by the strikers to come to an understanding or compromise with the railroad officials, and a committee to confer with the officials was appointed.
