During Saturday night and Sunday morning the mob seemed to have taken possession of the city. They broke open several armories and gun stores, and supplied themselves with arms and ammunition. The banks were threatened, and the city seemed about to be pillaged, the business part of the city being filled with bands of rioters who uttered threats of violence and murder. On Sunday morning the roundhouse and all the locomotives which it contained were destroyed by fire. The Union Depot, the grain elevator, the Adams Express building, and the Pan Handle depot were also set on fire and consumed. The firemen who hastened to the scene and attempted to extinguish the flames were met by armed men and driven back. At half past twelve on Sunday morning a committee appointed by a citizens' meeting tried to open a consultation with the mob, but were promptly driven away. The committee found that they were not dealing with dissatisfied railroad employees but with a mob of the worst of the city's population, there being neither organization nor leader, but each man or party of men doing what the frenzy of the moment suggested. When it seemed as if the whole city was to be destroyed, some of the original strikers were persuaded to attend a meeting of the citizens at four o'clock and arrange to aid in suppressing the incendiarism, and they did this with such a good spirit as showed that the railroad strikers were not a part of the mob and did not countenance its violence. At this meeting the mayor was authorized to enroll five hundred police, but the accounts of the day show that the ranks filled up slowly. The state of terror continued through all of Sunday night, and on Monday morning the mob was still in an unorganized control. Throughout the thirty-six hours from Saturday night until Monday morning a most unusual state of public mind developed here and there which seemed like a moral epidemic. There was almost a wholesale appropriation of goods from the burning cars by men and even women who would at other times have shuddered at the idea of robbery; and after the riot was suppressed goods were for some time voluntarily returned by persons who had taken them unreflectingly, having at length recovered their moral perceptions, which had seemingly been clouded by the vicious influence of the mob. On Monday morning, however, the uprooted law seemed to be recovering a portion of its dissipated majesty. During the night posters had been placed conspicuously throughout the city, on which was printed the law under which the citizens of Allegheny County were liable for all the damage done by the mob or arising from its actions. At eleven o'clock in the morning, a meeting of citizens was called at the Chamber of Commerce, to form a Committee of Public Safety to take charge of the situation, as the city authorities, the sheriff, and the military seemed powerless to control it. This committee presented the following address to the public:
