In the meantime, around police head-quarters, in Mott Street, things wore a serious aspect. From six o'clock in the morning, the various detachments of police kept arriving until Bleecker, Houston, Mulberry, and Mott Streets were dark with the massed battalions, ready to move at a moment's notice. Rations were served out to them standing. Early in the day, Governor Hoffman and staff arrived, and were quartered in the Superintendent's room, while General Shaler and staff were quartered in the fire marshal's office. Commissioners Manierre, Smith, and Barr were in their own rooms, receiving reports from the various precincts over the wires. A little after nine a dispatch came, stating that the quarrymen near Central Park had quitted work, and were gathering in excited groups, swearing that the Orangemen should not parade. Immediately Inspector Jamieson, with two hundred and fifty policemen, was despatched in stages to Forty-seventh Street and Eighth Avenue, to watch the course of events. Another dispatch stated that an attack was threatened on Harper's building, in Franklin Square, and Captain Allaire, of the Seventh Precinct, was hurried off with fifty men to protect it. A little later came the news that the Orangemen had determined to parade at two o'clock, and a police force of five hundred, as we have already stated, were massed in Eighth Avenue, opposite Lamartine Hall. About noon, a body of rioters made an attack on the armory, No. 19 Avenue A, in which were a hundred and thirty-eight stands of arms. Fortunately, the janitor of the building saw them in time to fasten the doors before they reached it, and then ran to the nearest police-station for help, from which a dispatch was sent to head-quarters. Captain Mount, with a hundred policemen, was hurried off to the threatened point. He arrived, before the doors were broken in, and falling on the rioters with clubs, drove them in all directions. During the forenoon, Drill-captain Copeland was given five Companies, and told to seize Hibernia Hall, where arms were being distributed. As he approached, he ordered the mob to disperse, but was answered with taunts and curses, while the women hurled stones at his face. He then gave the order to charge, when the men fell on the crowd with such fury, that they broke and fled in wild confusion. Meanwhile, the detectives had been busy, and secured eighteen of the ring-leaders, whom they marched to police head-quarters.
