Chicago, Aug. 31.- Gatling guns in nse directly in front of the Auditorium was the scène imminent for a short ime Wednesday. Coupling pins and clubs were the worst weapons actually ronght into use, ho-wever, and the most prominent public ground in the city, the landing place of the world's air steamers, was narrowly spared a pectacle of carnage paralleling the memorable Haymarket riot. During the morning crowds of unem ployed and idle spectators crowded jound the Columbus monument on the ake front. As the crowd grew in numers indications of rioting began to manifest themselves, and in addition to He number of officers in plain clothes circulating among the throng, Chief of Pólice Brennan summoned first 500 uniiormed men and later 1,000. Prior to this the only patrolmen in uniform visible were on the street ends abutting Lake Front park. Meanwhile the throng had greatly multiplied, imjromptu speeches being made at several joints, attracting additions to the crowd. ooon tñe outskirts oí tne great jathering were surging aeross Michigan Doulevard and blocking access to the Auditorium. Along the boulevard and streets leadng from that thoroughfare, trafEc was suspended and a nurober of teams were caught in the mass of people, from which egrsss, owing to the crush, was ïmpossible. The first uniformed pólice to arrive were under command of Inspector Laughlin. They were cheered as they appeared amone the crowd. The inspector was tola that a crowd of 500 Italians had started up State street, bent on mischief. With 30 men the inspector started after the mob. "The pólice carne on the crowd at Louis Spizzari's provisión store at 665 State street. In the basement of Spizzari's market were stored 50 rifles and a number of flags used by the Italian societies in their parades. These the mob demanded and invaded the premises to obtain possession of them. Spizzari. who is a leader among the Italians, addressed the crowd and, after refusing absolutely to let them have the guns or flags, pushed the invaders out of his Rtorfl and locked the doors. As a concession, Spizzari gave the leaders 52 and they bought Italian and American flags and returned to the Columbu8 monument on the lake front, followed by the pólice squad. During the parley the pólice kept the streets near Spizzari's place clear, but made no arrest. News of the events on State street irritated the Lake Front mob, and it becatne more and more disorderly. Excited individuals made speeches continuously and soon stoues began to be thrown. Rioters who were in the eastern outskirts of the mob picked up coupling pins from the Illinois Central tracks and the heavy missiles were thrown toward the pólice. Inspectors Shea and Laughlin at this juncture promptly ordered a charge upon the crowd. The pólice in force were by this time but a short distance eouth of the body of the mob, and before the rioters saw the adyance the shock carne. The contact was of short duration. As the heart of the mob around the monument saw their friendsscatter before the swinging clubs, the leaders turned and fied. Their course lay north and west out of the park to Michigan avenue. In an almost incredibly short time the mob dwindled away as rioters Bonght safe escape in the alleys and streets. During the riot the back door of Batterp D armory. facing the Illinois Central tracks and almost within plain view of the inob, stood wide open. The battery has four 12-pound Napoleons and fmr Gatling guns, all of which the nffiiiT in charge save were ready for business.
