Three thousand men and women--young people just budding into manhood and womanhood, old folks with whitened locks and faltering step--crowded the spacious Central Music Hall and its approaches on the night of June 28, to express their detestation of the crime that had stained the fair fame of the Garden City, to denounce the criminals and to demand of those responsible for the execution of the law that no effort be spared to bring the guilty to justice. It was one of the most cosmopolitan assemblages that had ever been gathered under a roof in Chicago. There were native Americans, British Americans and Irish Americans, Swedes and Italians, Frenchmen and Germans. Members of the colored race were scattered here and there through the vast audience, and even the Chinese colony had its representatives in a couple of distinguished looking Celestials, who, with characteristic modesty, occupied seats away back in the rear. THE PROMINENT CITIZENS PRESENT. Equally striking and significant was the array of citizens that occupied the stage. Back of W. H. Dyrenfurth, President of the Personal Rights League, under the auspices of which the gathering had been called, and who officiated as temporary chairman, sat men of such national and local celebrity as Judge Prendergast, W. P. Rend, Robert Lindblom, of the Board of Trade, Congressmen George G. Adams and Frank Lawler, Alderman John Dalton and Representative Charles G. Dixon, the prominent labor leader. In one of the boxes sat Herman Raster, the noted editor of the _Staats Zeitung_, in another United States Commissioner Phil. A. Hoyne. To the right and left could be seen scores of men of high social and official position, side by side with divines of the Catholic, Protestant, Methodist, Baptist, Presbyterian and other denominations. Few of these could claim any personal acquaintance with the murdered man, many more had known him scarce by name or even looked upon him in the flesh, but one and all were animated by the same motives--those of respect to his memory and a deep-rooted determination that the foul crime should and must be avenged.
