Among the many meetings attended by the striking garment workers last night, the one held in the park of the Pilsen Brewing Co., was the largest. Several Czech speakers admonished the workers to discard promises and threats alike and to continue in the strike. Mr. Samuel Landers, national organizer of the United Garment Workers, and Miss Margaret Daly, local organizer delivered addresses in English. Mr. Fitzpatrick, president of the Chicago Federation of Labor, announced picket lines will be reestablished today.
