Quotations
Tired as he felt at night, and dark and bitter cold as it was in the morning, Jurgis generally chose to walk; at the hours other workmen were traveling, the streetcar monopoly saw fit to put on so few cars that there would be men hanging to every foot of the backs of them and often crouching upon the snow-covered roof.
