"We were taking our morning stroll along the streets," began Patsy, "when on turning a corner we came upon a crowd of people who seemed to be greatly excited. Most of them were workmen in flannel shirts, their sleeves rolled up, their hands grimy with toil. These stood before a brick building that seemed like a factory, while from its doors other crowds of workmen and some shopgirls were rushing into the street and several policemen were shaking their clubs and running here and there in a sort of panic. At first Beth and I stopped and hesitated to go on, but as the sidewalk seemed open and fairly free I pulled Beth along, thinking we might discover what the row was about. Just as we got opposite the building a big workman rushed at us and shouted: 'Go back--go back! The wall is falling.'
