Nestled between the remnants of old Fort Dearborn and the bustling Board of Trade lies a fascinating, yet restricted, territory shaped by decades of commerce. Over the past fifty years, the relentless flow of business has carved deep, rugged canyons through this area, transforming it into a network of vital streets—each a conduit for the vibrant energy of urban life. Towering cliffs of brick, limestone, and granite rise higher each year, shaped by the constant erosion from the ceaseless movement of carts, carriages, omnibuses, cabs, and the throng of shoppers, clerks, and capitalists. Join us as we explore this dynamic landscape and the stories it holds. Summary by HENRY B. FULLER
