Running east from Broadway, just below Wall Street, is Exchange Place. It is a narrow street and a short, but it is not a little street. Huge buildings are its walls, which seem almost to meet overhead. Straight up they tower, face to face, staring at each other with countless eyes. Daily into these few buildings come thousands and thousands of people: old and young, gay and sad, financiers and office boys, — to work. It is a good-sized town in one street. It is a veritable cañon of the city.
