If you pass down Broadway to the main entrance to Trinity Church, and then turn abruptly to your left and cross the street, you will find yourself at the head of Wall street, the great financial centre of America. It is a narrow street, extending from Broadway to East river, and lined with handsome brown stone, marble, and granite buildings. Scarcely a house has less than a score of offices within its walls, and some have very near three times that number.
