It begins at the Bowling Green. From this point it extends in a straight line to Fourteenth street and Union Square. Below Wall street it is mainly devoted to the "Express" business, the headquarters and branch offices of nearly all the lines in the country centring here. Opposite Wall street, and on the west side of Broadway, is Trinity Church and its graveyard. From Wall street to Ann street, Insurance Companies, Real Estate Agents, Banks, Bankers and Brokers predominate. At the southeast corner of Ann street is the magnificent _Herald_ office, and adjoining it the Park Bank. Both buildings are of white marble, and the latter is one of the grandest in the Union. Immediately opposite are St. Paul's Church and graveyard, just above which is the massive granite front of the Astor House, occupying an entire block, from Vesey to Barclay streets. On the right hand side of the street, at the lower end of the Park, is the unfinished structure of the new Post Office, which will be one of the principal ornaments of the city. In the rear of this are the Park, and the City Hall. Back of the City Hall, and fronting on Chambers street, is the new County Court-House, which proved such a gold mine to the "Ring." Across the Park you may see Park Row and Printing-House Square, in which are located the offices of nearly all the great "dailies," and of many of the weekly papers. Old Tammany Hall once stood on this square at the corner of Frankfort street, but its site is now occupied by the offices of _The Sun_ and _Brick Pomeroy's Democrat--Arcades ambo_. [Picture: A. T. STEWART'S WHOLESALE STORE.] Beyond the City Hall, at the northeast corner of Chambers street and Broadway, is "Stewart's marble dry goods palace," as it is called. This is the _wholesale_ department of the great house of A. T. Stewart & Co., and extends from Chambers to Reade street. The _retail_ department of this firm is nearly two miles higher up town. Passing along, one sees in glancing up and down the cross streets, long rows of marble, iron, and brown stone warehouses, stretching away for many blocks on either hand, and affording proof positive of the vastness and success of the business transacted in this locality. To the right we catch a distant view of the squalor and misery of the Five Points. On the right hand side of the street, between Leonard street and Catharine lane, is the imposing edifice of the New York Life Insurance Company, one of the noblest buildings ever erected by private enterprise. It is constructed of white marble.
