This building was originally constructed for the Merchants' Exchange, and it afterwards became the Custom House. It is hereafter to be the office of the National City Bank, the largest financial institution of New York. Wall Street goes on to the river, where there is a ferry to Brooklyn. Down William Street is the broad, low, granite building, with a columned portico, of the Farmers' Loan and Trust Company, another financial institution of renown. It is evident, as Broadway is traversed northward between the huge office-letting structures, reared skyward, and among them the little, narrow, crooked streets, pouring their traffic into the main stream, carrying a vast, surging mass of humanity, that the crowded-in New Yorker, deprived of lateral expansion, thus seeks needed relief by mounting upward. Fulton Street here stretches across the island from river to river, the turmoil from its conflicting streams of traffic showing the full tide of restless development in lower Broadway. Above is the white marble Park Bank and the enormous St. Paul Building, rising three hundred and eight feet, twenty-six stories high. Opposite is the sombre church of St. Paul, with a tall spire, the oldest church-building in New York, built in 1756, containing the memorial of General Montgomery, who fell at the storming of Quebec in 1775, and in the graveyard a monument to Emmet, the Irish patriot. Just beyond is the triangular City Hall Park, with Park Row diagonally entering Broadway. Here can be got an idea of the rush and restlessness of New York, for two enormous streams of traffic pour together into lower Broadway, at probably the worst street-crossing in the world.
