In 1887 a severe banking crisis occurred in Sardinia.
Its trade also in books, hops, horses, and cloth is considerable, and a large banking and exchange business is done here.
The banking institutions are supervised by an inspector of finance, who reports annually to the General Assembly.
After graduating from the university of Pittsburgh he entered the banking house of Thomas Mellon & Sons and later became a partner.
The chief banking offices are also in the square.
