The Carnegie Steel Company formed the nucleus of 
the United States Steel Corporation, incorporated in 1901. 
The center illustration of this circular gives a panoramic 
view of the Homestead Steel Works, at Munhall, just 
outside the city limits of Pittsburgh. Other very large 
plants are the Edgar Thomson Steel Works, at Braddock, 
and the Duquesne Steel Works, at Duquesne. It is the 
opinion of experts that 659%, of the iron and steel tonnage 
of the United States is produced in the metropolitan area of 
Pittsburgh. In the year 1918, the United States Steel 
Corporation shipped 13,849,483 tons of finished steel, 
employed 268,710 persons, and paid out $452,663,524 in 
wages. Pittsburgh plants are estimated to have made an 
increase of fully one-third of their capacity during the war, 
and at present have over 1009, of pre-war productive 
capacity. At the present time it is estimated that the 
Carnegie mills are operating at about 909, of their capacity, 
and independent producers are averaging about the same. 
The United States Steel Corporation has an authorized 
capital of $550,000,000 in common stock, of which $508,- 
302,500 is outstanding, and $400,000,000 in 79, preferred 
stock, of which $360,281,100 is outstanding. 
It is impossible to enumerate all the corporations and 
companies engaged in the iron and steel business, or say 
how much capital is employed therein, but some of the 
other large concerns in the Pittsburgh district are the 
following: 
The Jones & Laughlin Steel Company has a capital
