ABSTRACT
THUS in the 35 years between the end of the Civil War and the end of the century, American output figures leapt upward, while at the same time control over that output became concentrated to a degree previously unknown. After 1900 the situation changed in that the picturesque figures of the 19th century were largely replaced by the boards of directors of more impersonal corporations—Carnegie by United States Steel, Hill by the Great Northern Railroad, Rockefeller by the Standard Oil Trust; but the concentrations of power in a few hands remained.
