which has distinctly characterized the post-war period.
The stupendous industrial effort put forth during the
World War taught the great value of cooperation, coordination,
 and mass effort. The enlightened constructive
policy which was finally adopted after the breakdown in
1920-1921, and its two-year wake of depression—a program
 which conceded an indeterminate advance in wages,
provided productivity was increased and costs reduced—
has practically produced an American industrial revolution
of epoch-marking significance. Its results have attracted
world-wide comment and study. The leading industrial

to study the secrets of American accomplishment. Undoubtedly
 the policies which were inaugurated here in
1923 will in time revolutionize industrial methods and
performance throughout the world.
