The industrial revolution spread to many parts of the world, including Europe and North America. Many inentions and ideas
that were developed in Britain were taken to North America by immigrants who settled in the new land. These ideas spurred
the development of American Industry. Industrialization spread, first to the lowlands and the northeastern United
States, then eastward and southward across Europe and westward across North America.
Knowledge of new innovation was spread by several means. Workers who were trained in the technique might move to another
employer or might be poached. A common method was for someone to make a study tour, gathering information where he could.
During the whole of the Industrial Revolution and for the century before, all European countries and America engaged in study-touring;
some nations, like Sweden and France, even trained civil servants or technicians to undertake it as a matter of state
policy. In other countries, notably Britain and America, this practice was carried out by individual manufacturers anxious
to improve their own methods. Study tours were common then, as now, as was the keeping of travel diaries. Records made by
industrialists and technicians of the period are an incomparable source of information about their methods.
