The opening up of the Great Plains after the Civil War produced a new wheat and cattle frontier, in the cities there were now millions of people who could not feed themselves, and the railroad revolution made it possible to move food quickly to satisfy urban demand. The result was massive growth in American agriculture – between 1870 and 1900 the number of farms doubled to 5.7 million, wheat production more than doubled to 600 million bushels, and the number of cattle virtually tripled to 68 million.
