McCormick did the opposite; he moved West, to Chicago, in 1847.
Chicago was then a town of hardly ten thousand, but McCormick foresaw its future, built a factory there, and manufactured five hundred machines for the harvest of 1848.

From this time he went on from triumph to triumph.

He formulated an elaborate business system.

His machines were to be sold at a fixed price, payable in installments if desired, with a guarantee of satisfaction.

He set up a system of agencies to give instruction or to supply spare parts.
