Cyrus McCormick grew up on a farm in Virginia. His dream was to earn a million dollars. In 1833
that was a lot of money. An ordinary worker only earned a nickel(镍币)an hour. Twenty-six years later,
he earned a million dollars. He also changed the way people farmed,with his wheat harvester called the
reaper(收割机). Cyrus was very generous,sharing his money with people who needed help. Before his
invention ,a farmer could harvest only one to three acres (英亩) a day. With the invention, a farmer and
a helper could harvest 12 acres a day!
He had invented the reaper when he was only 22 years old. His father had tried for 15 years to invent a harvester, but had not been able to build one successfully. He had made a lot of mistakes, but young
Cyrus learned from his father's mistakes. He asked his father if he could take over working on the
invention. His father gave his permission, but thought it was hopeless (没有希望的) .In just 2 months he
was able to make a harvester. When he tested it,he could harvest an acre an hour.
