John Henry was born a slave. He had to a work of a full grown man. He worked harder than anyone, and he grew very fast soon becoming the strongest man there. The civil war ended and he became free, and decided to look for a job.
John found a job for a rail road worker, even though it was very dangerous.
The boss is threatening to take all the jobs away from the people on the railroad. He needs to get this done soon. Then a guy with a machine appears and says this will work faster than any of your workers. John Henry challenged him and won but his heart could not stand how fast he worked and he died.
I bet my machine is better than any of your workers.
