Jimmy is going to look for a river while it is frozen, so they can start logging right when the river unfreezes.
In Wyoming, Minnesota it is cold but also perfect for logging. With plenty of trees and a nice flowing river this is the perfect spot.
No mater the weather right when the river unfreezes Jimmy goes to work. He gets tired right away because it's only him using a axe built steel. So Jimmy decides to find better ways to make the process faster.
Once they sped up the process they were cutting trees faster than the river could run. How did they speed up the process? They used faster steam powered saws with circular blade.
Soon they sped the process more by not using rivers instead railroads. They put the logs on there and then take them to the shop to make 2x6.
Once there brought to the factory they make 2x6 wooden planks that people buy to make houses. Also they make the planks that are under the rail road.
