The middle colonies did not have very much lumber. What trees they did have they quickly cut down and converted into boats.
The soil in the middle colonies were rich and fertile this made it good for the farming. They also had some cattle on their farms. They soon made mills to grind the wheat into flour. They grew so much wheat that they were called the breadbasket colony.
Though there were many resources to be found, that was not all the middle colonies had! There were so many people all with jobs, there were shoemakers, newspaper printers, and many more people. If you were to take a walk you would run into all of these people!
