On chapter 18 Jarvis wrestles with questions- if a black has more education, then what will result? And, if the blacks were allowed to farm more land, then what would be the result?

If blacks had more education they would probably move away to the city or find employment with better pay. THey would also know how to farm better which is what Jarvis needs. Jarvis sees blacks as commodities rather than farmers. He thinks they would ruin the land they had.
