How are the Black Hawk girls different from the "country" girls?

Black Hawk girls are not expected or encouraged to choose vocations for themselves, and they are just expected to get married. Their options in life are limited to becoming a wife and a mother. On the other hand, the country girls who are born poor have much more open to him. Since their families do not have the luxury of allowing them to stay at home, they have to go out into the world to work, and they there discover the myriad of possibilities open to them. They are thus able to actually choose a vocation, make money, and more fully engage in worldly pursuits.
