Doing Jim's "holiday" with the hired girls, what do the girls reveal about their families and their lives in America?

The girls discuss how it is difficult for older adults to make the transition to a new country and how difficult it is to be the oldest child when more babies keep arriving. They play a game called "Pussy Wants a Corner," and then Jim tells them about how Coronado the Spanish explorer came as far West as Black Hawk. As they sit in silence, the clouds disappear, and all of a sudden, they see a distant black figure on the horizon. Jumping up to see what it is, they realize that someone had left a plow standing in the field, and it looks molten red and glowing against the backdrop of the sun. The image only lasts for a moment as the sun continues to set.
