Where does the family stay in a grease-spattered one room shack?

What chapter are you referring to?

The Hooper Ranch

Ma opened the door of the house and stepped inside. The floor was splashed with grease. In the one room stood a rusty tin stove and nothing more. The tin stove rested on four bricks and its rusty stovepipe went up through the roof. The room smelled of sweat and grease.
