One of the chief literary devices that is used in this chapter, and indeed gives the chapter its name, is the way in which Rose's mother compares her daughter to a tree that is "without wood." Note what she says to her daughter and the kind of advice that she gives her, and the simile that she uses to give this advice:
She said that I was without wood. Born without wood so that I listened to too many people. She knew this, because once she had been the same way. "A girl is like a young tree," she said. "You must stand tall and listen to your mother."
Note the way in which the simile is used to introduce how girls should behave and also this comparison is one that is continued through the chapter as Rose's mother wants her daughter to act like a tree and to gain the "wood" that her character so clearly lacks at the moment. "Standing tall" as a tree becomes particularly important in Rose's developing character, therefore.
