Final answer:
Without the specific passage from Chapter 17, we cannot accurately discuss what good Buck has to say about the Shepherdsons.
Step-by-step explanation:
In Chapter 17 of the novel, Buck actually has something good to say about the Shepherdsons which is a rare occurrence given the context of the feud that is a central theme of the story. Unfortunately, the provided excerpts do not contain the specific passage required to answer this question accurately. Therefore, the novel itself needs to be consulted to offer a precise and relevant explanation.
Good interpretations of literature often involve a detailed understanding and analysis of the text. Understanding both the positive and negative aspects of characters can offer insight into the complexity of human behavior and the themes of a novel. In this case, observing that Buck expresses something favorable about the Shepherdsons would delve into these complexities.
