Chapter 29 shows the narrator reading an ethnological study called the Authoritative History of Junitaki Township. He reads about an indigenous Japanese Ainu man who serves as a guide to Japanese farmers trying to find a remote area in which to settle.

I'm not sure what you are supposed to be arguing against. Chapter 29 serves to show the rise and fall of the town which appears to have borne the spirit of the sheep. The original settlers clearly cared for the land, and the original Ainu guide was primarily responsible for the success of the area. And yet, as with so many other individuals who encounter the sheep, he died a poor, lonely death. The town only faltered after the arrival of the sheep, signifying again the relation between the sheep and the power of authority.
