There are all sorts of changes that take place in this chapter.
The most important change is that Snowball gets expelled from the farm because he has been disagreeing with Napoleon too much.
There are little changes going on as well. For example:
- The skull of Old Major has been dug up and the animals pay reverence to it every Sunday.
- The animals no longer all sit together at the meeting. Instead, Napoleon, Squealer and Minimus sit up front on a platform with the dogs protecting them.
- Another thing is that we find out that now Napoleon is saying he had been in favor of the windmill all along.
