Major tells the farm about all animals being equal
"'Weak or strong, clever or simple, we are all brothers. No animal must ever kill any other animal. All animals are equal'" (11).
The animals kick out Mr. Jones
"A minute later [they] were in full flight down the cart-track that led to the main road, with the animals pursuing them in triumph" (20).
Snowball is chased out of the farm
"One of them all but closed his jaws on Snowball's tail, but Snowball whisked it free just in time. Then he put on an extra spurt and, with a few inches to spare, slipped through a hole in the hedge and was seen no more" (53).
