What happened to the missing milk? The apples? What was Squealer's explanation?

The mystery of the missing milk is solved when the pigs declare that only they can use all apples and milk on the farm. The other animals grumble, but Squealer explains that the pigs are crucial to the running of the farm and need the milk and apples to stay healthy. If the pigs fail, Squealer says, Mr. Jones will return. The animals agree that the pigs should get the milk and apples.
