Setting

England, on a farm. The setting fits the book, as you might expect. As far as time goes, the political implications of the 1940's are weighty, and in fact the central core on which the story's parable focuses. Orwell was writing about sort of recent events (earlier in the century) in Russia. What events, you say? The Russian Revolution. That's how these parable deals work.
