Found while fishing for Orwell stuff:
T S Eliot rejected "Animal Farm" for publication.
"We have no conviction that this is the right point of view from which to criticise the political situation at the current time," wrote Eliot, adding that he thought its "view, which I take to be generally Trotskyite, is not convincing".
Eliot wrote: "After all, your pigs are far more intelligent than the other animals, and therefore the best qualified to run the farm--in fact there couldn't have been an Animal Farm at all without them: so that what was needed (someone might argue) was not more communism but more public-spirited pigs."
