There were many more creatures on the farm now, though the increase was not so great as had been expected in earlier years. Many animals had been born to whom the Rebellion was only a dim tradition, passed on by word of mouth, and others had been bought who had never heard mention of such a thing before their arrival.

The farm possessed three horses now besides Clover. They were fine upstanding beasts, willing workers and good comrades, but very stupid. None of them proved able to learn the alphabet beyond the letter B. They accepted everything that they were told about the Rebellion and the principles of Animalism, especially from Clover, for whom they had an almost filial respect; but it was doubtful whether they understood very much of it.
