The pigs did not actually work, but directed and supervised the others. With their superior knowledge it was natural that they should assume the leadership. Boxer and Clover would harness themselves to the cutter or the horse-rake (no bits or reins were needed in these days, of course) and tramp steadily round and round the field with a pig walking behind and calling out “Gee up, comrade!” or “Whoa back, comrade!” as the case might be.

–Animal Farm,
