I will work harder
Boxer is the main work force of the farm
This type of propaganda is a bandwagon piece because when he says ( I will work harder) It persuades all the other animals to join in and help because boxer is so looked up to because he does the most and without him the wind mill would have never been accomplished.He was so dedicated that he would get up and hour earlier then everybody else to carry a lode of rocks from the quarry to the windmill.
Four legs good two legs bad
When the sheep would blurt this it would cause the other animals to believe them because there is so many of them so the other animals couldn't disagree with them because there was so many of them This type of Propaganda is called repition
