According to Catherine's diary, how did Hindley treat Heathcliff?

He reads some entries which evoke a time in which Catherine and Heathcliff were playmates living together as brother and sister, and bullied by Joseph (who made them listen to sermons) and her older brother Hindley. Apparently Heathcliff was a 'vagabond' taken in by Catherine's father, raised as one of the family, but when the father died Hindley made him a servant and threatened to throw him out, to Catherine's sorrow.
