Albus was annoyed. Augusta had indeed a history mastery, but he never hired her, because he didn’t want to let Binns go, in order to keep the students dumbed down. It was hard to deny Augusta the position and it was harder to keep Binns in Hogwarts. Augusta blamed him that she didn’t use her history mastery to teach the students in history properly. But the woman still did a lot of damage with Bathilda Bagshot, because she wrote the history books for the students and she explained parts that he didn’t want to be covered. Albus tried to ban the books, but he wasn’t able to find reasons for the banning of the books and much to his annoyance, they were kept in the library. To make matters worse Augusta’s books were course books for the school and he couldn’t stop the books to be used as class material.
