 In 1922, Macdonald became a part-time lecturer at the law school. When he left the attorney-general's office in 1924, he became a full-time professor. Macdonald was a popular and effective teacher. One former student describes him sitting at his desk on the rostrum speaking slowly and deliberately while gazing intently at the ceiling. "The more students disagreed (with one another in class) the more Angus encouraged it."
