In some of the historical matters such as are brought out in Patriarchs and Prophets and in Acts of the Apostles, and in The Great Controversy, the main outlines were made very clear and plain to her, and when she came to write up these topics, she was left to study the Bible and history to get dates and geographical relations and to perfect her description of details.
