On chapter 20 What is Arthur's home filled with?

At the home of the late Arthur Jarvis, James Jarvis finds many letters and invitations asking Arthur to speak. He sees four pictures on the walls: Christ crucified, Abraham Lincoln, the white gabled house of Vergelegen, and a painting of leafless willows by a river. On the bookshelves Jarvis finds hundreds of books about Abraham Lincoln, as well as many books about South Africa and its history.
