The summers he spent here from about ages 6-13 were highly influential on his writing and his development as a person. It is here that he was exposed to the African American slave life, which affected him deeply. A slave, "Unc'l Daniel," had the most impact, serving as an inspiration for the character Jim in the "Adventures of Huckleberry Finn", and shaping his view of African Americans. He states: “It was on the farm that I got my strong liking for his race and my appreciation of certain of its fine qualities.” This farm was the model for the farm used in "Huck Finn". In the town of Florida, he would also draw inspiration from people he met, developing them into characters such as General and Injun Joe. Chapter 14 appeared in the March 15, 1907 issue of the "North American Review". This chapter begins with an excerpt from Susy's biography of him in which she talks about how her sister Clara was always opposite from her. Clara always seemed to be braver than she was as she would stand perfectly still when having a sliver of wood removed from her finger while Susy would be very cowardly. Twain remarks on how Susy had a knack for remembering things very accurately. He then goes on to exclaim his pride in Clara's saying that she was brave, but nobody was braver than God. He was proud that Clara was becoming a great thinker and observer. Twain then moves into a long story about how his family once moved to Berlin, Germany, where he was invited to a dinner with Emperor Wilhelm II. Before going to the party, Twain became friends with one of the officials at the Foreign Office who he would call Smith. Smith was tired of having to work all the time and was considering resigning without getting a vacation. In the end during the party, Smith got his vacation and Twain was honored by the Kaiser, who praised "Old Times on the Mississippi". Twain then explains that he had broken the unspoken law in Germany that if someone entered a house after ten, they must pay a toll to the doorman for waking him. In the later entries Twain would reflect back on the imperial dinner with the Kaiser. Chapter 15 appeared in the April 5, 1907 issue of the "North American Review." This chapter begins with Twain describing his experience renting kittens for the summer time. He relates the three kittens he had at the time to the people around him. Twain claims that conformity is inevitable within most living creatures, especially in man: “They are afraid to be outside; whatever the fashion happens to be, they conform to it.”
