Volumes 35-40 cover Thompson's trip back to the United States in 1910. She describes lectures and meetings, and discussions on the outbreak of World War I. Her diary entries become less frequent during her stay in the United States. Volumes 40-57 span Thompson's third trip to Africa (1911-1917), and entries tend to be bit longer and more descriptive. On this trip volumes 44-49 were written in diary volumes entitled "Warriors of Africa," whose covers depict African natives, and volumes 52-55 in volumes bearing the title "Empire Exercise," portraying historical events. Volumes 57 and 58 describe Thompson's travels during 1916-17 (at the height of World War I) to Hong Kong, Japan, Canada, and the U.S. Volumes 59-60 recount her time back in the United States; much of the content revolves around religious and political meetings on World War I, and the 1918 U.S. midterm elections.
