Diary belonging to Charles Waterman (1828–1912), written at Fort Riley, Kansas, where his son, John Charles Waterman (1857–1939), was stationed. The journal entry, titled "Introductory to Early Reminiscences," is more reflective than a traditional daily diary, recounting events and memories from his life.

Waterman begins by describing life in Michigan during the 1850s through the early 20th century. Notably, recalls a time in the 1850s when an African American man who had escaped slavery came to his house seeking shelter (page 28). He then discusses the election of Abraham Lincoln (page 47), expresses his belief that slavery was the primary cause of the Civil War, and reflects on the war's impact on his daily life.
