John William Gardiner was born in or near Platte City, Missouri, in 1851. In March 1855, Gardiner and his family moved to the future site of Winchester, Jefferson County, in the newly opened Kansas Territory. During 1875, he taught school and simultaneously took classes in Leavenworth to obtain his teaching certificate. Many of the diary entries describe his teaching, weather, the grasshopper plague, and extracurricular activities such as singing and visiting friends. A transcription prepared by the diary donor, Allen Gardiner, follows the diary images and includes a one page introduction. An uncorrected, searchable OCR file is available as "Text Version" below.
