The collection includes Pitezel’s correspondence mostly to family and friends (with notes and related materials), journals, and writings (essays and a poem), many of which later became books.
Most of his letters are to his mother, brother, Joshua, and sisters, Caroline and Mary. They detail his religious activities, beliefs, the people and situations in which he traveled, preached, and lived, family news, the weather, and illnesses. He was strongly anti-Catholic and reported often on Catholic missionaries and their missionary efforts. The letters are pasted together with related documents, which makes organizing them a challenge.
His journals span September 1846 through September 1851 and detail his life and work in Adrian, Marshall, Sault Ste. Marie, and at Kewanenon Mission, Michigan, and note his visits to Indian chiefs, councils, and medicine men, as well as stories told to him by Indians.
The writings include six autobiographical and religious essays.
Item-level index cards are included at the end of the collection to assist researchers.
