This collection is made up of letters that B. F. Tarr wrote to Moses Lane, his brother-in-law (6 items, October 29, 1841-February 25, 1848); Edward F. Tarr, his brother (3 items, January 25, 1846-July 11, 1848); and 3 other recipients (February 14, 1847-December 7, 1847) about his life in Chillicothe, Missouri.
Tarr's letters contain some of his observations about local farming practices and the differences between life in New England and in the South. His letter of December 10, 1845, contains a passage on the "spirit of improvement" among Northerners and slow industrial progress in the South. He often shared personal news, such as his intention to establish a legal practice and updates about his family's fragile health. His wife Harriet occasionally contributed to his letters until her death in 1847, and he reflected on his loneliness after his children moved temporarily to Wisconsin (April 16, 1847). Though he focused primarily on personal matters, he mentioned giving a speech after the American victory at Vera Cruz (April 16, 1847).
