The collection contains agricultural, mathematical, and personal notes; religious meditations; correspondence; and a few legal and business papers. There are also some papers of one of Power's sons, Holloway Bunyan Power, born in 1834 in Alabama. He also was a farmer, and upon his father's death on November 6, 1866, he succeeded him as a preacher for Bethany Baptist Church. Some of the records of the church are included with this collection.
