The inside of this cover holds a letter from Victor Cragin Noyes (1847–1905) to his father John Humphrey Noyes, dated October 10, 1865, in which he describes his work on indexing the manuscripts. Victor Noyes describes some of the drawings he isolated from the manuscripts; the line is followed by a note: "These pictures are retained at O.C. [Oneida Community] J.H.N."
