This pocket notebook contains only a few dated entries covering the period January-February 1875. The cover of the book is marked "Time on Work Dannod in a/c with Edison & Murray," but only the first two pages deal with Dannod's account. The remainder of the book records hours worked by employees on perforators, clocks, transmitters, relays, fire alarms, and other pieces of telegraph equipment. Approximately 30 pages of this unnumbered book have been used. Courtesy of Thomas Edison National Historical Park.
