This undated notebook was probably used during January-March 1902. Most of it was used by John V. Miller and unidentified authors, but there are some notations by Edison, including instructions relating to the production of a recording device. The entries consist primarily of notes and lists pertaining to mining surveys, supplies, equipment, and field work assignments. Near the beginning of the book is a draft letter of agreement for the employment of dipping-needle operators. The pages are unnumbered, and the book has been used in both directions. Approximately 25 pages have been used.
