The dated entries in this book cover the period January 1893-September 1895, but most of the entries are undated. The book contains records of tests and experiments, reports, and instructions. Reported are weights of materials, tests of tailings, instructions for the storage of sand, and experiments relating to the Hoagland rolls, torque, and sand. The authors are mostly unidentified, but the volume includes a report on rosin by Walter S. Mallory and a report on sand by Francis R. Upton. The book contains 384 numbered pages, many of which are blank. Approximately 15 percent of the volume has been selected. The unselected materials pertain to insurance, notes due, and accounts.

Six loose pages have been inserted into the book. These include undated documents by Edison pertaining to plant capacity and transportation costs. There are also notes by Mallory regarding tests with the Hoagland rolls.
