This pocket notebook covers the period December 1898-January 1900. The entries in the first part of the book are by Edison and Emil Herter, chief draftsman at the ore milling plant in Ogden, New Jersey. The remaining entries [not selected] are all by Herter. The Edison material consists primarily of notes regarding the operation and performance of conveyors, rock crushers, rollers, hoppers, pulleys, and belts at the Ogden plant. These notes contain many suggestions and proposals for improvements to the machinery. The entries by Herter are mainly notes, drawings, and measurements pertaining to the construction of buildings and installation of machinery. Included is material relating to conveyors, elevators, and rolls. The activity recorded in these books corresponds with some of the subjects discussed by Herter in Thomas A. Edison v. Allis Chalmers et al.
