This letterbook covers the period November 1893-January 1894. Most of the correspondence is by Edison and Walter S. Mallory, vice-president of the company. The letters deal mainly with personnel matters, company financial obligations, equipment, and supplies. Some of the items pertain to insurance for the Ogden works, the replacement of its chief engineer, and the lease of property in Michigan and the possible erection of a mill there. There are also letters containing Edison's views on lamp prices in Europe and on problems at the Edison Phonograph Works. A loose page inserted at the end of the book contains a note in Edison's hand, dated August 22, 1895, announcing that "work is hereby suspended at these Works." The spine is stamped "Letters." The label on the spine and the flyleaf are inscribed "4." The inside front cover contains the inscription: "Letter book #3 sent to Mr. Mallory at Ogden by Express April 23/94 J F Randolph." The book contains 698 numbered pages and an index. Less than 10 percent of the book has been selected.
