This letterbook covers the period July 1901-June 1902. Most of the correspondence is by Walter S. Mallory, vice-president of the company, and Orville Benson, manager of the Edison mill. The letters deal mainly with the disposition of equipment and supplies, the reduction of the work force at the Ogden works, and efforts to reduce tax assessments against the company. Some of the items pertain to work done for the New Jersey Zinc Co. in Franklin, New Jersey. There is also correspondence about the development of ore milling interests in England and Norway. A few of the items relate to the Edison Portland Cement plant at Stewartsville, New Jersey, and the closing of the mill at Edison. Three letters deal with Edison's library at Edison, New Jersey, and with a photo of Edison at the mill sought by Mina Miller Edison. A portion of company letterhead is affixed to the front cover and is inscribed "From July 26, 1901. To June 14, 1902." The spine is stamped "Letters." The book contains 998 numbered pages and an index. Approximately 10 percent of the book has been selected.
