This letterbook covers the period August 1896-March 1897. Most of the correspondence is by Walter S. Mallory, vice-president of the company, and Edwin I. Olmsted, purchasing agent. The letters deal mainly with equipment, supplies, and sand orders. Also included are letters by Edison relating to the market potential and production of his briquettes, the attributes of managers at the Ogden works, and the value of the mill for tax purposes. Other items pertain to the financial status of the company. The spine is marked "N.J. & P C W." and "12" and is labeled "Letter Book From Aug. 27, 1896. To Mch. 19, 1897. N.Y. Office." The book contains 999 numbered pages and an index. Approximately 5 percent of the book has been selected. Most of the handwritten letters are in very faint green ink and may be difficult to read.
