This letterbook covers the period April 1895-January 1898. Most of the correspondence is by Walter S. Mallory, vice-president of the company. The letters deal mainly with insurance renewals, stock transactions, company financial obligations, and plant operations. Some of the items pertain to Mallory's personal affairs. Other letters relate to Edison's efforts to attract outside investors to the company, the assertion of his ore milling patent rights, and a comparison of the company's costs and profits with a similar operation in Michigan. There is also a list of stockholders dated December 31, 1895. A few letters concern the phonograph business. The front cover is marked "N. J. & Penn Conc Wks W. S. Mallory #1." The spine is marked "WSM 1." The book contains 501 numbered pages and an index. Pages 73-74 have been removed from the book. Less than 20 percent of the book has been selected. Some of the letters may be difficult to read due to very faint green ink and purple smeared ink. Related letterbooks can be found in the Walter S. Mallory Papers (Special Collections Series).
