This letterbook covers the period October-December 1894. Most of the correspondence is by Edison and Walter S. Mallory, vice-president of the company. The letters deal mainly with company finances, personnel matters, equipment, supplies, and sand orders. Some of the letters pertain to delays in reopening the Ogden works, attempts to find rubber suits for the miners to wear in wet weather, and the observance of Thanksgiving. A few items relate to the use of magnetic sand to increase the traction of streetcars. One letter contains comments by Edison on his ancestry. The spine is labeled "#6 Oct. 17, 1894 to Dec. 1894." The book contains 500 numbered pages and an index. Approximately 10 percent of the book has been selected.
