This letterbook covers the period May-June 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. Other letters pertain to insurance policies on Edison's life and the Ogden works, the processing capacity expected from the crushers and the furnace, and Edison's perfectionism regarding the design of machinery. The front cover is stamped "Copying Book" and is marked "from May 9th 1894 to June 5th 1894." The spine is labeled "#2 May 9, 1894 to June 5, 1894." The book contains 501 numbered pages and an index.
