This letterbook covers the period September 1895-January 1897. Most of the correspondence is by Edison and Walter S. Mallory, vice-president of the company. The letters deal mainly with personnel matters, building renovations, equipment, and supplies. Some of the items relate to the quality and marketing of the briquettes (several examples of letters sent to prospective buyers of the briquettes have been selected). Other letters concern the company's financial condition and the design of its stock certificate. One letter discusses the financial status of the Edison Ore Milling Co., Ltd. The book contains 699 numbered pages and an index. Approximately 10 percent of the book has been selected. Many of the letters near the end of the book are written in very faint green ink and may be difficult to read.
