This letterbook covers the period January-March 1897. Most of the correspondence is by Walter S. Mallory, vice-president of the company. The letters deal mainly with personnel matters, building renovations, equipment, and supplies. Included are letters relating to operations at the Ogden works, the use of respirators in dusty areas, and the depressed price of ore. Also included are specifications, sent to prospective contractors, for the bricker furnaces and ovens (one example has been selected). One letter deals with the possibility of making bread from a combination of crushed stone and wheat. Another pertains to the installation of a new telephone at Glenmont. The spine is stamped "Letters." The book contains 497 numbered pages and an index. Approximately 5 percent of the book has been selected. Courtesy of Thomas Edison National Historical Park.
