This letterbook covers the period May-June 1897. Most of the correspondence is by Walter S. Mallory, vice-president of the company. The letters relate mainly to personnel matters, building renovations, insurance, equipment, and supplies. Included are letters sent to prospective contractors regarding the company's decision to have bricking machines made in four different shops (an example has been selected). Some letters deal with work done for the New Jersey Zinc Co. The spine is stamped "Letters" and is labeled "May 21, 189[7] to June 23." The book contains 498 numbered pages and an index. Less than 5 percent of the book has been selected.
