This letterbook covers the period September-November 1892. Most of the correspondence is by William S. Perry, treasurer of the company; John P. Walsh, sales agent for sand; and Edwin I. Olmsted, clerk. The letters deal mainly with stock transactions, personnel matters, company financial obligations, equipment, supplies, and sand orders. Many of the documents are concerned with production at the Ogden works and the purchase of new bricking equipment. One letter pertains to the wages paid to Thomas A. Edison, Jr. Another relates to changing the name of the location of the mill from Ogden to Edison. The spine is stamped "Letters" and is marked "C 5." The book contains 693 numbered pages and an index. Less than 5 percent of the book has been selected. Courtesy of Thomas Edison National Historical Park.
