This folder contains correspondence and other documents relating to the business of the Edison Portland Cement Co. in the United States and abroad. Included on one of the incoming letters is a comment by Edison in regard to how "ruinous competition" had depreciated the value of the company's stock. Another marginal notation by Edison refers to the annual shutting down of the cement plant from December to March and to his plans to remain closed until "the prices are fair."
Less than 1 percent of the documents have been selected. Not selected are routine items pertaining to equipment and supplies, monthly sales, and financial matters, including stockholders' accounts. Some of the unselected material contains references to the construction of Edison's benzol plant in Johnstown, Pennsylvania, and to firms paying royalties for the use of Edison's crushing technologies.
