This folder contains correspondence, reports, and other documents relating to the operations of Edison illuminating companies. Most of the documents pertain to the business of the Edison Electric Illuminating Co. of New York. Included are several reports by Spencer Trask, president of the New York company, regarding earnings and operating policies; and correspondence concerning the exhibition of a jumbo dynamo from the Pearl Street station at the World's Columbian Exposition in Chicago. There is also a letter from William D. Marks, president of the Edison Electric Light Co. of Philadelphia, commenting on the price of light generated by that company; and a comprehensive statistical report surveying the performance and profitability of approximately thirty-five central stations. Some documents are partially illegible due to water damage and faded ink.

All of the documents have been selected except for 9 routine meeting announcements of the Edison Electric Illuminating Co. of New York.
