Also included is a letter to Charles Batchelor (1892) in which Edison discusses bricking technology and the cost of cement. Other letters relate to the license arrangements with Edison and the Edison Ore Milling Co., Ltd., and leases and agreements with Edison and the Philadelphia & Reading Railroad Co. The correspondents include Charles Edison; Charles Batchelor, general manager; Thomas Butler, secretary; Alexander Elliott, Jr., and Sherburne B. Eaton, attorneys; and George W. Perkins, secretary of the Interstate Park Commission.
