This folder contains correspondence and other documents relating primarily to land surveys and construction activities at the Stewartsville works. Among the correspondents are Edison, Walter S. Mallory, and Emil Herter. Included are several undated letters in Edison's hand. One concerns a mechanism to absorb shock from the three-high rolls; others pertain to land surveys, property rights, and tenants, as well as the company's investors from Philadelphia (presumably Theron I. Crane and William S. Pilling). Additional documents deal with the costs and construction of the Stewartsville works. Some items indicate payroll expenses at the company's offices in Stewartsville, West Orange, and Philadelphia.

Less than 5 percent of the documents have been selected. The unselected material includes correspondence relating to insurance, equipment, and supplies; a drawing entitled "Plan showing location of tests of Temp. in Mill No.1 March 18, 1900"; and an undated report on operating costs at the New Jersey and Pennsylvania Concentrating Works.
