This collection consists primarily of letters from Henry Pichoir, North Bloomfield's secretary, and Lester L. Robinson, its president, to William H. Radford and J. G. Mather, superintendents of company operations in the field, between January 3, 1890, and January 7, 1891. The letters deal mainly with the state of accounts kept by the superintendents, the physical condition of the company's ditches and flumes after storms, and the company's efforts to control the run-off from its operations. There are also occasional discussions of the company's relationship with other mining firms, including water leases and operating facilities. Persons represented by 5 letters or more: Joseph H. Mooser (14 letters); Henry Pichoir (68 letters); and Lester Ludyah Robinson (5 letters). Notable items include two letters from Lester Robinson to Superintendent Mather, April 9, 1890 (HM 51127) and June 23, 1890 (HM 51128), which discuss plans for water sampling and the construction of tunnels for water diversion to guard against run-off.
