Manuscripts

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.

Visual Materials

This collection contains 269 stereographs by photographer Carleton E. Watkins, dating from the 1860s to about the 1880s, that chiefly depict buildings, points of interest, and locales in Northern and Southern California. The collection includes 1 stereograph from the Central Pacific Railroad series; 5 stereographs from Watkins' Pacific Railroad Series; 110 stereographs from Watkins' Pacific Coast series; and 150 stereographs from Watkins' New Series. The Watkins' Pacific Coast Series, created between 1861 and 1874, primarily depict locales in Northern California with many images of buildings in San Francisco, views of Yosemite and Mariposa County, Missions, and some mining operations including photographs of the North Bloomfield Gravel Mining Company in Nevada County, California. The Watkins' New Series stereographs, created between 1874 and 1890, consist of images of both Southern California and Northern California, in cities including San Francisco, Pasadena, San Marino, Sierra Madre, and San Gabriel. Among the Southern California residences and properties depicted include the Sunny Slope Ranch of L.J. Rose in San Gabriel, Willow Dale owned by N.C. Carter, and Lake Vineyard owned by B.D. Wilson. Some of the stereographs in Watkins' Pacific Coast Series include titles in the margins in Watkins' own hand (see Nos. 1033, 1135, 1146, 1153, and 1721).
