Records, 1861-1911, of a lumber company headquartered at Eau Claire, Wis., which owned thousands of acres of timber in Wisconsin's Chippewa River Valley and operated its own farms, flour mills, tow boats, and general stores in the area. The records consist of letterpress books, seventeen of which contain company correspondence and two of General Manager Eugene Shaw's personal correspondence. Also included are miscellaneous loose records consisting of timber "scale" books (Winters 1866-1867); field books delineating timber stands on sections of land (1899, n.d.); and miscellaneous correspondence, business receipts, and legal documents (1861-1911). The microfilmed portion of this collection includes a daybook recording sales in a company store in 1881 and the record of the Eau Claire dynamo and the production of city electric lights, 1893-1894.
