Materials in the collection date mainly from the late 1870s and pertain primarily to banking transactions, although some mercantile records are included. The records consist of correspondence (1876-1878) from Breyman & Summerville, French & Gilman, Heppner & Maddock, Ladd & Tilton, Marshall Johnson Kinney, Henry R. Sels, and others, relating to cattle, the wool and hide trade, and banking. Also included are records of shipments to Camp Harney, Camp Logan, and Camp Watson in 1868.
