There is within these papers a Klamath Indian Allotment Census for the Klamath Tribes and a register of persons living in the Yainax Agency area. Yainax means "little hill" in Klamath and Modoc traditional languages. Yainax Butte is a mountain south of the Klamath Reservation. The collection contains the township and range system working grids and plat maps of the Klamath Indian Allotment from 1894-1896 and plat surveys dated in the middle of the 1860s. The census provides the English name adopted by the Native American signing for the land allotment and family relationships. Charles Worden received orders to discontinue his work on this reservation on October 31, 1896 because the remaining swamplands were not subject to allotment. Allotments received some revisions by John K. Rankin. Multiple agents made township and range identifications. This collection includes working papers, notebooks, reports, and an abstract of title for several lots in Linkville established 1867, later named Klamath Falls in 1893.
