SKETCH / of / The Public Surveys / in / IOWA TERRITORY

Description
The Iowa Territory was created in 1838. This map, created under the auspices of the General Land Office, divided the eastern part of that land into square townships 6 miles on each side (townships at the edges of the state tend to be smaller and irregular in shape). The scale is 18 miles to the inch.
The identified towns include Bellevue, Benton, Bloomfield, Bloomington, Centerville, Davenport, DuBuque, Farmington, Franklin, Iowa City, Jefferson, Lyons, Marengo, Mt. Pleasant, Moscow, N. York, Peru, Rochester, Rockingham, Salem, Tuscarorah, Van Buren, Washington, and West Point. Towns in Illinois include Cassville, Ft. Armstrong, Ft. Madison, and Rock Island. A Principal Meridian runs just east of Salem, and 1st and 2nd correction lines run east and west.
Much of the underlying survey was done by William A. Burt, inventor of the solar compass.
