Riley County, one of the counties organized by the first territoriai legislature in 1855, is the second county east of the 6th principal meridian, the second south from Nebraska, and the fifth west from the Missouri river. It is bounded on the north by Washington and Marshall counties; on the east by Jackson and Shawnee; on the south by Wabaunsee and Geary, and on the west by Geary and Clay. As originally organized its eastern and western boundary lines were almost identical with those of Marshall county extended south, and the southern boundary was the Kansas river. Between the years 1857 and 1873 several changes were made in the county lines. The eastern line was moved west to the Big Blue river; the western 8 miles west to the present location; Geary county was enlarged from Riley county territory, and additions were made to the latter from Wabaunsee and Geary, forming one of the most irregularly shaped counties in the state.
