St. John County, so named for John P. St. John, then governor of the state, was created in 1881 and the boundaries were described as follows: "Commencing at a point where the east boundary line of range 32 west crosses the 2d standard parallel south; thence west on said standard parallel to a point where the east boundary line of range 38 west crosses the said 2d standard parallel south; thence south on said range line to a point where said range line crosses the 3d standard parallel south; thence east on said standard parallel to a point where said standard parallel crosses the east boundary of range 32 west; thence north on said range line to the place of beginning." The name was changed to Logan (q. v.) by act of the legislature, approved Feb. 24, 1887.
