Rush County, west of the central part of the state, is the fifth county north from Oklahoma, the fourth south from Nebraska, and the sixth east from the west line of the state. It is bounded on the north by Ellis county; on the east by Barton; on the south by Pawnee, and on the west by Ness. It was named in honor of Capt. Alexander Rush, who was killed at Jenkins' Ferry, Ark. The boundaries were described in the creative act as follows: "Commencing where the east line of range 16 west crosses the 3d standard parallel; thence south to the 4th standard parallel; then west to the east line of range 21 west; thence north to the 3d standard parallel; thence east to the place of beginning." By an act of the legislature in 1873, the southern tier of townships was taken off and the present boundaries established.
