"Here again there was the effort to balance a northern and southern State. Maine had been admitted into the Union in 1820, and Missouri in 1821; Arkansas in 1836, and Michigan in the next year. Now, it was proposed to admit Florida with Iowa. At this time Florida was much below the required population. The Congressional debate on the subject was a long and interesting one and brought out clearly the growing jealousy between North and South. This feeling was especially strong at this time because of the probability that several southern slaveholding States might be formed from Texas. "There was furthermore a dispute of considerable importance over the general boundary of Iowa. The Constitution submitted to Congress by the Territorial delegate provided that the boundary should be as follows: 'Beginning in the middle of the main channel of Mississippi River opposite the mouth of Des Moines River; thence up the said River Des Moines in the middle of the main channel thereof, to a point where it is intersected by the old Indian boundary line, or line run by John C. Sullivan in the year 1816; thence westwardly along said line to the old northwest corner of Missouri; thence due west to the middle of the main channel of Missouri River; thence up in the middle of the main channel of the river last mentioned to the mouth of Sioux or Calumet River; thence in a direct line to the middle of the main channel of St. Peter's River, where Watonwan River (according to Nicollet's map) enters the same; thence down the middle of the main channel of said river to the middle to the main channel of Mississippi River; thence down the middle of the main channel of said river to the place of beginning.' "An amendment was proposed in Congress which substituted the following in place of the boundary as given above: 'Beginning in the middle of St. Peter's River, at the junction of Watonwan or Blue Earth River; with the said River St. Peter's running thence due east to the boundary line of the Territory of Wisconsin in the middle of Mississippi River; thence down the middle of the last-named river with the boundary line of the Territory of Wisconsin and state of Illinois to the northeast corner of the state of Missouri in the said River Mississippi; thence westwardly with the boundary line of said State of Missouri to a point due south from the place of beginning; thence due north to the place of beginning in said St. Peter's River.'
