Jan. 9, 1840, the Wisconsin legislature created a new county out of Crawford county, including territory west of the Chippewa river, extending northward to the British possessions, and named it St. Croix. By the same act, a day was designated for an election, at which a county seat was to be chosen and county officers elected. "Mouth of St. Croix," now Prescott, and Caw-caw-baw-kang, now St. Croix Falls, were designated as voting places. Two places only were voted for, "Mouth of St. Croix," and Dakotah, Brown's claim, now Schulenberg's addition to Stillwater. Dakotah was chosen by a vote of forty-five to thirteen. The returns were made to Prairie du Chien, county seat of Crawford county, and certificates issued to the county officers elected by C. J. Leonard, clerk of Crawford county. The legislature had at the time of creating the new county made it a probate district, Philip Aldrich being appointed judge. The history of the county until 1848 has been given elsewhere, as connected with the early history of Stillwater. The admission of Wisconsin Territory as a state in 1848 divided the county, giving it the St. Croix river and state line as its western boundary. The Wisconsin portion of the old county was consequently left without a county seat, while the portion west of the St. Croix had a county seat, but was without state or territorial jurisdiction. Congress, however, declared Wisconsin territorial laws to be still in force in the excluded territory, and they so remained until the organization of Minnesota Territory. Soon after the admission of Wisconsin, that part of St. Croix county within its limits was reorganized for county and judicial purposes, and a new county seat chosen, located in section 24, township 29, range 19, at the mouth of Willow river. This county seat was at first called Buena Vista. On Sept. 9, 1848, the county commissioners, under the law creating the county, held their first meeting at the county seat, in the house of Philip Aldrich. The commissioners present were Ammah Andrews, chairman; W. H. Morse, and W. R. Anderson, clerk. Philip Aldrich was appointed treasurer. Four voting precincts were established, Mouth of St. Croix, Willow River or Buena Vista, Osceola, and Falls of St. Croix. These early commissioners performed duties of the most varied character incident to the government of a new county. There was as yet no county seal, and they were required to draw with the pen upon legal documents a scroll representing a seal, and to use other forms, appliances and devices without legal precedent.
