ROCK, County, is bounded on the north by Dane and Jefferson, on the east
by Walworth, on the south by the State of Illinois, and on the west by Green. The county seat is at Janesville, on Rock river. It was set off from Milwaukee, Dec. 7, 1836, and fully organized Feb. 19, 1839.
The county is about equally divided between prairie and oak openings, with
no large bodies of heavy timber. It is situated on both sides of Rock river, the valley of which is as rich soil as can be found in any part of the country. The prairies are some of them quite large, but beautifully undulating, and productive in the highest degree, and are being settled and cultivated to the very center. The different varieties of soil - upland, bottom land, prairie and openings, afford facilities for cultivating all the productions of the climate to the greatest advantage - wheat upon the rolling prairies and openings - the coarser grains upon the bottom lands - and tame and wild grasses upon the low prairies and marshes, flourish best, though each class of soil is adapted more or less to all these products. It is watered by Rock river and its branches. The principle villages are Janesville, Beloit, Fulton, and Milton.
The county is in connection with the first judicial district, the second
congressional district, and is entitled to the following representation:
  • 17th Senate district, consists of the towns of Rock, Fulton, Porter, Centre [Center], Plymouth, Newark, Avon, Spring Valley, Magnolia and Union.
