His first appearance in Beloit business circles was in 1845, when he engaged in general merchandising on a large scale for three years, removing in 1849 to Cambridge, Dane county, where he again engaged in milling, owning the town site and several mills; sold out here in 1851 and bought a town site in Avon township and 3,000 acres of land and opened a large store and constructed a water power plant, but in 1852 sold out here and returned to Beloit to establish his permanent home.
