OCONTO, County, is bounded on the north by the State line, on the east by the middle of Green Bay and a portion of Brown, on the south by Brown and Outagamie, and on the west by Waupacca and Marathon. It was set off and established from Brown, February 6, 1851, and organized for county purposes April 7, 1852. The principal rivers are Pishtego, Oconto, Pensaukee, and Little Suamico. The judicial connection of Oconto is with Brown, and representative with Outagamie. The chief product of this county, thus far, has been pine lumber, which is produced in great quantities; but little is known of its agricultural advantages.
