“ The city derives considerable commercial importance from its situation in an extensive farming and stock-raising section, and is known for its large cement works and flouring mills. There are also grain elevators, brick yards, and breweries. Under the revised charter of 1885, the government is vested in a mayor, chosen annually, and a unicameral council. The water-works are owned and operated by the municipality. Yankton was settled in 1862 and received a city charter in 1883. ”
