The 1870s saw significant economic and demographic growth in Horsham. During this period the foundry, the hospital, and the Horsham Agricultural Society were established, with the first Horsham show held in 1876. Geoffrey Blainey, notes in his "History of Victoria", that the Victorian railway building boom of the 1870s enabled large-scale wheat production to begin in the Wimmera. He also describes a unique migration of German farmers, mostly Lutherans from South Australia, who travelled across east in covered-wagons along with their families and herds of cattle and then settled in the Wimmera district. Blainey writes that "nothing in Australian history so resembles the opening of the American west as this trek of farmers to the Victorian plains in the 1870s'." Farming production in the region dramatically increased, and wheat was established as the dominant agricultural crop.
