At state agricultural exhibitions farmers could earn premiums for top animals and crops or diplomas and medals for trades goods, farm equipment, arts and crafts of various kinds.
The 1860 exhibition was held in Portland.
William C. Hammatt of Howland was president and Ezekiel Holmes of Winthrop, sometimes called the "father of Maine agriculture," was secretary of the Maine State Agricultural Society, which sponsored the exhibition.
Holmes published the Maine Farmer.
