Photo of a team of men assembled beside a self-propelled steam engine and its attached threshing machine with self-feeder. Pictured in the top right is Robert Thompson with Harry Thompson beside him. On the bottom left is likely Calvin Boyd holding a grain box. The rest of the men are unknown. Threshing, which separates the inedible chaff from the edible part of grain, occurred after harvest and before winnowing. Threshing bees were held because the work was intensive and equipment was often shared within the community.
