Wheat farming boomed in the late 19th century, in part because of improvements in harvesting technology, particularly the automated reaper/binder that relied on twine to tie wheat into bundles for threshing. In 1899, to meet the rising demand for twine and confront International Harvester's monopolization of twine production, North Dakota and other Great Plains states set up their own twine factories using prison labor. | Wheat farming boomed in the late 19th century, in part because of improvements in harvesting technology, particularly the automated reaper/binder that relied on twine to tie wheat into bundles for threshing.
