I am fortunate to live in York County, Pennsylvania, an area replete with scores of 19th century flour mills, many of which were prominent during the Civil War. For example, the above grist mill along the banks of the Codorus Creek in Spring Garden Township was owned in 1863 by Josiah E. Myers. Typical of millers of the era, he grew or purchased oats, rye, corn, and or wheat to make flour and other products for commercial sale. He also did consignment work for other farmers. In other words, area farmers could bring in a few bushels of their own grain, and Myers would mill it for them for free, with his compensation being a percentage of the ground flour.
