Yesterday I was given a tour through Morgantown's Easton Roller Mill. Construction started a year before the Civil War ended and finished two years afterward. At the time, the town of Easton was even more populous than Morgantown.
The mill was open to the community, and its operators usually charged a percentage of the flour, grains or corn in return for its use. Some of the equipment still present is really quite ingenious, and entering the location is a fascinating step backward in time.
