John Amos still operates his two-centuries-old grist mill in northern Harford County. The first floor of the four-story building houses the inner workings of a large water wheel used to power the grinding equipment. Milling is done on the second floor, where there are also storage bins, a machine for cracking corn into hominy, and a miller's office with desk, stove, cot, old ledgers, receipts and bills that would delight any student of early Americana. An old workbench, with tools carved or forged by hand as old as the mill itself, is found on the third floor, where Amos repairs his equipment, but with more modern power tools.
