1. Eagle Roll Mills Marker

Inscription. This pair of roll mills, built in 1839, produced the finest Eagle brand sporting powder. In 1886, an iron water turbine replaced the original wooden water wheel that powered the mills. In this step the ingredients sulphur, saltpeter, and charcoal were mixed together, or "incorporated," under two revolving eight-ton cast-iron wheels. After rolling, the powder, called "wheelcake," was shoveled into tubs and transported to the Press House.

Erected by Hagley Museum.
