As about a half-dozen fellow workers stood idle with their hands in their pockets when this photo was taken, these two hard-working chaps were keeping their hands (if not their noses!) milling this three-ton grindstone at the foundry as photographed here!

As a footnote, have you ever wondered where grindstones came from and their fokelore? In addition to the above please refer to [id=191712842] and [id=191713345]
