As a group, these lowiron alloys, called ferroalloys, can be readily dissolved in steel to impart predictable properties according to the type and amount of metal added. For the first time, steels could be tailormade for such properties as toughness, impact strength, high strength at high temperatures, and corrosion resistance.
They charged a toll for grinding your corn if you did not have the money to pay for the grinding. The post office was in the Davidson store and Frank Davidson was the postmaster. The post office was later moved to Walt Phifer's Store on the north prong of Harmons Creek.
Coal is usually dropped into the ovens through openings in the roof, and heated by gas burning in flues in the walls within the coke oven battery.
