Above is a depiction of how a 1740 mill would have looked. Notice the hydro-powered wheel and smoke coming from the chimney, and in Peter's case oil shale would have been burning. Oil shale burned hotter and cleaner than coal and would have created much more refined steel than iron created with coal and its by-product, carbon. Wood placed above the extremely hot oil-shale would have been seasoned with vaporized oil fumes and wood would have been ready to use in about 3-days as opposed as 3-years curing outside. Wood treated this way did not shrink, even 270 years later, wood that was treated with oil-shale looks as new as they day it was cut, and it is hard as a rock. This is proved in the house on Bakers Lookout, wood appears brand new but is 270 years old. What a wonderful secret Peter Studebaker brought to this country.
