9/29/17 B: Iron -Concentrated in a few regions -Hanging Rock region Pig iron process: 1 ton pig iron goes through a furnace (see powerpoint) Requires 150-200 bushels charcoal, 5000 lbs iron ore, 300 lbs limestone Drains out in something called piglets 12-15 tons every day produced -Southeast Ohio was one of the centers of the industrial revolution 1849: 22 furnaces 1865: 45 furnaces -furnaces going simultaneously; source of ammunition during the Civil War, south sent an army to stop some (another story) -investment in furnaces paid off incredibly with a 100% return So what? This course is about forests . (Matlack got sassy) 2: Impact on Forest -Charcoal! (wood that has been roasted to drive off water, sulfur, etc, and leaves only carbon) -Charcoal =/= Coal How do you make charcoal? You cut down trees. Cut them down, cut them up, put them in a pile (meiler), and light them on fire (bonfire!). But you cover the whole thing with dirt so that the dirt limits the excess oxygen.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
