I don't know (and I guess I never will while I'm alive) just how thick my old skull is, but I do know that it is pretty thick, or it would have been cracked many years ago, for I have been struck some terrible blows on my head with iron dray-pins, pokers, clubs, stone-coal, and bowlders, which would have split any man's skull wide open unless it was pretty thick. Doctors have often told me that my skull was nearly an inch in thickness over my forehead.
