Would anyone know what the term "Illinois mange" would refer to, in about 1840? I've been reading a novel, set in southern IL in that time period; apparently it was some sort of seasonal affliction that struck pioneers who were breaking the soil for the first time. If left untreated too late, apparently it was fatal. I tried to google this, but google, in its wisdom, decided I just can't spell and gave me references to things MANAGED in Illinois -- and also a recipe for blanc mange. Thanks, Jane
