HOW anthracite WAS MADE on of the differ ence n coal the peculiarity of the pocahontas coal is to be found in its low content of ash and volatile matter as well as of sulphur and other impurities and the resultant high percentage of fixed carbon with the high calorific value that follows upon such conditions the pocahontas vein is thought to correspond to the anthracite vein of red ah coal of the lykens valle rear Pott sill pa the geological explanation of the difference is that the anthrax te bed was subjected to a more thorough coking process under pressure than the pocahontas portion of the vein while the latter owes its own lack of volatile matter te the fact that it was subjected to heat under pressure tor a more protracted period than the bituminous coals of western pennsylvania and ohio
