ta  eokiDg  rajHdly,  this  coal  dischai^s  gas  copiously,  intumesces
ongly,  forming  a  coherent  porous  mass,  moderately  tough,  and  of  a
rf-gray  eolour.  By  coking  more  slowly,  the  consistence  is  more  com-
tt  and  tough ;  and  by  very  slow  treatment,  the  powder  is  scarcely  ren-
nd  in  any  degree  coherent.  The  coke  of  this  coal  is  well  adapted  for
siting  iron.
