an  intrusive  mass  of  andesite  which  has  tilted  the  strata  and  meta- 
morphosed the  coal. 
The  rocks  adjacent  to  the  andesite  and  extending  eastward  from 
it  for  about  half  a  mite  dip  to  the  east  at  angles  ranging  from  45° 
to  80°.  East  of  this  steeply  tilted  zone  the  dips  become  less,  and  in 
the  Harmony  Mountains  the  strata  lie  almost  flat.  In  the  valley 
of  Pace  Creek,  where  the  change  in  dip  occurs,  the  relations  are 
concealed  by  abundant  vegetation  and  b}^  accumulations  of  rock 
debris,  but  a  few  exposures  show  disturbed  conditions,  and  it  is 
probable  that  faulting  has  occurred.  Whether  the  coal  continues 
but  little  disturbed  east  of  the  Pace  Creek  valley  or  has  been  cut 
off  by  a  considerable  fault  can  best  be  determined  by  drilling. 
The  following  section  of  coal-bearing  rocks  in  the  Harmony  field 
was  measured  during  the  past  summer:
