these  shale  partings,    "knife  blades"  of  sulphur  are  abundant,  but 
generally  the  coal  bed  is  free  from  clay  veins  and  "faults." 
The  following  sections  show  the  general  character  of  the  coal:

Directhy  beneath  the  coal  lies  a  fine  bed  of  fire  clay  about  6  feet  thick 
that  makes  good  tile  when  worked  up  in  a  pure  state  and  a  good  grade 
of  buff  brick  when  mixed  with  its  own  bulk  of  brown  shale. 
Quality  of  the  coal. — Very  little  data  are  at  hand  to  show  the  uses  to 
which  this  coal  is  put.  The  Beech  Creek  Coal  and  Coke  Company 
report  it  an  excellent  steam  coal,  but  as  it  is  not  coked  in  this  region 
its  fitness  for  that  purpose  will  have  to  be  judged  from  its  composition. 
A  sample  about  2  inches  wide  and  1  inch  thick  was  cut  from  roof  to 
floor  of  a  working  face  of  the  bed  in  the  Beech  Creek  No.  3  mine  at 
Patton.  In  sampling,  all  partings  were  excluded,  and  the  following 
analysis  was  made  by  Mr.  W.  T.  Schaller,  of  the  United  States  Geolog- 
ical Survey:
