WARRIOR    COAL    BASIN,   ALABAMA.  217 
Farther  southwest,  in  the  SE.  |  sec.  16,  T.  17  S.,  R.  31  W.,  the  following  section  was 
measured  at  an  old  mine  in  what  appears  to  be  the  Mary  Lee  seam:

A  seam  outcropping  in  the  road  to  Republic.,  about  one-fourth  mile  north  of  its  inter- 
section with  the  Pratt  City-Birmingham  road,  is  probably  Mary  Lee.  The  only  other  point 
at  which  coal  was  seen  that  is  possibly  an  outcrop  of  this  seam  is  in  Wylam,  near  the  siding 
to  Pratt  No.  5  mine  and  about  midway  between  the  mine  and  the  post-office.  At  this 
point  a  vertical  outcrop  shows  the  following  section:

The  position  of  this  outcrop  with  regard  to  that  of  the  Pratt  seam,  together  with  the 
dip  of  the  strata,  suggests  that  the  coal  is  Mary  Lee,  though  it  may  be  some  other  seam 
of  the  Mary  Lee  group.  On  account  of  the  weathering  and  crushing  which  the  coal  has 
undergone,  the  above  section  probably  does  not  correctly  represent  its  character  in  this 
locality. 
Diamond-drill  holes  in  the  center  of  the  basin  show  the  Mary  Lee  coal  to  be  of  good 
thickness  It  probably  is  a  minable  seam  throughout.  Analyses  Nos.  15-20  of  the  table 
on  page  221  show  the  composition  of  the  coal.     It  is  coked  and  also  used  as  a  steam  coal. 
Blue  Greek  seam. — So  far  as  known,  the  Blue  Creek  coal  seam  is  of  value  only  in  the 
northeast  end  of  the  southern  field,  west,  north,  and  east  of  Morris.  The  seam  is  of  good 
thickness  in  this  region,  but,  like  the  other  seams  of  the  Mary  Lee  group,  it  is  very  dirty, 
as  shown  by  the  following  average  of  six  sections  measured  at  different  points:

The  partings  are  so  distributed  that  generally  there  is  no  clean  bench  of  coal  over  14 
inches  thick.  In  only  one  section  is  there  a  clean  bench  18  inches  thick.  In  sec.  27,  T.  15 
S.,  R.  2W.,  the  Blue  Creek  seam  reaches  a  great  thickness,  but  is  so  full  of  partings  as 
to  be  nearly  worthless.     Below  is  the  section  at  this  point:
