From  8  to  16  feet  below  this  bed  occurs  another  bed,  of  which  the

Turner  coal.— In  the  low  hills  east  of  the  mouth  of  Bennett  Fork 
occur  two  coals  whose  nearness  to  each  other  suggests  the  Bennett 
Fork  coals,  but  which  it  is  believed  lie  200  feet  below  them.  The 
lowest  of  these  coals  is  worked  at  the  Turner  mine  and  at  other  open- 
ings on  both  sides  of  the  ridge.  Almost  nothing  is  known  of  its 
workability  outside  of  the  region  mentioned,  as  it  is  below  drainage 
level.     A  typical  section  shows:

STRATIGRAPHY   AND    COALS    OF    HARLAN    DIVISION    OF    FIELD. 
Unlike  the  western  portion  of  the  field  just  discussed,  this  eastern 
part  has  seen  no  development  and  very  little  exploration.  The  facing 
of  a  coal  bed  in  this  area  is  an  operation  calling  for  the  service  of  two 
men,  usually  for  two  or  three  days,  and,  in  view  of  the  lack  of  trans- 
portation facilities  and  the  fact  that  good  workable  coal  is  usually 
found  low  in  the  mountains  in  the  eastern  part  of  the  field,  the  neces- 
sary incentives  have  been  lacking,  and  as  a  result  the  data  obtained 
have  had  to  be  almost  all  gotten  from  the  few  and  scattered  exposures 
naturally  faced  in  stream  cuttings.     Therefore  the  knowledge  of  the
