In  general,  the  roof  of  this  coal  is  sandstone,  while  the  partings  may  be  either  bone  or 
fire  clay. 
OHIO   DISTRICT. 
The  geological  section  in  the  hills  of  Ohio  opposite  Ashland  is  really  a  continuation  of 
that  on  the  Kentucky  side.  Both  coals  Nos.  6  and  7  are  of  importance  and  both  have  been  • 
worked.  At  the  present  time  coal  No.  6  is  being  mined  at  Coalgrove  and  shipped  to  Ports- 
mouth, Ohio.  Nothing  on  a  commercial  scale  has  been  attempted  within  the  last  thirty 
years  on  the  next  higher  or  Sheridan  seam,  though  much  valuable  unworked  coal  remains 
above  drainage  in  the  western  two-thirds  of  Perry  Township."  The  next  higher  coals  in 
the  series,  the  No.  8,  or  Hatcher  seam,  and  No.  9,  are  of  local  importance  only. 
LITTLE    SANDY    RIVER    DISTRICT. 
The  Little  Sandy  district,  so  far  as  coal  resources  are  concerned,  is  coincident  with  the 
territory  having  its  outlet  to  the  north  by  way  of  the  Eastern  Kentucky  Railroad,  for  to  the 
west  and  south,  from  Leon  to  Rosedale,  Carter  County,  the  coals  are  too  small  to  be  worked 
except  for  local  country  use.  In  the  following  paragraphs  will  be  considered  those  impor- 
tant coals  lying  in  the  drainage  of  Little  Sandy  River  north  of  the  Chesapeake  and  Ohio 
Railway. 
The  Little  Sandy  country  lies  well  toward  the  western  edge  of  the  basin,  and  hence  the 
coals  occurring  in  this  territory  must  be  the  lower  seams.  All  the  coals  of  any  importance 
lie  below  the  "Ferriferous"  limestone  and  above  the  Greenbrier  limestone.  The  lowest 
coal  in  the  region  is  the  "subconglomerale  seam  "  developed  on  Barrett  Creek,  Carter  County, 
and  Canes  ('reek,  Greenup  County.  I)  can  not  have  more  than  local  importance,  owing 
to  its  thinness.  At  least  two  coal  horizons  occur  between  this  "  subeonglomerat  e "  coal 
and  the  so-called  "clod  seam"  of  the  Argillite  region.  The  latter  seam,  owing  to  a  thick 
"clod,"  or  clay  part  ing,  lias  lit  t  le  value  except  as  a  local  fuel.  It  has  been  opened  at  many 
points  in  the  hills  near  Dan  ley  ton  and  Argillite,  on  Culp  Creek  and  Henry  Branch,  as  well 
as  in  the  hills  near  Hunnewell.  It  occurs  on  both  sides  of  Little  Sandy  River,  but  the  east- 
erly dips  carry  ii  below  drainage  as  the  Louisville  and  Lexington  Railroad  is  approached} 
At  a  country  bank  one-fourth  of  a  mile  west  of  Danlevfon,  Greenup  County,  the  following 
section  was  measured:

The  coal  is  of  the  splinty  variety  and  the  large  number  of  openings  on  it  indicate  that  it 
is  highly  valued  as  a  local  fuel.  Coal  No.  3,  the  stratigraphic  equivalent  of  the  Torch- 
light seam  of  the  Big  Sandy  River  region  is  present  in  all  the  hills  of  this  region.  In  general, 
it  is  above  drainage  on  this  side  of  the  basin  only  to  the  west  of  the  Louisville  and  Lexing- 
ton Railroad.  At  Boghead  and  Hunnewell  this  seam  contains  an  important  cannel  bench, 
as  the  following  section  at  Boghead  shows:
