The  Hartshorne  bed,  though  variable  somewhat  in  composition  in 
different  parts  of  the  held,  produces  a  high-class  bituminous  coal  in 
the  McAlester  district  and  a  semibituminous  coal  in  the  eastern  part 
of  the  field.  It  is  also  a  successful  coking  coal.  It  has  been  coked 
with  the  McAlester  coal  at  Alderson,  Buck,  and  Krebs,  and  is  used 
exclusively  in  a  battery  of  SO  ovens  at  Howe. 
The  lowest  coal  in  the  Lehigh  district,  at  the  extreme  southern  end 
of  the  district,  is  presumably  the  same  as  the  Hartshorne,  but  its 
exact  relations  are  not  now  determinable,  on  account  of  local  disturb- 
ances of  the  rocks  in  the  cast  side  of  the  Lehigh  basin.  This  bed  is 
locally  known  as  the  Atoka  coal,  and  has  been  prospected  at  many  lo- 
calities, but  has  been  mined  only  to  a  limited  extent.  So  far  as 
known,  the  coal  varies  between  3  feet  0  inches  and  5  feet,  aver- 
aging approximately  4  feet  thick,  and  is  generally  clear  of  shaly  im- 
purities. The  quality  of  the  coal,  however,  is  not  so  high  as  that  of 
the  Hartshorne  coal  at  McAlester,  Hartshorne,  and  other  places  along 
the  outcrop  farther  east,  but  its  value  as  a  steaming  coal  is  proved 
3y  its  use.  Between  Muddy  Boggy  Creek  and  Reynolds  station,  on 
the  Missouri,  Kansas  and  Texas  Railroad,  the  rocks  in  the  strike  of 
the  coal  are  tilted  at  steep  angles,  but  nothing  is  known  of  the  thick- 
ness or  quality  of  the  coal. 
A  coal  bed  believed  to  be  the  lower  Hartshorne  has  been  located  by 
prospecting  between  the  Missouri,  Kansas  and  Texas  Railroad  and 
Haileyville.  Prospect  mines  and  pits  show  the  coal  to  be  4  feet 
ind  4  feet  9  inches  in  thickness.  It  is  believed  that  the  coal  occurs 
dso  southwestward  from  the  vicinity  of  Savanna  in  a  sharp  anticlinal 
fold.  On  the  sides  of  this  fold  it  is  for  the  most  part  steeply  inclined 
it  the  outcrop,  but  the  dips  grow  gradually  less  downward.  The 
ower  Hartshorne  coal  in  the  Hartshorne  basin  eastward  ami  north- 
ward from  Haile}^ville  has  been  prospected  extensively,  and  mining 
>perations  have  been  carried  on  for  a  number  of  years.     The  Harts-
