SHERIDAN    COAL   FIELD,    WYOMING.  137 
When  this  field  was  examined  in  August,  1907,  preparations  were 
being  made  to  develop  the  upper  Masters  bed  on  a  commercial  scale 
in  sec.  14,  T.  57  N.,  R.  85  W.,  where  a  section  was  made  and  a  sample 
collected  for  analysis.  An  entry  had  been  driven  300  feet  at  this 
place.

The  Masters  coal  beds  are  not  positively  known  except  between 
Tongue  River  and  Slater  Creek,  in  T.  57  N.,  R.  85  W.  One  of  the 
beds  has  been  reported  in  a  drill  record  at  the  west  edge  of  sec.  24, 
just  south  of  Tongue  River. 
A  coal  thought  to  be  one  of  the  Masters  beds  has  been  mined  for 
local  use  on  Soldier  Creek,  in  the  SE.  \  sec.  29,  T.  56  N.,  R.  85  W. 
There  was  7  feet  6  inches  of  coal  visible  in  the  drift,  and  the  base  of 
the  bed  was  not  exposed.  This  coal  seemed  to  be  equal  in  quality 
to  the  Masters  coals  on  Tongue  River. 
CARNEY    COAL    BED. 
The  Carney  coal  bed  is  exposed  at  only  a  few  places  and  these  are 
in  and  north  of  the  Tongue  River  valley.  The  best  locality  is  at  the 
Carneyville  mines  in  Carneyville,  where  extensive  mining  opera- 
tions are  being  conducted.  The  following  are  sections  of  the  bed 
at  that  place  and  at  Monarch:
