The  On*  mine  is  situated  on  a  branch  of  Meeteetse  Creek,  about  3 
miles  northwest  of  Wise  post-office.  This  mine  is  well  opened  with 
a  double,  well-timbered  tunnel,  extending  100  feet  from  the  outcrop. 
The  deposit  consists  of  two  benches,  each  3  feet  thick,  separated  by  a 
layer  of  light  bluish-gray  slate  which  is  characteristic  of  this  horizon. 
The  coal  occurs  in  the  basal  sandy  series,  and  in  appearance  is  black, 
with  a  bright  luster,  brown  streak,  and  uneven  fracture.  It  has  a 
rather  high  per  cent  of  fixed  carbon,  a  moderate  amount  of  volatile 
matter,  and  a  low  moisture  content.  This  mine  is  worked  during  the 
winter  months  with  a  seasonal  output  of  300  to  400  tons.  Consider- 
able prospecting  has  been  done  near  the  Orr  mine,  and  one  opening 
has  been  made  about  a  mile  south  which  exposes  a  6-foot  bed  of  excel- 
lent coal. 
The  Blake  mine  is  located  about  3  miles  above  Meeteetse,  on  the 
north  bank  of  Gray  Bull  River.  Here  a  vein  5  feet  9  inches  thick  has 
been  extensively  operated,  and  is  one  of  the  oldest  openings  in  the 
district.  The  dip  of  the  beds  is  9°  northeast.  The  main  tunnel  is 
about  150  feet  in  length,  with  several  side  entries.  The  workings  are 
too  low  in  the  river  bank  for  perfect  drainage  to  be  effected,  and  some 
little  difficulty  has  resulted  from  this  condition.  Operations  were  first 
begun  at  this  place  in  1892,  but  there  was  only  a  small  output  until 
1898,  when  the  property  was  purchased  by  the  present  owners.  The 
total  production  during  the  past  four  3^ears  has  exceeded  2,000  tons. 
In  1902  the  product  amounted  to  900  tons  with  a  market  value  of  $2 
per  ton  at  the  mine.  There  is  another  opening  on  the  same  horizon, 
a  short  distance  up  the  river,  owned  by  McDonald  &  Cottle,  of 
Thermopolis.  The  dip  in  this  region  is  low  and  the  conditions 
are  generally  favorable  for  more  extensive  development  of  these 
properties.
