The  Burgin  mine,  also  known  as  the  Squaw  Smith  mine,  one  of  the 
oldest  in  the  neighborhood,  is  located  in  the  SE.  \  SE.  \  sec.  26,  T.  4  S., 
R.  22  E.,  on  the  north  bank  of  Elbow  Creek,  2\  miles  south  of  Joliet, 
Mont.  It  is  owned  by  the  Joliet  Coal  and  Fuel  Company  and  is  oper- 
ated by  Barrett  Brothers.  Formerly  it  supplied  only  the  local  de- 
mand, but  since  the  extension  of  the  railroad  up  Rock  Creek  coal  is 
hauled  to  Joliet  in  wagons.  Mining  is  done  by  hand,  following  the 
room  and  pillar  s}rstem.  The  dip  of  the  strata  is  5°  W. ;  the  strike 
is  north.  The  bed  is  said  to  improve  in  quality  toward  the  west.
