248  CONTRIBUTIONS    TO    ECONOMIC    GEOLOCY,   1905. 
The  McBroom  mine  is  working  on  the  upper  eoa]  bed  and  the  Monero  mine  on  the  lower 
bed  of  this  group.  The  main  gangway  of  the  latter  is  driven  down  on  the  slope  of  the  coal 
for  about  1,600  feet.  A  sample  for  chemical  analysis  was  taken  from  this  mine  in  the  same 
manner  as  from  the  Kutz  mine.  The  material  of  the  sample  was  obtained  from  a  cut  made 
across  the  entire  face  of  the  eoal  bed  33|  inches  in  thickness.  The  result  is  shown  in  anal 
ysis  No.  13  in  the  table,  on  page  258.  The  analyses  of  the  samples  from  the  two  mines  are 
very  similar,  except  in  the  amount  of  sulphur  and  ash.  The  percentage  of  sulphur  in  the 
Kutz  sample  is  remarkable,  and  exceeds  that  in  any  other  sample  obtained  from  this  held. 
Aside  from  the  ash  and  sulphur  there  is  a  greal  similarity  in  the  composition  of  the  two 
samples,  and  they  both  rank  as  fairly  high  grade  bituminous  coals. 
The  output  of  the  district  is  about  40,000  tons  per  year,  three-fourths  of  which  is  from 
(he  Monero  mine.  About  15  per  cent  of  the  total  product  is  line  coal,  which  now  is  wasted 
for  lack  of  coking  facilities.  Eighty  per  cent  of  the  merchantable  coal  is  used  by  the  Den- 
ver and  Rio  <  i ramie  Railroad  for  locomot  ive  coal.  12  per  cent  goes  to  the  New  Mexico  LunJ 
ber  Company,  and  the  remainder  is  used  in  home  consumption  and  a  limited  commercisi 
trade. 
Heretofore  the  coal  has  sold  readily  for  $1.50  per  ton.  but  at  present  the  ruling  price  is 
$]  .25  per  ton.  The  Rio  Arriba  Coal  Companj  ,  which  operates  the  Monero  mine,  est  imates 
the  coal  now  in  sight  on  its  ground  at  5,000,000  tons,  which  will  enable  this  mine  to  con- 
iinue  it-  present  rate  of  production  for  considerably  more  than  a  century. 
At  Lumberton  the  coal  has  been  worked,  but  only  to  supply  the  local  demand.  The 
beds  dip  slightly  to  the  west,  but  they  are  more  broken  by  faults  than  at  Monero.  The 
following  section  was  measured  in  a  gulch  1  mile  southeast  of  Lumberton:

The  coal  beds  seem  to  grow  thin  south  of  Monero,  as"  shown  by  the  following  section 
which  was  measured  near  Morse  Lake:

STINKING    LAKE    DISTRICT. 
The  Stinking  Lake  district  lies  west  of  Chama  River  and  Elvado,  and  extends  from 
Boulder  Lake  southward  beyond  Stinking  Lake.  It  drains  east  into  Chama  River.  Xo 
mines  have  been  opened  in  this  district.  Some  good  coal  is  present,  but  probably  it  does 
»*ot  occur  over  largt    areas  or  in  promising  quantities.     The  Mesaverde  IS  the  coal-bearing
