impossible  to  secure  a  detailed  measurement,  but  the  coal  bed  appears  to  be  the  same  as 
thai  operated  at  the  Sinister  mine  and  to  have  a  similar  thickness.  Six  coal  seams  show 
on  the  north  side  of  the  creek  in  a  section  about  230  feel  thick.  The  sandstone  and  eoali 
beds  dip  about  45°  W. 
The  middle  coal  group  outcrops  near  the  summit  of  the  bluff  on  the  west  side  of  Oak  Creek, 
about  500  feet  above  the  Sinister  mine.  The  outcrops  appears  to  be  continuous  from  tins'] 
point  to  Eddy  post-otHce,  but  only  prospect  pits  were  found,  and  these  seemed  to  indicate 
that  the  coal  beds  are  not  so  valuable  as  are  those  of  the  lower  group  in  this  locality. 
Trout  Creek  Canyon  district.  A  number  of  coal  seams  are  exposed  on  upper  Trout  Creel 
near  the  mouth  of  the  canyon,  about  0  mil*  s  above  Eddy  post-office.  The  seams  are  opened 
near  the  road  that  crosses  from  Oak  Creek,  and  they  probably  occur  in  the  middle  coal  grouj 
About  three-fourths  of  a  mile  above  this  point  another  group  of  coal  seams  has  been  pros- 
pected. These  probably  belong  to  the  lower  group,  which  is  thought  to  follow  down  Trout 
Creek  on  the  crests  of  the  ridges  in  approximately  horizontal  position  from  Pinnacle  post 
office  to  near  the  mouth  of  Trout  ('reek  Canyon,  where  this  coal  group  suddenly  dips  beloi 
water  level.  On  one  of  these  seams  of  the  lower  group  an  entry  has  been  driven  in  40  feet 
showing  6  feet  3  inches  of  coal  (B).  The  coal  was  slight  ly  weathered,  but  a  sample  cut  aci 
the  face  of  the  seam  gave  the  following  analysis:

Eddy  district.     The  middle  and  lower  coal  groups  cross  Trout  Creek  in  the  vicinity  of 
Eddy  post-office,  and  mines  and  prospects  show  that  both  groups  carry  workable  coals.     A 
coal  bed  of  the  lower  group  is  opened  at  the  Jones  mine,  on  t  he  north  side  of  Trout  Creek,  1 
mile-  below  Eddy.     The  coal  is  nearly  horizontal  and  shows  the  following  section:

This  coal  group  contains  a  number  of  thick  beds,  as  shown  by  the  section  on  the  county 
road  which  crosses  Trout  ('reek  2  miles  below  Eddy. 
The  middle  group  of  coals  has  been  opened  on  the  Hutchinson  property  on  Middle  Creek 
(C),  just  above  the  crossing  of  the  public  road  west  of  Eddy.  The  principal  scams  shows 
a  thickness  of  !)  feet  6  inches  of  clear  coal  in  the  mine  near  Mrs.  Hutchinson's  house.  A 
-ample  for  analysis  was  taken  at  a  new  opening  a  few  rods  down  the  creek.  This  sample 
"was  obtained  by  making  a  cut  across  the  lower  part  of  the  seam  and  represents  a  thickness 
of  5  feet  of  coal.     The  analysis  is  as  follows:
