shafts  and  slopes  have  been  sunk,  which  give  a  fairly  good  idea  of  the 
number  and  thickness  of  the  coal  beds.     The  oldest  work  of  this  kind 
is  a  slope  150  feet  long,  sunk  on  a  coal  bed  that  shows  on  the  north 
side  of  the  basin,  near  the  old  Indian  trail  from  Dudley ville  to  San 
Carlos,  which  crosses  Mescal  Mountain  near  the  triangulation  station. 
Recently  a  shaft  has  been  sunk  in  the  next  ravine  south  of  the  slope, 
and  presumably  the  same  bed  of  coal  has  been  cut.     The  shaft  section 
is  as  follows:

The  shaft  was  extended  20  feet  below  the  coal  bed  in  search  of  other 
coals,  but  nothing  was  found.  It  was  the  intention  of  the  prospector 
to  sink  to  the  limestone,  but,  owing  to  trie  great  depth  and  difficulty  of 
hoisting  the  material  by  hand,  the  work  was  abandoned  at  a  depth  of 
160  feet.  This  shaft  is  120  feet  south  of  the  Reed  slope  and  is  gen- 
erally known  as  the  Reed  shaft.  In  the  slope  the  coal  is  considerably 
disturbed  by  faulting  and  minor  folding,  so  that  it  varies  in  thickness 
from  point  to  point.  The  following  sections  were  measured  where  the 
coal  is  undisturbed,  and  consequently  represent  its  true  structure  and 
thickness.  About  75  feet  from  the  mouth  of  the  slope  the  coal  has 
the  following  section:
