Locality  No.  16:  At  locality  No.  16,  1  mile  S.  20°  E.  from  No.  15, 
the  following  section  was  taken  immediately  above  the  basal  sand- 
stone, showing  coal  bed  A  and  small  related  beds :

Locality  No.  17:  One  mile  N.  52°  W.  from  locality  No.  16,  bed  A 
shows  a  thickness  of  4  feet  7  inches,  with  a  sandy  shale  parting  toward 
the  top  varying  from  1  to  2  inches.     The  following  is  the  section  at 
this  place:

Locality  No.  18:  At  locality  No.  18,  about  3|  miles  north  of  east 
of  Raton  Spring,  beds  B  and  C  are  exposed.  These  beds  are  much 
burned  in  the  vicinity,  and  the  red  baked  shale  stands  out  in  marked 
contrast  to  the  surrounding  rocks,  affording  a  reliable  guide  in  tracing 
the  coal  beds.  A  section  was  measured  at  the  head  of  an  arroyo, 
where  erosion  has  removed  the  greater  part  of  the  burned  material. 
The  relations  at  tins  point  are  as  follows:
