and  has  been  opened  at  a  few  points  near  Summit.  Its  horizon  is  also  above  drainage  or 
Lick  Creek  and  Left  and  Right  forks  of  Little  Blaine  Creek.  For  the  present  this  coa. 
may  be  tentatively  correlated  with  the  "clod  seam"  of  the  Little  Sandy  River  region. 
The  next  higher  coal  of  economic  significance  in  this  region,  No.  3  of  the  Kentucky 
Survey,  may  be  referred  to  the  Mercer  group  of  the  Pennsylvania  section.  This  is  among 
the  most  persistent  of  the  workable  coal  beds  in  the  quadrangle.  As  already  mentioned, 
on  Levisa  Fork  at  Torchlight  station  it  occurs  HO  feet  above  the  "little  cannel"  scam, 
disappearing  below  drainage  about  a  mile  from  the  mouth  of  Threemile  Creek.  It  is- 
found  in  the  hills  south  of  a  line  drawn  from  Torchlight  to  Prosperity,  and  has  been  opened 
at  a  number  of  points  on  Lick  Creek  and  Right  Fork  of  Little  Blaine  Creek,  showing  a 
rather  persistent  and  characteristic  section.  This  fact,  together  with  its  massive  sandstone 
roof  and  its  position,  from  120  to  140  feet  below  the  Ilomewood  sandstone,  serve  to  identify 
it  readily.  A  typical  section  is  that  at  the  Torchlight  mine,  the  three  benches  of  the 
main  body  of  coal  varying  in  thickness  as  the  seam  is  traced  to  the  west.

The  next  higher  coal.  No.  1  of  the  Kentucky  series,  is  not  a  very  important  bed,  except 
in  two  restricted  localities,  namely,  in  the  hills  east  and  west  of  Levisa  Fork  and  in  the 
dividing  ridges  between  Stinson  and  Straight  creeks,  Carter  County.  It  usually  occurs 
near  the  base  of  the  Ilomewood  sandstone,  in  some  cases  directly  under  this  horizon,  as 
on  Catletts  Creek,  Boyd  County.  At  Torchlight  it  is  found  55  feet  above  coal  No.  'A,  where 
it  shows  the  following  section:

It  will  be  noted  that  the  main  section  of  coal  shows  two  benches — a  condition  which 
exists  where  the  coal  outcrops  along  Lick  Creek  and  also  on  the  Kentucky  side  of  Ohio 
River  near  Ashland  and  Cat  let  tsburg.  The  Lick  Creek  coal  lies  from  70  to  80  feet  above 
coal  No.  3  and  is  the  thickest  coal  observed  in  the  quadrangle.  A  few  sections  obtained 
from  openings  on  the  property  of  the  Louisa  Coal  Company  in  the  divide  between  Lick 
Creek  and  Levisa   Fork  will  well  illustrate  the  character  of  this  seam.
