of  what  may  be  expected  of  this  bed  in  that  region,  but  it  is  believed 
that  the  area  in  which  this  coal  is  workable  will  extend  northeast 
from  Hominy  Falls  toward  Addison,  and  probably  beyond  the  con- 
fines of  the  quadrangle.  Analyses  of  this  coal  in  this  region  show  it 
to  stand  up  well  with  the  Sewell  coal,  as  that  is  now  being  worked 
along  New  River.  The  average  of  a  large  number  of  analyses  shows 
as  follows:

The  New  River  coals  pass  below  drainage  on  the  north  side  of 
Gauley  River.  As  yet  exploration  has  not  been  sufficiently  extensive 
to  demonstrate  whether  they  are  workable  or  not  in  that  area.  Such 
data  as  are  at  hand,  taken  in  connection  with  the  observed  thinning 
toward  Ganley  River,  both  in  this  quadrangle  and  along  New  River, 
suggest  very  strongly  that  the  New  River  coals  can  not  be  depended 
upon  to  yield  commercial  coal  north  of  Ganley  River. 
Kanavjha  coals. — In  the  region  of  Kanawha  River  at  least  seven 
workable  coals  have  been  found  below  the  black  flint.  Much  question 
still  exists  as  to  the  correlation  of  these  coals  from  point  to  point 
along  the  river,  and  it  has  been  thought  that  probably  coals  of  appar- 
ently the  same  horizons  when  carefully  traced  will  prove  to  be  at 
slightly  different  horizons  and  that  probably  workable  coal  will  be 
found  in  this  eastward  extension  of  the  Kanawha  River  field  at  as 
many  horizons  as  on  Kanawha  River.  At  the  present  time  explora- 
tion and  development  have  been  confined  almost  entirely  to  three 
coals  in  the  lower  part  of  the  formation.  These  three  coals  may 
correspond  with  the  No.  1  Gas,  or  Eagle,  coal,  the  No.  2  Gas,  or 
Ansted,  coal,  and  the  Cedar  Grove  coal,  though  such  correspond- 
ence can  not  be  asserted.  The  upper  part  of  the  Kanawha  for- 
mation outcrops  in  portions  of  the  hills  but  little  inhabited,  and 
exploration  in  that  part  of  the  field  has  been  deterred  in  part  by  the 
presence  of  a  thick  coal  a  short  distance  above  in  the  Charleston  sand- 
stone. Of  the  three  coals  mentioned,  the  lowest  one  is  being  mined 
for  neighborhood  use  between  Keslers  Cross  Lanes  and  Summersville 
and  near  the  head  of  Birch  River.  It  appears  to  be  a  rich,  bright 
coal,  but  of  very  variable  thickness.  When  it  shows  partings  these 
are  usually  of  clay.  It  will  probably  yield  more  or  less  workable  coal 
in  the  quadrangle.  The  next  coal  above,  thought  to  correlate  with 
the  Ansted  coal  at  Ansted,  averages  about  4  feet  in  thickness.     While
