parts  of  Bennett  Fork  tends  to  increase  to  4  feet  or  more.  A  single 
section  will  give  a  good  idea  of  how  it  averages  at  most  of  the  mines 
working  it.

This  coal  is  worked  at  the  Mingo  Nos.  1  and  2  mines,  the  Fork 
Ridge,  the  Reliance,  B^son  Mountain,  and  Ralston  No.  1  mines. 
From  its  low  position  in  the  mountain  it  occupies  a  much  larger  area 
than  any  of  the  higher  coals-,  but  probably  is  not  workable  over  so 
large  an  area  as  some  of  the  others. 
Chenoa  coal.—  At  Chenoa,  on  Big  Clear  Creek,. a  cannel  coal  has  been 
extensively  mined.  It  is  estimated  to  lie  more  than  500  feet  below 
the  Sandstone  Parting  coal.  Its  presence  led  to  the  building  of  the 
railroad  up  Big  Clear  Creek  from  Pineville.  Mining  has  shown  it  to 
occur  in  a  very  limited  basin,  as  is  usual  with  cannel  coals,  not  over  600 
feet  wide,  though  it  has  been  followed  4,000  feet  into  the  mountain. 
It  showed  the  following  section:

On  account  of  the  change  in  the  thickness  of  the  strata  in  going 
from  Big  Clear  Creek  to  Bennett  Fork  its  exact  equivalent  on  the  lat- 
ter stream  is  uncertain. 
Bennett  Fork  coal. — This  is  the  coal  at  the  Bennett  Fork  mine  and 
other  openings  near  the  mouth  of  Bennett  Fork.  It  is  below  drain- 
age over  most  of  this  area,  so  that  little  is  known  of  its  extent  or 
workability .
