  collected 
  at 
  this 
  point 
  have 
  not 
  

   yet 
  been 
  received, 
  but 
  it 
  is 
  doubted 
  if 
  this 
  bed 
  can 
  ever 
  be 
  of 
  

   more 
  than 
  local 
  importance 
  and 
  that 
  only 
  after 
  the 
  great 
  amount 
  

   of 
  good 
  pine 
  wood 
  which 
  covers 
  the' 
  country 
  is

  — 
  This 
  locality 
  is 
  interesting 
  because 
  the 
  

   lignite 
  is 
  here 
  of 
  sufficiently 
  good 
  quality 
  to 
  have 
  been 
  used 
  as 
  

   fuel
