  It

  The 
  limestone 
  areas 
  of 
  this 
  county 
  though 
  not 
  extensive 
  in- 
  

   clude 
  some 
  of 
  the 
  purest 
  limestones 
  found 
  in 
  the 
  state. 
  One 
  

   narrow 
  belt 
  extends 
  from 
  Middle 
  Falls 
  to 
  North 
  Argyle, 
  a 
  second 
  

   begins 
  at 
  Adamsville 
  and 
  extends 
  northward 
  past 
  the 
  eastern 
  

   edge 
  of 
  Fort 
  Ann 
  and 
  Whitehall 
  to 
  the 
  Vermont 
  boundary. 
  A 
  

   third 
  area 
  lies 
  on 
  the 
  boundary 
  between 
  New 
  York 
  and 
  Vermont 
  

   and 
  along 
  the 
  Rutland

  The 
  rock 
  has 
  

   been 
  extensively 
  quarried 
  at 
  Smiths 
  Basin 
  and 
  west 
  of 
  Fair- 
  

   haven. 
  

  

  At 
  Smiths 
  Basin 
  the 
  Keenan 
  lime 
  co. 
  has 
  several 
  quarries 
  

   in 
  the 
  ridge 
  to 
  the 
  east 
  of 
  the 
  railroad. 
  The 
  rock 
  is 
  mostly 
  

   dark 
  gray 
  to 
  bluish 
  black, 
  fine 
  grained 
  and 
  moderately 
  hard. 
  Its 
  

   massive 
  character 
  has 
  been 
  somewhat 
  destroyed 
  in 
  places 
  by 
  the 
  

   shearing 
  and 
  folding 
  to 
  which 
  the 
  rock 
  has 
  been 
  subjected. 
  The 
  

   upper 
  beds 
  are 
  shaly 
  and 
  siliceous 
  but 
  the 
  lower 
  ones 
  are 
  very
