  as 
  demand 
  for 
  stone 
  develops. 
  It 
  is 
  used 
  both 
  for 
  structural 
  pur- 
  

   poses 
  and 
  for 
  road 
  metal. 
  

  

  In 
  the 
  quarry 
  near 
  Wilton 
  a 
  twelve-foot 
  thickness 
  of 
  similar 
  

   beds 
  is 
  shown, 
  also 
  with 
  cherts 
  and 
  drusy 
  cavities 
  containing 
  quartz 
  

   crystals. 
  This 
  quarry 
  was 
  opened 
  chiefly 
  for 
  road 
  metal 
  purposes, 
  

   and 
  its 
  product 
  has 
  been 
  much 
  used 
  on 
  the 
  State 
  roads 
  of 
  the 
  

   vicinity. 
  Some 
  misapprehension 
  as 
  to 
  the 
  true 
  nature 
  of 
  the 
  rock 
  

   exists 
  in 
  the 
  minds 
  of 
  some 
  people, 
  as 
  we 
  frequently 
  heard 
  it 
  re- 
  

   ferred 
  to 
  as 
  a 
  trap 
  quarry, 
  perhaps 
  with 
  the 
  idea 
  that 
  any 
  rock 
  

   used 
  on 
  the 
  roads 
  must 
  of 
  necessity 
  be 
  trap. 
  The 
  material 
  should 
  

   make 
  an 
  acceptable 
  road 
  metal, 
  though 
  by 
  no 
  means 
  so 
  good 
  as 
  

   good 
  trap. 
  

  

  Between 
  3 
  and 
  4 
  miles 
  due 
  west 
  of 
  Saratoga 
  four 
  quarries 
  have 
  

   been 
  opened 
  in 
  the 
  dolomite, 
  on 
  the 
  west 
  side 
  of 
  the 
  Highland 
  

   Park 
  fault. 
  The 
  horizon 
  in 
  the 
  formation 
  is 
  somewhat 
  uncertain, 
  

   but 
  is 
  judged 
  to 
  be 
  near 
  the 
  summit, 
  since 
  Amsterdam 
  limestone 
  

   is 
  the 
  surface 
  rock 
  a 
  short 
  distance 
  away 
  to 
  the 
  south. 
  The 
  beds 
  

   are 
  massive 
  for 
  the 
  most 
  part, 
  and 
  consist 
  of 
  alternating 
  courses 
  

   of 
  dark 
  colored, 
  fine 
  grained 
  stone, 
  and 
  lighter 
  beds 
  of 
  coarser 
  

   grain. 
  At 
  the 
  time 
  of 
  our 
  visit 
  none 
  of 
  these 
  quarries 
  were 
  being 
  

   worked 
  and 
  we 
  could 
  obtain 
  but 
  little 
  information 
  regarding 
  

   them. 
  One 
  of 
  them 
  is 
  quite 
  extensive 
  and 
  the 
  stone 
  is 
  likely 
  used 
  

   both 
  for 
  structural 
  purposes 
  and 
  for 
  crushed 
  stone. 
  

  

  Limestone. 
  Three 
  of 
  the 
  formations 
  of 
  the 
  district 
  have 
  been 
  

   quarried 
  for 
  limestone, 
  the 
  Hoyt 
  and 
  Amsterdam 
  limestones 
  of 
  

   the 
  western 
  basin 
  and 
  the 
  Bald 
  Mountain 
  limestone 
  of 
  the 
  eastern 
  

   basin. 
  

  

  Two 
  quite 
  large 
  quarries 
  have 
  been 
  worked 
  in 
  the 
  Hoyt 
  lime- 
  

   stone, 
  the 
  Railroad 
  quarry 
  and 
  the 
  Hoyt 
  quarry, 
  the 
  former 
  1 
  

   mile 
  north 
  and 
  the 
  latter 
  3 
  miles 
  west 
  of 
  Saratoga 
  Springs 
  (plates 
  

   5 
  and 
  2). 
  Neither 
  has 
  been 
  worked 
  for 
  some 
  years, 
  and 
  the 
  

   earlier 
  working 
  was 
  to 
  supply 
  lime 
  chiefly 
  for 
  local 
  use. 
  The 
  

   quarries 
  are 
  thus 
  examples 
  of 
  what 
  has 
  happened 
  on 
  a 
  large 
  scale 
  

   all 
  over 
  northern 
  New 
  York, 
  the 
  passing 
  of 
  local 
  limekilns 
  and 
  

   the 
  concentration 
  of 
  the 
  lime 
  industry 
  at 
  a 
  few 
  localities 
  deter 
  

   mined 
  by 
  favorable 
  location 
  and 
  quantity 
  and 
  purity 
  of 
  the 
  

   limestone. 
  

  

  The 
  Amsterdam 
  limestone 
  has 
  been 
  quarried 
  at 
  Rowlands 
  Mil 
  1 
  

   and 
  at 
  Rock 
  City 
  Falls. 
  It 
  was 
  burned 
  for 
  lime 
  to 
  some 
  extent 
  

   and 
  also 
  used 
  for 
  structural 
  purposes 
  and 
  on 
  the 
  roads. 
  At 
  present 
  

   it 
  is 
  being 
  extensively 
  quarried 
  at 
  Rock 
  City 
  Falls 
  to 
  furnish 
  

   crushed 
  stone 
  for 
  concrete.
