  The 
  Bald 
  Mountain 
  limestone 
  has 
  been 
  quarried 
  at 
  Bald 
  moun- 
  

   tain 
  and 
  at 
  Middle 
  Falls. 
  On 
  the 
  west 
  face 
  of 
  Bald 
  mountain 
  the 
  

   steep 
  western 
  limb 
  of 
  the 
  overturned 
  anticline 
  which 
  this 
  limestone 
  

   forms 
  there, 
  produces 
  a 
  limestone 
  face 
  100 
  feet 
  high, 
  which 
  was 
  

   well 
  adapted 
  to 
  easy 
  and 
  rapid 
  quarrying. 
  The 
  greater 
  part 
  of 
  the 
  

   material 
  was 
  burned 
  for 
  lime 
  on 
  the 
  spot. 
  

  

  Ruedemann 
  furnishes 
  the 
  following 
  notes 
  on 
  quarries 
  in 
  this 
  

   limestone 
  noted 
  by 
  him 
  : 
  

  

  The 
  quarry 
  at 
  Middle 
  Falls, 
  which 
  has 
  furnished 
  the 
  fauna, 
  is 
  

   a 
  small 
  one, 
  showing 
  some 
  25 
  feet 
  of 
  heavy 
  bedded 
  limestone 
  quite 
  

   like 
  that 
  at 
  Bald 
  mountain. 
  The 
  beds 
  are 
  nearly 
  horizontal. 
  The 
  

   quarry 
  was 
  long 
  ago 
  abandoned, 
  but 
  the 
  material 
  was 
  probably 
  

   used 
  exclusively 
  for 
  lime. 
  

  

  A 
  half 
  mile 
  west 
  of 
  Middle 
  Falls, 
  on 
  the 
  west 
  bank 
  of 
  Batten 
  

   kill, 
  at 
  the 
  bend, 
  is 
  a 
  much 
  larger 
  quarry, 
  exposing 
  a 
  thickness 
  

   of 
  50 
  feet 
  of 
  beds, 
  20 
  feet 
  of 
  dolomite 
  beneath, 
  and 
  30 
  feet 
  of 
  

   limestone 
  above. 
  The 
  beds 
  are 
  here 
  nearly 
  vertical, 
  with 
  steep 
  dip 
  

   to 
  west 
  and 
  northeast 
  strike. 
  One 
  and 
  one-fourth 
  miles 
  farther 
  

   south 
  is 
  another 
  large 
  quarry, 
  and 
  a 
  smaller 
  one 
  yet 
  farther 
  south. 
  

   The 
  bulk 
  of 
  the 
  material 
  quarried 
  was 
  burned 
  for 
  lime, 
  but 
  the 
  less 
  

   massive 
  beds 
  were 
  also 
  utilized 
  in 
  structural 
  work. 
  In 
  the 
  report 
  

   on 
  the 
  first 
  district 
  Mather 
  speaks 
  of 
  the 
  quarries 
  here, 
  which 
  were 
  

   in 
  active 
  operation 
  at 
  that 
  time.

  It 
  is 
  some 
  40 
  years 
  since 
  this 
  industry 
  lapsed. 
  There 
  is 
  a 
  large 
  

   quantity 
  of 
  excellent 
  limestone 
  along 
  this 
  belt, 
  and 
  when 
  the 
  

   available 
  material 
  at 
  Glens 
  Falls 
  approaches 
  exhaustion, 
  a 
  revival 
  

   of 
  operations 
  here 
  is 
  not 
  unlikely. 
  

  

  Normanskill 
  grits. 
  There 
  are 
  several 
  abandoned 
  quarries 
  in 
  the 
  

   grit 
  bands 
  of 
  the 
  Normanskill 
  shales 
  in 
  the 
  vicinity 
  of 
  Quaker 
  

   Springs. 
  These 
  durable 
  sandstones 
  had 
  a 
  wide 
  use 
  all 
  over 
  the 
  

   region 
  for 
  structural 
  purposes, 
  but 
  the 
  quarries 
  have 
  been 
  idle 
  for 
  

   some 
  20 
  years. 
  

  

  MINERAL 
  WATERS 
  

   The 
  district 
  centering 
  at 
  Saratoga 
  Springs 
  has 
  long 
  been 
  famous 
  

   for 
  its 
  mineral 
  waters, 
  and 
  especially 
  for 
  its 
  very 
  distinctive, 
  highly 
  

   carbonated, 
  saline 
  waters. 
  There 
  are 
  in 
  addition 
  numerous 
  sul- 
  

   phur 
  springs 
  in 
  the 
  region, 
  which 
  would 
  probably 
  have 
  a 
  wider 
  

   repute 
  had 
  the 
  other 
  waters 
  not 
  been 
  also 
  present. 
  

  

  The 
  sulphur 
  waters 
  of 
  the 
  region 
  all 
  rise 
  from 
  the 
  black 
  shales 
  

   (Canajoharie, 
  Normanskill, 
  Snake 
  Hill), 
  and 
  taste 
  strongly 
  of 
  sul- 
  

   phuretted 
  hydrogen, 
  derived 
  no 
  doubt 
  from 
  the 
  decomposition 
  of
