  Limestone 
  

  

  Owing 
  to 
  the 
  many 
  purposes 
  for 
  which 
  Hmestone 
  seems 
  particu- 
  

   larly 
  adapted, 
  and 
  because 
  of 
  its 
  wide 
  distribution 
  in 
  the 
  State, 
  it 
  

   holds 
  first 
  place 
  in 
  importance 
  among 
  the 
  quarry 
  products. 
  As 
  

   crushed 
  stone 
  for 
  road 
  building 
  and 
  concrete 
  work, 
  it 
  has 
  attained 
  

   a 
  wide 
  use; 
  as 
  a 
  building 
  stone, 
  its 
  ease 
  of 
  dressing 
  and 
  quarrying 
  

   and 
  its 
  durability 
  favor 
  it 
  ; 
  large 
  quantities 
  are 
  burned 
  mto 
  lime 
  ; 
  

   a 
  large 
  amount 
  is 
  annually 
  consumed 
  as 
  a 
  flux, 
  and 
  it 
  has 
  as 
  well 
  

   many 
  minor 
  uses. 
  

  

  With 
  the 
  exception 
  of 
  some 
  crystalline, 
  metamorphic 
  limestone 
  

   that 
  is 
  quarried 
  and 
  sold 
  as 
  flux 
  or 
  burned 
  into 
  lime, 
  the 
  stone 
  

   classed 
  under 
  this 
  head 
  is 
  all 
  of 
  a 
  massive 
  noncrystalline 
  character. 
  

   The 
  '.limestones 
  occur 
  in 
  formations 
  from 
  the 
  Cambric 
  to 
  the 
  

   Devonic 
  systems, 
  the 
  chief 
  limestones 
  used 
  being 
  the 
  Beekman- 
  

   tovvn, 
  Chazy, 
  Trenton, 
  Lockport 
  dolomite, 
  Cobleskill, 
  Onondaga 
  and 
  

   Tully. 
  They 
  vary 
  in 
  color 
  from 
  gray 
  and 
  brown 
  to 
  blue 
  or 
  black, 
  

   while 
  the 
  white 
  and 
  lighter 
  colored 
  limestones 
  are 
  rare. 
  In 
  

   chemical 
  composition 
  they 
  vary 
  from 
  almost 
  pure 
  calcium 
  carbonate 
  

   to 
  dolomite 
  and 
  frequently 
  become 
  argillaceous, 
  arenaceous, 
  fer- 
  

   ruginous 
  or 
  silicious. 
  

  

  The 
  total 
  production 
  of 
  limestone 
  in 
  1908 
  exclusive 
  of 
  stone 
  

   used 
  in 
  cement 
  manufacture 
  was 
  valued 
  at 
  $3,119,835, 
  a 
  small 
  de- 
  

   crease 
  over 
  the 
  production 
  of 
  1907, 
  which 
  was 
  S3,i82,z^.7, 
  or 
  about 
  

   2 
  per 
  cent. 
  This 
  decrease 
  seems 
  to 
  be 
  fairly 
  evenly 
  distributed 
  over 
  

   the 
  various 
  uses 
  of 
  the 
  stone 
  and 
  as 
  well 
  over 
  the 
  various 
  counties, 
  

   none 
  of 
  which 
  shows 
  a 
  marked 
  decrease 
  or 
  increase 
  in 
  production 
  

   during 
  the 
  year. 
  The 
  production 
  was 
  distributed 
  among 
  the 
  

   various 
  products 
  as 
  follows: 
  crushed 
  stone 
  $1,647,629; 
  building 
  

   stone 
  $245,655; 
  lime 
  $401,728; 
  furnace 
  flux 
  $230,117; 
  other 
  uses 
  

   $594,706. 
  The 
  lime 
  made 
  by 
  the 
  Solvay 
  Process 
  Co. 
  and 
  by 
  the 
  

   Union 
  Carbide 
  Co. 
  in 
  connection 
  with 
  their 
  products 
  is 
  included 
  

   under 
  " 
  Other 
  uses 
  " 
  in 
  1908 
  while 
  in 
  previous 
  years 
  it 
  appears 
  

   under 
  " 
  Lime."
