  building 
  stone, 
  the 
  decrease 
  being 
  distributed 
  over 
  all 
  the 
  differ- 
  

   ent 
  districts. 
  There 
  was 
  little 
  change 
  in 
  the 
  values 
  of 
  the 
  other 
  

   materials 
  from 
  those 
  reported 
  in 
  1906. 
  The 
  combined 
  total 
  of 
  

   sandstone 
  quarried 
  on 
  the 
  other 
  hand 
  showed 
  an 
  increase. 
  

  

  The 
  production 
  of 
  bluestone 
  by 
  districts 
  was 
  as 
  follows, 
  the 
  

   figures 
  for 
  1906 
  being 
  in 
  parentheses: 
  Hudson 
  river 
  $293,895 
  

   ($306,005) 
  ; 
  Delaware 
  river 
  $703,428 
  ($685,716) 
  ; 
  Wyoming 
  county 
  

   $196,769 
  ($235,813) 
  ; 
  Chenango 
  county 
  $106,703 
  ($130,239) 
  ; 
  other 
  

   districts 
  $15,132 
  ($20,000). 
  In 
  the 
  Hudson 
  river 
  district 
  of 
  

   Albany, 
  Greene 
  and 
  Ulster 
  counties, 
  about 
  65 
  per 
  cent 
  of 
  the 
  

   output 
  in 
  1907 
  was 
  sold 
  as 
  flagstone 
  and 
  curbstone 
  and 
  about 
  21 
  

   per 
  cent 
  as 
  building 
  stone. 
  In 
  the 
  Delaware 
  river 
  district 
  in- 
  

   cluding 
  Sullivan, 
  Delaware 
  and 
  Broome 
  counties, 
  the 
  value 
  of 
  

   the 
  flagstone 
  and 
  curbstone 
  sold 
  amounted 
  to 
  about 
  88 
  per 
  cent 
  

   and 
  the 
  building 
  stone 
  to 
  11 
  per 
  cent. 
  In 
  Chenango 
  county 
  

   about 
  60 
  per 
  cent 
  of 
  the 
  entire 
  product 
  was 
  marketed 
  as 
  build- 
  

   ing 
  stone, 
  while 
  in 
  Wyoming 
  county 
  practically 
  the 
  whole 
  output 
  

   consisted 
  of 
  that 
  material. 
  

  

  The 
  production 
  of 
  Medina 
  sandstone 
  in 
  Orleans 
  county 
  last 
  

   year 
  was 
  valued 
  at 
  $542,218, 
  as 
  compared 
  with 
  $484,938, 
  the 
  value 
  

   of 
  the 
  output 
  in 
  1906. 
  This 
  stone 
  has 
  come 
  into 
  wide 
  use 
  for 
  

   street 
  work 
  owing 
  to 
  its 
  durability 
  and 
  even 
  wear, 
  and 
  is 
  also 
  

   an 
  attractive 
  building 
  material. 
  The 
  quarries 
  at 
  Albion, 
  Medina, 
  

   Holley, 
  etc., 
  are 
  large 
  and 
  well 
  equipped. 
  

  

  Trap 
  

  

  The 
  term 
  trap 
  is 
  commonly 
  applied 
  to 
  the 
  dark 
  fine 
  grained 
  

   igneous 
  rocks 
  occurring 
  as 
  dikes 
  or 
  sheetlike 
  intrusions. 
  The 
  

   variety 
  known 
  as 
  diabase, 
  composed 
  essentially 
  of 
  plagioclase 
  

   feldspar 
  and 
  pyroxene 
  in 
  small 
  interlocking 
  crystals, 
  is 
  the 
  most 
  

   common 
  in 
  New 
  York 
  State. 
  The 
  dikes 
  are 
  well 
  distributed 
  

   throughout 
  the 
  eastern 
  Adirondacks, 
  particularly 
  in 
  Clinton 
  and 
  

   Essex 
  counties, 
  but 
  they 
  are 
  usually 
  too 
  small 
  to 
  be 
  workable. 
  

   The 
  dikes 
  near 
  Greenfield, 
  Saratoga 
  co., 
  and 
  at 
  Little 
  Falls, 
  Her- 
  

   kimer 
  co., 
  are 
  exceptional 
  in 
  size 
  for 
  that 
  region, 
  having 
  a 
  thick- 
  

   ness 
  of 
  200 
  feet 
  or 
  more. 
  By 
  far 
  the 
  largest 
  occurrence 
  in 
  the 
  

   State 
  is 
  that 
  on 
  the 
  west 
  side 
  of 
  the 
  Hudson 
  river, 
  south 
  of 
  

   Haverstraw, 
  which 
  forms 
  the 
  remarkable 
  scenic 
  feature 
  known 
  

   as 
  the 
  Palisades. 
  The 
  southern 
  end 
  of 
  this 
  intrusion 
  is 
  found 
  on 
  

   Staten 
  Island 
  where 
  it 
  extends 
  southwest 
  from 
  Port 
  Richmond. 
  

  

  The 
  principal 
  use 
  of 
  trap 
  is 
  for 
  crushed 
  stone 
  for 
  roadmaking
