  have 
  attained 
  their 
  greatest 
  development. 
  In 
  the 
  

   Catskill 
  mountains 
  these 
  rocks 
  are 
  still 
  practically 
  horizontal, 
  as 
  

   originally 
  deposited, 
  and 
  in 
  places 
  several 
  thousand 
  feet 
  in 
  thick- 
  

   ness. 
  Limestones 
  and 
  other 
  hard 
  rocks, 
  underlaid 
  by 
  shales 
  and 
  

   soft 
  formations, 
  are 
  found 
  beneath 
  the 
  sandstones 
  in 
  a 
  lower 
  

   stratigraphic 
  horizon.

  In 
  view 
  of 
  the 
  vast 
  increase 
  of 
  population 
  in 
  New 
  York 
  State 
  

   for 
  the 
  past 
  one 
  hundred 
  years 
  the 
  writer 
  considers 
  that 
  the 
  time 
  

   has 
  arrived 
  when 
  the 
  State 
  should 
  make 
  provision 
  for 
  retaining 
  

   a 
  portion 
  of 
  the 
  headwaters 
  of 
  the 
  streams 
  issuing 
  from 
  these 
  

   several 
  elevated 
  region® 
  as 
  a 
  future 
  water 
  supply 
  for 
  the 
  inhab- 
  

   itants. 
  

  

  The 
  population 
  of 
  New 
  York 
  in 
  1800 
  was 
  589,051. 
  In 
  1900— 
  

   one 
  hundred 
  years 
  later 
  — 
  it 
  was 
  7,268,894. 
  In 
  the 
  year 
  2000 
  — 
  

   another 
  one 
  hundred 
  years 
  — 
  it 
  is 
  perhaps 
  difficult 
  to 
  predict 
  what 
  

   it 
  will 
  be, 
  but 
  if 
  with 
  the 
  data 
  from 
  1790 
  to 
  1900, 
  inclusive, 
  we 
  

   plot 
  a 
  population 
  curve, 
  a 
  reasonable 
  estimate 
  of 
  the 
  population 
  

   in 
  the 
  year 
  2000 
  is 
  found 
  to 
  be 
  20,000,000 
  — 
  it 
  may 
  be 
  one 
  or 
  two 
  

   million 
  more 
  than 
  this, 
  or 
  one 
  or 
  two 
  mlillion 
  less, 
  but 
  for 
  a 
  

   period 
  nearly 
  one 
  hundred 
  years 
  in 
  advance, 
  20,000,000 
  is 
  a 
  con- 
  

   servative 
  estimate.

  Of 
  the 
  present 
  population 
  of 
  7,268,894, 
  in 
  1900 
  6,206,657 
  were 
  

   on 
  an 
  area 
  of 
  approximately 
  23,440 
  square 
  miles, 
  or 
  a 
  trifle 
  less 
  

   than 
  one-half 
  the 
  land 
  area 
  of 
  the 
  State, 
  which 
  is, 
  according 
  to 
  

   the 
  twelfth

  47,620
