  2) 
  A 
  larger 
  proportion 
  of 
  the 
  ultimate 
  first 
  cost 
  may 
  be 
  de- 
  

   ferred 
  by 
  the 
  Poughkeepsie 
  plan 
  than 
  by 
  either 
  the 
  Catskill 
  or 
  

   Adirondack 
  plan. 
  

  

  3) 
  The 
  time 
  necessary 
  for 
  construction 
  is 
  also 
  less. 
  Water 
  

   from 
  the 
  Hudson 
  at 
  Poughkeepsie 
  can 
  be 
  delivered 
  in 
  six 
  years 
  ; 
  

   from 
  the 
  Catskills, 
  in 
  seven 
  years, 
  and 
  from 
  the 
  Adirondacks, 
  

   in 
  seven 
  and 
  one-half 
  years. 
  

  

  4) 
  The 
  Adirondack's 
  and 
  the 
  Hudson 
  together 
  would 
  furnish 
  

   1,500,000,000 
  gallons 
  per 
  day, 
  while 
  the 
  Catskill 
  catchment 
  can 
  

   not 
  furnish 
  more 
  than 
  260,000,000 
  gallons, 
  or, 
  with 
  Schoharie 
  

   creek, 
  460,000,000 
  gallons 
  per 
  day. 
  

  

  5) 
  The 
  length 
  of 
  the 
  aqueduct 
  would 
  be 
  less 
  from 
  Pough- 
  

   keepsie 
  than 
  from 
  either 
  the 
  Adirondacks 
  or 
  the 
  Catskills. 
  

   From 
  Poughkeepsie 
  a 
  high 
  level 
  aqueduct 
  would 
  be 
  60 
  miles 
  in 
  

   length; 
  from 
  the 
  Adirondacks, 
  203 
  miles, 
  and 
  from 
  the 
  Catskills, 
  

   100 
  miles. 
  

  

  The 
  lesser 
  length 
  of 
  the 
  Poughkeepsie 
  aqueduct 
  is 
  not 
  only 
  

   an 
  important 
  element 
  in 
  construction, 
  but 
  is 
  quite 
  as 
  important 
  

   in 
  maintenance 
  and 
  protection. 
  

  

  Water 
  taken 
  at 
  Poughkeepsie 
  would 
  require 
  filtration, 
  and 
  

   in 
  the 
  modern 
  view 
  it 
  would 
  also 
  require 
  filtration 
  from 
  the 
  

   Adirondacks, 
  although 
  it 
  may 
  be 
  very 
  appropriately 
  questioned 
  

   whether 
  a 
  water 
  supply 
  from 
  a 
  seriously 
  sewage-polluted 
  stream 
  

   is 
  desirable 
  so 
  long 
  as 
  unpolluted 
  sources 
  are 
  available 
  without 
  

   increasing 
  the 
  cost 
  per 
  unit.

  Reservoir 
  on 
  WallMll 
  river. 
  Among 
  other 
  interesting 
  reser- 
  

   voirs 
  which 
  have 
  been 
  recently 
  proposed 
  for 
  the 
  supply 
  of 
  Greater 
  

   New 
  York, 
  that 
  on 
  the 
  Wallkill 
  river 
  may 
  be 
  described 
  in 
  detail. 
  

   This 
  reservoir 
  was 
  reported 
  upon 
  by 
  James 
  H. 
  Fuertes, 
  whose 
  

   report 
  appears 
  in 
  the 
  Report 
  of 
  the 
  Merchants' 
  Association 
  of 
  

   New 
  York, 
  made 
  in 
  1900. 
  

  

  Wallkill 
  river 
  rises 
  in 
  northern 
  New 
  Jersey 
  2 
  a 
  few 
  miles 
  south 
  

   of 
  Sparta. 
  It 
  flows 
  in 
  a 
  northeasterly 
  direction, 
  entering 
  the 
  

   State 
  of 
  New 
  York 
  about 
  half 
  way 
  between 
  Liberty 
  Corner 
  and 
  

   Unionville. 
  It 
  then' 
  flows 
  through 
  Orange 
  and 
  Ulster 
  counties, 
  

   joining 
  Rondout 
  creek, 
  which 
  empties 
  into 
  the 
  Hudson 
  river 
  at 
  

   Kingston.
