  We 
  also 
  have 
  five 
  sheets 
  either 
  in 
  or 
  in 
  the 
  vicinity 
  of 
  the 
  Hudson 
  

   river 
  catchment 
  area, 
  namely, 
  Fort 
  Ann, 
  North 
  Creek, 
  Glens 
  Falls, 
  

   Cambridge 
  and 
  Schuylerville. 
  The 
  totals 
  for 
  these 
  five 
  sheets 
  are 
  

   virgin 
  forest, 
  0; 
  culled 
  area, 
  311.45 
  square 
  miles; 
  cleared 
  area, 
  

   749.0 
  square 
  miles; 
  water 
  area, 
  32.25 
  square 
  miles; 
  total 
  area 
  of 
  

   the 
  five 
  sheets, 
  1087.4 
  square 
  miles. 
  In 
  a 
  portion 
  of 
  the 
  region 
  

   covered 
  by 
  these 
  sheets 
  the 
  tendency 
  is 
  for 
  many 
  of 
  the 
  hard, 
  stony 
  

   hill 
  farms 
  to 
  revert 
  to 
  forest 
  conditions. 
  We 
  may 
  assume, 
  there- 
  

   fore, 
  that 
  throughout 
  the 
  Adirondack 
  region 
  the 
  forest 
  area 
  is 
  

   slowly 
  increasing. 
  

  

  As 
  a 
  summation 
  of 
  this 
  discussion 
  it 
  may 
  be 
  concluded, 
  taking 
  

   into 
  account 
  the 
  erection 
  by 
  the 
  State 
  of 
  New 
  York 
  of 
  the 
  Adiron- 
  

   dack 
  park, 
  as 
  well 
  as 
  the 
  tendency 
  to 
  abandon 
  stony 
  farms, 
  that 
  on 
  

   the 
  whole 
  the 
  conditions 
  governing 
  the 
  runoff 
  of 
  streams 
  on 
  Black 
  

   river 
  are 
  improving. 
  The 
  same 
  thing 
  is 
  true 
  of 
  the 
  Hudson 
  and 
  

   Mohawk 
  rivers 
  or 
  of 
  any 
  other 
  stream 
  issuing 
  from 
  the 
  State 
  

   forests. 
  Deductions, 
  therefore, 
  based 
  on 
  what 
  has 
  happened 
  in 
  

   the 
  past 
  may 
  be 
  expected 
  to 
  be 
  realized 
  in 
  the 
  future. 
  

  

  The 
  main 
  water 
  power 
  developments 
  of 
  New 
  York. 
  In 
  the 
  State 
  

   of 
  New 
  York 
  there 
  are 
  seven 
  large 
  towns, 
  at 
  all 
  of 
  which 
  the 
  

   original 
  basis 
  of 
  the 
  development 
  was 
  water 
  power, 
  namely, 
  Lock- 
  

   port, 
  Rochester, 
  Oswego, 
  Watertown, 
  Little 
  Falls, 
  Glens 
  Falls 
  

   and 
  Cohoes. 
  The 
  recent 
  development 
  of 
  the 
  city 
  of 
  Niagara 
  Falls 
  

   is 
  also 
  due 
  purely 
  to 
  the 
  water 
  power 
  of 
  Niagara 
  river, 
  but 
  this 
  

   was 
  not 
  the 
  original 
  basis 
  of 
  growth. 
  The 
  attraction 
  of 
  the 
  falls 
  

   as 
  a 
  great 
  natural 
  curiosity 
  gave 
  this 
  place 
  its 
  original 
  impulse. 
  

   There 
  are 
  also 
  a 
  number 
  of 
  smaller 
  places 
  in 
  the 
  State 
  where 
  

   water 
  power 
  has 
  developed 
  towns, 
  but 
  the 
  foregoing 
  are 
  the 
  larger 
  

   ones. 
  Moreover, 
  so 
  strong 
  has 
  been 
  the 
  impulse 
  of 
  the 
  water 
  

   power 
  that 
  several 
  of 
  these 
  towns 
  have 
  developed 
  at 
  locations 
  

   where 
  there 
  were 
  serious 
  adverse 
  conditions. 
  At 
  Lockport 
  there 
  

   is 
  no 
  water 
  supply 
  within 
  reasonable 
  distance. 
  Even 
  in 
  1904, 
  

   aside 
  from 
  a 
  few 
  polluted 
  wells, 
  the 
  water 
  supply 
  for 
  the 
  town 
  

   is 
  still 
  taken 
  from 
  Erie 
  canal, 
  which 
  receives 
  the 
  sewage 
  of 
  over
