  only 
  general 
  statements 
  can 
  be 
  made 
  for 
  lack 
  of 
  definite 
  data. 
  

   Probably 
  enough 
  storage 
  can 
  be 
  made 
  here 
  to 
  give 
  a 
  final 
  storage 
  

   on 
  Hudson 
  and 
  Mohawk 
  rivers 
  of 
  about 
  75,000,000,000 
  cubic 
  feet: 
  

  

  The 
  foregoing 
  estimates 
  of 
  cost

  take 
  into 
  account 
  present 
  

   labor 
  conditions, 
  etc. 
  in 
  New 
  York 
  State. 
  The 
  approximate 
  cost 
  

   per 
  million 
  cubic 
  feet 
  of 
  storage 
  is 
  found 
  to 
  be 
  $101.

  have 
  been 
  so 
  fully 
  set

   as 
  to

  Leaving 
  for 
  the 
  present 
  the 
  possible 
  storage 
  of 
  the 
  upper 
  Mohawk 
  

   river 
  out 
  of 
  account, 
  and 
  basing 
  conclusions 
  on 
  56,728,000,000 
  

   cubic 
  feet 
  storage 
  on 
  the 
  upper 
  Hudson, 
  we 
  may 
  say, 
  taking 
  into 
  

   account 
  low-water 
  flow 
  of 
  the 
  Mohawk 
  river 
  and 
  other 
  tributaries 
  

   of 
  the 
  Hudson 
  river 
  below 
  Mechanicville, 
  that 
  the 
  fresh 
  water 
  

   inflow 
  of 
  the 
  lower 
  Hudson 
  river 
  may 
  be 
  kept 
  up 
  to 
  over 
  6000 
  cubic 
  

   feet 
  per 
  second. 
  At 
  present 
  it 
  is 
  occasionally 
  somewhat 
  less 
  than 
  

   2000 
  cubic 
  feet 
  per 
  second. 
  The

  of

  Power 
  Development 
  at 
  Niagara 
  Falls 
  

   The 
  possibility 
  of 
  water-power 
  development 
  at 
  Niagara 
  Falls 
  

   has 
  attracted 
  attention 
  for 
  many 
  years, 
  the 
  first 
  utilization 
  there 
  

   having 
  been 
  made 
  in 
  1725, 
  when 
  the 
  French 
  erected 
  a 
  sawmill 
  

   near 
  the 
  point 
  where 
  the 
  Pittsburgh 
  Reduction 
  Company's 
  upper 
  

   works 
  now 
  stand 
  for 
  the 
  purpose 
  of 
  supplying 
  lumber 
  for 
  Fort 
  

   Niagara. 
  Between 
  1725 
  and 
  the 
  early 
  years 
  of 
  the 
  present 
  cen- 
  

   tury 
  little 
  is 
  known 
  of 
  the 
  use 
  made 
  of 
  Niagara 
  Falls 
  power 
  

   further 
  than 
  that 
  sawmills 
  were 
  in 
  operation 
  there 
  during 
  the 
  

   whole 
  period. 
  In 
  1805, 
  however, 
  Augustus 
  Porter 
  built 
  a 
  sawmill 
  

   on 
  the 
  rapids, 
  and 
  in 
  1807 
  Porter 
  & 
  Barton 
  erected 
  a 
  gristmill. 
  

   In 
  1817 
  John 
  Witmer 
  built 
  another 
  sawmill 
  at 
  Gill 
  creek, 
  and
