﻿HYDROLOGY

  is 
  intended 
  to 
  run 
  to 
  the 
  village 
  of 
  Canton, 
  10% 
  miles 
  from 
  Han- 
  

   nawa 
  Falls, 
  and 
  finally 
  to 
  the 
  city 
  of 
  Ogdensburg, 
  19 
  miles 
  

   farther. 
  

  

  It 
  is 
  also 
  intended 
  to 
  utilize 
  a 
  portion 
  of 
  the 
  power 
  to 
  be 
  de- 
  

   veloped 
  here 
  for 
  grinding 
  wood-pulp, 
  and 
  accordingly 
  a 
  ground 
  

   wood-pulp 
  plant 
  of 
  100 
  tons 
  capacity 
  per 
  day 
  is 
  included. 
  

  

  In 
  the 
  grinder 
  room 
  two 
  pairs 
  of 
  4000-horsepower 
  water-wheels, 
  

   built 
  by 
  the 
  S. 
  Morgan 
  Smith 
  Company, 
  are 
  placed 
  on 
  horizontal 
  

   shafts 
  and 
  supplied 
  with 
  water 
  from 
  two 
  independent 
  10-foot 
  pen- 
  

   stocks, 
  discharging 
  into 
  a 
  common 
  tailrace.

  From 
  the 
  foregoing 
  

   it 
  appears 
  that 
  in 
  1901 
  about 
  9000 
  horsepower 
  is 
  developed 
  at 
  this 
  

   station, 
  although 
  the 
  writer 
  is 
  unable 
  to 
  state 
  whether 
  or 
  not 
  the 
  

   full 
  capacity 
  of 
  the 
  pulp-grinding 
  machinery 
  is 
  utilized. 
  These 
  

   works 
  were 
  designed 
  by 
  W. 
  C. 
  Johnson. 
  

  

  Waterpower 
  of 
  Erie 
  canal 
  

  

  When 
  the 
  Erie 
  canal 
  was 
  first 
  constructed 
  the 
  policy 
  was 
  

   adopted 
  of 
  leasing 
  the 
  so-called 
  surplus 
  water 
  for 
  power 
  pur- 
  

   poses. 
  Under 
  the 
  terms 
  of 
  the 
  act 
  of 
  1825 
  leases 
  were 
  made 
  

   during 
  1826 
  and 
  subsequent 
  years 
  to 
  a 
  number 
  of 
  persons 
  at 
  

   Black 
  Rock, 
  Lockport 
  and 
  other 
  localities. 
  

  

  Power 
  at 
  Black 
  Rock. 
  The 
  granting 
  of 
  these 
  leases 
  and 
  the 
  

   resultant 
  development 
  of 
  large 
  manufacturing 
  interests 
  at 
  several 
  

   points 
  have 
  raised 
  certain 
  economic 
  questions 
  which 
  will 
  now 
  be 
  

   briefly 
  discussed. 
  The 
  waterpower 
  at 
  Black 
  Rock, 
  for 
  whicL 
  

   several 
  leases 
  were 
  granted, 
  will 
  be 
  first 
  mentioned. 
  This 
  power 
  

   is 
  created 
  by 
  the 
  difference 
  in 
  level 
  between 
  the 
  water 
  in 
  the 
  Erie 
  

   canal 
  and 
  the 
  Black 
  Rock 
  harbor 
  and 
  that 
  in 
  the 
  Niagara 
  river 
  

   outside 
  the 
  harbor 
  wall, 
  this 
  difference 
  of 
  water-level 
  amounting 
  

   to 
  from 
  4 
  feet 
  to 
  4.5 
  feet. 
  As 
  measured 
  in 
  the 
  spring 
  of 
  1896, 
  at 
  

   a 
  point 
  near 
  the 
  ship 
  lock, 
  it 
  was 
  about 
  4 
  feet. 
  According 
  to 
  

   the 
  report 
  of 
  the 
  Assembly 
  Committee 
  of 
  1870, 
  there 
  were 
  

   formerly 
  ten 
  mills 
  in 
  operation 
  at 
  Black 
  Rock, 
  using 
  2744 
  second- 
  

   feet 
  of 
  water. 
  The 
  power 
  developed 
  by 
  these 
  mills, 
  and 
  all 
  

   operating 
  at 
  full 
  capacity, 
  is 
  estimated 
  at 
  not 
  exceeding 
  520 
  

   horsepower. 
  Owing 
  to 
  the 
  decline 
  of 
  the 
  milling 
  business
