  order 
  that 
  the 
  water 
  may 
  be 
  divided 
  equally 
  between 
  these 
  two 
  

   canals 
  both 
  have 
  the 
  same 
  aggregate 
  waterway 
  at 
  the 
  head 
  

   gates, 
  and 
  by 
  gages 
  on 
  both 
  sides, 
  which 
  are 
  examined 
  whenever 
  

   necessary, 
  it 
  can 
  be 
  seen 
  whether 
  one 
  canal 
  is 
  drawn 
  below 
  the 
  

   other, 
  and 
  the 
  gates 
  changed 
  accordingly. 
  On 
  this 
  canal 
  there 
  

   are 
  recognized 
  50 
  first-class 
  runs, 
  17 
  second-class, 
  and 
  an 
  un- 
  

   limited 
  number 
  of 
  third-class. 
  For 
  first-class 
  runs 
  the 
  rental 
  is 
  

   from 
  |250 
  to 
  |300 
  per 
  annum; 
  for 
  second 
  and 
  third 
  class 
  it 
  ranges 
  

   from 
  $125 
  to 
  $150. 
  By 
  a 
  decree 
  of 
  the 
  Supreme 
  Court, 
  dated 
  

   August 
  21, 
  1875, 
  a 
  run 
  of 
  water 
  on 
  the 
  Varick 
  canal 
  ranges 
  

   between 
  28 
  cubic 
  feet 
  per 
  second, 
  under 
  a 
  head 
  of 
  12 
  feet, 
  and 
  

   25 
  cubic 
  feet 
  per 
  second, 
  under 
  a 
  head 
  of 
  13 
  feet. 
  The 
  actual 
  

   working 
  head 
  is, 
  however, 
  ordinarily 
  only 
  about 
  10 
  feet, 
  so 
  that 
  

   on 
  the 
  foregoing 
  basis 
  a 
  run 
  of 
  water 
  may 
  be 
  taken 
  as 
  33.3 
  cubic 
  

   feet 
  per 
  second. 
  At 
  the 
  price 
  of 
  first-class 
  runs 
  of 
  from 
  $250 
  to 
  

   $300, 
  and 
  with 
  75 
  per 
  cent 
  efficiency, 
  the 
  cost 
  per 
  horsepower 
  per 
  

   annum 
  varies 
  from 
  $8.80 
  to 
  $10.56, 
  a 
  run 
  on 
  the 
  Varick 
  canal 
  

   being 
  equal 
  to 
  33.3 
  cubic 
  feet 
  per 
  second 
  on 
  10 
  feet 
  head, 
  an 
  

   amount 
  of 
  water 
  which 
  yields 
  37.9 
  horsepower 
  under 
  that 
  head. 
  

  

  As 
  to 
  the 
  difference 
  in 
  cost 
  of 
  water 
  on 
  these 
  two 
  canals 
  at 
  

   Oswego, 
  it 
  may 
  be 
  pointed 
  out 
  that 
  the 
  Oswego 
  Canal 
  Company's 
  

   race 
  has 
  a 
  substantial 
  advantage 
  over 
  the 
  Varick 
  race, 
  in 
  that 
  it 
  

   extends 
  to 
  the 
  harbor, 
  enabling 
  vessels 
  to 
  come 
  directly 
  along- 
  

   side 
  of 
  the 
  mills. 
  Moreover, 
  the 
  division 
  of 
  water 
  rights 
  is 
  such 
  

   that 
  a 
  first-class 
  run 
  of 
  water 
  can 
  always 
  be 
  depended 
  on 
  along 
  

   the 
  Oswego 
  Canal 
  Company's 
  race, 
  but 
  can 
  not 
  on 
  Varick 
  canal.

  At 
  Cohoes 
  we 
  have 
  the 
  great 
  power 
  development 
  built 
  up 
  by 
  

   the 
  Cohoes 
  Company, 
  which 
  has, 
  by 
  careful 
  management 
  of 
  the 
  

   waterpower, 
  built 
  up 
  at 
  this 
  place 
  a 
  fine 
  manufacturing 
  city 
  of 
  

   24,000 
  inhabitants. 
  

  

  The 
  Cohoes 
  Company 
  not 
  only 
  owns 
  all 
  of 
  the 
  hydraulic 
  canals, 
  

   but 
  also 
  the 
  land 
  adjoining 
  the 
  canals. 
  It 
  gives 
  to 
  manufac- 
  

   turers 
  a 
  perpetual 
  lease 
  of 
  land 
  and 
  water, 
  the 
  entire 
  property 
  

   leased 
  remaining 
  subject 
  to 
  a 
  rental 
  of 
  $200 
  per 
  year 
  per 
  mill 
  

   power. 
  On 
  this 
  basis 
  the 
  land 
  is 
  regarded 
  as 
  donated 
  and 
  the 
  

   rental 
  applies 
  only 
  to 
  the 
  waterpower.
