  The 
  second 
  change 
  is 
  to 
  do 
  away 
  with 
  the 
  two 
  aqueducts 
  across 
  

   the 
  Mohawk 
  river 
  and 
  the 
  portion 
  of 
  the 
  canal 
  in 
  Saratoga 
  county 
  . 
  

   This 
  is 
  to 
  be 
  done 
  by 
  throwing 
  the 
  canal 
  into 
  the 
  Mohawk 
  at 
  

   Rexford 
  Flats, 
  and 
  following 
  down 
  the 
  river 
  to 
  the 
  vicinity 
  of 
  

   the 
  great 
  falls 
  of 
  the 
  Mohawk 
  at 
  Cohoes. 
  

  

  The 
  third 
  change 
  is 
  at 
  the 
  West 
  Troy 
  side-cut 
  where, 
  instead 
  

   of 
  the 
  awkward 
  right 
  angle 
  turn 
  requiring 
  even 
  small 
  boats 
  to 
  

   uncouple, 
  a 
  diagonal 
  deflection 
  is 
  made 
  which 
  will 
  enable 
  fleets 
  

   to 
  pass 
  directly 
  and 
  conveniently 
  into 
  the 
  Hudson 
  without 
  

   breaking 
  up. 
  

  

  3) 
  Pneumatic 
  or 
  other 
  mechanical 
  locks 
  or 
  appliances 
  for 
  

   the 
  passage 
  of 
  boats 
  to 
  be 
  provided 
  at 
  Cohoes 
  and 
  Lockport, 
  and 
  

   possibly 
  at 
  Newark. 
  All 
  other 
  locks 
  (one 
  of 
  each 
  pair) 
  to 
  be 
  

   lengthened 
  and 
  enlarged 
  to 
  take 
  in 
  two 
  boats 
  of 
  125 
  feet 
  length,

  The 
  locks 
  to 
  be 
  provided 
  

   with 
  water-power 
  generating 
  apparatus 
  wherever 
  necessary, 
  with 
  

   steel 
  quick-acting 
  quadrant 
  gates, 
  equipped 
  with 
  spring 
  buffers, 
  

   or 
  other 
  gates 
  equally 
  good, 
  with 
  power 
  capstans 
  at 
  each 
  end 
  of 
  

   the 
  lock 
  for 
  pulling 
  the 
  boats 
  in 
  and 
  out, 
  and 
  generally 
  with 
  every- 
  

   thing 
  of 
  the 
  most 
  modern 
  and 
  up-to-date 
  character. 
  The 
  other 
  

   small 
  lock 
  of 
  each 
  pair 
  of 
  locks 
  to 
  be 
  lengthened 
  to 
  take 
  in 
  one 
  

   boat 
  125 
  feet 
  long. 
  

  

  On 
  a 
  canal 
  by 
  this 
  plan 
  the 
  cost 
  per 
  ton 
  for 
  carrying 
  freight 
  

   from 
  Buffalo 
  to 
  New 
  York 
  would 
  be 
  44 
  cents; 
  the 
  cost 
  per 
  bushel, 
  

   1.32 
  cents, 
  and 
  the 
  cost 
  per 
  ton 
  mile, 
  0.88 
  mill. 
  

  

  The 
  enlarged 
  canal. 
  After 
  giving 
  due 
  consideration 
  to 
  the 
  vari- 
  

   ous 
  features 
  of 
  the 
  problem, 
  the 
  Canal 
  Committee 
  decided 
  that 
  if 
  

   the 
  canal 
  were 
  to 
  be 
  materially 
  enlarged 
  its 
  new 
  dimensions 
  

   sliould 
  be 
  such 
  as 
  would 
  fit 
  it 
  for 
  use 
  by 
  barges 
  of 
  150 
  feet 
  length, 
  

   25 
  feet 
  width, 
  and 
  10 
  feet 
  draft 
  of 
  water, 
  with 
  all 
  locks 
  arranged 
  

   to 
  take 
  in 
  two 
  boats 
  coupled 
  together 
  tandem.
