  Power 
  Development 
  on 
  St 
  Lawrence 
  River 
  

  

  The 
  St 
  Lawrence 
  Power 
  Company. 
  Among 
  the 
  large 
  power 
  

   developments 
  under 
  construction 
  in 
  the 
  State 
  of 
  New 
  York 
  is 
  that 
  

   of 
  the 
  St 
  Lawrence 
  Power 
  Company 
  at 
  Masisena, 
  on 
  St 
  Law- 
  

   rence 
  and 
  Grasse 
  rivers. 
  The 
  plant 
  includes 
  the 
  excavation 
  of 
  

   a 
  canal 
  leading 
  from 
  the 
  St 
  Lawrence 
  river 
  to 
  Grasse 
  river, 
  a 
  dis- 
  

   tance 
  of 
  three 
  miles, 
  the 
  building 
  of 
  a 
  power-house, 
  together 
  

   with 
  the 
  installation 
  of 
  electric 
  generators' 
  and 
  the 
  necessary 
  

   equipment 
  of 
  turbine 
  water 
  Avheels. 
  The 
  furnishing 
  of 
  the 
  elec- 
  

   tric 
  apparatus 
  was 
  awarded 
  to 
  the 
  Westinghouse 
  Electrical 
  & 
  

   Manufacturing 
  Company. 
  

  

  The 
  plam 
  of 
  development 
  is 
  to 
  divert 
  a 
  portion 
  of 
  the 
  water 
  of 
  

   St 
  Lawrence 
  river 
  from 
  its 
  natural 
  channel 
  by 
  means 
  of 
  a 
  canal, 
  

   carrying 
  it 
  3 
  miles 
  across 
  to 
  Grasse 
  river, 
  where, 
  after 
  operating 
  

   turbines, 
  it 
  will 
  pass 
  by 
  way 
  of 
  Grasse 
  river 
  to 
  the 
  St 
  Lawrence 
  

   at 
  a 
  point 
  lower 
  down 
  stream. 
  Just 
  below 
  where 
  the 
  canal 
  takes 
  

   water 
  from 
  St 
  Lawrence 
  river 
  are 
  Long 
  Sault 
  rapids, 
  which 
  have 
  

   a 
  fall 
  of 
  about 
  50 
  feet. 
  Grasse 
  river 
  runs 
  nearly 
  parallel 
  to 
  the 
  

   St 
  Lawrence 
  for 
  several 
  miles, 
  flowing 
  into 
  it 
  a 
  short 
  distance 
  

   below 
  the 
  foot 
  of 
  Long 
  Sault 
  rapids. 
  To 
  the 
  south 
  of 
  the 
  

   St 
  Lawrence 
  river, 
  and 
  between 
  it 
  and 
  the 
  valley 
  of 
  Grasse 
  river, 
  

   there 
  is 
  a 
  comparatively 
  level 
  plateau. 
  

  

  The 
  average 
  width 
  of 
  Grasse 
  river 
  from 
  its 
  mouth 
  to 
  above 
  where 
  

   the 
  power 
  canal 
  will 
  intersect 
  it 
  is 
  from 
  250 
  to 
  300 
  feet, 
  and 
  its 
  

   water 
  surface, 
  for 
  that 
  portion, 
  is 
  substantially 
  on 
  a 
  level 
  with 
  

   St 
  Lawrence 
  below 
  the 
  rapids 
  ; 
  hence 
  the 
  surface 
  of 
  Grasse 
  river 
  

   at 
  the 
  point 
  where 
  the 
  power 
  canal 
  strikes 
  the 
  stream 
  is 
  from 
  

   45 
  to 
  50 
  feet 
  below 
  the 
  surface 
  of 
  the 
  St 
  Lawrence 
  at 
  the 
  head 
  

   of 
  the 
  canal. 
  The 
  power 
  station 
  will 
  be 
  located 
  on 
  the 
  north 
  

   bank 
  of 
  Grasse 
  river, 
  the 
  tail-water 
  dropping 
  into 
  that 
  stream, 
  

   which 
  thus 
  becomes, 
  in 
  effect, 
  a 
  tailrace 
  for 
  this 
  power
