  The 
  Hudson 
  River 
  Power 
  Transmission 
  Company. 
  Among 
  the 
  

   important 
  developments 
  on 
  the 
  Hudson 
  river 
  mention 
  may 
  be 
  

   made 
  of 
  the 
  plant 
  of 
  the 
  Hudson 
  River 
  Power 
  Transmission 
  

   Company, 
  two 
  miles 
  below 
  Mechanicville. 
  This 
  plant 
  is 
  eleven 
  

   miles 
  from 
  Troy, 
  eighteen 
  miles 
  from 
  Albany, 
  and 
  seventeen 
  

   miles 
  from 
  Schenectady. 
  

  

  The 
  Hudson 
  river 
  is 
  here 
  divided 
  by 
  an 
  island 
  into 
  two 
  channels 
  

   with 
  a 
  total 
  width 
  of 
  about 
  1200 
  feet. 
  The 
  dam 
  and 
  power-house 
  

   were 
  constructed 
  in 
  1897 
  and 
  1898. 
  The 
  western 
  channel 
  of 
  the 
  

   river 
  is 
  used 
  for 
  power 
  head 
  and 
  tailrace. 
  The 
  dam 
  is 
  15 
  feet 
  

   high 
  above 
  the 
  river, 
  8 
  feet 
  thick 
  a 
  short 
  distance 
  below 
  the 
  crest 
  

   and 
  16 
  feet 
  through 
  the 
  face. 
  The 
  original 
  length 
  of 
  the 
  spillway, 
  

   which 
  was 
  situated 
  on 
  the 
  east 
  side 
  of 
  the 
  island, 
  was 
  707 
  feet, 
  

   hut 
  since 
  the 
  original 
  construction 
  an 
  additional 
  spillway, 
  143 
  

   feet 
  long, 
  has 
  been 
  added 
  by 
  removing 
  the 
  earth 
  and 
  rock 
  from 
  

   the 
  river 
  bank, 
  one 
  foot 
  lower 
  than 
  the 
  crest 
  of 
  the 
  main 
  dam. 
  

   The 
  power-house 
  of 
  concrete 
  is 
  at 
  the 
  west 
  end 
  of 
  the 
  dam 
  and 
  

   may 
  be 
  considered 
  as 
  a 
  continuation 
  thereof.
