  The 
  method 
  of 
  using 
  the 
  power 
  here 
  is 
  about 
  the 
  same 
  as 
  used 
  

   by 
  all 
  great 
  water 
  power 
  sites. 
  That 
  is, 
  the 
  water 
  is 
  lead 
  to 
  the 
  

   turbines 
  of 
  one 
  mill, 
  the 
  spent 
  water 
  flowing 
  along 
  a 
  canal 
  to 
  the 
  

   next 
  mill, 
  the 
  turbine 
  of 
  which 
  is 
  about 
  ten 
  feet 
  below 
  the 
  level 
  

   of 
  the 
  first, 
  and 
  so 
  on. 
  In 
  Cohoes 
  the 
  water 
  is 
  used 
  at 
  five 
  levels 
  

   with 
  a 
  fall 
  at 
  each 
  level 
  of 
  about 
  twenty 
  feet. 
  

  

  The 
  minimum 
  total 
  horse 
  power 
  developed 
  is 
  10,000. 
  This 
  is 
  

   estimated 
  for 
  the 
  dryest 
  season. 
  

  

  The 
  power 
  is 
  sufficient 
  for 
  the 
  mills 
  throughout 
  the 
  entire 
  

   year. 
  Xo 
  supplementary 
  steam 
  power 
  is 
  needed. 
  There 
  is 
  yet 
  

   power 
  to 
  spare. 
  

  

  The 
  bare 
  statement 
  that 
  the 
  Mohawk 
  supplies 
  10,000 
  horse 
  

   power 
  gives 
  to 
  the 
  uniniated 
  but 
  a 
  faint 
  idea 
  of 
  its 
  value. 
  To 
  

   put 
  the 
  same 
  fact 
  in 
  a 
  different 
  form, 
  the 
  city 
  of 
  Cohoes 
  has 
  

   about 
  25,000 
  inhabitants. 
  Of 
  this 
  total 
  population 
  sixty 
  per 
  cent, 
  

   or 
  15,000, 
  are 
  employed 
  in 
  the 
  knitting, 
  spinning 
  and 
  iron 
  mills, 
  

   and 
  in 
  the 
  electric 
  light 
  and 
  power 
  plants. 
  One 
  mill 
  alone, 
  w 
  The 
  

   Harmony," 
  when 
  working 
  on 
  full 
  time 
  employs 
  6,000 
  hands. 
  

  

  The 
  accompanying 
  plates 
  show 
  both 
  the 
  falls 
  and 
  the 
  gate 
  

   house. 
  The 
  plate 
  of 
  the 
  gate 
  house 
  was 
  reproduced 
  from 
  a 
  very 
  

   large 
  photograph 
  in 
  the 
  office 
  of 
  the 
  Cohoes 
  Company 
  at 
  Cohoes. 
  

  

  The 
  plate 
  of 
  the 
  falls 
  shows 
  the 
  dam 
  in 
  the 
  distant 
  back- 
  

   ground. 
  The 
  view 
  was 
  taken 
  at 
  low 
  water, 
  since 
  at 
  high 
  water 
  

   the 
  clouds 
  of 
  mist 
  and 
  spray 
  completely 
  blot 
  out 
  the 
  surround- 
  

   ings. 
  

  

  At 
  Kenwood, 
  two 
  miles 
  south 
  of 
  Albany, 
  the 
  Kenwood 
  grist 
  

   mills 
  and 
  the 
  Kenwood 
  felt 
  mills'* 
  are 
  supplied 
  with 
  power 
  by 
  

   about 
  thirty-eight 
  feet 
  of 
  fall 
  in 
  the 
  ISormanskill 
  creek. 
  The 
  

   total 
  horse 
  power 
  developed 
  is 
  about 
  150. 
  At 
  the 
  felt 
  mills 
  steam 
  

   is 
  used 
  to 
  supplement 
  the 
  water 
  power. 
  

  

  At 
  Alcove, 
  JS'ormansville, 
  South 
  Berne, 
  Coeymans 
  Hollow, 
  

   Rensselaerville, 
  and 
  other 
  places 
  in 
  the 
  county, 
  there 
  are 
  small 
  

   grist 
  and 
  saw 
  mills 
  for 
  local 
  work 
  only.
