  — 
  A 
  recent 
  circular 
  

   gives 
  a 
  detailed 
  statement 
  of 
  the 
  developed 
  water 
  power 
  in 
  

   Canada 
  to 
  Jan. 
  1, 
  1920. 
  It 
  states 
  that 
  "according 
  to 
  the 
  statis- 
  

   tics 
  just 
  compiled 
  there 
  is 
  installed 
  throughout 
  the 
  Dominion 
  

   some 
  2,418,000 
  turbine 
  or 
  water-wheel 
  horse 
  power 
  of 
  which 
  

   2,215,000 
  horse 
  power 
  is 
  actually 
  and 
  regularly 
  employed 
  in 
  use- 
  

   ful 
  work. 
  A 
  large 
  number 
  of 
  the 
  plants 
  now 
  operating 
  are 
  

   designed 
  for 
  the 
  addition 
  of 
  further 
  units 
  as 
  the 
  market 
  de- 
  

   mands. 
  The 
  ultimate 
  capacity 
  of 
  such 
  plants, 
  together 
  with 
  

   that 
  of 
  new 
  plants 
  now 
  under 
  construction, 
  total 
  some 
  3,385,000 
  

   horse 
  power. 
  Of 
  the 
  total 
  power 
  installed, 
  1,756,791 
  h. 
  p. 
  or 
  

   72-7

  cent, 
  is 
  installed 
  in 
  central 
  electric 
  stations, 
  which 
  are 
  

   engaged 
  in 
  the 
  development 
  of 
  electrical 
  energy 
  for 
  sale 
  and 
  

   distribution, 
  for 
  lighting, 
  mining, 
  electro-chemical 
  and 
  electro- 
  

   metallurgical 
  industry, 
  milling 
  and 
  general 
  manufacturing. 
  In 
  

   the 
  pulp 
  and 
  paper 
  industry 
  473,265 
  h. 
  p. 
  is 
  utilized 
  of 
  which 
  

   381,631 
  h. 
  p. 
  is 
  generated 
  directly 
  from 
  water 
  in 
  pulp 
  and

   establishments 
  while 
  91,634 
  h.

  is 
  purchased 
  from

  Hydro 
  power 
  used 
  for 
  other 
  purposes 
  and 
  

   other 
  industries 
  is

  These 
  figures 
  

   are 
  evidence 
  of 
  the 
  widespread 
  manner 
  in 
  which 
  the 
  Dominion's 
  

   water 
  power 
  resources 
  are 
  being 
  applied 
  to 
  the 
  furtherance 
  of 
  

   its 
  industrial 
  development.
