  granted 
  the 
  right 
  to 
  excavate 
  100 
  feet 
  down 
  the 
  face 
  of 
  the 
  bank. 
  

   In 
  1852, 
  when 
  this 
  contract 
  was 
  made, 
  the 
  use 
  of 
  waterpower 
  

   under 
  higher 
  heads 
  than 
  100 
  feet 
  was, 
  so 
  far 
  as 
  the 
  United 
  States 
  

   was 
  concerned, 
  entirely 
  unknown. 
  Until 
  recently 
  the 
  mills 
  at 
  

   Niagara 
  Falls 
  have 
  not 
  attempted 
  to 
  use 
  more 
  than 
  50 
  or 
  60 
  feet

  Hydraulic

  as

  sufficient, 
  by

  of 
  the

  to 
  produce 
  about 
  15,000 
  horsepower, 
  under 
  the

  capacity 
  was 
  exhausted 
  when 
  about 
  7000 
  horse-

  produced.
