  thus 
  far 
  made. 
  The 
  reasons 
  for 
  This 
  view 
  may 
  be 
  derived 
  from 
  

   the 
  preceding 
  discussion 
  of 
  the 
  runoff 
  of 
  Niagara 
  river.

  St 
  Lawrence 
  river. 
  According 
  to 
  the 
  report 
  of 
  the 
  Deep 
  Water- 
  

   ways 
  Commission, 
  the 
  area 
  of 
  the 
  water 
  surface 
  of 
  Lake 
  Ontario 
  

   is 
  7450 
  square 
  miles, 
  and 
  the 
  area 
  of 
  the 
  tributary 
  catchment, 
  

   exclusive 
  of 
  the 
  area 
  of 
  the 
  lake 
  itself, 
  25,530 
  square 
  miles. 
  The 
  

   total 
  area 
  of 
  the 
  catchment 
  basin, 
  including 
  both 
  land 
  and 
  water 
  

   surfaces, 
  is 
  32,980 
  square 
  miles. 
  The 
  area 
  of 
  the 
  water 
  sur- 
  

   face 
  of 
  -St 
  Lawrence 
  river 
  from 
  Gallops 
  rapids 
  to 
  Montreal 
  2 
  is 
  

   given 
  at 
  220 
  square 
  miles, 
  and 
  the 
  area 
  of 
  the 
  tributary 
  catchment 
  

   at 
  5710 
  square 
  miles; 
  hence 
  the 
  total 
  area 
  of 
  the 
  basin 
  of 
  the 
  

   St 
  Lawrence 
  from 
  Gallops 
  to 
  Montreal 
  becomes 
  5930 
  square 
  

   miles. 
  

  

  In 
  the 
  foregoing 
  figures 
  Lake 
  Ontario 
  is 
  considered 
  as 
  beginning 
  

   in 
  Niagara 
  river, 
  at 
  the 
  foot 
  of 
  Niagara 
  Falls 
  and 
  terminating 
  

   at 
  the 
  head 
  of 
  Gallops 
  rapids, 
  whence 
  the 
  following 
  subdivisions 
  

   of 
  water-surface 
  area 
  are 
  derived; 
  Niagara 
  river, 
  5 
  square 
  miles; 
  

   Lake 
  Ontario 
  proper, 
  7260 
  square 
  miles; 
  St. 
  Lawrence 
  river, 
  185 
  

   square 
  miles 
  ; 
  giving 
  a 
  total, 
  as 
  above, 
  of 
  7450 
  square 
  miles. 
  

  

  Of 
  the 
  total 
  area 
  of 
  catchment 
  of 
  25,530 
  square 
  miles, 
  14,275 
  

   square 
  miles 
  lie 
  within 
  the 
  State 
  of 
  New 
  York 
  and 
  11,255 
  square
