  teresting 
  to 
  note 
  that 
  the 
  recent 
  projects 
  have 
  returned 
  to 
  the 
  

   canalization 
  of 
  streams. 
  

  

  Among 
  the 
  changes 
  proposed 
  by 
  Mr 
  Sweet, 
  in 
  his 
  paper 
  in 
  

   1884, 
  were 
  the 
  following 
  : 
  

  

  One 
  essential 
  change 
  in 
  profile 
  consists 
  in 
  extending 
  the 
  Rome 
  

   level 
  westward 
  to 
  lock 
  57, 
  between 
  Newark 
  and 
  Lyons, 
  in 
  Wayne 
  

   county, 
  throwing 
  out 
  the 
  locks 
  47 
  to 
  56, 
  inclusive. 
  This 
  change 
  

   in 
  profile 
  can 
  be 
  effected 
  by 
  swinging 
  the 
  route 
  to 
  the 
  southward, 
  

   near 
  Newark, 
  crossing 
  the 
  Canandaigua 
  outlet 
  and 
  occupying 
  

   ground 
  of 
  the 
  proper 
  elevation 
  along 
  the 
  south 
  side 
  of 
  the 
  Clyde 
  

   river, 
  and 
  crossing 
  the 
  Seneca 
  river 
  at 
  the 
  narrowest 
  part 
  of 
  its 
  

   valley, 
  which 
  is 
  near 
  its 
  junction 
  with 
  the 
  outlet 
  of 
  Cayuga 
  lake, 
  

   from 
  whence 
  it 
  should 
  gradually 
  approach 
  the 
  present 
  route 
  of 
  

   the 
  canal 
  and 
  connect 
  with 
  or 
  cross 
  it 
  just 
  east 
  of 
  the 
  city 
  of 
  

   Svracuse.

  Mr 
  Sweet 
  states 
  that 
  the 
  only 
  serious 
  difficulty 
  encountered 
  

   on 
  this 
  route 
  is 
  the 
  crossing 
  of 
  the 
  Seneca 
  river, 
  where 
  the 
  water 
  

   surface 
  of 
  the 
  canal 
  must 
  be 
  nearly 
  50 
  feet 
  above 
  that 
  of 
  the 
  

   river, 
  and 
  for 
  nearly 
  two 
  miles 
  over 
  40 
  feet 
  above 
  the 
  surface 
  

   upon 
  which 
  its 
  embankment 
  must 
  be 
  built. 
  

  

  This 
  change 
  of 
  route, 
  to 
  secure 
  a 
  continuously 
  descending 
  pro- 
  

   file 
  from 
  the 
  lake 
  to 
  the 
  Hudson 
  river, 
  is 
  the 
  only 
  deviation 
  from 
  

   the 
  route 
  of 
  the 
  old 
  canal 
  that 
  is 
  absolutely 
  necessary, 
  but 
  it 
  is 
  

   believed 
  that 
  the 
  construction 
  would 
  be 
  simplified 
  and 
  cheapened, 
  

   and 
  the 
  best 
  possible 
  waterway 
  secured 
  by 
  the 
  adoption 
  of 
  an 
  

   entirely 
  new 
  route 
  from 
  Syracuse 
  eastward. 
  

  

  Lower 
  ground 
  can 
  be 
  obtained 
  for 
  the 
  Home 
  level, 
  except 
  at 
  

   the 
  summit 
  itself, 
  by 
  moving 
  the 
  line 
  northward; 
  thus 
  by 
  lower- 
  

   ing 
  the 
  elevation 
  of 
  this 
  level 
  throughout, 
  lessening 
  the 
  difficul- 
  

   ties 
  of 
  the 
  Seneca 
  river 
  crossing, 
  and 
  from 
  a 
  point 
  a 
  little 
  west 
  

   of 
  Utica 
  eastward 
  to 
  the 
  Hudson, 
  the 
  Mohawk 
  river 
  should 
  be 
  

   canalized 
  by 
  the 
  erection 
  of 
  locks 
  and 
  movable 
  dams 
  at 
  suitable 
  

   points 
  in 
  its 
  course, 
  and 
  the 
  deepening 
  and 
  rectification 
  of 
  its 
  

   channel.
