  The 
  preceding 
  discussion 
  shows 
  that 
  while 
  the 
  Genesee 
  river 
  

   record 
  is 
  a 
  composite 
  one, 
  nevertheless 
  it 
  is 
  believed 
  to 
  be 
  a 
  

   good 
  record. 
  The 
  reason 
  for 
  this 
  belief 
  is 
  largely 
  founded 
  on 
  

   the 
  curve 
  as 
  per 
  fig.ll. 
  

  

  Gagings 
  have 
  also 
  been 
  kept 
  at 
  Mount 
  Morris 
  from 
  June 
  to 
  

   December, 
  1890, 
  and 
  at 
  Rochester 
  from 
  March, 
  1893, 
  to 
  the 
  

   present 
  time, 
  but 
  the 
  gagings 
  at 
  Rochester 
  are 
  not 
  very 
  reliable. 
  

   Possibly 
  some 
  method 
  of 
  correcting 
  them 
  may 
  be 
  worked 
  out 
  in 
  

   the 
  future. 
  

  

  In 
  table 
  No. 
  48, 
  a 
  comparison 
  has 
  been 
  made 
  of 
  the 
  measure- 
  

   ments 
  at 
  Rochester 
  with 
  those 
  at 
  Mount 
  Morris 
  for 
  the 
  water 
  

   years 
  1894-1896, 
  inclusive.
