  to 
  have 
  been 
  seriously 
  affected 
  by 
  strong 
  winds. 
  Still 
  the 
  daily 
  

   record 
  shows 
  that 
  there 
  must 
  have 
  been 
  some 
  wind 
  action. 
  The 
  

   current 
  velocities 
  were 
  obtained 
  after 
  the 
  methods 
  used 
  by 
  the 
  

   Mississippi 
  River 
  Commission 
  and 
  described 
  in 
  their 
  reports, 
  all 
  

   velocity 
  observations 
  being 
  taken 
  with 
  a 
  current 
  meter, 
  with 
  

   electrical 
  appliances 
  for 
  recording 
  the 
  number 
  of 
  revolutions. 
  

   The 
  following

  The 
  tabulation 
  shows 
  (1) 
  a 
  variation 
  in 
  lake 
  elevations, 
  as 
  indi- 
  

   cated 
  in 
  the 
  Buffalo 
  gage, 
  from

  24, 
  1891, 
  to 
  

   +0.15 
  on 
  May

  a 
  range 
  of 
  3.10 
  feet; 
  (2) 
  a 
  variation 
  in 
  

   discharge 
  of 
  72,114 
  cubic 
  feet 
  per 
  second. 
  There 
  are 
  some 
  dis- 
  

   crepancies 
  in 
  the 
  results 
  which 
  it 
  is 
  not 
  necessary 
  to 
  discuss 
  at 
  

   length 
  ; 
  but 
  in 
  the 
  absence 
  of 
  more 
  satisfactory 
  data 
  we 
  may 
  safely 
  

   assume, 
  in 
  view 
  of 
  the 
  foregoing 
  evidence 
  as 
  to 
  the 
  small 
  runoff 
  of 
  

   streams 
  tributary 
  to 
  and 
  in 
  the 
  vicinity 
  of 
  the 
  Great 
  Lakes, 
  that 
  

   the 
  figures 
  obtained 
  in 
  the 
  fall 
  of 
  1891 
  and 
  spring 
  of 
  1892, 
  are 
  more 
  

   nearly 
  correct 
  than 
  the 
  larger 
  figures 
  of 
  the 
  Lake 
  Survey. 
  By 
  

   plotting 
  the 
  observed 
  discharges 
  a 
  mean 
  discharge 
  curve 
  has 
  been 
  

   obtained', 
  from 
  which 
  the 
  discharge 
  of 
  the 
  river 
  att 
  points 
  within 
  

   the 
  range 
  of 
  the 
  observation 
  can 
  be 
  taken 
  off, 
  when 
  one 
  has 
  the 
  

   tabulated 
  nights 
  of 
  the 
  Buffalo 
  gage 
  before 
  him. 
  At 
  present 
  

   these 
  measurements 
  are, 
  on 
  the 
  whole, 
  not 
  considered 
  sufficiently
