  RUNOFF 
  OF 
  OTHER 
  STREAMS 
  OF 
  NEW 
  YORK 
  

  

  Aside 
  from 
  Niagara 
  river, 
  comparatively 
  little 
  definite 
  informa- 
  

   tion 
  as 
  to 
  the 
  runoff 
  of 
  streams 
  in 
  New 
  York 
  was 
  available 
  before 
  

   1898. 
  Rather 
  singularly, 
  aside 
  from 
  gagings 
  made 
  by 
  John 
  B. 
  

   Jervis 
  in 
  1835 
  of 
  Madison 
  and 
  Eaton 
  brooks, 
  the 
  State 
  of 
  New 
  

   York 
  had 
  never 
  made 
  any 
  gagings, 
  although 
  one 
  might 
  suppose 
  

   that 
  in 
  view 
  of 
  its 
  development 
  of 
  an 
  extensive 
  canal 
  system 
  

   earlier 
  than 
  this 
  it 
  would 
  have 
  investigated 
  this 
  important 
  branch 
  

   of 
  hydrology.

  few 
  streams 
  gaged

  been 
  kept 
  by

  Canal 
  Department

  State 
  for 
  a 
  good 
  

   many 
  years, 
  but 
  precise 
  measurements

  one-half 
  miles 
  below 
  the
