  of 
  Glens 
  Falls,. 
  6 
  inches. 
  In 
  1884 
  the 
  precipitation 
  of 
  the 
  stor- 
  

   age 
  period 
  was 
  2.90 
  inches 
  greater 
  than 
  in 
  the 
  preceding 
  year, 
  

   but 
  this 
  small 
  additional 
  precipitation 
  was 
  probably 
  mostly 
  

   without 
  effect 
  on 
  the 
  streams 
  because 
  of 
  low 
  ground-water. 
  

   It 
  appears, 
  therefore, 
  entirely 
  safe 
  to 
  assume 
  that 
  the 
  runoff 
  of 
  

   streams 
  in 
  the 
  vicinity 
  of 
  Glens 
  Falls 
  must 
  have 
  been 
  quite 
  as 
  low 
  

   in 
  1884 
  as 
  in 
  the 
  previous 
  year 
  1883. 
  

  

  At 
  Gouverneur 
  the 
  total 
  precipitation 
  of 
  the 
  year 
  1838 
  was 
  

   20.93 
  inches; 
  of 
  1839, 
  18.87 
  inches, 
  and 
  of 
  1842, 
  17.06 
  inches. 
  

   Assuming 
  forestry 
  conditions 
  at 
  that 
  time 
  in 
  the 
  vicinity 
  of 
  Gou- 
  

   verneur 
  substantially 
  as 
  they 
  now 
  exist 
  on 
  the 
  Hudson 
  river 
  catch- 
  

   ment 
  area, 
  the 
  runoff 
  of 
  the 
  streams 
  may 
  have 
  been 
  3 
  inches, 
  or 
  

   from 
  deforested 
  areas 
  probably 
  2 
  inches. 
  

  

  At 
  Ithaca 
  the 
  two 
  lowest 
  years 
  of 
  precipitation 
  are 
  1884 
  and 
  

   1895, 
  in 
  both 
  of 
  which 
  the 
  total 
  happens 
  to 
  be 
  26.98 
  inches. 
  In 
  

   1846 
  the 
  total 
  of 
  the 
  storage 
  period 
  was 
  9.67 
  inches, 
  the 
  total 
  

   for 
  the 
  year 
  being 
  30.07 
  inches. 
  It 
  is 
  probable 
  that 
  the 
  extreme 
  

   minimum 
  runoff 
  in 
  the 
  vicinity 
  of 
  Ithaca 
  does 
  not 
  exceed 
  5 
  inches. 
  

  

  At 
  Keene 
  Valley 
  the 
  lowest 
  precipitation 
  recorded 
  occurred 
  in 
  

   1881, 
  the 
  total 
  for 
  that 
  year 
  being 
  28.20 
  inches. 
  The 
  precipita- 
  

   tion 
  of 
  the 
  storage 
  period 
  was 
  13.15 
  inches. 
  The 
  totals 
  of 
  the 
  

   previous 
  years, 
  1879 
  and 
  1880, 
  were 
  32.15 
  and 
  33.32 
  inches, 
  re- 
  

   spectively. 
  The 
  runoff 
  for 
  1881 
  probably 
  did 
  not 
  exceed 
  8.9 
  inches. 
  

  

  At 
  Lowville 
  the 
  period 
  of 
  lowest 
  precipitation 
  was 
  for 
  the 
  

  

  years 
  1843-1846, 
  inclusive. 
  The 
  following 
  are 
  the 
  figures 
  for 
  those

  A 
  marked 
  peculiarity 
  of 
  this 
  Lowville 
  period 
  is 
  the 
  low 
  pre- 
  

   cipitation 
  of 
  the 
  storage 
  period 
  for 
  all 
  the 
  years 
  included. 
  Taking 
  

   this 
  into 
  account, 
  it 
  is 
  probable 
  that 
  for 
  the 
  years 
  1845 
  and 
  1846 
  

   the 
  runoff 
  in 
  the 
  vicinity 
  of 
  Lowville 
  was 
  very 
  low. 
  In 
  1845 
  it 
  

   may 
  have 
  reached 
  8 
  inches, 
  but 
  for 
  1846 
  it 
  is 
  doubtful 
  if 
  it
