  The 
  low 
  precipitation 
  of 
  the 
  storage 
  period 
  of 
  the 
  water 
  year 
  

   1834 
  indicates 
  runoffs 
  in 
  the 
  vicinity 
  of 
  Oxford 
  for 
  that 
  year 
  of 
  

   perhaps 
  5 
  inches. 
  

  

  At 
  Palermo, 
  where 
  there 
  is 
  a 
  continuous 
  record 
  from 
  1854-1898, 
  

   inclusive, 
  there 
  are 
  several 
  years 
  in 
  which 
  the 
  precipitation 
  is 
  

   given 
  considerably 
  below 
  30 
  inches, 
  as 
  for 
  instance 
  in 
  1871, 
  27.81 
  

   inches 
  ; 
  in 
  1875, 
  28.11 
  inches 
  ; 
  in 
  1881, 
  26.37 
  inches 
  ; 
  in 
  1882, 
  28.86 
  

   inches, 
  and 
  in 
  1895, 
  25.97 
  inches. 
  The 
  precipitation 
  of 
  the 
  

   storage 
  period 
  of 
  1895 
  was 
  only 
  10.15 
  inches. 
  It 
  is 
  probable 
  that 
  

   for 
  that 
  year 
  streams 
  in 
  the 
  vicinity 
  of 
  Palermo 
  did 
  not 
  exceed 
  a 
  

   runoff 
  of 
  2 
  inches. 
  

  

  At 
  Penn 
  Yan 
  there 
  is 
  a 
  continuous 
  record 
  from 
  1829-1867, 
  

   inclusive, 
  the 
  mean 
  of 
  the 
  whole 
  period 
  being 
  27.93 
  inches. 
  

   There 
  are 
  several 
  periods 
  of 
  from 
  three 
  to 
  six 
  years 
  when 
  the 
  

   rainfall 
  was 
  less 
  than 
  the 
  average. 
  So 
  marked 
  is 
  this 
  that 
  it 
  

   seems 
  safe 
  to 
  assume 
  that 
  streams 
  in 
  the 
  vicinity 
  of 
  Penn 
  Yan 
  

   do 
  not 
  ordinarily 
  run 
  more 
  than 
  from 
  4 
  to 
  6 
  inches 
  on 
  the 
  catch- 
  

   ment 
  area. 
  In 
  1854 
  the 
  total 
  precipitation 
  was 
  19.66 
  inches. 
  

   There 
  are 
  several 
  years 
  in 
  which 
  the 
  total 
  precipitation 
  at 
  Penn 
  

   Yan 
  for 
  the 
  storage 
  period 
  has 
  not 
  exceeded 
  from 
  8 
  to 
  9 
  inches. 
  

  

  At 
  Pierpont 
  Manor 
  the 
  totals 
  for 
  the 
  years 
  1852-1854 
  are 
  as 
  

   follows: 
  1852, 
  30.93 
  inches; 
  1853, 
  27.57 
  inches, 
  and 
  for 
  1854, 
  . 
  

   28.89 
  inches. 
  In 
  1862 
  the 
  total 
  precipitation 
  was 
  28.15 
  inches. 
  

  

  At 
  Plattsburg 
  the 
  total 
  precipitation 
  in 
  1858 
  was 
  29.11 
  inches 
  

   and 
  in 
  1859, 
  22.78 
  inches. 
  In 
  1893 
  it 
  was 
  25.69 
  inches, 
  with 
  a 
  

   total 
  of 
  only 
  9.92 
  inches 
  in 
  the 
  storage 
  period. 
  For 
  1895 
  the 
  

   total 
  was 
  29.75 
  inches. 
  It 
  is 
  evident 
  that 
  the 
  minimum 
  runoff 
  of 
  

   streams 
  in 
  the 
  vicinity 
  of 
  Plattsburg 
  does 
  not 
  exceed 
  6 
  inches. 
  

  

  At 
  Pompey 
  the 
  totals 
  for 
  the 
  years 
  1836-1838 
  are 
  as 
  follows: 
  

   For 
  1836, 
  24.22 
  inches; 
  1837, 
  28.37 
  inches, 
  and 
  for 
  1838, 
  24.82 
  

   inches. 
  

  

  At 
  Port 
  Ontario 
  the 
  total 
  precipitation 
  for 
  1855 
  was 
  26.15 
  

   inches; 
  for 
  1871, 
  29.76 
  inches, 
  and 
  for 
  1872, 
  28.81 
  inches. 
  

  

  At 
  Potsdam 
  we 
  have 
  the 
  following 
  record 
  for 
  the 
  years 
  1837- 
  

   1839, 
  inclusive:
