  exceeded 
  5 
  or 
  6 
  inches. 
  These 
  conclusions, 
  it 
  must 
  be 
  understood, 
  

   are 
  based 
  on 
  present 
  conditions 
  of 
  forestation. 
  In 
  case 
  there 
  

   were 
  much 
  larger 
  forest 
  areas 
  in 
  that 
  vicinity 
  at 
  that 
  time, 
  the 
  

   runoffs 
  may 
  have 
  been 
  somewhat 
  larger. 
  

  

  At 
  Mexico 
  the 
  total 
  precipitation 
  for 
  the 
  year 
  1840 
  was 
  20.21 
  

   inches, 
  the 
  storage 
  period 
  of 
  that 
  year 
  being 
  9.73 
  inches. 
  The 
  

   runoff 
  probably 
  did 
  not 
  exceed 
  2 
  inches. 
  

  

  At 
  Mount 
  Morris 
  the 
  total 
  precipitation 
  of 
  the 
  year 
  1891 
  was 
  

   23.69 
  inches, 
  that 
  of 
  the 
  storage 
  period 
  being 
  10.24 
  inches. 
  In 
  

   1895 
  the 
  total 
  was 
  25.05 
  inches, 
  the 
  storage 
  period 
  giving 
  11.95 
  

   inches. 
  From 
  the 
  writer's 
  personal 
  knowledge 
  of 
  the 
  subject 
  he 
  

   has 
  no 
  hesitation 
  in 
  saying 
  that 
  in 
  1895 
  streams 
  in 
  the 
  vicinity 
  

   of 
  Mount 
  Morris 
  did 
  not 
  run 
  to 
  exceed 
  a 
  total 
  of 
  about 
  3 
  to 
  4 
  

   inches. 
  

  

  The 
  year 
  1895 
  was 
  generally 
  a 
  year 
  of 
  low 
  precipitation 
  

   throughout 
  the 
  whole 
  State. 
  Thus, 
  at 
  Newark 
  Valley 
  the 
  total 
  

   was 
  28.40 
  inches; 
  at 
  New 
  Lisbon, 
  the 
  total 
  was 
  29.93; 
  at 
  North 
  

   Hammond, 
  the 
  total 
  was 
  29.80, 
  and 
  so 
  on. 
  An 
  extended 
  analysis 
  

   of 
  the 
  precipitation 
  records 
  shows 
  that 
  for 
  a 
  large 
  portion 
  of 
  

   the 
  State 
  of 
  New 
  York 
  the 
  runoff 
  of 
  1895 
  did 
  not 
  exceed 
  6 
  to 
  12 
  

   inches 
  on 
  the 
  catchment 
  areas. 
  At 
  some 
  places 
  the 
  runoffs 
  were 
  

   less 
  than 
  6 
  inches. 
  At 
  Onondaga 
  Hollow 
  the 
  year 
  of 
  minimum 
  

   precipitation 
  occurred 
  in 
  1841, 
  having 
  been 
  preceded 
  by 
  several 
  

   years 
  of 
  rather 
  low 
  rainfall. 
  Streams 
  in 
  that 
  vicinity 
  probably 
  

   do 
  not 
  exceed 
  6 
  inches 
  runoff 
  in 
  years 
  of 
  minimum 
  precipitation. 
  

  

  At 
  Oswego 
  the 
  precipitation 
  sank 
  to 
  26.15 
  inches 
  in 
  1855 
  and 
  

   to 
  23.46 
  in 
  1887 
  ; 
  in 
  1889 
  it 
  was 
  30.39 
  inches. 
  In 
  1887 
  the 
  total 
  

   for 
  the 
  storage 
  period 
  was 
  10.55 
  inches. 
  It 
  is 
  doubtful 
  if 
  the 
  

   runoff 
  at 
  Oswego 
  exceeded 
  about 
  2 
  to 
  4 
  inches 
  for 
  that 
  year. 
  

  

  At 
  Oxford 
  we 
  have

  following 
  record
