  precipitation 
  by

  districts,

  (7) 
  excessive 
  precipita- 
  

   tion. 
  

  

  The 
  chapter 
  on 
  " 
  Excessive 
  precipitation 
  " 
  is 
  probably, 
  from 
  an 
  

   engineering 
  point 
  of 
  view, 
  the 
  most 
  important. 
  Mr 
  Henry 
  states 
  

   that 
  in 
  1888 
  attention 
  was 
  first 
  directed 
  to 
  the 
  importance 
  of 
  

   statistics 
  of 
  excessive 
  rainfall. 
  At 
  the 
  present 
  time 
  the 
  Monthly 
  

   Weather 
  Keview 
  publishes 
  a 
  table 
  of 
  maximum 
  rainfalls 
  in 
  five 
  

   and 
  ten 
  minute 
  and 
  one 
  hour 
  periods, 
  etc. 
  

  

  Table 
  No. 
  VIII 
  of 
  Mr 
  Henry's 
  paper 
  gives 
  details 
  of 
  excessive 
  

   rainfall 
  at 
  Washington, 
  Savannah, 
  and 
  St 
  Louis, 
  and 
  table 
  

   No. 
  IX 
  gives 
  maximum 
  intensity 
  of 
  rainfall 
  for 
  periods 
  of 
  five, 
  

   ten, 
  and 
  sixty 
  minutes 
  at 
  the 
  Weather 
  Bureau 
  stations 
  equipped 
  

   with 
  self-registering 
  gages, 
  compiled 
  from 
  all 
  available 
  records. 
  

   Inasmuch 
  as 
  this 
  paper 
  may 
  be 
  readily 
  referred 
  to 
  further 
  detail 
  

   is 
  omitted. 
  

  

  Measurement 
  of 
  rainfall. 
  The 
  subject, 
  " 
  How 
  close 
  may 
  rain- 
  

   fall 
  be 
  measured?" 
  has 
  been 
  fully 
  discussed 
  by 
  Prof. 
  Cleveland 
  

   Abbe. 
  1 
  Professor 
  Abbe 
  states 
  that 
  the 
  influence 
  of 
  altitude 
  was 
  

   first 
  brought 
  to 
  the 
  attention 
  of 
  the 
  learned 
  world 
  by 
  Heberden 
  

   who, 
  in 
  1769, 
  in 
  a 
  memoir 
  in 
  the 
  Transactions 
  of 
  the 
  Royal 
  Society 
  

   of 
  London, 
  stated 
  that 
  a 
  gage 
  on 
  Westminster 
  Abbey, 
  over 
  150 
  feet 
  

   above 
  the 
  ground, 
  caught 
  less 
  than 
  half 
  as 
  much 
  as 
  a 
  gage 
  at 
  the 
  

   ground. 
  

  

  Profs. 
  Alexander 
  D. 
  Bache 
  and 
  Joseph 
  Henry, 
  and 
  Mr 
  Desmond 
  

   FitzGerald 
  have 
  studied 
  the 
  question 
  extensively 
  in 
  this 
  country. 
  

   Mr 
  FitzGerald's 
  results 
  may 
  be 
  found 
  in 
  the 
  Journal 
  of 
  the 
  Asso- 
  

   ciation

  1884.

  Mr 
  FitzGerald 
  kept 
  two 
  gages, 
  one 
  at 
  a 
  hight 
  of 
  2 
  feet 
  6 
  inches 
  

   above 
  the 
  level 
  of 
  the 
  ground, 
  and 
  the 
  second 
  at 
  a 
  distance 
  of 
  150 
  

   feet 
  from 
  the 
  first, 
  and 
  at 
  an 
  elevation 
  of 
  20 
  feet 
  4 
  inches 
  above 
  

   the 
  lower 
  gage. 
  Both 
  gages 
  were 
  14.85 
  inches 
  in 
  diameter.
