  That 
  no 
  fact 
  of 
  any 
  value 
  bearing 
  on 
  this 
  question 
  can 
  be 
  obtained 
  

   by 
  an 
  examination 
  of 
  the 
  annual 
  mean 
  temperature 
  can 
  readily 
  be 
  shown 
  

   by 
  a 
  few 
  examples. 
  For 
  instance, 
  the 
  extreme 
  variation 
  of 
  the 
  annual 
  

   mean 
  at 
  Fort 
  Leavenworth 
  for 
  40 
  years 
  is 
  only 
  7.83°, 
  and 
  the 
  extreme 
  

   variation 
  from 
  1SG0 
  to 
  1870 
  is 
  only 
  5.20° 
  ; 
  at 
  Muscatine, 
  Iowa, 
  for 
  25 
  

   years 
  it 
  is 
  but 
  8.13°; 
  at 
  Fort 
  Snelling, 
  Minn., 
  for 
  42 
  years 
  it 
  is 
  only 
  8.40°. 
  

  

  The 
  following 
  tables 
  of 
  temperature 
  and 
  rainfall 
  for 
  the 
  years 
  1872 
  to 
  

   1878 
  are 
  extracted 
  from 
  the 
  annual 
  reports 
  of 
  the 
  Signal 
  Service 
  Bureau. 
  

   The 
  records 
  of 
  the 
  different 
  stations 
  are 
  brought 
  together 
  so 
  that 
  the 
  

   variations 
  may 
  be 
  readily 
  seen 
  by 
  running 
  the 
  eye 
  over 
  the 
  columns.
