  which 
  would 
  require 
  to 
  be 
  balanced 
  by 
  an 
  excessively 
  rapid 
  

   eastward 
  drift. 
  Furthermore, 
  the 
  formation 
  of 
  cyclonic 
  vor- 
  

   tices 
  discharging 
  into 
  the 
  eastward 
  drift 
  and 
  distorting 
  it, 
  also 
  

   retards 
  the 
  eastward 
  velocity. 
  It 
  is 
  along 
  these 
  lines 
  that 
  a 
  

   more 
  probable 
  explanation 
  of 
  the 
  existing 
  moderate 
  eastward 
  

   motion 
  may 
  be 
  found 
  than 
  in 
  the 
  Ferrel 
  theory, 
  which 
  has 
  been 
  

   widely 
  accepted 
  by 
  students. 
  

  

  There 
  is 
  a 
  chapter 
  treating 
  of 
  the 
  barometric 
  diurnal 
  wave 
  

   and 
  its 
  relation 
  to 
  the 
  magnetic 
  diurnal 
  vectors, 
  as 
  developed 
  

   in 
  Bulletin 
  No. 
  21, 
  1898, 
  together 
  with 
  a 
  comparison 
  of 
  the 
  

   diurnal 
  components 
  of 
  the 
  motion 
  of 
  the 
  atmosphere 
  locally, 
  

   which 
  shows 
  some 
  interesting 
  relations. 
  I 
  have 
  been 
  unable, 
  

   in 
  the 
  time 
  at 
  my 
  disposal, 
  to 
  utilize 
  the 
  new 
  general 
  tables 
  of 
  

   motion 
  in 
  connection 
  with 
  the 
  vectors 
  just 
  described. 
  Some- 
  

   thing 
  has 
  been 
  done 
  in 
  the 
  way 
  of 
  a 
  theory 
  of 
  the 
  local 
  cyclone 
  

   and 
  the 
  tornado, 
  which 
  is 
  promising, 
  though 
  its 
  completion 
  

   must 
  be 
  postponed 
  to 
  a 
  future 
  day. 
  I 
  have 
  been 
  most 
  effi- 
  

   ciently 
  assisted 
  in 
  this 
  work 
  by 
  the 
  faithful 
  labor 
  of 
  Messrs. 
  H. 
  

   H- 
  Kimball, 
  H. 
  L. 
  Heiskell 
  and 
  H. 
  H. 
  Dean, 
  who 
  have 
  taken 
  

   great 
  interest 
  in 
  the 
  observations 
  and 
  the 
  computations. 
  The 
  

   Chief 
  of 
  the 
  Weather 
  Bureau 
  has 
  always 
  placed 
  at 
  our 
  disposal 
  

   all 
  the 
  resources 
  of 
  the 
  office, 
  and 
  the 
  other 
  officials 
  have 
  uni- 
  

   formly 
  rendered 
  all 
  the 
  aid 
  in 
  their 
  power.
