  As 
  stated 
  above, 
  a 
  definitive 
  reduction 
  of 
  all 
  Table 
  Mountain 
  observa- 
  

   tions 
  is 
  being 
  vigorously 
  pushed. 
  

  

  (h) 
  Montesuvia, 
  Chile. 
  — 
  This, 
  our 
  best 
  solar 
  constant 
  station, 
  was 
  

   also 
  in 
  continuous 
  observation 
  during 
  the 
  entire 
  year. 
  Its 
  daily 
  

   results 
  were 
  published 
  on 
  the 
  United 
  States 
  weather 
  maps 
  of 
  the 
  next 
  

   following 
  days; 
  also, 
  telegraphic 
  advices 
  were 
  sent 
  daily 
  to 
  the 
  Ar- 
  

   gentine 
  Government, 
  and 
  to 
  Dr. 
  Julio 
  Bustos 
  Navarette, 
  who 
  pub- 
  

   lishes 
  a 
  monthly 
  meteorological 
  bulletin 
  containing 
  them. 
  

  

  As 
  stated 
  above, 
  a 
  definite 
  re-reduction 
  of 
  the 
  Montezuma 
  work 
  has 
  

   been 
  completed, 
  and 
  the 
  results 
  are 
  now 
  being 
  published 
  in 
  final 
  form. 
  

  

  At 
  the 
  suggestion 
  of 
  Doctor 
  Dobson, 
  of 
  Oxford, 
  England, 
  a 
  copy 
  

   of 
  his 
  atmospheric 
  ozone 
  measuring 
  apparatus 
  has 
  been 
  installed 
  at 
  

   Montezuma, 
  and 
  its 
  daily 
  results 
  are 
  forwarded 
  to 
  Doctor 
  Dobson 
  for 
  

   reduction 
  and 
  publication. 
  

  

  (c) 
  Mount 
  Bnikkaros^ 
  South 
  West 
  Afnca. 
  — 
  The 
  solar 
  radiation 
  ex- 
  

   pedition 
  of 
  the 
  National 
  Geographic 
  Society, 
  in 
  cooperation 
  with 
  the 
  

   Smithsonian 
  Institution, 
  was 
  fully 
  equipped 
  and 
  sent 
  forward 
  in 
  

   August, 
  1926. 
  Meanwhile, 
  the 
  observatory 
  itself 
  was 
  being 
  prepared 
  

   by 
  Mr. 
  Dryden, 
  of 
  Keetmanshoop, 
  South 
  West 
  Africa, 
  under 
  Govern- 
  

   ment 
  auspices. 
  A 
  little 
  later 
  a 
  telephone 
  line 
  was 
  installed 
  by 
  Colonel 
  

   Venning, 
  director 
  of 
  posts 
  and 
  telegraph, 
  of 
  Windhoek. 
  

  

  The 
  expedition 
  (W. 
  H. 
  Hoover, 
  director, 
  F. 
  W. 
  Greeley, 
  assistant) 
  

   reached 
  the 
  mountain 
  in 
  October, 
  1926, 
  made 
  preliminary 
  observa- 
  

   tions 
  in 
  November, 
  and 
  began 
  regular 
  daily 
  observing 
  in 
  December. 
  

  

  It 
  is 
  yet 
  too 
  early 
  to 
  decide 
  how 
  satisfactory 
  atmospheric 
  con- 
  

   ditions 
  at 
  this 
  observatory 
  will 
  prove 
  to 
  be. 
  During 
  a 
  considerable 
  

   part 
  of 
  the 
  time 
  they 
  have 
  been 
  first 
  class. 
  Old 
  residents 
  maintain 
  

   that 
  during 
  the 
  unfavorable 
  time 
  the 
  weather 
  has 
  been 
  unusual, 
  and 
  

   that 
  other 
  years 
  will 
  prove 
  much 
  better. 
  This 
  view 
  is 
  supported 
  

   to 
  some 
  extent 
  by 
  the 
  weather 
  of 
  Montezuma, 
  Chile, 
  which 
  seems 
  to 
  

   be 
  in 
  some 
  degree 
  parallel. 
  Atmospheric 
  conditions 
  have 
  undoubtedly 
  

   been 
  unusually 
  bad 
  at 
  Montezuma 
  during 
  the 
  times 
  when 
  Mount 
  

   Brukkaros 
  reported 
  unfavorable 
  conditions.
