  Especially 
  noteworthy 
  are 
  the 
  numerous 
  investigations 
  of 
  the 
  

   Desert 
  laboratory 
  at 
  Tucson, 
  Arizona, 
  devoted 
  particularly 
  to 
  the 
  

   fundamental 
  features 
  of 
  growth, 
  nutrition 
  and 
  metabolism 
  of 
  

   plants 
  of 
  arid 
  regions 
  ; 
  the 
  director 
  of 
  the 
  laboratory, 
  Dr. 
  Mac- 
  

   Dougal, 
  has 
  had 
  a 
  large 
  part 
  in 
  the 
  many 
  investigations 
  of 
  which 
  

   a 
  digest 
  is 
  given 
  in 
  the 
  volume. 
  Another 
  epoch-making 
  advance 
  

   is 
  the 
  completion 
  of 
  the 
  100-inch 
  Hooker 
  telescope, 
  described, 
  

   with 
  a 
  summary 
  of 
  the 
  important 
  results 
  already 
  obtained 
  with 
  

   it, 
  by 
  the 
  director, 
  Dr. 
  George 
  E. 
  Hale. 
  The 
  pages 
  (217-264) 
  

   devoted 
  to 
  these 
  subjects 
  are 
  some 
  of 
  the 
  most 
  interesting 
  and 
  

   original 
  in 
  matter 
  that 
  the 
  present 
  volume 
  contains. 
  

  

  The 
  total 
  sum 
  appropriated 
  by 
  the 
  Institution 
  during 
  1919 
  was 
  

   $1,612,602 
  which 
  has 
  been 
  exceeded 
  only 
  once, 
  namely, 
  in 
  1914 
  ; 
  

   of 
  this 
  sum 
  nearly 
  $850,000 
  was 
  for 
  the 
  large 
  projects. 
  Twenty- 
  

   nine 
  volumes 
  have 
  been 
  issued 
  in 
  the 
  year 
  aggregating 
  8,265 
  

   pages. 
  Since 
  its 
  beginning 
  four 
  hundred 
  and 
  one 
  volumes 
  have 
  

   been 
  sent 
  out 
  by 
  the 
  Institution 
  embracing 
  a 
  total 
  of 
  more 
  than 
  

   111,000 
  pages.
