  of

  is 
  about 
  to 
  make 
  an 
  extensive 
  addition 
  to 
  its 
  

   building. 
  The 
  cost 
  of 
  the 
  improvement 
  is 
  estimated 
  at 
  $239,000, 
  and 
  an 
  

   appeal 
  for 
  help 
  is 
  made 
  to 
  the 
  friends 
  of 
  the 
  Academy. 
  The 
  botanical 
  

   fraternity 
  are 
  interested 
  in 
  the 
  movement,

  the 
  Academy 
  possesses 
  one 
  

   of

  great 
  American 
  collections 
  of 
  plants,

  Dr. 
  George 
  Thurber'r 
  recent 
  death 
  has 
  called 
  forth 
  an 
  excellent 
  

   Short 
  biographical 
  sketch 
  in 
  Garden 
  and 
  Rmst 
  (April 
  9), 
  in 
  which 
  he 
  is 
  

   said 
  to 
  have 
  been 
  " 
  the 
  most 
  accomplished 
  horticultural 
  writer 
  America 
  

   has 
  produced." 
  He 
  was 
  born 
  in 
  Providence, 
  R. 
  L, 
  in 
  1821, 
  and 
  had 
  his 
  

   botanical 
  interests 
  aroused 
  by 
  Dr. 
  Torrev, 
  through 
  whom 
  he 
  secured 
  the 
  

   position 
  of 
  naturalist 
  on 
  the 
  Mex. 
  Bound. 
  Survey. 
  His 
  collections 
  were 
  

   very 
  nch, 
  and 
  among 
  them 
  a 
  new 
  genus 
  of 
  mallows 
  was 
  called 
  Thur- 
  

   beria 
  by 
  Dr. 
  Gray. 
  The 
  chief 
  part 
  of 
  his 
  subsequent 
  life 
  was 
  spent 
  as 
  

   editor 
  of 
  the 
  Americaii 
  Jgriculturist, 
  a 
  position 
  which 
  he 
  filled 
  for 
  22 
  

   years, 
  resigning 
  in 
  1885 
  on 
  account 
  of 
  failing 
  health. 
  In 
  botany, 
  his 
  

   name 
  is 
  chiefly 
  associated 
  with 
  the 
  grasses, 
  and 
  it 
  is 
  to 
  be 
  regretted 
  that 
  

   his 
  111 
  health 
  and 
  editorial 
  duties 
  did 
  not 
  permit 
  him 
  to 
  prepare 
  the 
  

   monograph 
  he 
  had 
  intended.
