  varieties 
  have 
  also 
  been 
  introduced 
  from 
  Bogota, 
  Colombia 
  (Nos. 
  

   26126 
  to 
  26129). 
  

  

  The 
  Arracacia 
  of 
  South 
  America 
  forms 
  a 
  staple 
  food 
  of 
  the 
  Vene- 
  

   zuelans, 
  who 
  know 
  it 
  under 
  the 
  name 
  of 
  apio. 
  It 
  is 
  cultivated 
  in 
  

   high 
  altitudes 
  and 
  requires 
  a 
  long 
  season 
  in 
  which 
  to 
  mature. 
  It 
  

   deserves 
  a 
  thorough 
  trial 
  in 
  the 
  South 
  to 
  determine 
  where 
  it 
  will 
  suc- 
  

   ceed.

  The 
  destructive 
  fungous 
  disease 
  of 
  the 
  chestnut, 
  which 
  threatens 
  to 
  

   destroy 
  the 
  native 
  chestnut 
  trees 
  of 
  the 
  Atlantic 
  coast 
  region, 
  makes 
  

   the 
  production 
  of 
  a 
  chestnut-chinquapin 
  hybrid 
  of 
  unusual 
  interest, 
  

   since 
  its 
  resistance 
  to 
  this 
  bark 
  disease 
  may 
  furnish 
  a 
  way 
  out 
  of 
  a 
  

   situation 
  which 
  seriously 
  threatens 
  the 
  chestnut 
  industry. 
  Doctor 
  

   Van 
  Fleet's 
  hybrids 
  (Nos. 
  26230 
  to 
  26235) 
  have 
  so 
  far 
  shown 
  a 
  high 
  

   degree 
  of 
  immunity 
  to 
  the 
  disease. 
  

  

  The 
  interest 
  in 
  the 
  Japanese 
  flowering 
  cherry 
  trees, 
  which 
  have 
  been 
  

   found 
  to 
  succeed 
  well 
  in 
  the 
  United 
  States, 
  makes 
  it 
  worth 
  while 
  to 
  

   call 
  attention 
  to 
  seven 
  Chinese 
  flowering 
  cherry 
  trees 
  from 
  the 
  Yangtze 
  

   Valley, 
  collected 
  by 
  Mr. 
  E. 
  H. 
  Wilson, 
  of 
  the 
  Arnold 
  Arboretum. 
  

   (Nos. 
  26246 
  to 
  26252.) 
  

  

  For 
  many 
  years 
  attempts 
  have 
  been 
  made 
  to 
  introduce 
  the 
  cliff- 
  

   grown 
  tea 
  and 
  the 
  teas 
  from 
  the 
  Dragon 
  Pool, 
  of 
  the 
  Kienningfu 
  and 
  

   Wuishan 
  districts 
  of 
  China, 
  but 
  without 
  success. 
  Through 
  the 
  kind 
  

   assistance 
  of 
  Mr. 
  Rockhill, 
  ambassador 
  to 
  Russia, 
  formerly 
  American 
  

   ambassador 
  to 
  China, 
  and 
  the 
  hearty 
  cooperation 
  of 
  the 
  American 
  

   consul 
  and 
  vice-consul 
  at 
  Foochow, 
  fourteen 
  varieties 
  of 
  these 
  spe- 
  

   cially 
  noted 
  teas 
  have 
  been 
  introduced 
  and 
  are 
  being 
  propagated.

  as 
  

   well 
  as 
  that 
  on
