  Fluctuations 
  

  

  From 
  a 
  scientific 
  point 
  of 
  view 
  the 
  results 
  are 
  

   quite 
  striking. 
  From 
  the 
  practical 
  standpoint, 
  

   however, 
  the 
  question 
  is, 
  whether 
  the 
  " 
  Ha- 
  

   waii 
  " 
  and 
  other 
  fertile 
  varieties 
  are 
  adequate 
  

   to 
  yield 
  seedlings, 
  which 
  will 
  surpass 
  the 
  

   infertile 
  " 
  Cheribon 
  " 
  cane. 
  Now 
  " 
  Hawaii 
  " 
  

   averages 
  14# 
  and 
  " 
  Cheribon 
  " 
  19$, 
  and 
  it 
  

   is 
  easily 
  understood 
  that 
  a 
  " 
  Hawaii 
  ' 
  seed- 
  

   ling 
  with 
  more 
  than 
  19% 
  can 
  be 
  expected 
  

   only 
  from 
  very 
  large 
  sowings. 
  Hundreds 
  of 
  

   thousands 
  of 
  seedlings 
  must 
  be 
  cultivated, 
  and 
  

   their 
  juice 
  tested, 
  before 
  this 
  improvement 
  can 
  

   be 
  reached. 
  Even 
  then, 
  it 
  may 
  have 
  no 
  signif- 
  

   icance 
  for 
  practical 
  purposes. 
  Next 
  to 
  the 
  

   amount 
  of 
  sugar 
  comes 
  the 
  resistance 
  to 
  the 
  

   disease 
  called 
  " 
  Sereh,' 
  and 
  the 
  new 
  race 
  

   requires 
  to 
  be 
  ameliorated 
  in 
  this 
  important 
  di- 
  

   rection, 
  too. 
  Other 
  qualities 
  must 
  also 
  be 
  con- 
  

   sidered, 
  and 
  any 
  casual 
  deterioration 
  in 
  

   other 
  characters 
  would 
  make 
  all 
  progress 
  

   illusory. 
  For 
  these 
  reasons 
  much 
  time 
  is 
  re- 
  

   quired 
  to 
  attain 
  distinct 
  improvements. 
  

  

  These 
  great 
  difficulties 
  in 
  the 
  way 
  of 
  selecting 
  

   extremes 
  for 
  vegetative 
  propagation 
  are 
  of 
  

   course 
  met 
  with 
  everywhere. 
  They 
  impede 
  the 
  

   work 
  of 
  the 
  breeder 
  to 
  such 
  a 
  degree, 
  that 
  but 
  

   few 
  men 
  are 
  able 
  to 
  surmount 
  them. 
  Breeding 
  

   new 
  varieties 
  necessitates 
  the 
  bending 
  of 
  every 
  

   effort 
  to 
  this 
  purpose, 
  and 
  a 
  clear 
  conception 
  of
