a([UCOus  and  not  nearly  as  abundani,  In  addition  to  which,  it  is  also 
said  to  contain  a laro^er  [)ercentage  of  resinous  matter. 
Much  has  been  said  of  the  advantage  to  be  derived  from  the 
reopening  of  fresh  wounds,  giving  rise  to  that  phenomenon  often 
alluded  to  as  the  “wound  effect”.  On  the  advice  of  Mr.  W.  W. 
Railev,  of  Lowlands  Lstate,  Klang,  who  witnessed  the  tapping  one 
morning,  this  experiment  was  tried.  On  the  i6th  April,  one  hun- 
dred trees  gave  a yield  of  8o  oz.  of  pressed  rubber.  On  the  i8th 
April,  the  incisions  made  (four  to  each  tree)  on  the  i6th  April  to 
the  hundrt  (1  trees  w ere  reopened  resulting  in  58 J oz.  of  pressed 
rubber,  or  a sudden  drop  of  21  j oz  . This  certainly  seems  to  point 
out  that  reopening  an  old  wound  is  not  to  be  recommended. 
A sample  case  of  about  60  lbs.  of  rubber  prepared  by  different 
methods  has  been  seiU  to  London  for  sale.  The  result  of  this  small 
shipment  will  in  due  course  appear  in  the  columns  of  the  bulletin. 
Below  is  a continuation  of  the  table  of  the  output  of  rubber  pre-

Conjointly  wdth  the  above,  ten  large  trees  growdng  under  much 
more  favourable  conditions  than  the  hundred  alluded  to  have  on 
alternate  days  been  tapped.  1 he  total  circumference  of  these  trees 
at  four  feet  from  the  ground  was  56  feet  7 inches.'  'I  he  largest 
tree  has  a circumference  of  9 feet  (tri-branched  at  3 feet  6 inches 
from  the  base)  and  the  smallest  of  4 feet  4 inches.  All  these  trees 
have  on  previous  occasions  been  very  heavily  tapped  wdth  the 
herring  bone  incisions  on  and  off  for  the  last  t(m  yi^ars.  d'heir
