Observer  of  December  8,  1902,  it  is  learned  that  the  Ceylon  rubber 
referred  to  was  produced  by  Mr.  HOLLOW AV,  on  the  Kepitigalla 
estate,  besides,  the  very  good  prices  finally  obtained  for  this  rubber 
are  given,  as  follows 
4 cases  valued  at  3v.  i id.,  sold  at  4V. 
8 cases  valued  at  3V.  lid.  sold  at  4V. 
I case  scrap,  valued  at  2s.  Zd.,  sold  at  2s.  \od. 
These  cases  contained  50  pounds  each,  except  in  the  case  of  the 
scrap,  which  weighed  42  pounds  the  total  being  642  pounds,  and 
the  proceeds  1 25.1 2.S'.  (§611.23.) 
Mr.  H.  G.  Tippett,  managing  director  of  the  Liverpool  Rubber 
Co.,  Limited,  who  has  used  some  of  the  Ceylon  rubber,  says  in 
regard  to  it,  in  a letter  to  The  India  Rubber  World  : ‘‘  The  weight 
of  the  cases  at  present  is  irregular,  roughly  about  100  to  130  pounds, 
but  they  will  probaby  settle  down  as  the  supply  becomes  regular 
to  I cwt.  (112  pounds)  cases.  The  rubber  is  excellent  made  up  in 
round  pancakes  (just  like  buckwheat  cakes),  about  ^th  inch  thick, 
and  6 inches  diameter;  semi  translucent  absolutely  clean  and  drv 
loss  about  1 per  cent.  Quality  equal  to  fines  Bolivian  Para. 
At  the  London  rubber  auction  on  January  23,  sales  included  19

RUBBER  TAPPING  EXPERIMENTS  IN  THE 
BOTANIC  GARDENS. 
Conti  uiing  the  observations  on  the  tapping  experiments  in  the 
economic  section  of  the  Botanic  Gardens,  it  was  observed  that  when 
the  trees  were  first  tapped,  the  side  of  the  trunk  exposed  to  the 
heat  of  the  morning  sun,  gave  a. smaller  flow  of  latex  than  the 
opposite  or  unexposed  surface.  Subsequent  experiments  however 
prove  this  not  to  be  quite  the  case,  and  at  present,  any  side  of  the 
trunk  flows  with  equal  freedom. 
There  can  be  no  doubt  that  in  very  dry  weather,  the  flow  of  latex 
is  considerably  decreased.  A glance  at  the  table  below  will  illus- 
trate this.  The  weather  has  been  getting  gradually  dry  of  late  and 
from  the  14th  to  the  24th  April,  hardly  any  rain  fell  and  as  will  be 
seen  in  this  table,  the  output  of  rubber  during  that  period,  very 
materially  declined.  In  periods  of  drought,  tapping  should  be 
altogether  stopped.  One  result  of  the  experiments  conducted  here, 
prows  that  the  flow  of  latex  is  more  copious,  thicker  and  therefore 
('ontains  more  rubber,  at  from  the  base  to  say  about  a height  of 
four  feet  on  the  trunk  of  a tree.  Higher  up,  the  latex  is  more
