a very  little  being  produced  then.  Thence  there  was  a tolerably 
steady  increase.  On  the  13th  a hundred  trees  were  tapped  with 
two  incisions  in  the  morning  and  afternoon,  giving  17  oz.  alto- 
gether. The  sudden  increase  from  the  13th  onwards  was  undoubt- 
edly due  to  the  rainfall  which  commenced  at  that  time.  It  will  be 
noticed  that  40  trees  with  five  incisions  each  give  as  much  latex 
as  20  with  ten  incisions  and  loo  with  two,  which  shows  that  each 
cut  gives  approximately  the  same  amount,  and  the  return  depends 
more  on  the  amount  of  incisions  than  on  the  size  of  the  tree. 
It  was  noticed  that  a tree  which  at  one  time  produced  but  little 
rubber,  after  being  cut-  10  days  in  succession,  suddenly  became 
very  productive.  It  is  probable  that  some  trees  which  may  contain 
a very  fair  amount  of  latex,  require  a larger  period  of  “calling” 
than  others. 
.Another  curious  phenomenon  was  that  after  the  hot  and  dry 
season  when  the  rains  commenced  the  old  wounds  which  had  long 
ceased  to  flow,  suddenly  after  a violent  shower,  broke  out  again 
and  produced  long  tears  of  rubber.
