It  will  be  seen  from  this  return  that  tapping  went  on  for  a 
sufficiently  long  period  to  enable  one  to  determine  if  blooming 
had  anything  to  do  with  the  diminished  output  in  the  previous 
case.  That  it  has,  is  proved  beyond  doubt  by  these  returns.  The 
greatest  amount  of  pressed  rubber  produced  in  a day  was,  in 
the  case  of  the  first  lOo  trees,  II2  oz.  when  the  trees  were  then 
first  about  done  fruiting.  The  greatest  amount  produced  in  a 
day,  in  the  case  of  the  second  loo  trees,  was  6i  oz.  a sufficiently 
small  output  to  justify  the  belief  that  blooming  plays  a very  im- 
portant part  indeed  in  the  economy  of  these  trees ; therefore,  the 
lesson  is  that  on  no  account  should  a tree  be  tapped  when  it  is 
in  flower. 
Experiments  were  continued  for  a time  with  the  ten  large  trees 
previously  reported  upon,  and  for  the  reason  that  these  trees  were 
also  in  bloom,  operations  were  brought  to  a close.  Below  is  a re-
