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 ioo trees, 1 12 oz. when the trees were then 
first about done fruiting. The greatest amount produced in a 
day, in the case of the second ioo trees, was 61 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-
